Ecosystem services, human well-being and quality of life Anna Frąckiewicz annaefrackiewicz@gmail.com Key words: Ecosystem services, human well-being, Human Development Index, Happy Planet Index Introduction Well-being denotes how well people feel about their surrounding and these feelings can be thought of as adding up to quality of life. There are many components of well-being that include health, economic standards of living, social conditions and the physical environment. Traditional measures of well-being have focused on health indicators like life expectancy. Well-being may be also measured in economic terms e.g. standard of living defined as the amount of money and access to goods and services that a person has. Other measures of well-being might include, happiness, environmental health, and development that are far harder to measure. This paper gives overview on human well-being and quality of life as phenomena dependant on and strongly connected with ecosystem services. The findings of Millennium Ecosystem Assessment about different constituents of well-being will be presented. Example indices concerning well-being will be briefly reported. Definitions According to the EPA ecosystem services are defined as the products of ecological functions or processes that directly or indirectly contribute to human well-being, or have the potential to do so in the future [6]. The Millennium Ecosystem Assessment (MA) defines ecosystem services in an even simpler, very anthropogenic way, as the benefits people derive from ecosystems. These include provisioning services such as food and water; regulating services such as regulation of floods, drought, land degradation, and disease; supporting services such as soil formation and nutrient cycling; and cultural services such as recreational, spiritual, religious and other nonmaterial benefits [1]. [more info – Ecosystem goods and services ] The well-being should be understood as “state of happiness, good health and/or prosperity” whereas quality if life is the degree of well-being felt by an individual or group of people. It consists of two components: physical and psychological. The physical aspect includes such things as health, diet, and protection against pain and disease. The psychological aspect includes stress, worry, pleasure and other positive or negative emotional states[8] 1 Millennium Ecosystem Assessment Findings According to the findings of the Millennium Ecosystem Assessment ecosystem services are strongly interlinked with different constituents of human well-being. There are several key components of human well-being: the basic material needs for a good life, health, good social relations, and personal security, freedom of choice and action The relationships are schematically shown in the figure below. Fig. 1 Relationships among ecosystem services and human well-being.[1] [more information - Ecosystem services and Millennium Assessment ] 2 Dependence of constituents of well-being on ecosystem services Basic material for good life refers to the ability to have a secure and adequate livelihood, including income and assets, enough food and water at all times, shelter, ability to have energy to keep warm and cool, and access to goods. Access to basic material for a good life is strongly linked to both provisioning services such as food and fiber production and regulating services, including water purification. It is obvious that many of material factors (food, clear water, shelter, clothing) are essential for human life. However access to these materials is often heavily mediated by socioeconomic circumstances. Healthy person is the one who is adequately nourished and free from disease, has access to adequate and clean drinking water and clean air. Health is strongly connected to both provisioning services such as food production and regulating services, including those that influence the distribution of disease-transmitting insects and of irritants and pathogens in water and air. Health can also be linked to cultural services since they affect spiritual, inspirational, aesthetic, and recreational opportunities, and these in turn affect both physical and emotional states of people. The links between ecosystem change and human health are complex because they are often indirect, differ in space and time, and are dependent on a number of varying factors. The schematic presentation of relationships between human well-being and ecosystem services is shown below. 3 Fig.2 Interrelationship between ecosystem services, aspects of human well-being and human health.[3] Security is understood as a safety of persons and possessions, secure access to necessary resources, and security from natural and human-made disasters. It is affected both by changes in provisioning services, which affect supplies of food and other goods and the likelihood of conflict over declining resources, and by changes in regulating services, which could influence the frequency and magnitude of floods, droughts and disease regulation, climate regulation. It can also be affected by changes in cultural services since they can contribute to the strengthening or breakdown of social networks within community. Good social relations are thought as realization of aesthetic and recreational values, ability to express cultural and spiritual values, development of social capital and avoidance of tension and conflict over a declining resource base. Social relations are affected by changes in provisioning and regulating ecosystem services, basically through their more direct impacts on material well-being. Changes in cultural services are also strongly influencing social relations, as they affect the quality of human experience, particularly in cultures that have retained strong connections to local environments. Freedom of choice and action refer to the ability of individuals to control what happens to them and to be able to achieve what they value doing or being. It cannot be 4 actually achieved without the existence of the other components of well-being and thus is influenced by changes in provisioning, regulating, or cultural services from ecosystems. Measurement of Human Well-Being MA aims at identification of direct and indirect ways the change in ecosystem condition can affect the human well-being positively or negatively. The problem is more complicated if one starts to think how multidimensional well-being is and therefore how hard it is to measure it. However, number of indices have been developed dealing with assessing human well-being at different scales. Below example indices are described. - Human Development Index (HDI) The Human Development Index is a well known index supported by United Nations General Assembly and widely used in policy assessments. It summarizes composite a country's average achievements in three basic aspects of human development: health, knowledge, and a decent standard of living. Health is measured by life expectancy at birth; knowledge is measured by a combination of the adult literacy rate and the combined primary, secondary, and tertiary gross enrolment ratio; and standard of living by GDP per capita. It does not take into account cultural or social aspects of well-being, and it considers security dimensions only insofar as they are reflected in economic and health outcomes.[5] [More info http://hdr.undp.org/en/statistics/indices/hdi/ ] - Happy Planet Index (HPI) The Happy Planet Index is a concept developed by the new economics foundation. It is an index of human well-being and environmental impact. The HPI reflects the average years of happy life produced by a given society, nation or group of nations, per unit of planetary resources consumed. It incorporates three separate indicators: ecological footprint, life-satisfaction and life expectancy in following way: 5 Below the global Happy Planet Index is presented. Fig. 3 Map of world’s Happy Planet Index. [7] [More information - www.happyplanetindex.org ] - U.S. Well-Being Index The Well-Being Index proposed by U.S. Environmental Protection Agency (EPA) is developed as the part of Ecological Research Program Multi-year Plan for 2008-2014. It is independent of time, place and culture and unifies the human and environmental domain. This index will expand the interpretation of ecosystem services indicators into an overall quality of life measurement which could be used in decision making processes. The four sub-indexes have been recognized. human needs sub-index happiness sub-index economics sub-index environmental sub-index Controversies Ecosystem services are clearly necessary, but not sufficient for human well-being. If the material minimum which is essential for human life is attained human well-being becomes very subjective and experimental. Personal expectations, social position and relationships as well as sense of participation and inclusion have relatively little to do with ecosystem services directly. Proper provisioning services surely increase quality of life in developing countries however the influence may not be so strong in developed 6 countries. If one thinks how much quality of life and consequently well-being can be improved due to governmental socioeconomic decisions a decoupling from ecosystem services might be realized. Regarding non-material aspects of human well-being such as good health, a sense of security, good social relations, freedom and choice of action, they should not be confused with life free from all difficulty. Actually life of every human being is subjected to some suffering and pain as well as feeling of anxiety and it does not necessary mean poor human well-being. “It does not necessarily follow that more ecosystem services mean more human wellbeing, or vice versa. It is, for instance, quite widely observed that general improvements in well-being often occur despite, or because of, decreases in ecosystem services, at least at the local scale.”[4] In fact, due to globalization of trade and modernization the societies well-being becomes less dependent on ecosystem services provided by the local environments. Moreover it is plausible that the links between ecosystem services and human wellbeing are complex, diverse, context-dependent. The need to consider different spatial and temporal scales makes the proper assessment even more complicated. All available measures are dealing with the same problems, both conceptual (are they measuring the right thing, in the right way?) and practical (how do we actually implement them?). Moreover, most available measures are extremely difficult to be related to ecosystem services. Conclusions The concept of human well-being is complex and multidimensional. The linkages between human well-being and ecosystem services are even more complex. Even though some of these links are recognized, many remain poorly understood and controversial. The capacity of human communities to form satisfied societies, stable economies, and to plan for the future relies on environmental stability, availability of natural materials, and the adequate functioning of the cleansing and recycling processes of ecosystems. Human well-being has a two-way interaction with ecosystem condition, mediated in the one direction through the services that ecosystems provide to people, and in the other by the largely unintended impacts of human activities on ecosystem functioning [4]. Therefore human transformation of ecosystems and subsequently of services they provide may add up to or reduce the benefits to society. The man-made change to ecosystem may lead to ecosystem services lost, which in long term may exceed the short term economic gains for society. Therefore an appropriate environmental management which takes into account the importance of ecosystem service for quality of life and human well-being should be involved in decision making processes.
