McGee Received: 22 September 2007 / Accepted: 18 December 2007 / Published online: 19 February 2008 Ó Integrated Research System for Sustainability Science and Springer 2008 Abstract This article explores the special features of the rural–urban transformation in East Asia in the last 30 years within the broader context of the development strategies of Asian governments. Despite an ongoing commitment to the rhetoric of concern with rural development, food security and the alleviation of rural poverty, these policies have emphasised the important role of urbanisation as the prime process influencing economic growth. This is supported by the economic argument that the economies of scale, the creation of mass urban markets and the higher productivity that occur in urban places make them crucial to development. This paper argues that this approach creates a false dichotomy between rural and urban areas, whereas development should aim to increase the linkages between rural and urban areas aimed at producing societal transformations rather than separate rural and urban transitions. The paper then explores the empirical evidence of rural–urban transitions in East Asia with a more detailed case study of China, which is considered to be a crucial example because of the size of its population, the special conditions of market socialism and its institutional capacity to manage the rural–urban transformation. The final section focusses on the importance of developing spatial sensitivity to the management of the rural–urban transformation in the 21st century.

Keywords East Asia Urbanisation Rural–urban linkages Spatial planning Desakota Eco-systems Introduction In the last 30 years, researchers and policy makers in Asia’s developing countries have favoured development strategies that have placed increased emphasis on encouraging urbanisation and structural shifts in their national economies to industrial and service sector activities (World Bank 1993; White 1998). This has occurred despite an ongoing commitment of many Asian governments to the rhetoric of rural development, food security and concerns with persistent rural poverty. The reasons for this focus are numerous, but among them, the conventional economic wisdom that investment in industry and services creates higher returns than agriculture is a powerful mantra. There is also a strong belief that urbanisation is an inevitable part of the process of creating a modern state; indeed, the economies of scale, the creation of mass markets and the higher productivity that occur in urban areas make cities, it is argued, absolutely crucial to the process of development (Lampard 1965). The consequences of this approach are only too obvious, particularly in the rapidly industrialising countries of East Asia1 1 T. G. McGee (&) University of British Columbia, Vancouver, Canada e-mail: tmcgee@interchange.ubc.ca The definitions of East Asia vary considerably. The geographical definition which I adopt in this paper is that of Pacific Asia, which includes China, Japan, the two Koreas, Taiwan (China) and all of the countries of Southeast Asia. 123 156 characterised by rapid urbanisation, increased industrial production and the increasing importance of the urban-based service sector. Of course, these developments have been heightened by the growing integration of the global economy and the restructuring of the economies of the developed world that are part of the much debated process of globalisation (Olds et al. 1999; McGee and Watters 1997). The results of these development strategies in the more developed East Asian economies have been the decline in the proportion of the employed population in agriculture; the depopulation of rural areas, a sharp reduction in the number of family farms and a restructuring of agriculture with growing emphasis on capital intensity, off-farm employment, the employment of migrant farm labour and food imports. Another result is an increase in rural–urban income disparities that accentuates out-migration from the rural areas. At the same time, increased technological inputs into agriculture (the green revolution) from the 1960s onwards have provided the impetuous for a surge in agricultural productivity (particularly in grains) until the 1990s, such that many East Asian countries provided food for the expanding urban labour forces often at state-subsidised prices, which helped keep urban costs of living and wages lower. This enabled these East Asian countries to be more competitive in attracting international investment in the industry and services (Rigg 2001). This brief, and no doubt oversimplified, summary of the prevailing developmental wisdom of East Asian counties is presented as a way of framing the five central issues that I wish to address in this paper. The first is the failure of policy makers and researchers to understand that the urbanisation–industrialisation transition that they see as an inevitable driving force of the modernisation of their states is, in fact, a transformation of both the rural and urban dimensions of their countries in which the linkages between these two sectors are central to the goals of successful development. To put it starkly, it is not possible to preserve agriculture in the way that it has developed historically or divert urban growth into smaller urban centres in rural areas because the rural–urban transformation is occurring in both rural and urban areas and is inextricably linked. Discussions of the distinction between transitions and transformation and the inadequacy of the rural–urban division and the importance of rural– urban linkages are presented in the next section, entitled Transitions or transformations in the development process. Second, the ideas of transitions or transformations in the development process are used to explore the rural–urban transformation in Asia, East Asia and China in order to show how important the contribution of agriculture and its relationship with the urban sector has been to these countries in the success of industrialisation and urbanisation. It will be obvious from this analysis that China is something 123 Sustain Sci (2008) 3:155–167 of a special case, not only because of its ongoing restructuring of the previously planned economy, but also because of its size, regional diversity and the hybridity of the rural– urban transformation, which are discussed in the section titled China: a special case of rural–urban transformation. In Managing the rural–urban transformation: the importance of spatiality, we turn to the issue of the need to understand the spatial dimensions of the urbanisation process as an essential component in the understanding of the urbanisation process in East Asia. Finally, in Managing the rural–urban transition in Asia, I argued that the need to develop new management policies for the rural–urban transformation is crucial to the task of creating sustainable societies. In particular, I argue for the need to develop management policies that recognise the spatial and ecosystems’ consequences of rural–urban transformation that are focussed on the urban margins of East Asian megaurban regions in which the major tensions of the rural– urban transformation are most evident. Transitions or transformations in the development process Most development theory assumes that developing societies are passing through some kind of transition from underdevelopment to development (Rostow 1960; Porter 1990). The pace and change of this process may vary greatly between countries and global sub-regions, but it is a global trend. This idea is encapsulated with the idea of transition from tradition to modernity—the demographic transition which argues that societies pass through stages of low population growth to high population growth and into a phase of slow population growth, and the environmental transition that suggests that, as societies become more developed, they become more sensitive to issues of sustainability in situations where environmental problems are abound. Finally, there is the urbanisation transition that predicts an inevitable shift from low levels of urbanisation to high levels of urbanisation as countries become more developed. These theories of transition are based on three assumptions. First is that these transitions, while they may vary between countries, are inevitable; countries must go through these transitions to become developed. A second assumption is that these transitions are linear and proceed through a series of stages, which, although they may vary in their length between countries, are necessary prerequisites for development. Third, transition theory adopts a model of the rural–urban transition that assumes a classic model of rural–urban dichotomy. Basic to this conception is the idea of a division between rural and urban that is reflected in the spatial and administrative structures of Sustain Sci (2008) 3:155–167 societies (Champion and Hugo 2004; Montgomery et al. 2003). Thus, transition theory assumes a spatial reordering of countries as an important part of the process of development. It is central to the argument of this paper that transition theory is flawed as a model to investigate the development in East Asia today. On the face of it, this may seem to be a surprising assertion, as, patently, many of the developed countries of East Asia, Japan, the Republic of Korea, Taiwan (China) and Malaysia appear to have experienced transitions broadly conforming to transition theory. But I would argue (following Marcotullio and Lee 2003) that the conditions of the transition they have experienced are very different for the pace of the transition that is occurring is at a very much faster rate than that of early transitions. Marcotullio and Lee have argued, with respect to the environmental transition, that the ‘‘... unique feature of the present era is the compression of the time frame in which the transitions are occurring’’ (Marcotullio and Lee 2003 p. 331; Marcotullio 2003). This is clearly illustrated in Fig. 1, which shows the changes in the levels of urbanisation between England and Wales, Mexico and China. As is clear from the figure, China will take only half the time to reach levels of urbanisation compared to that of the other two (100 years) and, of course, the number of people involved in this shift to higher urban levels will be much larger. Marcotullio and Lee further argue that transitions are now overlapping ‘‘in a telescoping of the transition process in a much shorter time-frame than earlier.’’ (Marcotullio and Lee 2003 p. 331; Marcotullio 2003). I find this concept of the telescoping of transitions very helpful in interrogating the concept of the rural–urban dichotomy that is central to transition theory. Fundamental to the idea of telescoping transitions (also called ‘‘time– space telescoping’’) is the idea that they are being driven by accelerated transactional flows of people, commodities, capital and information between, and within, countries. Most obviously, the flows of capital and information can Fig. 1 Telescoping transition. The increase in urbanisation levels of England and Wales, Mexico and China 157 occur almost instantaneously (unless there are institutional or technological restraints), while the movement of people and commodities have become much faster over the last 50 years. The international components of this transactional revolution are generally referred to as part of a new era of globalisation in which foreign investment encouraged by national states is an important component. The different character of the transactional revolution places much more emphasis on the flows of people, commodities, information and capital within national space economies in which rural–urban flows are only one part of many flows within countries that include regional transactions and urban-to-urban transaction flows between the transaction nodes of nations (see Fig. 2). Thus, development is seen as occurring in a dynamic sense as a process of the transformation of national economic space in which interaction and linkage is a more accurate reflection of reality than the idea that rural and urban areas are undergoing somehow spatially separated transitions. Thus, there is a strong argument for revising the concept of the rural– urban transition as a transformational process that views developmental changes as occurring in national space in which rural and urban are becoming increasingly intermeshed in a common transformational process. In other words, we no longer need to view the process through a historical lens that does not reflect contemporary reality. In contemporary East Asia, the rural–urban transformation is fundamentally driven by a network of linkages that provides a dynamic spatial frame of flows of people, Fig. 2 The globalisation transactional space 123 158 commodities, information and capital. Of course, in large nations such as China or India, this interaction may be more difficult in geographically isolated areas, but, even here, the new transactions in information offers possibilities for increased interaction. This means the acceptance of this concept of transformation as involving developmental change that flows through networks that ignore the rural and urban divisions of political and economic space. The recognition of these ‘‘transcending networks’’ enables the researcher to reassess assumptions about rural activities (note, not rural areas) that they are playing a negative role in development that have been discussed earlier in this paper. Thus, for example, the contribution of agriculture to development can be analysed not as something that only originates in rural areas, but takes into account urban and peri-urban food production. For example, Gale estimates that 10% of the gross value of agricultural output (GVAO) in China in 1997 was produced in urban areas (Gale 2000). I will endeavour to show how this approach can provide a more realistic assessment of the contribution of agriculture to development in East Asia and China in the next two parts of the paper. Transforming rural and urban space in Asia, 1980–2000 In this section, I want to look at two levels of the transformation of rural and urban space. First, at the global level, evaluating the role of Asia’s contribution to the global agricultural production and the global urbanisation process. Secondly, more specifically at the experience of the Asian countries that have nearly completed the transformation from rural to urban societies in East Asia, particularly, Japan, Korea and Taiwan (China). The global picture of agricultural output labour and urbanisation: Asia’s contribution2 An analysis of the state of global agricultural production and agricultural labour trends over the last 30 years indicates that the value of agricultural output in constant USD almost doubled in that period (International Labor Organization 2005). During these years, the labour input (as measured by the number of economically active people in agriculture) increased from around 898 million 2 This section adopts the UN Population Division’s definition of Asia that includes East Asia, South and Central Asia, South East Asia and Western Asia. This is a much more geographically expanded definition of Asia than that generally used. 123 Sustain Sci (2008) 3:155–167 to almost 1.3 billion persons. What is most significant about these patterns of increase is the major growth of the global share that has occurred in Asia, which has grown from 28% to 43% of global agricultural production and 73% to 79% of the global labour share in these 30 years. In the same time period, the global level of urbanisation increased from 36.8% to 47.2% and that of Asia from 23.4% to 37.5%. The UN Population Division estimates suggest that, in the next 30 years, this urbanisation trend will continue at a global level, reaching 60%, while Asia will increase to 51% by 2030. Since Asia contained an estimated 60% of the global population in 2000, this means that, in the next 30 years, some 1.3 billion people will have to be absorbed into urban areas, while the population resident in rural areas remains virtually at the same numerical level of an estimated 2.2 billion (Population Division UNO 2002). The numerical dimensions of these demographic trends are unique in the world experience of urbanisation. For example, in Western Europe, it was estimated that, in the 19th century, the increase of urban levels to 40% involved a shift of only about 50 million people, whereas in Asia, that number is an estimated 1.3 billion. Of course, at the sub-regional and national level within Asia, this demographic picture is dominated by the large developing Asian countries in excess of 100 million in population that include China, India, Pakistan, Bangladesh and Indonesia, which will be joined by the Philippines and Vietnam in the next 30 years. By 2030, these large countries (in excess of 100 million people) will make up almost 80% of Asia’s population and 59% of the global population. These numerical dimensions, thus, present a basic challenge to the management of the rural–urban transformation. The transformed newly industrialised countries: Japan, Korea and Taiwan (China) As we indicated earlier in this section, the group of East Asian countries that are made up of Japan, the Republic of Korea and Taiwan (China) appear to be models for the transformative path from rural to urban society on which China and other Asian countries are now embarked. Together with Singapore and Hong Kong (China), which as city–states are not discussed here, these countries have all experienced rapid urbanisation and industrialisation in the period since 1960 that have led to a rapid rise in national income. The patterns of urbanisation in selected other East Asian countries is also shown for comparative purposes but (with the exception of China) are not discussed here (see Table 1). While these changes in Japan, Korea and Taiwan (China) have been associated with substantial increases in agricultural productivity, none of Sustain Sci (2008) 3:155–167 159 Table 1 Changes in the distribution of gross domestic product (GDP) and urbanisation levels, 1960–1980–2000 Rural–urban trajectory Agriculture 1960 Industry 1980 2000 Services 1960 1980 2000 1960 1980 2000 Type I Taiwan (China) 28 9 3 29 46 35 43 49 62 Japan 13 4 1 45 43 32 42 53 66 Republic of Korea 37 16 5 20 39 44 43 45 51 Malaysia 36 23 9 18 30 51 46 47 40 Thailand Indonesia 40 54 22 26 9 16 19 14 28 39 42 46 41 32 50 35 49 38 Philippines 26 22 16 28 36 32 46 42 52 33 48 57 12 13 10 55 39 33 39 33 15 38 47 46 23 20 39 Type II Type III Myanmar Type IV China Figures for Singapore and Hongkong (SAR, China) are not included because their statuses were 100% urban.

Each of these countries has experienced rural depopulation and the aging of the population that remain in rural areas, and each of these countries has become increasingly dependent upon food imports. All three of these countries share certain common features of high densities, a common historical experience as being part of the Japanese sphere of influence up to the end of the Second World War, land reform and technological innovation post-1946 that has led to a rapid growth in agricultural productivity. Most researchers argue that this initial surge of agricultural production, along with foreign aid and investment, made a significant contribution to the growth of non-agricultural sectors and the transportation infrastructure. These countries also share common experience of rapid industrialisation, agricultural change, high education levels, ‘‘state guidance’’ and ‘‘control’’ in a market economy setting. From the 1960s onwards, all of these three countries focussed on developing a combination of export-orientated and import-substitution industry that was focussed on the corridors that ran between the major urban centres, Tokyo–Osaka, Seoul–Pusan and Taipei–Kaosiung, in which structural change was centred and most of these countries’ populations were living by 2000. These urbanised corridors were closely associated with the main railways systems that linked Taipei (and its port of Keelung) with Kaosiung in the south of the island that had begun in 1898. In a similar manner, the Japanese, by 1928, had established a system of railways and bridges linking Pusan, Seoul and Pyongyang with Sinuiju on the Manchurian border and their own railway systems linking Tokyo with Osaka. In the post-Second World war period, as the independent governments began to develop economically, they accelerated investment in the transportation infrastructure, which, together with the growth of export-orientated industry located both in free export zones and industrial estates, accelerated the concentration of population in the central urban nodes of Taipei–Kaohsiung and Seoul–Pusan. Thus, while in 1960 the population of Seoul and Pusan was 3.6 million or 14% of the national population, by 1975, these cities accounted for 27% of the national population. In most recent years, both Korea and Taiwan (China) have completed fast Shinkansen-type rail linkages that further facilitate the emergence of urbanised corridors similar to the Tokyo– Osaka corridor. Relating these developments to our broader discussions of the first section of this paper, it is clear that the Asian newly-industrialising countries (NICs) have been very successful not only in structural transformation, but also in breaking down the ‘‘friction of distance’’ and reducing transportation costs. In order to accomplish this, the governments had to appropriate and 123 160 dominate their national territory and adopt various spatial practices, such as the allocation of public capital and loans to transportation and communications, which were central to the growth of urbanisation and the decline of the rural population. While some researchers like to attribute this success to the role of ‘‘unfettered capitalism,’’ this is surely an oversimplification. The transactional environments of these NICs where goods, people and commodities move very fast is very much the consequence of the governments’ desires to ‘‘annihilate’’ distance in their nations (McGee and Lin 1993). China: a special case of rural–urban transformation At present, China appears to be exhibiting many of the same features of the rural–urban transformation that occurred in the case of Japan, Korea and Taiwan. Since 1978, it has been experiencing increasing agricultural productivity, increased rural–urban migration and growing industrialisation and urbanisation focussed on the coastal zone and the large extended metropolitan regions of Shenyang–Dalian, Beijing–Tianjin, Shanghai– Hangzhou– Nanjing and Hong Kong–Guangzhou–Macao. For example, it was estimated in 1999 that some 45% of GDP, 33% of industrial output, 75% of utilised foreign direct investment and 75% of China’s exports were produced in these four extended metropolitan regions that contained 10% of the population in 2000 (McGee et al. 2007). This pattern of development has led to increasing disparities in income between the predominantly urban provinces of the coastal zones and the poorer provinces of Western and Central China that are becoming a major national policy concern that is addressed in the 11th Five Year Plan (Ewing 2006). Thus, on the face of it, it would seem that China is following the development trajectory of Japan, Korea and Taiwan (China). For a number of reasons, the prospect that China may be duplicating the developmental trajectories of the transformed East Asian NICs raises concerns among many groups (international agencies, non-governmental organisations [NGOs] etc.) that this route may create serious problems of environmental sustainability not only nationally, but also globally (Brown et al. 1995). Writers from these groups point out that China, with a GDP in 2002 of USD 1,272 billion, was the world’s sixth largest economy at current exchange rates but second in purchasing power parity (PPP), is becoming a key player in the global economy. This advance has been accompanied by a rapid growth in trade and investment. Second, they point out that China has the world’s largest population with 1.3 billion heads, which is 21% of the world’s total. 123 Sustain Sci (2008) 3:155–167 Despite a very high growth rate of GDP in the period between 1991 and 2003, which has averaged 9.0%, the GDP per capita in 2002 was still USD 1,000, which qualifies China as a lower middle income country. This means that, as China moves towards higher levels of GDP per capita income and becomes more urbanised, the demands on the environment will increase substantially. Third, given China’s commitment to the development of auto-centred transport systems, including private cars, motorbikes, trucks and various forms of public transportation, such as buses and mini-buses, this will place increasing pressure on land and energy as China continues to urbanise. A major feature of these auto-centred forms of transport is that they demand increasing space for roads, parking and exchange points. Thus, these systems include ‘‘... an extensive material infrastructure of roadways, service and repair facilities, storage space and an extensive social infrastructure of elaborate bureaucracies’’ (Freund and Martin 1999). The emphasis on the auto-centred city is also supported by a culture of ‘‘automobility’’ that is encouraged by the car manufacturing industry, the desire of middle and upper income class consumers to own cars and national development strategies that foster the growth of a national car industry, often in conjunction with international car manufacturers. Thus, these auto-centred systems encourage the outward spread of urban-based activities (residence, work and leisure), which are complimented by state policies of industrial decentralisation to urban margins and the need for linkages to transport nodes, such as ports and airports. Spatially, these forces are focussed on the urban margins of Chinese cities and particularly in the coastal zones of China, where some of the most fertile and productive agricultural land of China is located. Although China’s land area is huge, cultivated land accounts for only 130 million hectares, or 13.5% of China’s land surface, most of it located in the eastern region, the region of the most rapid urbanisation and the greatest loss of good agricultural land. The population is also unevenly distributed, with almost 90% of the population living on less than 40% of the land area. This creates great demands on the available resources, such as water, land and energy, which are needed as inputs for the rapidly urbanising society. As a result, China faces many challenges in creating a sustainable and livable society over the next few decades. While much attention has been paid to China’s strong economic performance over the last two decades, much of this success has been attributed to the growth of industries, services and the expansion of urban markets. At the same time, the agricultural sector has also been an important contributor to this growth, despite a fall in its contribution to the GDP from 28% in 1990 to 15% in 2003. The agriculture sector still provided about 40% of employment in Sustain Sci (2008) 3:155–167 2003, which has fallen by 15% from 1990, despite overall increases in productivity per hectare from 1980. Thus, between 1990 and 2003, the GVAO almost doubled. This increase was attributable to three main policy decisions. First, the dismantling of the collective production systems and the introduction of the household responsibility production system (HPRS), in which farmers leased the land from the collective. Second, the rapid growth of Township and Village Enterprises from the early 1980s has greatly increased the opportunities for off-farm employment opportunities and growing markets for agricultural products. Third, the national policy of the mid-1990s to encourage the growth of urban centres, as a principle strategy for modernisation. The success of the policies have led to a shift in consumer demand for food products from cereals to livestock and fish and a transformation in the composition of agricultural production. While cereal crops accounted for 65% of the total value of primary production in 1990, their share fell to 50% in 2003. During the same period, the share of livestock production increased from 26% to 32% and fisheries from 5% to 14% (OECD 2005, 2005; Gao and Chi 1997; Carter et al. 1996). While these developments occurred throughout China, the major impact was in the eastern coastal zone, which experienced the most rapid industrialisation and urbanisation. Thus, it is clear that, as the urban sector has grown, agriculture has also been undergoing a transformation and that the two sectors are inextricably linked in the process of development. However, this does not mean that this agricultural transformation is without its challenges. First, agriculture is still on an overwhelmingly small scale. In 2005, there were about 200 million farm households, with an average land allocation of 0.56 Ha . This means that, while the productivity per unit of land is high, the output per worker is low and, despite growing rural incomes, the disparity between rural and urban incomes has been increasing. While China had been somewhat successful in limiting the outflows of rural migrants to urban areas, particularly in the 1980s, these flows have begun to accelerate in the 1990s as movement restrictions have been eased or not enforced. There will be still a major challenge of managing the shift of almost 500 million Chinese from rural areas into urban areas in the next 30 years. While the supply of inputs (e.g. fertiliser) and the marketing of agricultural products have begun to diversify as State Trading Enterprises become less important, the farmers still have trouble accessing the credit that will enable them to change their production systems to improve the quality of their product, which are demanded by food processors and retail chains that are growing in the urban areas. Undoubtedly, growing urban demand will make this a necessity in the next ten years as the consumer markets of the urban areas grow. 161 Agriculture is also faced with other challenges that are a consequence of this rural–urban nexus. It is estimated that some 20% of agricultural land has been lost to urban expansion over the last 20 years and, despite its size, there is limited possibilities of the expansion of cultivated land (Lin and Ho 2005). The growing use of intensive chemicaluse farming systems is beginning to affect water systems. At the same time, the by-products of urban and industrial growth are leading to increased environmental problems that affect the agricultural production. These challenges precipitate a careful consideration of the management of the rural–urban transformation. Central to the argument of this paper is the assertion that China has at least six advantages in accomplishing this rural–urban transformation. First, to adopt a well-known argument, China is a late arriver in the development process and has, therefore, the opportunity to take advantage of previous transformations and to look for positive examples from other countries that are most suitable for its local context. Second, China is experiencing the rural– urban transformation at a unique period of globalisation, which gives its government access to information and technologies, such as geographic information systems (GISs) that can be applied to the management of the rural– urban transformation. Third, China is able to engage the management of the rural–urban transformation as a state project that is part of what Scott has called ‘‘high modernist ideology.’’ He defines this as a ‘‘version of self confidence about scientific and technological progress, the expansion of production, the growing satisfaction of human needs, the mastery of nature (including human nature) and above all the rationale design of the social order commensurate with the scientific understanding of natural laws’’ (Scott 1998). The language of the 10th Five Year Plan captures this ideology splendidly (New Star Publishers 2001). Fourth, this project of the rural–urban transformation is being filtered through a series of administrative scales from national to local that are increasingly characterised by decentralisation and local control. This means that there is much more opportunity for local involvement in the rural– urban transformation. Fifth, I would argue that, while economic decisions on investment are an important part of this process, the rural– urban transformation is primarily an institutionally driven process and that China has been very successful in making institutional adaptations in the post-reform period. For example, the growth of urbanisation in China in the last decade has been dominated by the state-led replacement of rural space by urban space. This is accomplished through the creation of provincial level municipalities (e.g. Chonqquing), the expansion of existing municipalities (e.g. Guangzhou), the reclassification of 123 162 counties to municipalities (e.g. Dongguan, Kunshan) and the creation of new urban spaces (e.g. Shenzhen, Zhuhai) and the amalgamation of townships. This process of the reshaping of administrative space is, thus, extending the spatial control of urban areas over former rural areas and creates both opportunities and problems in the rural–urban transition (Ma 2005; Chung and Lam 2004). This process of the expansion of urban space has been facilitated by the state separating land-use rights from landownership and the opening up of a new market track for the conveyance of land-use rights to commercial users. Now, all land transactions involve some form of leasing but not the transfer of property rights and the periods of leases have progressively extended. In urban areas, this meant that land formerly occupied by state-operated enterprises could be leased for commercial purposes. In rural areas, land was defined as collectively owned and the leasing of land was more complicated because, while the state was attempting to limit the conversion of agricultural land in rural areas to other purposes (primarily for reasons of food security), it has allowed the institutional units of the rural collective (villagers’ committees, village economic cooperative or township collective economic entities) to allocate rural land for other uses subject to the approval of the Land Bureau at the county level. Despite the many efforts of the central government to slow down the rate of approvals, they have continued apace, leading to an increasing use of rural land for non-rural activities and, as the spread of urban political power into these rural areas ensued, there has been much social and economic discontent among the rural population. This is further accentuated by state efforts to rationalise land-use to avoid environmental problems and create more livable societies that has led to a proliferation of industrial zones in the margins of the city cores. These programmes are further promoted by the need to increase the quality of production to conform to the regulatory environment that has to be set up as a consequence of the admission to the WTO in 2001 (Lin and Ho 2005). Sixth, despite the size of its population, China has been able to successfully reduce its rate of population growth because of its ‘‘one child policy’’ and, in addition, avoided the surge of rural migrants to urban areas in the first decade of the reform era though residence permits (hukou), thus, preventing the growth of informal squatter settlements that are a ubiquitous feature of urbanisation in other developing countries. For a brief moment in history, it seemed that China may have experienced a unique lag in rural–urban migration at a time of increasing economic growth, but in the decade of the 1990s, this rural–urban migration has accelerated, although tending to locate primarily in the peri-urban margins of the cities. But these advantages must be set against the problems that are created because of the relative imbalance in 123 Sustain Sci (2008) 3:155–167 investment between the rural and urban areas. This is primarily explained by the rapidly integration of China into the global economy. Scott and others have argued that the present phase of globalisation is creating a new ‘‘social grammar of space in which the whole edifice reposes upon a geographical foundation that can be best described as a mosaic of city regions constituting the economic motors of the global economy’’ (Scott 2001). What we are describing here is an intensely competitive system in which the megaurban regions of China, like those in other parts of the world, are competing to capture some portion of these transactions generated at both national and international levels. Thus, there is increasing pressure upon governments at both the national and city level to create an urban environment that will increase the flow of transactions to the mega-urban region. Olympic games, major attraction sites such as Disneyland, new airports, convention centres, multi-media corridors, urban renewal and industrial estates in peri-urban areas are all parts of packages that are designed to make urban regions more attractive. In some of the transformed NICs, such as Japan, Korea and Taiwan (China), these developments have the capacity to generate countervailing forces within the city regions, in which civil society movements begin to pressure for more investment in livable regions than globalising cities. This creates an ongoing tension between growth-orientated policies and those directed towards creating more livable urban regions (Ma and Wu 2005). This tension begins to assume a spatial dimension in the fiscal imbalance in the investment between the central city cores and its suburbs of the mega-urban regions are being transformed to make them more attractive to the forces of globalisation involving major the investment of public and private capital in the enticing built environment of globalisation. For example, at a national meeting held in 2005, Wang Guangtao, Minister of Construction, criticised these strategies, claiming that 183 cities had vowed to build themselves into international metropolises with so-called ‘‘show-off projects,’’ such as open city squares, luxury office buildings and airports. One writer has reported that ‘‘most of urban China has been built in the past 25 years at a rate of 150 million square metres per year, often on large projects. This rate of urban expansion is unprecedented...’’. This surge of urbanisation is generating a huge demand for capital. One estimate of the annual costs of Chinese urbanisation is 300–500 billion yuan (USD 37 billion), which is roughly 2–4% of the Chinese GDP in 2004 (Sustainable Development Research Group 2005). This growth in capital demand has generated a huge amount of borrowing. A report by the State Development Corporation in 2002 estimated that the total debt borrowed by local government equals one trillion yuan. On the other hand, the urban margins and rural areas are being under-supplied Sustain Sci (2008) 3:155–167 with services and public and private investment is smaller, with much less investment. A second spatially focussed issue that affects the rural– urban transformation is the growing demand of central city cores and their suburbs for resources, such as water, land, building materials, labour, recreation space and waste disposal sites in the urban margins and rural areas, which have serious impact upon agriculture in these areas. As we have already pointed out, the more positive side of this urban impact is that the growing markets of cities are increasing demand for higher value food products, such as animals, fish and fruit. Farmers in these peri-urban areas are rapidly changing to the production of these commodities. A final issue in rural–urban relations relates to the ongoing migration from rural to urban areas. Since this has been the focus of much academic and policy attention, I will not deal with the process in detail, except to point out that the actual movement of migrants is still very much the tip of an iceberg and will accelerate in the next two decades. Social problems may well be accentuated, particularly if urban poverty increases as vulnerability to global trade cycles increases. Therefore, there will be increasing pressure on all levels of the government to increase investment in social overhead capital, such as education, health and housing in urban areas. Experience in other Asian developing countries does not suggest that investment in rural areas will stem this exodus (Douglass 2001). Thus, there is an ongoing tension in the rural–urban transformation process that involves careful and innovative management. In much of this section, we have argued that China, because of its unique historical, geographical and institutional features, is developing a form of hybrid response to its rural–urban transformation that combines endogenous and international elements. The Chinese approach to the rural–urban transformation is a process of experimentation, constantly changing and adapting to the realities of the immediate situation at all scales, from international to local. Nee (1992) captures the essence of this approach in the following quote: ‘‘Rather than conceive the market transition as a linear progression to capitalism, we may analyze the departures from state socialism as likely to produce hybrid market economies that reflect the position of the institutional centricity of their parent institutional form.’’ Managing the rural–urban transformation: the importance of spatiality This preceding discussion of the rural–urban transformation in East Asia and China raises many policy challenges 163 concerning the most effective way to manage the rural– urban transformation. There are three policy assumptions that underlie my discussion here. First, there is a need to recognise that the rural–urban transformation process in the developing countries of Asia (including China) poses serious challenges to the eco-systems of these countries. In this discussion, we refer only to the local features of the eco-systems, but it must also be recognised that the urbanisation process creates broader global environmental problems, such as global warming. Second, there is a need to accept the fact that policy intervention is a necessary prerequisite for a sustainable rural–urban transformation. Third, there is a need to think of the rural–urban transformation as one in which the networks of rural–urban relations are being changed as much as the places that are thought to be rural and urban. The implications of accepting the fact that rural–urban transformation has crucial impacts on eco-systems means that there must be further clarification of this concept. While there are many definitions of eco-systems, we believe the one that best suits the rural–urban transformation is idea of the eco-system that involves the dynamic interaction between people and their environment. Of course, this interaction is mediated by the social, political and economic institutions of which the people are part, as well as changes in the environment, e.g. climate change etc. Part of this eco-system provides inputs, water etc. that are necessary for well-being. But these inputs are always being modified by people and institutions of which they are part, so that relations in eco-systems are in a constant state of flux, with urban places and non-urban places functioning as partial eco-systems in which the urban places are generally supported by biophysical processes that occur elsewhere (Rees 1992). But even in dominantly agricultural rural areas, for example, the demand for fertiliser to increase productivity may affect both source areas and the in-situ eco-systems. The crucial part of this approach is that it recognises the fact that the rural–urban transformation is part of an integrated eco-system that is being spatially impacted differentially within the system. In most of Asia, national space has been seen as conventionally divided into three regions (De Koninck 2003). First, the agricultural core regions, which exist in every country, for example, the lower Yangzi in China, Thailand’s central plain and the island of Java. These are all characterised by high densities, intense agricultural activities and are the location of major mega-urban regions, such as the Shanghai–Nanjing–Hanzhou extended metropolitan region, the Bangkok metropolitan region and the Jakarta–Bandung urban corridor. Historically, these core regions have been major centres for the production of basic staples, such as rice, but they are now shifting to non-cereal products. In larger countries, such as India and China, there 123 164 are also many core regions. Second, there are frontier regions that are given over to more extensive agriculture activities, such as livestock farming etc. These areas are ecologically diverse, ranging from coastal locations to mountainous areas. Finally, here are the spatial zones on the peri-urban fringes of the city cores characterised by the most intense interaction between urban and rural processes, which consist of the urban periphery, which I have labelled elsewhere as ‘‘desakota.’’ As urbanisation proceeds, it will be a major force in changing the spatial structure of these regions in Asian countries (McGee 1991). It is important, therefore, that policies do not assume that rural or urban spaces are homogeneous, but they should recognise that they are integrated spaces. Within Asia, there is ample evidence that both rural and urban areas are experiencing different development trajectories shaped by their regional contexts. Thus, with respect to China, Dong (2004) suggests the emergence of four main types of rural area, each of which will involve different policy responses. (1) High amenity rural areas of cultural importance and scenic beauty to proliferate as urban consumers demand increases. These can already be seen emerging in Chengmai in Thailand and in the Yunnan Province in China. (2) Sparsely populated areas where population density is low, incomes are low and limited services are available because of isolated locations. (3) High-poverty rural areas, which exist in pockets more predominantly in interior provinces. It is clear that the 11th Five Year Plan had identified these latter two rural areas as the focus of their public investment over the next five years. (4) Finally, there are the zones of rural–urban interface that exists around many of the larger cities. They present distinctive challenges that, in the short-term, are most problematic for developing sustainable societies in nations such as China. There is a large and growing literature detailing the problems of these peri-urban regions in the Asian context. Part of the literature focusses on the measurement and delineation of these peri-urban zones. The accompanying figures illustrate some hypothetical models of these areas (see Figs. 3 and 4) (Marton 2000; Zhou 1991). There is also a strong emphasis upon the high density of many of these regions, the historical evolution of intense agricultural systems being heavily reliant upon efficient water delivery systems which are subject to rapid change as a result of urban expansion and demands upon the resources of the peri-urban regions that are set within the framework of the emergence of large mega-urban regions. Finally, there is recognition that these peri-urban zones, particularly in countries such as China, where the city cores already have very high densities, will be the location of most urban-orientated growth, absorbing up to 80% of urban increase over the next few decades (Webster et al. 123 Sustain Sci (2008) 3:155–167 Fig. 3 Spatial configuration of a hypothetical Asian country (ca. 2000) Fig. 4 Spatial configuration of an Asian mega-urban region (ca. 2000) 2003). The policy solutions for such regions are not easy, for they are often politically fragmented and there are subregional variations in the eco-systems that create great Sustain Sci (2008) 3:155–167 165 Fig. 5 Model of decision processes in the peri-urban and desakota zones difficulty for policy makers. These developments create a complex managerial environment in which a myriad of polyarchic decision-making at the local level come into conflict with the transformative elements of higher levels of government, business etc., resulting in a decisional congestion (see Fig. 5). Managing the rural–urban transition in Asia The rethinking of the methods of governance and management that this spatial understanding of urbanisation demands is very challenging. Broadly, any institutional response must be at the level of the extended metropolitan region (EMR), and this involves a three-fold commitment. First, at the level of the EMR, there must be a two-fold interpretation of governance as incorporating the exercise of political will and power within the EMR. Second, the management of these EMRs must be directed to ensuring livability and sustainability. Such a vision does not exclude the possibility of city region, public–private partnerships and government–civil society coalitions being formed. Indeed, the administrative spread of China’s cities that we have referred to earlier offers the institutional possibilities to make flexible and innovative management decisions. This, of course, requires the continuation of the regional visioning of EMR space that we see operating between Shenyang and its surrounding industrial cities in Liaonang or the coalitions of mayors in the lower Yangzi river valley. In this respect, Brenner’s carefully articulated review of metropolitan regionalism in the USA and Europe has some relevance. He describes metropolitan regionalism as ‘‘including all strategies to establish institutions, policies or governance mechanisms at a geographical scale which approximates that of existing socio-economic interdependencies within an urban agglomeration’’ (Brenner 1999). Third, there must be a commitment to the preservation of the eco-systems of which these EMRs are part. While it is somewhat unconventional, I would argue that the coexistence of agriculture, industry and other urban activities in a form of a mixed-use landscape offers the most viable option for the preservation of eco-systems within the EMR and producing a livable and sustainable city region. The conventional approach to achieve co-existence between agriculture and non-agriculture is regulatory, based on the zoning of land-use. In the United Kingdom, the concept of a green belt surrounding the urban core became an important part of planning practice, and this has transmuted into the use of ‘‘green spaces’’ that are now seen as a basic necessity to the quality of life of city regions in many developed countries. In this respect, the experience of Japan may provide a model that would have resonance in China and other parts of East Asia. Various reviews of Japanese planning practice emphasise the fact that ‘‘... planners in Japan have attempted to emphasise the positive aspects of agricultural land within urbanizing areas’’ (Nakai 1988), emphasising the role that agriculture plays not only in the provision of food, but also in preserving the eco-system. This suggests the development of new ideas for Japanese EMRs involving the creation of rural–urban mixed settlements, which has been labelled konju-ku in Japan. Such policy initiatives could be implemented at various spatial levels, for example, at the level of the watershed, in which many biophysical processes interact, 123 166 or at the institutional level of the metropolitan region. But for both levels, the idea of a fusion between urban and rural environments and the acceptance of mixed land use is fundamental to planning strategies. Conclusion In a considerable part of East Asia today, characterised by a surging economy, rapid urbanisation and a lagging agricultural sector, the kinds of policy prescriptions that have been laid out in this paper may seem overwhelmingly utopian, but given world trends such as global climate change and increasing energy prices, these policies will be necessary to produce sustainable societies in the 21st century, with changing land use, increasing environmental problems, changes in the built environment and population change in these rapidly changing urban areas. To conclude, the key to managing the rural–urban transformation in East Asia does not involve the blind acceptance of the transition models of urbanisation from the ‘‘west.’’ East Asian countries should be developing their own response to the rural–urban transformation; that is, attempting to manage the interaction between global, national and local forces that drive the transformation using endogenous ‘‘adaptability’’ and adopting a form of ‘‘hybridity’’ in managing the rural–urban transformation process that we elaborated on earlier.
