Studies of disruptive depletions of renewable resources and of severe pollution of marine and terrestrial ecosystems, for example, regularly point to deficiencies in prevailing structures of property or use rights as a principal source of these problems. Similarly, many proposals aimed at eliminating emissions of CFCs and curtailing emissions of greenhouse gases focus on changes in the rights and rules governing the behavior of those responsible for such problems. This Scoping Report seeks to define the Institutional Dimensions of Global Change (IDGC) as a coherent field of study for those concerned with the dynamics of global environmental change and to spell out a set of analytical priorities to guide research in this field. An IDGC Science Plan describing specific projects within this area of research is expected to be ready by the end of 1997. The Place of Institutions on the IHDP Agenda The IHDP program contains two sets of projects: (1) those dealing with substantive concerns like Land-Use and Land-Cover Change (LUCC) and Industrial Transformation (IT) and (2) those dealing with cross-cutting themes like institutions and individual perceptions and cognition. The intention is to produce a set of linked studies that add substantially to our understanding of the human dimensions of global change rather than a laundry list of unrelated projects. The Focus on Institutions The IDGC project casts a wide net in setting boundaries on the universe of social institutions to be considered in examining anthropogenic drivers and human responses to largescale environmental change. Markets or exchange systems are just a much a part of this universe as familiar political systems. Institutions vary along a number of important dimensions including number of members, functional scope, geographical domain, degree of role differentiation, extent of formalization, density of rules and programs, nature of associated organizations, and stage in the institutional lifecycle. The project will devote special attention to interactions among institutions operating at the local, national, and international levels. Critical Concerns and Key Science Questions IHDP Institutions July 25, 2016 4 The basic architecture of the IDGC project is straightforward. It directs attention in the first instance to studies of the effectiveness and the robustness of social institutions, issues which constitute cutting-edge concerns among students of institutions and which are of obvious relevance to understanding the roles that institutions play as social drivers and as key elements of responses to environmental changes. The report then singles out three clusters of issues that are high on the agenda of institutional analysis at the present time and that seem attractive as areas in which a program of studies carried out under the auspices of the IDGC project can produce substantial added value in efforts to improve understanding of the role of institutions in human affairs. These are the problems of scale, interplay, and fit. The problem of scale centers on the extent to which it is possible to scale up and scale down propositions relating to institutions in the dimensions of space and time. The problem of interplay involves the study of linkages or interactions among institutions operating at different levels of social organization (vertical interplay) as well as at the same level of social organization (horizontal interplay). The problem of fit directs attention to the relationships between institutions and the biophysical and social settings within which they operate. Links to Other Global Change Projects The IDGC project is intended to bring the prism of institutional analysis to bear on key global change issues of concern to other core projects and particularly LUCC, IT, and Land-Ocean Interactions in the Coastal Zone (LOICZ). In the case of LUCC, this means asking (1) How do institutions affect patterns of land use on the part of human groups operating at various levels of social organization? and (2) What roles do institutions play as determinants of human responses to changes - both anthropogenic and biogenic - in patterns of land cover? Questions relating to industrial transformation include (3) What roles do institutions play as determinants of macro-level changes in economic systems over time? and (4) How do institutions affect processes of materialization and dematerialization at different levels of social organization? Similar questions pertaining to LOICZ ask (5) How do institutions affect the nature and distribution of human activities taking place in the coastal zone? and (6) What roles do institutions play as determinants of human responses to largescale natural forces (e.g. hurricanes, tidal waves, ENSO phenomena)? Integration with Other Global Change Models A project on the institutional dimensions of global change must endeavor to frame findings in terms that facilitate efforts to integrate these findings with other global change projects, especially those carried out by natural scientists. This means formulating propositions in quantitative terms wherever possible and employing longer time frames than is usual in the social sciences. It also suggests making use of the analytical toolbox of formal IHDP Institutions July 25, 2016 5 modeling generally and the "rational choice" paradigm more specifically as an integrating framework for IDGC studies. Integrative Activities Several cross-cutting issues of a conceptual and methodological nature require attention in order to maximize the prospects for producing cumulative results from the IDGC project. The most important of these involve (1) devising a common language to facilitate communication regarding institutions among analysts coming from different social science disciplines, (2) achieving analytic harmonization or calibration as a basis for empirical studies of institutions, (3) developing databases to support comparative empirical research on institutions, and (4) comparing the results produced by individual studies of institutions in the interests of building a collection of design principles. Programmatic Links and Next Steps The IDGC project is predicated on the observation that a considerable volume of high quality research on institutions has already been carried out, is in progress, or is presently on the drawing boards. The major goals of the project are thus to (1) integrate, refine and extend existing findings that are relevant to global environmental change, (2) stimulate and coordinate research efforts aimed at filling important gaps and pursuing particularly promising areas of study, and (3) bring this intellectual capital to bear on the concerns of projects like LUCC, IT, and LOICZ. To this end those responsible for the IDGC project will consult regularly with the relevant science community in moving from this Scoping Report to the formulation of a more detailed Science Plan. An IDGC Scientific Planning Committee will coordinate this effort with the goal of producing a Science Plan for the project by the end of 1997. IHDP Institutions July 25, 2016 6 1. Introduction3 Institutions - constellations of rights, rules, and relationships that define social practices and guide interactions among those who participate in them - have been recognized as an important factor in understanding both the anthropogenic drivers of global environmental changes and human responses to such changes from the earliest days of the International Human Dimensions Programme (IHDP).4 During its first several years of operation, however, the IHDP was unable to develop a project focusing specifically on the role of social institutions. In 1995, the programme's Scientific Committee (SC) decided to take action in this area and enlisted the two of us to take the lead in exploring prospects for the development of a core project on the Institutional Dimensions of Global Change (IDGC). This Scoping Report constitutes a major step along the road toward that goal. Assuming that the IHDP SC approves the report and asks us to proceed, the next step will be the framing of an IDGC Science Plan. Work on this plan is expected to be the top priority in this area during 1997. The basic architecture of the IDGC core project is straightforward. We seek to answer questions of interest to other global change projects, including Land-Use and Land-Cover Change (LUCC), Industrial Transformation (IT), and Land-Ocean Interactions in the Coastal Zone (LOICZ), by analyzing factors that determine the effectiveness and the robustness of social institutions and, more specifically, by focusing on the problems of scale, interplay, and fit which constitute cutting-edge concerns among students of 3. Although many people have made suggestions that have proven helpful in the preparation of this report, we wish to offer particular thanks to those who assisted us by participating in a two-day workshop on the institutional dimensions of global change in January 1996: Clark Gibson, Harold Jacobson, Robert Keohane, Leslie King, and Gail Osherenko. 4. Prior to 1996, the programme was known as the Human Dimensions Programme (HDP). With the addition of ICSU as one of the programme's sponsors, however, the name was changed to IHDP. For convenience, we refer to the IHDP throughout this report. IHDP Institutions July 25, 2016 7 institutions at this time. With respect to LUCC, we ask: (1) How do institutions affect patterns of land use on the part of human groups at various levels of social organization? and (2) What roles do institutions play as determinants of human responses to both natural and anthropogenic changes in patterns of land cover? In the case of IT, we want to know (3) What roles do institutions play as determinants of macro-level changes in economic systems over time? and (4) How do institutions influence processes of materialization and dematerialization of industrial production both across societies operating at the same level of social organization and across levels of social organization? Turning to LOICZ, we enquire (5) How do institutions affect the nature and distribution of human activities taking place in the coastal zone? and (6) What roles do institutions play as determinants of human responses to natural disasters or extreme natural events (e.g. hurricanes, tidal waves, ENSO phenomena, sea-level rise) impacting the coastal zone? 2. The Place of Institutions on the IHDP Agenda In developing the research agenda of the International Human Dimensions Program, the various Steering Committees have initiated planning activities in several fields. For analytical purposes, it is useful to distinguish among four kinds of themes that have been covered in these efforts: • substantive areas of physical change and/or human activities causing such change. Major topics here include land use and land cover change, energy production and consumption, and water use. • social and technological processes determining the human impact on the environment IHDP Institutions (and, in turn, being themselves affected by July 25, 2016 8 environmental change). In this category, most attention has been devoted to demographic change and industrial transformation. • actor attributes or system properties shaping human activities. At the micro-level, attention has focused on individual perceptions, beliefs, attitudes, etc.; at the meso- and macro-level, on social institutions. • social values at stake:, including human health, security/peace, and - at least implicit in most contexts - sustainability. Figure 1 identifies the most important of these themes and illustrates the relationships among them. ____________________________ Figure 1 about here _____________________________ The project outlined in this report is premised on the assumption that institutions can be treated as a cross-cutting theme in the sense that institutional factors are important determinants of human behavior in virtually all areas of substantive interest to IHDP - be it energy production or land and water use. Moreover, understanding how institutions develop, operate, change, and decline can safely be counted among the core concerns of the social sciences. As such, the theme has considerable appeal to a wide range of social scientists - from economists to anthropologists and from “mainstreamers” to critical “dissenters." Located at the intersection between the core concerns of social science and the interest in understanding the human dimensions of global environmental change, an IHDP project on the role of institutions should meet a dual challenge. It must be able to tap into the fund of general knowledge that social scientists have accumulated about various types of institutions. At the same time, it must link the general study of institutions to a specific substantive setting, notably that of important IHDP Institutions July 25, 2016 9 problems of global environmental change and related human behavior. It must, in other words, mobilize prominent social scientists to bring their knowledge and analytical tools to bear upon major substantive problems of global environmental change. One important way to accomplish this objective, we believe, is to organize the IHDP agenda in terms of a matrix, in which projects focusing on substantive areas of environmental change and related human behavior (e.g. LUCC) and projects dealing with cross-cutting themes, such as institutions, intersect in strategically designed joint modules focusing on issues like the role of a particular kind of institution (e.g. property rights systems) in a particular setting (e.g. land use). If we succeed in forging these links, we think a core project on the role of institutions can become an integral and important component of the overall IHDP portfolio. 3. The Focus on Institutions The overall objective of the emerging core project on the Institutional Dimensions of Global Change is to determine the proportion of the variance both in anthropogenic impacts on large environmental systems and in human responses to global environmental changes that can be explained in terms of the operation of social institutions. Institutions constitute only one of several categories of social drivers that are relevant to global environmental change. Others include material conditions, like prevailing technology, and cognitive forces, like belief systems and values (Commoner 1972, White 1967). There is no need to argue that institutions are more important than other types of social drivers. Rather, the goals of this effort are to separate out institutional forces from other social drivers in order to pinpoint the proportion of the variance in human actions relating to global change that can be shown to flow IHDP Institutions July 25, 2016 10 from the operation of institutions and, subsequently, to explore how institutions interact with other social drivers to produce anthropogenic impacts and to determine human responses to environmental change. 3.1 The Nature of Institutions Institutions are human artifacts that are pervasive at all levels of social organization. Familiar examples include systems of property rights that guide the actions of individual users of land and natural resources and legislative arrangements that guide the process of making collective choices about publicly owned lands or about regulations to be imposed on the actions of individual land owners. The rapidly growing literature on the "tragedy of the commons," including studies of the reasons why the tragedy does not occur in many social settings featuring common property arrangements, is fundamentally a debate about the role of institutions as determinants of human actions affecting nature and natural resources (Hardin and Baden eds. 1977, McCay and Acheson eds. 1987). Similarly, recent debates regarding the extent to which public lands should be transferred into various forms of private property are premised on the idea that institutional arrangements are key factors in determining the outcomes resulting from human uses of nature and natural resources (Nelson 1995). This report casts a wide net in setting boundaries on the universe of social institutions to be considered in examining the impacts of human actions on largescale environmental systems and the responses of humans to environmental changes. Various types of markets or exchange systems are just as much a part of this universe as familiar political arrangements. Not only do exchange relationships themselves rest on well-understood rules but also markets cannot operate effectively in the absence of associated IHDP Institutions July 25, 2016 11 institutional arrangements dealing with contracts, financing, patents, liability, and exchange rates. Similarly, institutions encompass both formal and informal social practices. Thus, the common property systems developed in smallscale, traditional societies on the basis of trial and error and in the absence of explicit agreements about codes of conduct are no less important as members of the universe of institutions as the formal arrangements spelled out in legislative enactments at the national level and international conventions or treaties. As anthropologists and sociologists have often observed, moreover, institutions in operation or, as some analysts would put it, rules in use frequently include a complex mix of formal arrangements and informal practices. Over time, rules in use may move well beyond or away from formally articulated constitutive agreements. Yet these living practices are generally well understood by those whose actions they guide. Institutions come in many sizes and shapes. Both local arrangements dealing with the management of irrigation systems and international arrangements pertaining to transboundary lakes and river basins, for example, are institutions that are narrowly focused in spatial and functional terms. Other social practices, like systems of commonfield agriculture in traditional societies or the international rules governing human uses of marine areas, are cast in broader terms. It is apparent as well that in a world involving the operation of many distinct institutions at the same time, there is a need to recognize the existence of a variety of linkages among institutions that are differentiable from one another but that affect each other in significant ways (Young 1996). Because institutions are complex, students of these arrangements have exhibited an understandable tendency to focus on specific institutions as if they were stand-alone arrangements. But it is clear that institutional linkages - both intended and unintended - constitute an IHDP Institutions July 25, 2016 12 increasingly important phenomenon that will require increased attention in the future. Institutions understood as social practices are not to be confused with organizations treated as material entities possessing offices, personnel, equipment, budgets, and legal personality (Young 1994a). British Petroleum is an organization, but the world trade system embodied in the provisions of the General Agreement on Tariffs and Trade (GATT) and now the World Trade Organization (WTO) is an institution. Similarly, the United States Department of Interior is an organization, while the regimes governing mining or the harvesting of timber on public lands are institutions. The purpose of drawing this distinction is not to argue that institutions are more important than organizations or vice versa. On the contrary, the distinction opens up an important research program focusing on the roles that organizations play in the formation of social institutions and the factors that determine whether and to what extent organizations are needed to administer institutions once they have been put in place. Institutions vary along a number of important dimensions. These include number of members, functional scope, geographical domain, degree of role differentiation, extent of formalization, density of rules and programs, nature of associated organizations, and stage in the institutional lifecycle. It is important to note as well that institutions are not static; they change continuously over time in response to both endogenous and exogenous forces. In many cases, this involves the emergence of informal understandings that supplement or, in some instances, modify the formal rules and programs spelled out in constitutive documents. Under the circumstances, it is helpful to use the phrase social practices to refer to the ensembles of formal arrangements and informal understandings that are understood by the actors IHDP Institutions July 25, 2016 13 involved and that together make up rules in use or institutions as they actually operate on the ground. 3.2 Institutional Tasks and Types Preoccupied with the search for solutions to collective-action problems, many analysts have simply assumed that institutions are sets of rules or codes of conduct whose purpose is to overcome the negative consequences of individualistic behavior in interactive situations (Schelling 1978). The concern with institutional devices that smallscale societies have developed to avoid the tragedy of the commons illustrates this proposition clearly (Ostrom 1990). So also does the tendency to model arms races, trade wars, and environmental problems occurring at the macro-level in terms of analytic constructs like the prisoner's dilemma or chicken. In all these cases, the problem is to reach agreement, whether explicitly or tacitly, on regulatory arrangements and then to find ways of ensuring that most participants comply with these rules most of the time (Mitchell 1994, Chayes and Chayes 1995). Such regulatory arrangements constitute an important category of institutions at all levels of social organization. But they do not exhaust the category of institutions or, perhaps more accurately, the range of differentiable functions or tasks that institutions perform. Institutions often concentrate on procedural tasks in the sense that they provide mechanisms through which parties can make collective choices about matters of common concern (Hayek 1979). Some such choices are recurrent (e.g. setting total allowable catches of living resources on an annual basis). Others are episodic (e.g. designating certain species as threatened or endangered as the need arises). Still others are unique in the sense that they occur only once (e.g. deciding whether to dam a river to generate energy or irrigate land). But IHDP Institutions July 25, 2016 14 unlike regulatory arrangements, which feature rules (including prohibitions, requirements, and permissions) intended to apply uniformly to well-defined categories or classes of situations, procedural mechanisms allow the members of an institutional arrangement to cope with common problems on a case-bycase basis and to address new issues that were unforeseen at the time the arrangement was created. To these categories of regulatory and procedural institutions, we must add programmatic and generative arrangements. Programmatic institutions are mechanisms intended to allow groups of actors to pool their resources or coordinate their efforts in the interests of planning and carrying out projects that none would be able to mount successfully on its own. The building and maintenance of largescale infrastructure (e.g. transboundary flood control or irrigation systems) or the establishment of joint development zones (e.g. coordinated arrangements to allow for the exploitation of oil or gas deposits in an efficient manner) exemplify this type of arrangement. The essential problem here is to reach agreement on designs for common projects and then to assign well-defined roles to participants in the coordinated activities that follow. Generative institutions, by contrast, are arrangements that focus on efforts to foster understanding of complex problems and to build up the intellectual capital needed to cope with them. Often, this is a matter of devising an analytic perspective, like the ways of thinking we associate with the ideas of sustainable yields, ecosystems management, and critical loads. The articulation of such a perspective or, as many would say, guiding discourse frequently plays a role in setting agendas and in building constituencies that support the ongoing development of social practices (Litfin 1994). In this connection, institutions can function not only as sources IHDP Institutions July 25, 2016 15 of the intellectual capital needed to deal with the problem at hand but also as producers of discourses that diffuse from their origins into other issue areas. Not surprisingly, the application of such systems of thought to areas outside their original domain is often controversial. The distinctions among regulatory, procedural, programmatic, and generative arrangements are analytic in nature. The same institution may perform two or more of these tasks at the same time. Institutions addressing the consumptive use of marine living resources, for instance, may seek to (1) introduce new ways of thinking about the problem at hand (e.g. newly emerging ideas associated with the concepts of large marine ecosystems and marine biological conservation), (2) lay down rules involving gear types, seasons, or protected areas, (3) provide a procedure for setting annual harvest levels, and (4) set in motion joint projects intended to rebuild depleted stocks or degraded habitats. Nonetheless, many institutions stress one or another of these tasks, leaving others to be handled by different arrangements that may or may not be organized in a complementary fashion. Beyond this, it is pertinent to note that institutions may play broader identitive or constitutive roles in addition to the utilitarian tasks outlined in the preceding paragraphs. Mainstream thinking about social institutions assumes the prior existence of actors possessing a clear sense of their own identities and the interests flowing from these identities. Such actors will be motivated to create institutional arrangements when they find that proceeding individualistically leads to joint losses or an inability to reap joint gains. On this account, institutions are devices formed be self-interested actors to solve or at least ameliorate collective-action problems (e.g. security dilemmas, trade wars, tragedies of the commons). An identitive or constitutive perspective, on the other hand, assumes that institutions play a IHDP Institutions July 25, 2016 16 major role in defining the interests of participants and even in shaping their identities. Members of the European Union, for example, are required to make significant adjustments in their domestic systems in order to meet the requirements of membership in the union. On this account, institutions have formative effects on their members rather than the other way around (Wendt 1987, Wendt 1992). 3.3 The Institutional Agenda Those seeking to understand the operation of institutions have directed attention to the nature of the actors participating in such arrangements, the character of the interactions among the actors, and the physical, biological and social domains within which these interactions take place. With regard to the actors, there are lively debates concerning the relevance of such variables as the total number of actors, the degree of heterogeneity among the set of participants, and the extent to which participants behave as unitary actors or as collective entities (Keohane and Ostrom eds. 1995). Discussions of the relationships among actors range from analyses of the effects of role differentiation to assessments of the differences among interactions that are primarily regulatory, procedural, programmatic, or generative. Domain refers both to social considerations, like the extent and nature of feelings of community among the members of an institution, and to biological and physical considerations, like the population dynamics of stocks of fish or animals whose use on the part of humans gives rise to the institutions in the first place. The study of these matters constitutes a common agenda for those interested in the role of social institutions, and analysts representing a number of disciplines, including anthropology, economics, law, political science, and sociology, have made major contributions to our understanding of the effects of variations along all of these dimensions. IHDP Institutions July 25, 2016 17 In recent years, a movement commonly described as the "new institutionalism" has emerged and begun to play an important role in integrating the efforts of students of institutions representing most of the social science disciplines (Furubotn and Richter eds. 1991, March and Olsen 1989, Powell and DiMaggio eds. 1991, Rutherford 1994, Young 1994a). Although there is considerable variation among the different strands of this movement, its hallmarks are a focus on rules in use in contrast to formalistic perspectives on institutions and a clear distinction between institutions construed as social practices and organizations treated as material entities with offices, personnel, equipment, budgets, and so forth. The leaders of this movement have sought to shed light on (1) the processes through which institutions form or become established, (2) the effectiveness of institutions or the extent to which they impact the course of collective outcomes in various social settings, and (3) the dynamics of institutions or the forces determining both the robustness of social practices and the ways in which they change over time. It is too early to make a definitive assessment of the contributions that this "new institutionalism" will yield in efforts to broaden and deepen our understanding of social institutions. But it is already clear that this movement offers an attractive vehicle for analysts from all the social sciences to work together on a research program that is of interest to all but that is the property of none. It follows that the "new institutionalism" can provide a helpful framework for organizing our efforts to understand the role of institutions as determinants of anthropogenic drivers and human responses to global environmental changes. IHDP Institutions July 25, 2016 18 4. Critical Concerns: Effectiveness and Robustness Social science research has asked a wide range of questions about institutions. In the study of global environmental change, however, most of the interest in the role of institutions centers on two critical concerns: effectiveness and robustness. To play a significant role as anthropogenic drivers or as determinants of human responses to environmental changes institutions must be effective or, in other words, make a difference in shaping the flow of collective outcomes in various social systems. A necessary, though not sufficient, condition for institutions to make a difference is some capacity to endure or, in other words, to achieve a significant measure of robustness. 4.1 Institutional Effectiveness An institution is effective to the extent that it successfully performs a particular (set of) function(s) or solves a particular problem.5 A taxonomy of functions or tasks that institutions can perform has already been suggested in Section 3.2. In some contexts, effectiveness can be assessed in relation to a specific problem rather than a more generic function. Thus, an institution is often said to be effective to the extent that it solves or alleviates the problem that motivated its establishment.6 As we shall see, both of these approaches have their pitfalls and limitations, but the point to be made here is simply that institutional effectiveness can not be meaningfully assessed in the abstract; 5. In studies adopting a systems perspective, the concept of "efficiency" is sometimes used instead of "effectiveness" (Easton 1965). The former directs attention to the relationship between accomplishments and costs, while effectiveness is most often defined in terms of "gross" achievement. 6. In some instances, we distinguish between the official purpose of an institution and the private motives that individual actors have for contributing to its establishment and operation. The regime dealing with long-range transboundary transport of pollutants in Europe, for example, owes its existence in part to the interest of the former Soviet Union in promoting detente through the development of new mechanisms for East-West collaboration. IHDP Institutions July 25, 2016 19 any assessment of effectiveness will have to be related to a specific (set of) function(s) or to a particular problem. Evaluating effectiveness requires comparing something - let us provisionally refer to this object simply as "the institution" - against some standard of success or accomplishment. More specifically, any assessment of effectiveness will have to cope with at least three main questions: (1) What precisely is the object to be evaluated? (2) Against which standard of success is this object to be evaluated? and (3) What kind(s) of measurement operations do we have to perform in order to be able to attribute a certain level of effectiveness to an institution? We have both wrestled with these questions in some detail elsewhere (see e.g. Underdal 1992, Young 1994a). Suffice it here to offer just a few remarks to indicate the kinds of considerations involved. Regarding the object to be evaluated, the most important distinction seems to be that between the formal norms, principles and rules that constitute the institution itself and the set of consequences flowing from its operation. In the context of environmental change, the latter may be further specified by drawing a distinction between consequences in the form of changes in human behavior and consequences that materialize as changes in the state of the biophysical environment itself. We have no straightforward method for inferring behavioral change from formal characteristics of the institution itself. Actors sometimes respond by making ingenious adjustments that are hard to predict or by engaging in more or less flagrant noncompliance. Nor is the relationship between change in human behavior and change in the biophysical environment always well understood. By implication, the conclusion we end up with may depend critically upon which of these objects our assessment refers to. Defining an evaluation standard involves at least two important steps. One is to determine the point of reference against which actual achievement is IHDP Institutions July 25, 2016 20 to be compared. The other is to determine a metric of measurement. There are basically two points of reference that are commonly used in this context. One is the hypothetical state of affairs that would have come about had the institution not existed. The other is some notion of “optimum” or the “ideal” solution. The former is clearly the notion we have in mind when we ask whether a particular institution “makes a difference;” the latter is the appropriate perspective if we ask to what extent a particular problem is in fact solved or a particular purpose accomplished under present arrangements. Again, the score we would give to a particular institution may be highly sensitive to the choice of reference point. The same can be said about the choice of metric. In the study of environmental change, institutions are sometimes evaluated in terms of social welfare and sometimes in terms of ecological concepts such as “sustainability.” Failure to specify which of these (or other) standards is to be used can lead to confusion or misunderstandings. If we conceive of institutional effectiveness in terms of relative improvement compared to the situation that would have existed in its absence, we need to answer the hypothetical question of what would have happened had the institution not existed. Needless to say, this can be an intriguing methodological challenge. Determining the maximum (“optimum”) that can be accomplished in a given setting may be even more difficult. Looming over all these considerations is the fact that any measure of effectiveness has causal inferences embedded within it. To say that an institution is effective in any of the senses mentioned is to assert that it is causally significant as a determinant of the behavior of at least some of the actors involved (Levy, Young, and Zuern 1995). Not surprisingly, therefore, much of the time and energy of students of institutional effectiveness goes into efforts to pin down and demonstrate to skeptics the causal force of institutions operative in various spheres of human behavior. IHDP Institutions July 25, 2016 21 4.2 Institutional Robustness An institution is robust to the extent that it is able to cope with disturbances and survive stress. The ability of an institution to survive is - like that of any species in the biosphere - related to its ability to adapt to changing (task) environments. The relationship between robustness and adaptability is, however, a complex one, and raises intricate analytical questions at two levels. First, there is the conceptual issue of what has to remain constant for an institution to "survive." The conventional answer has been to define survival in terms of persistence of "essential" or "constitutive" characteristics - "those that best define the way in which the system operates" (Easton 1965: 92). We can easily see, however, that the distinction between “essential” and “nonessential” features can be difficult to draw in a given empirical setting. Thus, while a full-scale transition from a system of common ownership of land to one based on private property no doubt qualifies as a change in an essential characteristic of the property rights system, it is less obvious how to evaluate a marginal change affecting, say, ten per cent of the land owned by a community. Second, there is the empirical question of the causal link between adaptability and robustness. To what extent does the ability to adapt "nonconstitutive" elements to changes in its task environment increase the chances that the "core" of an institution will survive? Put differently, what is the "optimal" level of adaptability for a particular kind of institution?7 These are hard questions to answer, but it is abundantly clear that extreme rigidity is rarely if ever a good recipe for survival. The optimal level of institutional adaptability is well above zero, but also well below the theoretical maximum (see below). 7. Since robustness is intimately related to change, any enquiry into the sources of institutional change will also shed some light on the sources of robustness (Campbell, Hollingsworth, and Lindberg eds. 1991). IHDP Institutions July 25, 2016 22 Robustness, as defined above, has both an internal and an external dimension. An institution is robust, in the internal sense, if it exhibits a pronounced tendency to return to some equilibrium state in the wake of perturbations or distortions brought about by its own operations. An economic system that can weather severe business cycles and return to a more productive state is a robust system. So also is a democratic polity that can withstand long periods of dominance by a single party or faction without degenerating into despotism. External robustness, by contrast, refers to the capacity of a system to adjust to changes in its task environment or the broader setting within which it operates without losing its defining or essential characteristics. Fishery regimes that cannot tolerate significant changes in the technology used to harvest fish (e.g. the advent of the stern trawler) are lacking in robustness in this sense. So also are management regimes that prove incapable of adjusting to substantial changes in the abundance of stocks attributable to physical or biological forces. In general, there is no reason to assume that the two dimensions of robustness will vary together. Institutions that are highly robust in internal terms sometimes collapse suddenly in the wake of changes in the environment within which they operate, and vice versa. Robustness is a complex variable that is difficult to measure in any straightforward manner. Repeated surprises regarding the collapse of seemingly robust systems (e.g. the Soviet Union during 1990-91) make it clear that we are often better at assessing robustness in ex post rather than in ex ante terms (Gaddis 1992/1993). Similar comments are in order about the persistence of systems that appear to many observers to be on their last legs. In one respect, however, robustness is a more tractable variable than effectiveness. Efforts to measure robustness do not require the sorts of causal inferences that complicate the assessment of effectiveness. The position of a IHDP Institutions July 25, 2016 23 given social institution on the scale of robustness can, in other words, be measured in terms of the relationship between stress and persistence. This is by no means an easy exercise, but there is a reasonable hope that we will be able to assess robustness in ordinal terms or in terms of distinctions such as low, medium, and high. Let us conclude this section by adding a few words about the relationship between effectiveness and robustness. Other things being equal, (perceived) effectiveness seems to be a source of strength and will therefore enhance the robustness of an institution. In the long run, a certain minimum of effectiveness will probably be a necessary condition for survival. Robustness does, however, depend also on other factors, among which legitimacy appears to be the most important. The higher the general legitimacy of an institution, the less vulnerable it will be to temporary performance "failures," and the longer it can survive even more lasting problems of "malfunctioning." The impact of robustness on effectiveness is somewhat more complex. To be effective an institution must be able to survive encounters with the kind(s) of problems it has been established to solve or alleviate. In this particular sense, at least, effectiveness requires robustness. It is equally obvious, however, that effectiveness can be enhanced by the ability to learn from experience and to adapt constructively to new challenges. For example, a government that is capable of adjusting its fiscal policies in response to changes in the domestic economy or in the international financial system is likely to be more successful in achieving its basic objectives than one that fails to adjust. The bottom line is that effectiveness seems to require a particular combination of resilience and adaptability. Determining the optimal balance more precisely can be a difficult task, but the basic notion itself can at least serve as a heuristic device pointing us towards a fertile area of research. IHDP Institutions July 25, 2016 24 5. Key IDGC Science Questions A core project on the Institutional Dimensions of Global Change must focus, at one and the same time, on questions that are of obvious relevance to understanding the roles humans play in the dynamics of large biophysical systems and that are at the cutting edge of thinking about institutions more generally. It must also seek to build on the efforts of those whose work on institutions does not flow from an interest in global environmental change. Bearing these considerations in mind, we propose that an IHDP core project on institutions pay particular attention to three sets of cross-cutting analytic concerns that promise to shed light on the determinants of the effectiveness and robustness of institutions and that call for collaborative, interdisciplinary research of the type that a core project can stimulate and coordinate. These concerns include: the problem of scale, the problem of interplay among differentiable but related institutions, and the problem of fit between institutions and the biophysical and social domains within which they operate. 5.1 The Problem of Scale The problem of scale centers on the transferability of both empirical generalizations and causal inferences from one level to another in the dimensions of space and time. Thus, scaling up in space is a matter of applying findings derived from the analysis of smallscale or micro-level systems to meso-scale or even macro-scale systems. Conversely, scaling down is a process of bringing findings about largescale systems to bear on the analysis of meso-level or micro-level systems. The problem associated with scale arises from the fact that while scaling up and scaling down are relatively IHDP Institutions July 25, 2016 25 straightforward procedures under some conditions, this is not the case under other conditions. It is therefore an important challenge both to identify conditions under which generalizing across scales is hazardous and to develop procedures for adapting propositions and models to allow for scaling up or down in such cases. Natural scientists have long regarded the problem of scale as critical to determining the scope of the validity of propositions about biophysical systems and to developing integrated theories about such systems (Holling, 1992, Ehleringer and Field eds. 1993). By contrast, the problem of scale has received comparatively little attention from social scientists. Yet it is easy to see that this problem is just as relevant to the study of social or human systems as it is to the analysis of biophysical systems (Young 1994b). The assessment of the effectiveness of social institutions as determinants of collective outcomes constitutes a clear case in point. We want to know, for example, whether and to what extent the causal mechanisms through which institutions affect behavior at one level of social organization, such as smallscale or micro-level societies, also play key roles at other levels of social organization, including national (meso-level) societies and international (macro-level) society and vice versa. Similar comments are in order about the robustness of social practices. We want to identify similarities and differences in the determinants of institutional robustness and in the dynamics of social institutions operating at various levels of social organization. One obvious matter of interest in this realm concerns the relative weight of endogenous factors and exogenous forces as determinants of institutional effectiveness. Students of micro-level and meso-level arrangements typically take it for granted that institutions make a difference and set about analyzing those features of institutions themselves that account IHDP Institutions July 25, 2016 26 for variations in the results institutions produce. To some extent this is a matter of the fit between a particular institution and the problem it is created to solve, a subject to which we return in a subsequent section of this report. But beyond this, the focus on endogenous determinants of effectiveness leads naturally to a consideration of design principles. A particularly well-known example of such thinking, based on an extensive analysis of micro-level systems, can be seen in Ostrom's discussion of long-enduring common property arrangements (Ostrom 1990). No doubt, there is room for discussion regarding the persuasiveness of these principles at the micro-level. But our question in this connection concerns the extent to which these principles (summarized in Table 1) can be scaled up to apply to meso-level and, especially, macro-level situations (McGinnis and Ostrom 1992). Consider the following questions about specific principles. It may be possible for most affected actors to participate in "modifying the operational rules" at the micro-level. But how can this condition _________________________ Table 1 about here __________________________ be met at the meso-level, and is it sufficient to grant all member states (as opposed to those whose behavior is at stake) the right to participate in making such decisions at the macro-level? Do sanctions actually work at the national or meso-level in the sense that they constitute a serious deterrent to those who experience incentives to cheat, and does it make any sense to think about a system of graduated sanctions at the macro-level? Is "rapid access to low-cost local arenas to resolve conflicts" a requirement that those responsible for meso-level or macro-level institutions can meet? More generally, how do these principles, derived from a study of the behavior of appropriators of common pool resources, apply to the behavior of polluters or actors who are IHDP Institutions July 25, 2016 27 injecting wastes of various types into ecosystems in contrast to appropriating or withdrawing resources from a common pool? The point of raising these questions is not to cast doubt on the validity of the conclusions about local or micro-level institutions that Ostrom and her colleagues have reached. Rather, our purpose is to explore variations in the processes operating at different levels of social organization that may affect the transferability of propositions from one level to another. Students of international relations who focus on macro-level systems, by contrast, have devoted more attention to identifying exogenous determinants of institutional effectiveness. They ask whether certain conditions relating to the distribution of material resources, the configuration of interests, and the content of ideas are required in order to allow institutions to operate effectively. A favorite theme of this line of thinking concerns the extent to which the presence of a dominant actor in the sense of an actor able to control a preponderance of the material bases of power in the relevant issue area is needed in order for international regimes to succeed in solving problems (Keohane 1984). But other arguments pertaining to exogenous forces are easy enough to formulate. Some analysts, looking to the configuration of interests among the relevant actors, emphasize the importance of the existence of one or more equilibria yielding Pareto optimal outcomes - as in paradigm know as battle of the sexes - as a determinant of the effectiveness of institutions (Snidal 1985). Others direct attention to the convergence of ideas (Cooper 1989) or the presence of an "epistemic community" (i.e. a group of experts possessing both a common interpretation of the nature of the problem and an agreed prescription for solving it) as a condition for success (Haas ed. 1992). IHDP Institutions July 25, 2016 28 From one point of view, these arguments regarding exogenous forces diminish the role that institutions play as determinants of collective outcomes in interactive situations. Alternatively, however, we can think of them as propositions about intervening variables that limit but do not eliminate the role of institutions treated as independent variables. But be that as it may, the issue before us here is whether these arguments about macro-level systems are transferable to the study of meso-level and micro-level systems. Although the details undoubtedly differ from one level to another, there is a sense in which arguments of this kind raise age-old issues at every level of social organization. The underlying question is whether institutions are epiphenomena or surface manifestations of deeper social forces, like the distribution of power or the grip of dominant ideas, rather than determinants of behavior in their own right. Although this concern is currently voiced with particular force by those who study macro-level systems (Strange 1983), the core issue is much the same at every level of social organization. Just as realists tend to deny or diminish the significance of international regimes, Marxian analysts will see meso-level and micro-level institutions as reflections of the interests of a ruling class, and those whose thinking is Platonic or Hegelian in origin will view institutions as surface manifestations of prevailing worldviews or ideologies. Our purpose at this stage is not to say whether any of these analytic perspectives is right or wrong. But it does seem apparent that there is room for a mutually beneficial dialogue among students of institutions at all levels regarding the role of these exogenous forces. Another subject of interest to those who think about the relationship between scale and effectiveness centers on issues of equity or fairness. Analysts - particularly economists - who focus on meso-level systems often assess institutions in terms of their implications for the pursuit of efficiency (Dorfman and Dorfman eds. 1977). For the most part, they either ignore IHDP Institutions July 25, 2016 29 questions of fairness on the grounds that the consideration of such matters raises intractable questions about interpersonal comparisons of utility or argue that it is more important to think in terms of processes that are fair than in terms of consequentialist conceptions of equity that pose all the difficulties associated with the idea of social welfare (Nozick 1974). Many students of micro-level systems, by contrast, argue that fairness is an essential ingredient of effectiveness in the sense that any institutional arrangement dealing with common pool resources "must somehow win agreement from both rich and poor members of the community in order to keep either group from sabotaging the system" (McKean 1992: 275). For their part, mainstream writers on macro-level systems often deny that considerations of equity or fairness play any role at all. They view interests backed by power as the dominant force in international society, a perspective that leaves little room for any argument suggesting a link between institutional effectiveness and equity. What are we to make of these divergent points of view regarding the role of equity or fairness as a determinant of institutional effectiveness? Do they reflect fundamental differences in the nature of institutions or the roles they play from one level of social organization to another? Without denying the existence of relevant differences, it is possible to raise some pointed questions about these divergent points of view. Although it is certainly true that the identification of social welfare functions is fraught with analytic difficulties, there is no denying the importance that actors in meso-level systems attach to considerations of fairness and to the distributive consequences of institutional arrangements more generally. For their part, even the most powerful actors at the macro-level often find that it is easier and ultimately cheaper to provide weaker participants in ongoing institutional arrangements with some sense of equity regarding the outcomes than to coerce participation on the part of unwilling actors on a continuous IHDP Institutions July 25, 2016 30 basis. On the other hand, there is little evidence that micro-level arrangements dealing with common pool resources can be counted on to yield equitable outcomes in distributive terms; asymmetries in the power resources of participants and incentives to capture the lion's share of the gains from cooperation appear to be just as prevalent at this level as they are at other levels of social organization. The point of these observations is that apparent differences in the role of equity or fairness across levels of social organization may be artifacts of our analytic perspectives in contrast to real effects of scale. Until we take seriously the problem of scale in this connection and make a concerted effort to assess the transferability of propositions from one level of social organization to another, we will be unable to speak with authority about the links between considerations of equity or fairness and the effectiveness of social institutions. A third issue of interest with regard to connections between scale and effectiveness centers on the social settings within which specific institutions operate. One common concern in this realm involves the relationship between institutions and what is generally referred to as community. Many analysts of micro-level systems see social institutions as culturally embedded structures and treat the existence of a sense of community among their members as a necessary condition for the effectiveness of specific institutions. In a commentary on Ostrom's work, for example, Singleton and Taylor (1992: 309) argue that a group's capacity to solve collective-action problems endogenously (i.e. in the absence of an external public authority able and willing to impose rules) is a function of the degree to which the group "approximates a community of mutually vulnerable actors." In her response to this argument, Ostrom (1992) acknowledges the importance of community in helping to devise effective arrangements to manage the use of common pool resources. But what exactly is a community in this sense, and can this IHDP Institutions July 25, 2016 31 argument about the importance of community be generalized across levels of social organization? Singleton and Taylor (1992: 315) use the term community in a very specific sense, which they acknowledge may have a limited range of applicability to real-world situations. Others have used the term in many different ways and, more often than not, in ways that are too imprecise to allow for a serious assessment of arguments in which community figures as a variable. At the same time, Singleton and Taylor argue that their analysis can be generalized to all situations involving collective-action problems, a position implying that it is possible to scale up and scale down with regard to propositions concerning the role of community as a determinant of the effectiveness of social institutions treated as responses to collective-action problems. This suggests that there is a need to review the rather casual use of the concept on the part of students of international society (Claude 1988) and to agree on a definition that is precise enough to permit testing of specific propositions. Similar observations are relevant to the institutional setting within which specific institutions operate. Although students of social institutions often proceed by picking out individual arrangements and treating them as though they were largely self-contained, it is easy to see that many distinct institutions are closely linked to others. As von Moltke has pointed out (forthcoming), it is more accurate in many circumstances to speak of institutional structures in the sense of clusters of closely connected arrangements that deal with broad issue areas in contrast to single issues and that share a number of basic features. At the same time, it is clear that structure is a variable in the sense that the tightness of institutional structures can vary across issue areas and levels of social organization. It is probably accurate to say, for instance, that economic institutions are more tightly structured in this sense than environmental institutions and that meso-level IHDP Institutions July 25, 2016 32 institutions are more tightly structured than macro-level institutions. The question of interest to this discussion, then, is whether tightly structured arrangements are more effective than those that are loosely structured. The common expectation is that this will be the case due to processes of mutual reinforcement among linked arrangements. Yet there may also be cases in which clustering increases the danger of sudden collapse due to the absence of barriers capable of preventing disruptive forces from spreading from one institutional element to another, an observation that brings us to a consideration of the links between scale and the robustness of institutions. To what extent are the determinants of robustness similar across institutional arrangements operating at different levels of social organization? Are macro-level institutions less persistent than (1) analogous arrangements at the meso-level as a consequence of the absence of a higher authority possessing the capacity and the will to enforce key rules or (2) similar arrangements at the micro-level due to the absence of face-toface relations that maximize transparency and activate feelings of shame? Or are macro-level institutions likely to prove unusually persistent due to the underdeveloped nature of international legislative processes capable of monitoring the performance of institutional arrangements and making changes in them? Do institutions exhibit distinct lifecycles, as those who study meso-level arrangements have often suggested? If so, are these lifecycles comparable across levels of social organization or do institutions arise, flourish and decline in patterns that are different at the micro-level and the macro-level from those characteristic of the meso-level? Is the capture of institutions by particular interest groups (i.e. special interests), a phenomenon that has often been noted at the meso-level, something that occurs as well at the micro-level and the macro-level? As these questions suggest, accounts of processes affecting the persistence of social institutions have proceeded for IHDP Institutions July 25, 2016 33 the most part at a single level of social organization with little concern for similarities and differences in the operation of these processes across levels. Another perspective on robustness centers on variations in the flexibility of institutions or their capacity to adapt to changing circumstances while retaining their defining characteristics. Does the underdeveloped character of judicial procedures designed to settle disputes about the meaning of ambiguous rules or legislative procedures intended to adjust rules to changing circumstances constitute a threat to robustness at the micro-level and the macro-level in contrast to the meso-level? Are there functional equivalents operative at these levels that enhance flexibility, even though they may not resemble the familiar judicial and legislative mechanisms of the meso-level in superficial terms? Does it make sense, for example, to compare the processes usually grouped under the heading of common law in domestic settings with those associated with customary law in local and international settings? Are there parallels between the use of "soft law" arrangements at the international level as a way to deal with situations where circumstances (or our understanding of them) are changing rapidly and various administrative procedures at the meso-level and informal understandings at the micro-level? Does social learning occur at each level of social organization, and is it equally significant as a source of adaptability at the various levels? It is clear that even (or perhaps especially) institutions that are highly robust adapt on a continuous basis to shifting circumstances of both an endogenous and an exogenous nature. But what we do not understand well at this stage is the extent to which we can scale up and scale down with regard to the determinants of flexibility or adaptability in social institutions operating at the micro-, meso-, and macro-levels. IHDP Institutions July 25, 2016 34 Underlying all these questions relating to the robustness of social institutions are issues concerning the contributions of different social drivers to the dynamics of social institutions (Keohane and Nye 1977). Those who treat material conditions as master variables are apt to point to technological changes (e.g. the introduction of more powerful agricultural equipment or more efficient harvesting methods) or to shifts in the distribution of the material bases of power (e.g. the advent of a monopolist or a monopsonist) in explaining the decline of old institutions and the emergence of their replacements. Similarly, those who point to the central role of ideas will see cognitive shifts (e.g. the loss of credibility in the eyes of the attentive public of the coercive apparatus of the Soviet system) as key factors in explaining institutional change. For their part, those who look to the configuration of interests will concentrate on the analysis of shifting patterns of interests (e.g. the convergence of interests over the last several decades among members of the European Union) in their efforts to account for stability and change in social institutions. There is no need to choose among these perspectives. Shifts in material conditions can stimulate the growth of new ideas; new ideas can alter configurations of interests, changing patterns of interests can affect the distribution of material resources. But what we do want to stress here are the prospects for scaling up and scaling down with regard to the interactions among these driving forces and their roles as determinants of the robustness of social institutions. Are the processes at work sufficiently similar so that we can realistically expect to produce generalizations and causal inferences that apply to all three levels? Or are we likely to end up with different accounts of the determinants of robustness at the micro-, meso-, and macro-levels? IHDP Institutions July 25, 2016 35 5. 2 The Problem of Interplay Much current research on social institutions focuses on individual cases or specific categories of institutions as self-contained or stand-alone arrangements that can be understood either in terms of endogenous features or in terms of the “match” between institutional attributes and characteristics of the biophysical or social systems they regulate or manage. Analyzing an institution in isolation is a simplification that enhances analytic tractability and thus can help us identify its principal components and grasp its functional “logic” more easily than if we had to deal with complex external interdependencies. Sometimes it makes sense to argue that little is lost by adopting this acontextual approach. Even though no institution operates in a vacuum, some can probably be understood reasonably well without examining their relationships to other institutions. Yet it is becoming increasingly clear that this perspective has serious limitations in today’s world. The effectiveness and robustness of a specific institution will often depend not only on its own features but also on its relationship to and interactions with one or more other institutions. This is particularly obvious in an area such as environmental policy. Environmental damage typically occurs as a side-effect of other, perfectly legitimate activities, such as the production or consumption of goods and the transportation of people or goods. By implication, institutions designed to regulate these economic activities will have important ramifications for the environment as well. The other side of the coin is that policies or institutions designed to protect the environment cannot simply be added to other policies or institutions. In order to be effective, they must penetrate the activities that cause damage to the environment in the first place, and “their” institutional superstructure as well. Clearly, an analysis of the institutional dimensions of IHDP Institutions July 25, 2016 36 global environmental change cannot be confined to the subset of institutions that are specifically designated for the purpose of environmental management. Moreover, actors may decide deliberately to construct links between institutions that are not substantively (inter)dependent. One reason for coupling institutions may be that managerial efficiency can be enhanced by assigning responsibility for different rule systems or regimes to one rather than multiple organizations. Such “economy of scale” considerations are particularly relevant where “regime density” is high. Second, actors will sometimes see one institution as a model for the design of others.8 Emulation seems most likely in cases characterized by a combination of (a) high problem similarity and (b) marked differences in (perceived) institutional effectiveness or robustness and/or in the social status of the creators or leaders of the institutions concerned. Similarity is a basis for simple learning (“copying”), and institutions and actors believed to be “successful” are more likely to be emulated than those that are seen as “failures.” In an historical perspective, we can often identify more or less distinct “generations” of institutions, each of which is characterized by certain recurring features that can best be understood in terms of the diffusion of ideas or simply as instances of copying. Additionally, policy games may generate their own linkages. For various reasons of political expediency, actors may try to couple functionally unconnected institutions in some kind of package-deal (which means, in essence, that each side obtains something it strongly wants by conceding a 8. Although flattering, it is not always advantageous to be treated as a model. In some cases, a solution that could easily win acceptance when considered on its own merits in a particular case will be rejected because one or more of the key players fear that it will create a precedent for the design of other arrangements in the future. IHDP Institutions July 25, 2016 37 less highly valued item to the other). Sometimes one or more actors may see two or more institutions as components of a larger project. For example, even if it would be hard to argue that the regime established to prevent the depletion of stratospheric ozone and the regime regulating the use of deep seabed minerals are linked in a relationship of direct functional interdependence, an actor might see both as components of a new international economic order and thus demand "consistency" in terms of certain overarching principles of fairness or equity. Institutions that are subject to such politically constructed linkages cannot be understood fully unless we see them in their wider, socially constructed context. Attempts at changing an existing institution without due attention to such political linkages can lead into a morass of unexpected difficulties. As the preceding paragraphs imply, the problem of institutional interplay can be visualized in terms of a two-dimensional figure (see Figure 2). One dimension is that of substantive or functional (inter)dependence. Functional links exist whenever the establishment or operation of one institution directly affects the effectiveness or robustness of another, through some kind of inescapable interconnectedness. In the area of environmental _______________________ Figure 2 about here _______________________ change, this is clearly the case whenever the systems constituting the domains of different institutions are linked through biophysical (inter)dependency (e.g. through interaction among polluting substances or among different species within a larger ecosystem) or through the generation of consequences for human welfare and well-being by one sphere of social activity upon another (e.g. industrial production upon recreation). Functional linkages between institutions typically reflect (inter)dependence relationships existing in the IHDP Institutions July 25, 2016 38 biophysical contexts or social settings. In turn, institutional arrangements can affect the strength and scope of interdependence in the social setting; just think of the impact of the liberalization of international trade and investment on the increase in volume and importance of economic transactions. The other dimension is that of politically constructed linkages. Political linkages exist whenever actors decide to consider two or more institutions as parts of a larger complex or package. While functional linkages are inescapable facts of life, political linkages are deliberately constructed and “de-coupled.” Such linkages are most often studied in the context of bargaining about the formation or restructuring of institutions (Sebenius 1983), but we suggest that they can significantly affect the subsequent operations of institutions as well. In some cases, this coupling will take the form of unilateral adaptation of one institution to another. At the practical level, the question then becomes how to design or operate a particular institution given the existence of another. At the international level, a set of basic rights and rules defining state sovereignty are usually taken as an exogenously determined parameter for the design of issue-specific regimes. Even though the former may be seen as an obstacle to the effectiveness of the latter, issue-specific regimes are typically “embedded” in a suite of normative principles which constitute the deep structure of the international political system (Young 1996). In other cases political linkages take the form of mutual adjustment. This happens when two or more institutions are designed to work together in order to optimize joint effectiveness, muster political support, or achieve some other purpose that neither can accomplish on its own. Mutual adjustment requires the existence of a decision-making arena that can deal with both (all) institutions involved. Accordingly, it occurs more often “horizontally” (i.e. at a given level of social organization) than “vertically.” IHDP Institutions July 25, 2016 39 Functional (inter)dependence can be a sufficient reason for forging political linkages, but it is not a necessary condition. As pointed out above, institutions may be coupled for reasons of managerial efficiency or political expedience also when there is no (compelling) functional rationale for doing so. “Regime density” can itself be a strong argument for “clustering” (Young 1996). At least at any given level of social organization, the overall pattern is, though, likely to be one of positive - albeit imperfect - covariance between functional interdependence and political linkages (i.e. a clustering along the 45o line from the origin of Figure 2). Major incongruities (located in the areas labeled 1 and 4 in Figure 2) give rise to a set of interesting questions to which we will return in a subsequent section. Along both of these dimensions, we may distinguish between vertical and horizontal links. A vertical link is one that crosses levels of social organization (micro, meso, macro). (Inter)dependence relationships linking institutions at different levels are well known in social science. To give just one example: one of the main propositions of dependency theory is that the rules and structure of “the world capitalist system” determine a set of constraints and (perverse) opportunities that profoundly affect economic and social development at the micro-level (e.g. in rural communities in the third world). The accumulation of wealth in the social center and the aggravation of poverty and misery in the periphery are seen as inextricably linked through the allocation mechanisms of capitalism. Research exploring possibilities of introducing “alternative” and more environmentally benign lifestyles in local communities points to similar kinds of macro-level constraints. The debate within segments of the environmental movement is in this respect reminiscent of a debate that took place earlier in this century within the socialist movement about the feasibility of establishing “socialism in one country;” IHDP Institutions July 25, 2016 40 they both struggle with the question of “systemic forcing.” Looking at vertical links in a “top-down” perspective, we note that it is a well-known observation that many regimes require a certain minimum of institutional capacity at lower levels to be successfully implemented. Several studies, including those of Chayes and Chayes (1995) and Weiss and Jacobson (forthcoming), suggest that the problem of non-compliance with international environmental agreements may be as much a question of inadequate domestic capacity for implementation as one of deliberate defection motivated by the pursuit of free-rider benefits. Horizontal links are ties between institutions operating at the same level of social organization (e.g. that of the state). In the context of environmental change, the most important horizontal links are those between institutions regulating human activities causing environmental damage - primarily economic activities such as production and consumption of goods, transportation services, and so forth - and institutions established to protect environmental values. Also, within each of these categories a number of horizontal links can be found. Thus, an international regime designed to regulate marine pollution may have significant ramifications for disposal of polluting substances on land; any comprehensive approach to coping with marine pollution would have to include land-based sources as well. In a program dealing with human dimensions of global environmental change, it seems reasonable to give priority to functional links and to the relationship (in particular, the degree of congruity) between functional and political links. Both horizontal and vertical links are relevant to the study of institutional effectiveness and robustness, and we see no point in ranking them in some order of priority at this stage. We might point out, though, that one of the distinct contributions that an international program like IHDP can IHDP Institutions July 25, 2016 41 make is to help foster a genuinely global perspective on environmental problems. Improving our understanding of how macro-, meso- and microlevel institutions interact to shape human behavior and the outcomes of social processes - i.e. vertical links - is one integral and important part of that mandate. The research focus as delineated above calls for an interdisciplinary effort involving three main steps. First, we have to determine the scope and strength of functional links. This is by no means a trivial task. As pointed out above, functional links in the institutional “superstructure” to a large extent reflect (inter)dependence relations among the biophysical or social systems that constitute the domains of different institutions. We can safely assume that only a small subset of all these links are (yet) known and properly understood. As new knowledge is acquired, new and more complex relationships will emerge. Our understanding of the global climate change problem is a good illustration. As scientists improve their understanding of atmospheric chemistry, they discover - or at least become able to describe with greater accuracy and confidence - previously unknown but important interaction effects among different gases and between sources and sinks, leading to adjustments in the “greenhouse equation” and over time making it increasingly complex as well. The same kind of development is occurring in other areas, such as that of marine biology. As scientists have painted an increasingly complex picture of marine ecosystems, new and more complex models for multi-species or ecosystem management have been introduced to "match" our new understanding of nature itself. To complicate things further, functional links are not constants that can be determined once and for all; they are themselves subject to change as a function of, inter alia, changes in the “human load.” As the world population grows and the average individual (at least in the industrialized countries) uses more natural resources and other IHDP Institutions July 25, 2016 42 environmental goods, the aggregate impact of humankind’s activities on the global environment tends to increase. We do not have to be inbred pessimists to surmise that the combined effect of growth in knowledge and increasing impact of human activities on the Earth's biophysical systems will (continue to) outpace the development of institutional capacity for integrated governance. Having mapped functional links across substantive domains, the next task is to determine the consequences of these links - if any - for the effectiveness and robustness of the institutions concerned. To begin with, let us point out that only a small subset of the multitude of (inter)dependence relationships that exist within or among biophysical systems or systems of human activities are consequential in the sense that they significantly enhance or impair the effectiveness or robustness of the institutions involved. But some do, and in dealing with those a useful first step may simply be to try to distinguish links that are positive (in the sense that some kind of synergy between institutions is generated) from those that are essentially neutral and those that are negative (meaning that one institution impairs the effectiveness or enhances the vulnerability of another). Positive synergy is generated when, for example, the establishment or growth of an international regime or organization helps empower corresponding institutions at the national or subnational level, or vice versa. Such processes of (mutual) empowerment can occur without explicit coordination; they seem to have been an important factor in the development of institutions in the area of environmental protection. Other functional links are clearly negative. One example that comes to mind is the impact of the liberalization of the rules regulating international trade and financial flows on the capacity of national governments to manage domestic economies. Regimes for trade and investment may undermine the effectiveness of environmental regimes, and IHDP Institutions July 25, 2016 43 vice versa (the latter e.g. through providing a legal basis for introducing new non-tariff barriers or other obstacles to trade). Finally, institutions are sometimes linked in an exchange of “externalities” that may call for some (mutual) adjustment but by and large neither enhance nor impair institutional effectiveness. These would be benign games of coordination, where institutions would - in the terminology of Keohane and Nye (1977) - be “sensitive” but not “vulnerable” to each other. One example could be the relationship between environmental legislation and agencies on the one hand and national legal and law enforcement systems on the other. Environmental legislation will have to be adapted to the latter. Even though requirements of consistency sometimes may be seen as a constraint and at other times come as a welcome source of support, the net effect is likely to be close to neutral. The research challenge before us regarding the problem of interplay can now be summarized in three main points. We should seek to enhance our ability to (a) distinguish positive from negative and neutral "interference," (b) determine the significance of various kinds of interplay for the effectiveness and robustness of the institutions concerned, and (c) understand the dynamics of inadvertent as well as deliberate links between different (kinds of) institutions. In pursuing these questions we can treat effectiveness and robustness as twin concepts only to a certain point. Even though the two are to some extent related causally, they are not always affected to the same degree and through the same mechanisms. There are sound reasons to believe, for example, that the effectiveness of an institution by and large tends to be more sensitive - in both a positive and a negative sense - to functional linkages than robustness. On the other hand, it seems likely that at least certain aspects of robustness - particularly that of general legitimacy - can be IHDP Institutions July 25, 2016 44 highly sensitive to some kinds of political linkages. As we study the consequences of interplay for institutional effectiveness and robustness in greater depth, we will certainly acquire not only a sharper but also a more differentiated picture than we have been able to provide in this short overview. Knowledge in all these areas becomes particularly important when we move on to the third step: deriving policy implications for the design and operation of institutions. Particularly when we try to be specific, we will soon discover that policy implications to a large extent depend on the scope, strength, and character of the interdependence relationships existing within a system of institutions. At the most general level, we can say that an integrated or holistic response to global environmental change can be defined as one where: (a) all significant consequences of response decisions are recognized as decision premises, (b) alternative options are evaluated on the basis of some comprehensive and aggregate measure of utility or value, and {c} the different elements are consistent with one another (see Underdal 1980). In other words, a response strategy is "integrated" to the extent that it recognizes its own consequences as premises for decisions, evaluates them in terms of an aggregate measure of "global welfare," and penetrates all institutions and actors involved in (or indirectly relevant to) its implementation. These are obviously somewhat utopian ideals. Let us therefore here focus attention on just one structural aspect of this abstract ideal: the congruity or "fit" between an institution and the biophysical an social systems which make up its domain. IHDP Institutions July 25, 2016 45 5.3 The Problem of Fit Whereas the problems of scale and interplay encompass a range of comparatively specific ideas, the problem of fit revolves around one big idea. It asserts that the effectiveness and the robustness of social institutions are functions of the fit between the institutions themselves and the biophysical and social domains in which they operate. The better the match between an institution and its domain, the more effective and robust the institution will be. It is clear from this proposition that fit is a variable that can range widely from one situation to another and even from one time period to another with respect to the same institution. But beyond this conceptualization of fit as a variable, there are a number of ambiguities about the idea of fit that will require careful consideration in any effort to devise a fruitful research program dealing with this theme. Not only is it hard to establish the bounds of fit treated as a variable, but it is also and more importantly unclear how to organize our thinking about the concept of domain in this context. In our judgment, there are at least three differentiable components of domain that merit attention in developing this line of enquiry: (1) the biophysical context, (2) the social or societal setting, and (3) the problem structure or nature of the problem to be solved. In the discussion to follow, we consider each of these components with particular reference to issues relevant to global environmental change. Biophysical context. At one level, the significance of the fit between an institution and the biophysical systems with which it interacts is a straightforward matter that is easy to grasp. A few simple examples will suffice to illustrate this observation. Regimes concerned with the conservation of living resources that do not cover the entire ranges of migratory species (e.g. fish, marine mammals, birds) have built-in weaknesses that can subvert IHDP Institutions July 25, 2016 46 their ability to fulfill their goals. Conservation regimes that regulate the harvesting of specific species (e.g. the regime for whales and whaling) or trade in living resources (e.g. CITES) but that do not contain adequate provisions for protecting habitats that are critical to the survival of the relevant species cannot provide any guarantee that the resources in question will be conserved, no matter how effective they are in controlling harvesting or trade. Regimes governing the extraction of nonrenewable resources (e.g. hardrock minerals) that fail to provide clearcut rules dealing with the treatment of wastes are likely to precipitate largescale changes in surrounding ecosystems. Regimes that cover the extraction of oil and gas but do not deal with issues relating to the shipment of these resources to markets are apt to jeopardize terrestrial systems located along pipeline routes or marine systems located along tanker routes. Nor are these concerns limited to the operation of regimes dealing with environmental or resource issues in any narrow sense of those terms. Arms control arrangements, for instance, need to be sensitive to matters that involve the biophysical setting. A comprehensive nuclear test ban that failed to come to terms with physical conditions affecting efforts to monitor the occurrence of underground explosions would have little chance of success. Somewhat similar comments are in order regarding arrangements dealing with economic matters. A regime that regulates commercial fishing but fails to regulate the competition among fishers to acquire ever more advanced harvesting technologies, for instance, will lead to outcomes that are highly inefficient from an economic point of view. Such a regime is likely to produce poor results in terms of robustness as well. At the same time, there are several larger concerns that arise in thinking about the issue of the biophysical context within which regimes IHDP Institutions July 25, 2016 47 operate but that are less straightforward. This is partly a result of adopting a systems perspective in thinking about the biophysical context. Increasingly, we are aware that social institutions interact with biological and physical systems that are large, complex and interdependent rather than with separable components of these systems (e.g. individual species of fish) that can be managed in isolation from the more extended systems to which they belong (Sherman 1992). It is impossible to remove a sizable proportion of the biomass of one or a few species from an ecosystem, for example, without triggering cascades that affect - sometimes dramatically - the dynamics of the whole system (National Research Council 1996). Similarly, injecting wastes (e.g. chemicals like carbon dioxide or sulfur dioxide) into large aquatic, terrestrial, or atmospheric systems can trigger effects leading to profound changes in the overall systems. This realization has given rise over the last several decades to the growth of interest in whole ecosystems perspectives, critical loads, and the dynamics of bioregions. Intellectually, this development has much to recommend it. Yet it also poses problems in thinking about the fit between institutions and the biophysical context. Linkages extend in all directions both spatially and temporally, and there is no simple procedure for specifying appropriate system boundaries for purposes of dealing with management concerns in particular cases. Equally important, large biophysical systems are highly complex, often giving rise to non-linear processes that are poorly understood and impossible to predict. Whereas a focus on individual species tends to produce models (e.g. sustainable yield models) that are analytically tractable but of limited use for management purposes, then, approaches dealing with large biophysical systems in more holistic terms frequently yield models that are more relevant but less tractable analytically (Haeuber 1996). IHDP Institutions July 25, 2016 48 Systems thinking suggests the value of an approach that features efforts to identify properties of biophysical systems and then to match them with parallel attributes of institutional arrangements in the interests of developing social practices likely to produce results that are sustainable (Cleveland et. al. 1996, Costanza and Folke 1996). Just as we speak of attributes like flexibility, adaptiveness, and robustness in thinking about regimes, we can consider properties like diversity, productivity, fragility, and regenerative capacity in examining biophysical systems. Fit then becomes a matter of structuring institutions in ways that are compatible with the properties of the biophysical systems with which they interact. It makes sense, for example, to institute particularly strict regulations governing the harvest of living resources that belong to systems whose biological productivity is low. In the same way, there are good reasons to exercise particular care in dealing with systems in which discontinuities or nonlinear changes - in contrast to the restoration of some preexisting state - are high probability events (Wilson et. al. 1994). Much of the concern expressed by those endeavoring to strengthen the climate regime, for instance, can be traced to a judgment that the planet's climate system is subject to dramatic transitions of this sort. Going a step further, there is much to be gained from a strategy that seeks to endogenize the role of human actors in large biophysical systems in which humans have become major players (Netting 1981). Instead of seeking to understand the biological and physical dynamics of large marine ecosystems, for instance, and then turning to the activities of humans as something that is exogenous in the sense of occurring outside the system, this approach suggests integrating human actions both as forcing functions and as response mechanisms directly into models of these ecosystems. This way of thinking leads to the framing of a variety of searching questions that may IHDP Institutions July 25, 2016 49 have far-reaching implications for the design and administration of institutional arrangements. In looking at the fisheries of the Northwest Atlantic, to take a concrete case, we need to devote more energy to understanding the relative importance of changes in water temperatures, interactions among non-human species, human harvesting, and the introduction of anthropogenic pollutants as drivers in this large marine ecosystem (McAllister 1994). Improved knowledge of such matters would not only yield information directly relevant to setting harvest levels for individual species on an annual basis, but it would also help to determine what actions aside from the regulation of harvests are needed to sustain both the biophysical and the human systems in question. More generally, analysis of this sort would help to supplant current tendencies both to overestimate and to underestimate the role of anthropogenic forces in large biophysical systems. Social setting. Of equal importance is the fit between the character of an institutional arrangement and the social or societal setting in which it operates. A regime that requires the use of sophisticated technologies to ensure that the behavior of actors is transparent cannot succeed in a setting where these technologies are unavailable to many regime members. An arrangement that calls for complex and expensive management efforts on the part of members will run into trouble in situations where many members have little capacity to engage in such efforts. Institutions that require actors to develop and implement the use of new products (e.g. substitutes for CFCs in refrigerators and air conditioners) will need to address explicitly economic and financial issues relating to the transition from existing modes of production to alternative modes of production (Parson and Greene 1995). Arrangements that depend on the existence of a sense of community to ensure that the behavior of individual members is transparent and to bring pressure IHDP Institutions July 25, 2016 50 to bear on public officials to take seriously their institutional commitments are likely to run into trouble in settings that do not feature a strong civil society. For purposes of analysis, it is helpful to divide these observations about the social setting into two groups: those that pertain to the actors whose behavior is at stake and those that relate to the social system as a whole. In the first instance, there is the question of whether all the important actors (e.g. user groups in connection with living resources) are included as members of a regime. Arrangements dealing with whaling that do not include Japan, with climate change that do not cover China, or with biological diversity that do not encompass Brazil, for instance, are doomed to failure from the outset. Other concerns arise in connection with both the number of actors involved and the degree to which they form a homogeneous group in relevant ways (Keohane and Ostrom eds. 1995). It is one thing to regulate the activities of a handful of large corporations that produce CFCs, quite another to deal with thousands of smallscale fishers or millions of owners of automobiles. Similarly, what works among a group of industrialized democracies sharing a high standard of living and possessing the capacity to implement rules effectively may be quite ineffectual among groups of actors that are more heterogeneous with regard to economic and political structures as well as level of development. Even more specifically, a number of analysts have noted important differences among broadly similar countries, like Canada, Germany, the United Kingdom, and the United States, that have a bearing on the likelihood that specific institutions will operate successfully (Vogel 1986). In short, the societal setting matters, and successful institutions are likely to be those that are well-adapted to the social conditions under which they operate. Similar observations are in order about the nature of prevailing social systems in contrast to the character of the players who populate these IHDP Institutions July 25, 2016 51 systems. Social systems vary among themselves along a number of relevant dimensions, including the nature of the technologies in common use, the distribution of the material bases of power, the degree of homogeneity with respect to forms of economic and political organization, the extent of role differentiation among members, the strength of civil society, and the presence of what is often described as a sense of community. All these attributes may have significant implications for the types of institutions that are likely to work well in a particular societal setting. Arrangements requiring highly sophisticated monitoring systems cannot succeed if the relevant technologies do not exist or are tightly controlled by a few members of the group. The development and diffusion of new technologies over the last several decades, for example, has opened up a number of interesting possibilities for arms control regimes that were unworkable at an earlier time. The distribution of the material bases of power, by contrast, is a variable that has proven more controversial among analysts of social institutions. Some see the presence of a dominant actor or at least an issue-area hegemon that is willing to exercise strong leadership in the operation of an institution as an important determinant of success. Others are more inclined to look toward a wider distribution of power or the presence of some sort of balance of power as a condition for success. Clearly, much work remains to be done regarding the fit between social institutions and these material conditions prevailing in the relevant social systems. Recently, students of institutions have begun to take a more systematic interest in a number of more intangible attributes of the social setting within which institutions operate. One focus of attention in this regard is the idea of civil society (Lipschutz 1996). Although many of those who work on institutions have adopted a top-down approach emphasizing the roles of authoritative political and legal processes, there is growing interest in bottom- IHDP Institutions July 25, 2016 52 up approaches that point to the roles played by networks of nonstate actors in monitoring the performance of institutions and in bringing pressure to bear on various public authorities to live up to their formal commitments under the terms of institutional arrangements. The fit between social institutions and some measurable attributes of civil society could well emerge as an important focus of analysis in this field in the future. Going a step further in thinking about intangible conditions, the issue of community comes into focus. As our earlier discussion of the problem of scale suggests, there is growing interest in the role of community as a determinant of institutional effectiveness and robustness. Turning to the question of fit, the issue becomes one of assessing the degree to which the sense of community existing in a social setting is wellsuited to the character of the institutions devised to deal with problems arising in that setting. Analyzing questions of this sort poses a variety of tough methodological problems for those committed to rigorous empirical analysis. Nonetheless, evidence from a number of different levels of social organization suggests that the issue of fit between the attributes of institutions and the nature of the underlying community is one that we cannot afford to pass over lightly. Problem structure. Most analysts accept the proposition that institutions normally arise to deal with societal problems. But not all problems are alike, a fact that raises important questions about the fit between the institutions created to solve problems and the nature of the problems they address. A number of difficulties confront those seeking to think systematically about problem structure. Yet we are already able to say some interesting things about the fit between institutions and problem structure. To begin with, there is a useful distinction between general and specific approaches to thinking about problem structure. General approaches direct attention to matters like the locus of specific problems on a spectrum running IHDP Institutions July 25, 2016 53 from benign to malign problems and the extent to which the problem is best viewed as a question of conflict resolution or as a coordinated effort to pursue some common goal. The benign/malign distinction, as used in the work of a group of Norwegian analysts (Wettestad 1995) and in a large-scale comparative project on regime effectiveness led by Miles (Miles et. al. forthcoming), is conceptualized as a function of three factors: the degree of incongruity between individual and collective payoffs, the degree of asymmetry, and the extent to which conflict is cumulative rather than crosscutting. Others (Rittberger and Zuern 1991) have approached problem structure from the perspective of conflict analysis, adopting familiar distinctions like those between conflicts of interests and clashes of values and between goods valued in absolute and relative terms. A related approach directs attention to processes of problem solving and integrative bargaining (Walton and McKersie 1965). While it should be possible to translate from one of these conceptualizations to another, more work is needed to clarify and operationalize these distinctions; game-theoretic concepts may prove useful for this purpose. Despite these conceptual concerns, it is already easy to see that general distinctions regarding problem structure have an important bearing on the design of institutions; the nature of the institutions needed to solve problems will vary as a function of the fundamental character of the problems themselves. Whether or not these general approaches to problem structure prove fruitful, it is possible to identify a variety of more specific features of problems that have unambiguous implications for the nature of the institutions required to solve them. Work on the theory of games and related matters has proven particularly fruitful in thinking about such matters. There is no need to expend time and energy worrying about devising compliance mechanisms in the case of coordination problems, for example, whereas this is IHDP Institutions July 25, 2016 54 often a major concern in connection with collaboration problems (Snidal 1985). The number of actors whose behavior must be considered is a significant feature of problem structure because decisionmaking procedures that work well with only a few players break down when there are many; the role of coalitions grows as numbers of actors increase, and the pervasiveness of free riding regarding the costs of operating an institution increases as a function of the size of the relevant group (Oye ed. 1986). The degree to which an institution is expected to remain in operation over the long run is relevant because it affects the impact of the "veil of uncertainty" and the incentives of members to rely on some sense of fairness or justice as a means of inducing all or most of the members of the group to participate actively on an ongoing basis (Brennan and Buchanan 1985). The level of uncertainty regarding the nature of the problem itself (e.g. climate change versus ozone depletion) is significant because building in flexibility or procedures for adapting institutional arrangements looms larger as the level of uncertainty increases. It would be easy to amplify this set of illustrations. But the point is clear. Individual problems have many specific characteristics that have far-reaching implications for the nature of the institutional arrangements needed to solve them. The fit between institutions and problem structure emerges as a major concern in this connection, and there is much work to be done in developing a systematic understanding of this range of relationships at every level of social organization. As these comments suggest, studies of the problem of fit lend themselves to a consideration of design principles of immediate interest to those charged with creating and operating social institutions. It is possible to imagine the accumulation of a growing collection of more or less specific principles that practitioners can consult as the need arises. Some of these principles are relatively easy to formulate as the following examples make IHDP Institutions July 25, 2016 55 clear. Include the entire migratory range of living species. Be sure to include all the significant groups of users of the resources in question. Ensure that the technologies required to operate an institutional arrangement exist and are available to all participants on reasonable terms. Focus on compliance mechanisms in dealing with collaboration problems but do not spend time worrying about compliance in connection with coordination problems. Build in institutional flexibility in cases where there is a high level of uncertainty about the nature of the problem itself. Other principles are less obvious and require more subtle interpretations. It is important to devote increased attention to decisionmaking procedures as the size of the group increases, for instance, but this does not tell us exactly what to do about the issue. Similar comments are in order about matters like the distribution of power in the material sense or the relationship between group size and free riding. We must acknowledge as well some caveats about design principles emerging from the analysis of fit. It is not easy to reduce principles to operational rules of thumb; many important nuances are lost in the course of this transition. There are many cases where the range of applicability of principles will be hard to determine. It is useful to differentiate between coordination problems and collaboration problems, for instance, but situations frequently arise in which the classification of a particular problem in these terms is itself a contentious issue. In other cases, there is the prospect of the emergence of competing design principles. Differing views regarding the importance of finding a dominant actor willing to accept a leadership role exemplify this prospect. In many cases, we do not know enough yet to formulate relevant design principles. Much work remains to be done on the concept of problem structure, for example, before this intuitively appealing idea can be incorporated in any systematic fashion into useful design principles. None of these observations should be regarded as discouraging. IHDP Institutions July 25, 2016 56 On the contrary, we are already in a position to articulate some useful design principles, and there are clear indications that further research on the fit between institutions and the domains in which they operate will prove fruitful not only in adding to our general knowledge of social institutions but also in framing additional design principles of value to practitioners. 6. Links to IHDP Substantive Themes What is the connection between the analytic problems of scale, interplay, and fit and the substantive problems that loom large on the overall global change agenda and more particularly the IHDP research agenda? Specifically, what are the institutional dimensions of the themes associated with the established core project on Land-Use and Land-Cover Change (LUCC) and with the emerging core project on Industrial Transformation (IT)? We cannot address these questions exhaustively at this stage. But they constitute central concerns in the development of a core project on the crosscutting theme of the Institutional Dimensions of Global Change (IDGC), and we offer some preliminary observations about linkages between institutional dimensions and the substantive concerns of LUCC and IT in this section. A more focused treatment of these issues will constitute an important component of the Science Plan for the IDGC core project to be developed in the near future in consultation with a cross-section of scientists working on the central concerns of LUCC and IT as well as on institutional issues. IHDP Institutions July 25, 2016 57 6.1 Institutional Dimensions of LUCC It is easy to identify a range of social drivers that shape patterns of land use prevailing in specific places at particular times (IGBP/HDP 1995). Some observers point to cognitive or cultural forces, like the differences between indigenous beliefs about human beings belonging to the land and European or western concepts of land ownership, in accounting for variations in stewardship or efforts to care for the land as an end in itself (Cronon 1983). Others emphasize material conditions, like the size and distribution of human settlements or the availability of various technologies, in explaining changes in patterns of land use over time. But there is no doubt that institutional factors play a large role in shaping both the behavior of humans as users of land and associated natural resources and human responses to changes in land cover. Among the most well-developed arguments pointing to institutional determinants of patterns of land use are those that center on the consequences of different structures of property or use rights. To illustrate the linkages between institutions and patterns of land use, therefore, we comment in this section on several well-known debates about the roles of common property, public property, and private property in shaping patterns of land use at various levels of social organization. In each case, we argue, the links are strong but considerably more complex than the most familiar propositions about such matters would lead one to believe. The study of these linkages also raises numerous questions about what we have termed the problems of scale, interplay, and fit. Many observers have argued that common property arrangements generate patterns of land use leading to the depletion of renewable resources and the pollution of ecosystems. Well-known today in terms of the image of IHDP Institutions July 25, 2016 58 the tragedy of the commons, the logic associated with this argument is simple (Hardin and Baden eds. 1977). It suggests that users of common property resources will overuse these resources because they have little or no incentive to conserve them for future use or to invest in activities designed to protect or upgrade these resources over time. Individual appropriators will assume that any resources they leave will simply be harvested by other members of the user group and that others will benefit from their conservation efforts without contributing to the cost of implementing them. If each member of the group responds in a similar fashion, the result will be the familiar tragedy in which stocks of wildlife are depleted, common fields are exhausted, and ecosystems degraded. As it turns out, however, there are many instances in which common property arrangements do not lead to the tragedy of the commons (Feeny et. al. 1990). Sometimes this is simply a consequence of supply exceeding demand, a situation in which users can behave individualistically without causing collective harm. But in many cases, the failure of the tragedy of the commons to materialize is attributable to the development or more or less elaborate sets of rules or institutional arrangements that place effective restrictions on the behavior of individual users of common property resources. Spearheaded by students of smallscale traditional societies located in various parts of the world, a vigorous intellectual movement has emerged that focuses attention squarely on the role of institutional arrangements as devices for controlling the dynamic associated with the tragedy of the commons. The point of this line of thinking is not to assert that users of common property never deplete resources or pollute ecosystems. Rather, the resultant work seeks to pinpoint those conditions that determine whether owners of common property resources succeed in using their resources in a sustainable fashion and whether these conditions are more or less restrictive IHDP Institutions July 25, 2016 59 than the parallel conditions governing sustainable uses of public or private property (McKean 1992). Recently, students of international relations have posed similar questions about the use of common property resources that lie outside the jurisdiction of the members of international society (e.g. the high seas, the electromagnetic spectrum, the global climate system). This has opened up interesting opportunities to consider matters of scale in thinking about the use of common property resources (Young 1994b). It has also introduced a lively debate about the idea of "governance without government," since both smallscale societies and international society are settings in which users of land and natural resources have devised techniques for solving problems of governance without resorting to the establishment of governments in the ordinary sense of the term (Rosenau and Czempiel eds. 1992). The effect of this analytic development has been to revive interest in common property at all levels of social organization as an alternative to both public property and private property among those interested in controlling patterns of land use to avoid detrimental environmental consequences. In contrast to the conditions prevailing in smallscale societies and in international society, public property is a prominent feature of most national or domestic social systems. Even in the United States, where the value of private property is deeply engrained in the prevailing political culture, the federal government alone holds title to about one third of the nation's land (Brubaker ed. 1984). Comparable figures in many other countries are substantially higher. In some cases, the size of the public domain is a product of historical accidents, and governments have actively pursued policies designed to transfer publicly owned land into private hands. In other cases, the dominance of the state as a land owner is a product of political ideology. IHDP Institutions July 25, 2016 60 But in either case, the importance of the public domain in most national societies makes it interesting to note that public property has become a common target of criticism on the part of those concerned with the environmental consequences of patterns of land use (Stroup and Baden 1983). Public land, on this account, is apt to be exploited by special interests (e.g. railroads, timber companies, miners) capable of manipulating the political process to their own advantage but lacking any incentive to protect ecosystems that cannot be used to produce short-term private gains. In some cases, these interests have orchestrated the transfer of public land into private hands on concessional terms. In other cases, private interests have been content to exploit the natural resources of the public domain without taking title to such lands or assuming any responsibility for environmental stewardship. Added to this set of problems are recurrent conflicts over the control of the public domain between different levels of government in national societies. The ongoing controversy between the U.S. federal government and the governments of a number of western states regarding the control of public land, often described as the "sagebrush rebellion," is a prominent case in point (Nelson 1995). Yet here, too, reality is more complex than this simple logic suggests. National governments have developed strikingly different approaches to the management of the public domain, even within the same society and during the same era. In the United States, for example, the federal government operates, at one and the same time, distinct systems allowing miners to patent claims to land containing commercially valuable minerals, ranchers to lease public grazing lands, timber companies to purchase wood on land located in the public domain, and fishers to harvest fish in publicly managed waters in the absence of any payment to the government (Klyza 1994, Wilkinson 1992). At the same time, governments have played a critical role in framing policies IHDP Institutions July 25, 2016 61 to set aside portions of the public domain to be managed as parks and wildlife refuges, and they have pioneered in the development of the concept of wilderness as a long-term management philosophy for large tracts of publicly owned land (Nash 1982). Without doubt, the management of the public domain is subject to recurrent controversy and is affected by passing fashions regarding human/environment relationships. Nonetheless, there is no denying that the existence of the public domain has provided opportunities to experiment with various forms of environmental stewardship that would have been unlikely to emerge in connection with other structures of property rights. Another well-known argument focuses on the virtues of private property as a means of avoiding the alleged excesses of common property and public property systems. Here again the central idea is simple. It focuses on the proposition that owners of private property experience unambiguous incentives to conserve or even enhance the value of their holdings and therefore to use land on a sustainable basis (Anderson ed. 1983). Unlike the individual member of the ownership group in the case of common property, the owner of private property can reap future benefits from the resources he sets aside today. And unlike the user of public property who has no incentive to think in terms of stewardship, the holder of private property will seek to maximize the income stream flowing from his property over time. It is not difficult to point to evidence that supports this argument. Ranchers typically treat the land they own differently from land they lease from the government. Timber companies follow different practices in dealing with national forest land and privately owned commercial forests. Manufacturers use aquatic and marine systems as sinks for wastes in ways that differ from the way they use private property whose owners charge for such services. IHDP Institutions July 25, 2016 62 Yet, as many critics have noted, the virtues of private property systems are by no means unambiguous when it comes to their consequences for patterns of land use (Brubaker ed. 1984). Private owners generally pay little attention to uses of land, like the maintenance of biological diversity, that take the form of public goods whose benefits cannot be subjected to exclusionary devices. Private owners often employ high discount rates in making decisions about the use of their land. In extreme cases, they may find it attractive to extract whatever profits they can in the short run and then simply abandon the land as they move on to other pursuits. Nor are private owners immune from the impacts of ignorance or misinformation affecting patterns of land use. Agricultural practices leading to severe losses of topsoil, for example, often reflect a poor understanding of the relevant ecosystems as well as a lack of concern for longer-term consequences. As a result, most societies have experimented with a variety of restrictions on the freedom of private owners to use their land as they see fit. Some of these restrictions have proven ineffective (e.g. many soil conservation regulations) or inefficient (e.g. many regulations dealing with the disposal of wastes). Others have produced a severe backlash on the part of property owners who oppose such restrictions as impermissible or "regulatory" takings on the part of government (Epstein 1985). Nonetheless, it is clear that private property, like common property and public property, is not a panacea when it comes to the environmental consequences of land use. These observations regarding structures of property rights should suffice to demonstrate the importance of institutional drivers as determinants of patterns of land use and the impacts on ecosystems associated with prevailing patterns of land use. At the same time, institutional arrangements figure prominently in many efforts to respond to changes in land cover, whether or not these changes are attributable to anthropogenic forces. IHDP Institutions July 25, 2016 63 Persistent decreases in precipitation may give rise to the development of rules regarding withdrawals of water from streams and practices designed to control the risk of fire. Changes in the abundance and distribution of species of wild fauna and flora can lead to public regulations regarding the freedom of property owners to make use of such species located on their land. Concerns about the fragmentation of habitats sometimes kindle efforts to regulate land use through various forms of zoning and, more recently, to work out swaps between private and public owners designed to protect critical habitats. Whether the land in question is subject to common property, public property, or private property arrangements, users can expect to find themselves subject to increasingly elaborate resource regimes that involve overlaying systems of rules restricting uses of land on the underlying substrate of property rights. Needless to say, the rules that make up these regimes differ dramatically across places, times, and levels of social organization. But the complete package of institutional determinants of land use in every case consists of a set of property or use rights coupled with a collection of restrictive rules that grow up over time to address social problems arising from the activities of land users. At one level, resource regimes treated as responses to problems associated with various uses of land may seem difficult to compare with one another. They vary across cultures, time periods, and levels of social organization. Yet they are all mechanisms of social control that come into existence in response to problems either caused by the unrestricted behavior of users of terrestrial and marine systems or caused by biogenic forces affecting uses of land on the part of humans (Young 1982). Given the fact that these regimes also vary greatly in terms of their effectiveness or, in other words, the degree to which they succeed in solving the problems that lead to their creation, the study of resource regimes offers excellent opportunities for comparative analyses by those concerned generally with matters of land use IHDP Institutions July 25, 2016 64 and more specifically with the problems of scale, interplay, and fit. Are there certain factors that are common to successful resource regimes regardless of the resources they address or the level of social organization at which they operate? Conversely, are resource regimes highly situation specific in the sense that success depends on tailoring the characteristics of these institutional arrangements with great care to the particular setting in which they are expected to operate? The answers to these questions will have farreaching implications for the efforts of those charged with controlling patterns of land use in the interests of coming to terms with largescale environmental change. Whatever their consequences in terms of conservation, resource regimes commonly produce distributive consequences that affect the interests of stakeholders or user groups concerned with the relevant resources or ecosystems. Regimes may establish preferences among subsistence, commercial, and recreational harvesters of living resources that take effect whenever the supply of the resources is insufficient to satisfy the aggregate demand. Regimes may lay down liability rules that govern situations in which the activities of one user group (e.g, those responsible for agricultural runoffs) interfere with the activities of another user group (e.g. harvesters of fish). Similarly, these arrangements may have the effect of subsidizing the activities of certain user groups (e.g. ranchers who pay fees to graze cattle on public lands or wood producers who harvest timber on public lands). Because the distributive impacts of regimes show up early and affect the private interests of various user groups, these consequences of institutional arrangements regularly become contentious issues in various public forums. It follows that any effort to establish regimes designed to protect the integrity of large ecosystems must be sensitive to distributive issues that can destroy the capacity of institutional arrangements to contribute to the pursuit of conservation. IHDP Institutions July 25, 2016 65 6.2 Institutional Dimensions of IT To ask about the determinants of industrial transformation is to launch an enquiry into the drivers of economic change approached from a systems perspective. As a recent IHDP Scoping Report on this emerging project puts it, "[i]ndustrial activities can be regarded as a system constituted in ways that vary through time and over space, and which have impacts on the natural environment that are also spatially and temporally variable." Industrial transformation, then, is a matter of the "human drives and mechanisms that could enable a transformation of the industrial system towards sustainability, and in physical terms to decouple industrial activities from their environmental impacts " (Vellinga 1996: 3-4).9 Numerous factors play a role as determinants of the overall character and performance of economic systems. Among these, institutional factors figure at (1) the macro-level through the operations of organizations like the WTO and the development of regimes dealing with matters such as intellectual property rights, (2) the meso-level through the efforts of governments to devise rules relating to economic behavior and the initiatives of a variety of nongovernmental organizations, and (3) the micro-level through changes in operating procedures at the level of the firm. Because the IT project is at an earlier stage of development than LUCC, it is not possible at this stage to lay out a detailed research agenda dealing with the institutional dimensions of industrial transformation. But the project is evolving rapidly and even at this early stage, we can identify important links between institutional forces and major changes in the character and performance of economic systems. Some specific examples will serve to clarify 9. We are indebted to Pier Vellinga for helpful comments on an earlier draft of this section of the report. IHDP Institutions July 25, 2016 66 this point. A central theme of the "new economic history," exemplified by the work of North and his collaborators (North and Thomas 1973), is the idea that the emergence of systems of private property rights played an essential role in the growth of towns and the rise of modern trading systems in Europe starting in the later middle ages. In effect, secure property rights available to ordinary individuals allowed tradesmen without significant land holdings to become entrepreneurs capable of bringing together diverse factors of production to fabricate manufactured goods and creating organized markets in which these goods could be bought and sold. The new economic historians have emphasized the role of these institutional innovations in explaining the rise of the West and with it the growing geopolitical dominance of Europe that reached its height during the nineteenth century. This is not to deny the significance of cultural factors, like the opposition of the Catholic Church to the establishment of money markets or the system of values and beliefs that Weber termed the Protestant ethic (Weber 1958). Nor is it to deemphasize the significance of technological advances, such as new agricultural practices allowing declining numbers of farm workers to feed growing human populations. But the new economic history points to the role of emerging systems of property rights even in connection with these factors as sources of incentives to create money markets or to invest time and energy in inventing and perfecting new technologies. While the technological advances of the eighteenth and nineteenth centuries obviously loom large as driving forces behind the industrial revolution, the rise of capitalist economies - free enterprise systems relying on market signals to govern decisions about the production of goods and services - owes a great deal to the emergence of a number of institutional innovations built on the foundation provided by private property but going well beyond issues of property rights as such. These innovations include IHDP Institutions July 25, 2016 67 increasingly elaborate practices dealing with contracts, financial transactions, torts, patents, and insurance as well as new forms of organization reflected in the growing role of corporations as instruments for the conduct of industrial production. Taken together, these institutional arrangements constitute a complex framework that is essential to the operation of market-based economies; their central roles make it easy to understand why many analysts approach economic systems as social institutions in which actors occupying well-defined roles (e.g. buyer and seller, producer and consumer) interact with one another on the basis of clearcut rules that play an important part in determining the collective outcomes flowing from the operation of these systems. Recently, a number of analysts have raised questions as well about interactions between economic systems and the political institutions with which they interact in specific social settings. One interesting line of enquiry in this area concerns links between capitalism and democracy on the one hand and between socialism and authoritarianism on the other. Although this subject is plagued with definitional pitfalls, it would be difficult to make a compelling case for the proposition that the presence of democratic political institutions constitutes a necessary condition for capitalism to arise and flourish. Conversely, there is no compelling reason to conclude that democratic socialism is an oxymoron, despite the evidence from some notorious twentieth century cases. Still, there are certainly connections of a more specific nature between the character and performance of economic systems and political institutions. Because capitalism requires an institutional environment featuring secure property rights, enforceable contracts, and welldefined liability rules, a political system allowing the state to expropriate private property at will and offering no assurances that contractual obligations will be fulfilled would constitute a major impediment to the IHDP Institutions July 25, 2016 68 operation of a capitalist economy. By the same token, although some arrangements associated with socialism (e.g. redistributive programs in the areas of health, education, and welfare) are perfectly compatible with democracy, the operation of a socialist economy requires a stable and authoritative planning process that is likely to be disrupted by too much exposure to erratic fluctuations in public opinion. These observations focus on the role of institutional drivers as determinants of the character, performance, and evolution of economic systems. But much of the interest in industrial transformation as a focus of attention in connection with largescale environmental change centers on the development of strategies designed to bring about changes in features of advanced industrial systems that are regarded as sources of anthropogenic disturbances in key ecosystems. What would it take, for example, to change industrial practices in such a way as to reduce their energy intensity or at least to decrease reliance on energy sources that are major producers of greenhouse gas emissions? What are the prospects for pursuing the ideas of the industrial ecology movement regarding industrial loops formed by using residuals from one manufacturing process as valuable inputs into other industrial processes (Ayres 1996)? How might we make progress toward the dematerialization of industrial production that many analysts have suggested as a means of controlling the ill effects of global environmental change? Here, too, the focus is on forces producing change in economic systems. But now the emphasis is on devising conscious strategies to avoid or control anthropogenic impacts on key ecosystems rather than identifying those forces that explain patterns of change in economic systems over time. As in the discussion of responses to land cover change, institutional factors come into play in many ideas about ways to encourage industrial IHDP Institutions July 25, 2016 69 transformation of an environmentally benign sort. Several distinct strategies involving institutional initiatives are worth noting even in this brief account. Many observers suggest redefining prevailing systems of property rights in such a way as to require firms to pay for environmental services (e.g. the use of atmospheric and aquatic systems as repositories for wastes). Some would go a step farther and compel firms to compensate victims of externalities associated with their operations (e.g. health effects associated with pollution or the degradation of property resulting from nearby industrial operations). An alternative approach features the development of systems of regulations that have the effect of placing restrictions on the rights of property owners, without redefining property rights in any direct sense. Much of the recent debate about efforts to alter economic behavior in the interests of protecting environmental values centers on arguments about the relative merits of institutional innovations intended to channel behavior through the manipulation of incentives (e.g. making polluters pay for the damages they cause) or through the formulation of rules governing the actions of economic actors (e.g. requirements that manufacturers outfit new cars with catalytic converters). This perspective also suggests the value of differentiating among levels of social organization in thinking about ways to promote industrial transformation. Understandably, much attention in this area has been directed toward initiatives that governments might take to influence the behavior of actors in industrial systems. Specific suggestions involve changing systems of national accounting to include costs associated with the use of natural capital or the pollution of ecosystems; reconfiguring property rights to internalize various costs of production that are currently ignored as externalities; introducing systems of standards and charges or tradable permits to give firms incentives to include environmental considerations in IHDP Institutions July 25, 2016 70 calculations of production costs; experimenting with eco-labeling in an effort to influence the behavior of consumers by making sure they are wellinformed about products, and instituting truth in advertising rules to publicize environmental concerns associated with various products. This line of thinking raises as well the now familiar debates about the relative merits of policies based on command-and-control approaches (e.g. the use of regulations or directives) and market-based approaches (e.g. the introduction of tradable emissions permits) as methods to redirect the behavior of actors in industrial systems. Important as public authorities are, debates about government actions should not be allowed to obscure the role of institutional factors at the level of industries or industrial sectors and even at the level of the individual firm in guiding behavior that is relevant to industrial transformation. Whereas individual firms might be willing to alter methods of production if they could be sure that their competitors would follow suit, it is often difficult to create regimes capable of ensuring that all participants in a given industry or economic sector will comply with important rules. Are there ways short of government intervention to solve this problem? Within the individual firm, by contrast, there are important issues relating to the development of environmental auditing procedures, appeals to environmental consciousness as a marketing tool, and the creation of units within corporations assigned to keep track of environmental concerns and to institutionalize environmental advocacy. Intersecting with these questions about the behavior of the firm are issues relating to the formation of consumer preferences, the impact of these preferences on corporate behavior, and the role of nongovernmental organizations in sensitizing consumers to environmental issues associated with specific products and production processes. Recent shifts in the allocation of tasks and resources between the public sector and the private IHDP Institutions July 25, 2016 71 sector in many societies make it particularly important to think more systematically about strategies to promote industrial transformation that do not rely on government action. From a theoretical perspective, much of this discussion about strategies designed to alter industrial systems can be viewed as a debate about the production of collective or public goods. The protection of the Earth's climate system and the maintenance of biological diversity, for example, are collective goods in the sense that there is no way at present to exclude those who do not contribute from benefiting from the production of these goods. Left to their own devices under conditions of this sort, individual actors can be expected to minimize their voluntary contributions to the supply of such goods or, in other words, to engage in what is often called free-riding behavior (Olson 1965). Here again the solution is likely to involve institutional innovations. In some cases, this may mean devising ways to transform collective goods into private goods through the introduction of exclusion mechanisms where none had previously existed (e.g. encoding TV broadcasts and requiring viewers to pay for the use of decoding devices). In other cases, the supply of collective goods is apt to require the intervention of some public authority able to devise appropriate cost-sharing mechanisms and to raise revenues needed to fund such arrangements. As students of public choice have noted, turning to political institutions as a means of supplying collective goods is far from trouble free, and it is not surprising that vigorous debates have arisen in many settings about the relative merits of alternative approaches to the supply of such goods. But the point we wish to stress in this account is that all the major options for coming to terms with environmental problems involving the supply of collective goods feature institutional innovations of one sort or another. IHDP Institutions July 25, 2016 72 7. Links to LOICZ The notion of a matrix agenda including joint modules at the interface between projects focusing on substantive problem areas and projects focusing on cross-cutting themes was originally adopted with reference to IHDP itself. There is, however, one IGBP core project that seems to offer an interesting potential for cross-fertilization with the project outlined here: the project called Land-Ocean Interactions in the Coastal Zone (LOICZ). As described in its Implementation Plan, the overall purpose of LOICZ is to determine at regional and global scales: the nature of that dynamic interaction [where land, ocean, and atmosphere meet]; how changes in various compartments of the Earth system are affecting coastal zones and altering their role in the global cycles; to assess how future changes in these areas will affect their use by people; and to provide a sound scientific basis for future integrated management of coastal areas on a sustainable basis. (IGBP 1994: 7) LOICZ focuses first and foremost on natural science topics such as the impact of changes in external forcing or boundary conditions on coastal fluxes, coastal biogeomorphology, and the effects of sea level change on coastal ecosystems. But one of the project's four main foci does deal explicitly with economic and social aspects, including the role of institutions. Among the institutional questions highlighted are the effects of different ownership and usufruct rights on human uses of coastal resources, and the effectiveness of different management or governance systems in providing "integrated management... on a sustainable basis." The former suggests the possibility of developing a joint module that parallels the one that we have suggested at the interface with LUCC. Developing such a parallel module could open interesting possibilities for creating additional synergy through trilateral exchanges. The latter question is germane to our interest in the ways in which institutional effectiveness is enhanced or impaired by (a) various kinds of IHDP Institutions July 25, 2016 73 links and interplay between two or more institutions, and (b) the degree of congruity or fit that exists between an institution and the biophysical or social systems that constitute its domain. This leads us to conclude that a joint module with LOICZ could focus on one or both of the following broad research questions: (1) How do different systems of property and use rights affect the nature, volume and distribution of human uses of coastal zone resources? (2) How effective are different management and governance systems in guiding human activities in the coastal zone so as to enhance social welfare on a sustainable basis and in responding to extreme events (such as hurricanes and tidal waves) and incremental changes (such as sea-level rise) in coastal environments? 8. Integration with Other Global Change Models An IHDP project on institutions could and should be part of a more comprehensive research agenda dealing with global environmental change. This implies, among other things, that research on institutions would be undertaken partly for the purpose of feeding into more comprehensive, interdisciplinary models of global environmental change. The matrix architecture that we have proposed above, which includes joint modules at the interface with other IHDP projects focusing on substantive problem areas, points directly to this function. Since interdisciplinary models require a certain minimum of compatibility among different components, it follows that an attempt at becoming part of such a comprehensive enterprise may have important implications regarding the choice of analytical tools as well as methodological approaches. Suffice it here to consider briefly three of the IHDP Institutions July 25, 2016 74 issues that typically arise at the interface between social and natural science research on global change. One of the distinctive features of most natural science components of global change models is that they require quantitative statements about the form and strength of causal relationships. The impact of variable X on variable Y is to be expressed in terms of at least interval scale measurement. This is a requirement that social science research often cannot meet (and one which sometimes creates great difficulties for the natural sciences, too). Most of the key variables we have referred to above - including those of institutional effectiveness and robustness - are normally measured only in terms of ordinal scales. Moreover, much of social science research on institutions is aimed at the more basic objective of simply identifying the causal mechanisms at work and understanding their operational “logic.” It is a far cry from understanding the basic workings of common property systems to determining precisely how much the intensity and distribution of human uses of a given environmental resource would be affected by a particular change in the property rights system. What social science research can presently deliver is essentially the former; what the builders and operators of comprehensive, interdisciplinary global change models ask for is primarily the latter. A second issue pertains to forecasting. The effort to predict future developments is an integral part of much natural science research on global change. At the same time, it is an exercise in which some social scientists simply refuse to become involved and to which many others would respond by at least insisting that there is a fundamental difference between forecasting the development of a biophysical system and forecasting human behavior. It IHDP Institutions July 25, 2016 75 is not yet clear to what extent and how this difference can be reflected adequately in comprehensive global change models. The third issue pertains to time scales. Natural science research often deals with time scales that social scientists simply cannot cover. Even the relatively “modest” ambitions of LUCC, which aims at mapping land-use and land-cover changes that have taken place over the past 300 years and forecasting changes that will take place over the next 50-100 years, go beyond what several relevant fields of social science research can confidently claim to cover adequately. For example, it would be hard to find good data allowing us to map with a fair amount of precision changes that have occurred in human perceptions and valuation of land and benefits derived from land use between the 17th and 20th centuries. We are probably in a somewhat better position to describe institutional changes. The general message is nonetheless clear: social science researchers most often find themselves at a disadvantage compared to their natural science counterparts when it comes to data needed to deal with long time scales. The same applies to some extent to large spatial scales. One important implication of this is that a project on the institutional dimensions of global environmental change should try to frame its findings in terms that can be considered “transdisciplinary” whenever such tools are available. In this connection, we think a strong case can be made for turning to the analytical toolbox of formal modeling generally and the “rational choice” paradigm more specifically as an overarching, integrating framework. We do recognize that much current research relevant to the agenda that we have outlined above is framed in terms of other and to some extent quite different analytical perspectives. This applies, inter alia, to much important work subsumed under the label of the “new institutionalism” (March and IHDP Institutions July 25, 2016 76 Olsen 1989). We think it is important to tap into these traditions of research. But at the same time, we regard the adoption of a coherent analytical framework as an important, perhaps even a necessary, step to ensure consistency and integration of an interdisciplinary and international project on the institutional dimensions of global change. In some form, rational choice modeling is used in all the social sciences, albeit more so in economics than in anthropology. It also provides, we believe, a language that is particularly well-suited for communication and collaboration with natural scientists. 9. Integrative Activities In one sense, the research program called for in this report is straightforward. We propose a concerted effort to (1) expand our knowledge of the effectiveness and the robustness of social institutions, (2) direct systematic attention to the problems of scale, interplay, and fit as keys to the pursuit of this objective, and (3) apply the resultant insights to the substantive problems involving largescale environmental change identified in the LUCC, IT, and LOICZ core projects. Yet there are several cross-cutting issues of a conceptual and methodological nature that arise in all efforts to study the impacts of social institutions and that are pertinent to a core project on the Institutional Dimensions of Global Change. In this section, we single out four issues for particular attention: the development of a common discourse, the achievement of conceptual harmonization, the creation of empirical databases, and the distillation of design principles. 9.1 Developing a Common Discourse The study of social institutions brings into contact several groups of researchers who do not have a tradition of interacting cooperatively and who, IHDP Institutions July 25, 2016 77 in many cases, define key terms differently or use different terms to refer to the same thing. Economists and sociologists, for instance, differ markedly in the use of such terms as institutions and organizations. Even more to the point is the relative lack of dialogue among those who study institutions at different levels of social organization. Recent efforts to initiate comparisons relating to institutional issues arising in smallscale, local societies and in international society make it clear both that there is much to be gained from such comparisons and that there is much to be learned about how to communicate effectively among members of the two research communities (Keohane and Ostrom eds. 1995). When we add the ideas of those who study the physical and biological systems with which social systems interact, the problem of communication increases significantly. Recent efforts to identify and compare concepts used to describe the principal attributes of biophysical systems and social systems demonstrate that there is ample room for productive exchanges among these research communities (Cleveland et. al. 1996). But the results to date indicate as well that we have only begun to tackle the problems of achieving effective communication across these intellectual boundaries. To make progress on the IDGC research agenda we must devise a common discourse that will allow these diverse groups to form a coherent community endeavoring to expand our knowledge of the effectiveness and the robustness of social institutions. The goal here is not to tell individual researchers what to study or to influence their choice of variables, models, or cases. Rather, the objective of this effort is to form an intellectual community whose members know each other's work, employ a common discourse in framing their research problems, and make a concerted effort to compare and contrast the results they obtain. There is no simple recipe that will ensure success in the pursuit of this goal. But the challenge is one that will require IHDP Institutions July 25, 2016 78 careful consideration in the formulation of the IDGC Science Plan and that deserves attention on an ongoing basis among those working on specific projects within the framework of this research program. 9.2 Achieving Analytic Harmonization Because the bulk of the existing research on institutions takes the form of self-contained case studies, students of social practices have not made a concerted effort to harmonize their concepts in the interests of conducting comparative analyses of the effectiveness and robustness of arrangements operating in different settings. There are three distinct problems here that need attention. Individual analysts have often adopted their own concepts rather than adapting a common conceptual framework for use in their own work. There is no standard set of concepts available for use in describing the attributes of social institutions, much less common ways of characterizing the effectiveness and robustness of institutions. Even when they do employ the same terminology, students of institutions often invest individual terms with different content. A prominent case in point is the concept of effectiveness, which has been used to refer to problem solving, goal attainment, compliance, behavioral change, and so forth (Young 1994a). Beyond this, there are many differences at the level of operationalization, even among those who use concepts similarly in analytic terms. How do we operationalize the concept of rules, for instance, especially in cases where rules in use differ from those set forth in constitutive documents or include prescriptions that have evolved through informal processes. These problems are relevant to all research on social institutions But studies designed to produce quantitative findings relating to the effectiveness and robustness of institutions require a particularly strong commitment to solving all of them. IHDP Institutions July 25, 2016 79 It would be undesirable to impose a conceptual straightjacket on students of social institutions. Any effort to do so would undoubtedly backfire in any case. Yet the process familiar to natural scientists as the pursuit of calibration or harmonization is just as important as a basis for the efforts of social scientists to develop cumulative knowledge about the roles institutions play as drivers of global change and as determinants of human responses to largescale biophysical processes. We need reasonable assurance that we are measuring the same things in our efforts to understand the effectiveness and the robustness of institutions. This is particularly true of research dealing with different levels of social organization both because there has not been much exchange of ideas among those looking at the operation of institutions in local societies, national societies, and international society and because there is good reason to believe that some of the most important scientific advances to be made by a program dealing with the Institutional Dimensions of Global Change will come from systematic comparisons of the operation of institutions across levels of social organization. 9.3 Developing Appropriate Databases Another step that is needed to carry out the research program described in this report involves the development of one or several databases containing comparable information on a growing collection of institutions operating at the micro-, meso-, and macro-levels. Such databases will prove helpful to those conducting holistic case studies focused on particular institutions and desiring to compare their findings with the results of parallel studies of other institutions. At the same time, databases are essential for those looking at specific aspects of institutions and desiring to develop and test empirical generalizations across sizable numbers of discrete cases. IHDP Institutions July 25, 2016 80 Consider, for example, the needs of analysts interested in matters like links between the decision rules institutions employ and their capacity to solve problems; between the distribution of material resources among the members and institutional effectiveness, and between the stringency of rules governing the adjustment of institutions and the robustness of such arrangements. Hypotheses pertaining to these matters are of obvious interest to those concerned with the institutional dimensions of global change, and they can only be evaluated systematically as data sets including the relevant variables for a sizable number of cases become available. The creation of a database of this sort is a labor-intensive, timeconsuming, and costly process. It requires a willingness on the part of researchers and funders alike to make major investments of time and resources during the developmental stage, with no guarantee that there will be large payoffs in due course accruing to the community of analysts seeking to explore specific hypotheses dealing with social institutions, much less to the creators of the database themselves. Under the circumstances, it is essential to treat the development of databases as a common enterprise to be fostered and sustained by all those interested in constructing empirical generalizations relating to institutional arrangements. In this connection, it is worth emphasizing that several efforts to construct databases of interest to the IDGC project are already underway. Prominent examples include (1) The International Forestry Research Initiative (IFRI) focused on smallscale systems and based at Indiana University and (2) the International Regimes Database (IRD) oriented toward macro-level arrangements and developed under the auspices of the International Institute for Applied Systems Analysis (IIASA). It is possible that these ongoing efforts can be adjusted to meet at least some of the needs of the IDGC core project. They can also provide numerous insights that will prove helpful to those seeking to assemble the computerized IHDP Institutions July 25, 2016 81 databases needed to back up a systematic effort to broaden and deepen our understanding of the institutional dimensions of global change. 9.4 Formulating Design Principles A major concern of a core project on the Institutional Dimensions of Global Change will be to build up a collection of design principles that address links between various features of institutional arrangements and the achievement of effectiveness and robustness (Underdal 1990). We want to know, for example, whether there are well-defined connections between institutional effectiveness and design features relating to such matters as the character of an institution's rules, decisionmaking processes, implementation review mechanisms, and non-compliance procedures. Conclusions cast in this form will constitute the applied payoff of the research program under consideration here. They can help in pinpointing features of existing institutions that are likely to give rise to anthropogenic disturbances in important ecosystems as well as in designing new institutions needed to ensure that human responses to global changes achieve the intended results. At the same time, the effort to distill design principles from the study of social institutions is of great interest to members of the scientific community. Such an effort bears directly on central theoretical questions regarding whether and how institutions matter as determinants of collective outcomes as well as the relative importance of endogenous versus exogenous factors in accounting for the impacts of institutions in cases where they clearly do matter. The effort to construct design principles should engage all those interested in the institutional dimensions of global change and for two distinct reasons. There are, in the first instance, questions about the range or scope of design principles. Are there some design principles that are universal in the IHDP Institutions July 25, 2016 82 sense that they apply across all levels of social organization, across different conditions regarding institutional linkages, and across a variety of biophysical and social domains? Obviously, such principles should be prized above others, so long as they are not too abstract to apply to concrete situations. Other design principles may apply to identifiable subsets of the universe of institutions, like cases featuring horizontal linkages or coordination problems. Though less desirable than universal principles, such restricted principles are also of considerable value to practitioners, and they may prove a good deal easier to devise than universal principles. Regular efforts to compare notes about the development of design principles should help as well in the ongoing effort to differentiate between real connections and spurious correlations with respect to the impact of social institutions on collective outcomes. A design principle that seems to work in some situations but fails in others, for example, can trigger additional studies that prove fruitful in uncovering spurious relationships and in contextualizing design principles in a way that should help practitioners to avoid the misuse of prescriptive findings. Under the circumstances, it would be appropriate for a core project on the Institutional Dimensions of Global Change to organize regular workshops in which both analysts and practitioners gather to discuss the formulation of design principles and the results flowing from their application to a variety of settings. 10. Connections to Ongoing Programs No matter how successful it becomes, a core project on the Institutional Dimensions of Global Change cannot and should not dominate the overall research agenda on institutions in the social sciences. The initiative under consideration here is predicated on the observation that a considerable volume of high quality research on institutions has already been carried out, IHDP Institutions July 25, 2016 83 is currently in progress, or is presently on the drawing boards. The most effective approach for IHDP to adopt in this area is to connect active researchers in ways that encourage synergy and add value to work already underway or in the planning stage under other auspices. The major goals of an IHDP core project on institutions are thus to (1) integrate, extend, and refine existing findings that are relevant to global environmental change, (2) stimulate, focus, and coordinate research efforts so that they will help fill important gaps or pursue particularly promising areas of study, and (3) bring this intellectual capital to bear on substantive problems that the IHDP or the IGBP has selected for emphasis (e.g. LUCC, IT, and LOICZ). A number of procedures are available to address such matters, and it will be essential for the IDGC core project to take full advantage of these procedures. First, the project should establish a Scientific Planning Committee composed of active researchers interested both in the problems of scale, interplay, and fit and in the substantive issues associated with LUCC, IT, and LOICZ. Second, the project should arrange to assemble analysts who are at the research design stage of new projects in the interests of encouraging individual PIs to harmonize their efforts, even while allowing ample scope for those in charge of specific projects to pursue their own objectives. Third, the IDGC project should organize periodic workshops in which those who are completing projects can compare notes on their findings and discuss the implications of these findings both for subsequent research and for the problems confronting policymakers. Fourth, the project should facilitate regular contacts between IDGC researchers and the leaders of the LUCC, IT, and LOICZ projects in order to explore the applicability of IDGC findings to the concerns of the other projects and to identify specific institutional issues or problems that have surfaced in research conducted under LUCC, IT, and IHDP Institutions July 25, 2016 84 LOICZ and that would benefit from systematic consideration on the part of specialists on institutions. In the course of developing this report, we have identified a number of existing projects that are concerned with matters of interest to a core project on the Institutional Dimensions of Global Change. We list a number of prominent examples here on the explicit understanding that we have not conducted a systematic survey of ongoing projects in this field and that we would welcome information about other projects that should be added to this list as the IDGC project evolves. Center for the Study of Institutions, Population and Environmental Change (CIPEC). This new organization at Indiana University, funded by the National Science Foundation under its human dimensions of global change program, administers both the International Forestry Research Initiative (IFRI) directed by Elinor Ostrom and the land use mapping project directed by Emilio Moran. Beijer Institute Program on Property Rights and the Performance of Natural Systems. This multi-year effort has explored a range of issues relating to resource regimes operating at different levels of social organization and devoted particular attention to what we have described in this report as the problem of fit (Hanna, Folke, and Maler eds. 1996). Foundation for International Environmental Law and Organization (FIELD). This organization directs particular attention to the legal aspects of international resource regimes. It has sponsored important work on the problems of implementing international environmental accords and eliciting compliance from domestic actors (Cameron et. al. 1995). IHDP Institutions July 25, 2016 85 International Regimes Database. This computerized information system was created as part of the International Environmental Commitments (IEC) Project at the International Institute for Applied Systems Analysis. It is intended to offer an ongoing source of data on a wide range of variables of interest to analysts seeking to formulate and test hypotheses dealing with international institutions (Levy, Young, and Zuern 1995). Human Driving Forces of Environmental Change in Southeast Asia and the Implications for Sustainable Development. This project constitutes the human dimensions component of a joint IGBP/IHDP/SARCS initiative focusing on human/environment interactions in Southeast Asia. The project places particular emphasis on issues pertaining to land use and the coastal zone. Program on Sustainable Use of Living Resources of the International Arctic Science Committee (IASC). This program directs attention to large terrestrial and marine ecosystems in which humans are major players. Special attention is given to grazing systems and fish/marine mammal/human systems and to the management practices that have emerged to regulate human/environment relations in these settings. Social Sciences Research Council (SSRC) Committee on the Human Dimensions of Global Change. This ongoing committee played a leading role in early efforts to frame research on the human dimensions of global change. It was the principal sponsor of the first Open Meeting of the Human Dimensions of Global Environmental Change Research Community held in June 1995. IHDP Institutions July 25, 2016 86 11. Next Steps This document describes a single step in an ongoing process. The IHDP Scientific Committee, at its May 1995 meeting, asked us to prepare a short memorandum exploring how the study of institutions might fit into the evolving IHDP program. After reviewing this memorandum at its September 1995 meeting, the committee asked us to develop our ideas into a preliminary scoping report. To respond to this request, we organized a small workshop at Dartmouth College in January 1996 and prepared a preliminary Scoping Report on institutions on the basis of the discussion occurring there. The IHDP Scientific Committee considered that report at its May 1996 meeting, asked us to produce a full Scoping Report by the end of the calendar year, and decided to attach priority to the Institutional Dimensions of Global Change (IDGC) as a prospective IHDP core project. Specifically, the committee concluded that the IDGC project fits well into its overall strategy of integrating projects dealing with substantive themes (e.g. LUCC, IT) with projects that address cross-cutting concerns (e.g. institutions, individual perceptions/ values). This document constitutes the full Scoping Report developed in response to the committee's request. Assuming that the committee approves this product and decides to move ahead with a core project on institutions, we see the following sequence of steps needed to achieve this goal: Consultation with the science community. Regular consultation with the relevant science community is essential at all stages in the development of a global change core project. We have already initiated this process with sessions at the June 1996 meeting of the International Association for the Study of Common Property (IASCP), which was attended by 80-90 people, IHDP Institutions July 25, 2016 87 and at the August 1996 workshop on "Globality in the Context of Human Dimensions of Global Change," which took place at Linkoping University. At this stage, we have plans to present the full Scoping Report at the annual meeting of the International Studies Association in March 1997 and at the Open Meeting of the Human Dimensions of Global Environmental Change Research Community to be held in June 1997 at the International Institute for Applied Systems Analysis. Establishment of a Scientific Planning Committee. Subject to approval of the IHDP Scientific Committee, we propose to form an IDGC Scientific Planning Committee early in 1997. Initially, this group would function as an informal advisory panel with a mandate to bring a variety of perspectives into the planning process and to provide feedback on documents emerging from this ongoing process. The planning committee would be asked to participate actively in the development of the IDGC Science Plan during 1997. We anticipate that this planning group will also form the nucleus of a more formal Scientific Steering Committee once IDGC is established officially as an IHDP core project. Formulation of a Science Plan. The next step in the planning process involves moving from this full Scoping Report to a substantive Science Plan for IDGC. We propose to organize a workshop during the summer of 1997 that will bring together about 25 researchers representing a range of perspectives on institutions as well as the substantive concerns of LUCC, IT, and LOICZ for a focused discussion of the contents of the IDGC Science Plan. Each participant will receive a copy of the full Scoping Report well in advance of the workshop and be asked to come to the workshop prepared to address specific research opportunities relating to some part of the agenda articulated in the Scoping Report. On the basis of these presentations and the exchange of IHDP Institutions July 25, 2016 88 views that they stimulate, we will prepare a draft IDGC Science Plan for consideration by the IHDP Scientific Committee during the fall of 1997. Assuming the committee approves the plan, we will revise it and prepare it for publication as an IHDP/IGBP Report early in 1998. We have submitted parallel proposals to the National Science Foundation (NSF) in the United States and to DG XII of the Commission of the EC in Europe for funding to cover the cost of the 1997 workshop. Publication of an edited collection. If the presentations made at the summer workshop are of sufficiently high quality, we will collect them and arrange for their publication either as an edited volume or as a special issue of an appropriate journal (the editor of the International Political Science Review has already expressed interest in this prospect). Such a collection could begin with a revised version of the analytic portions of this Scoping Report and include a set of chapters outlining approaches to the problems of scale, interplay, and fit as well as a set of chapters discussing the relevance of these concerns to the research agendas of LUCC, IT, and LOICZ. Initiation of a Core Project Office. Once the IDGC Science Plan is approved and prepared for publication as an IHDP/IGBP report, the next step will be to open a Core Project Office to work with the IDGC Steering Committee in administering the IDGC project. We expect to apply for funding to support a Core Project Office during the second half of 1997 with the goal of opening this office early in 1998. IHDP Institutions July 25, 2016 89 12.
