In the 1990s, arguments were advanced to support “structural adjustment programs,” which involve market reforms and deregulation to promote economic growth in developing countries • Amartya Sen (1998 Nobel Laureate in Economics) argues that growth is a means of development but not in itself an appropriate goal of society • The concept of sustainable development is an attempt to locate economic prosperity in a broader ethical and political framework 12 Can Sustainable Development Save Us? The concept of sustainable development (SD) can be seen as a response to the perceived failures of the “growth-as-development” model • SD broadens the focus on material prosperity to include the following three objectives: 1. Alleviating poverty + meeting basic human needs 2. Sustaining natural resources + environmental quality 3. An equitable distribution of income and political power • Amartya Sen (1999) defines development as the extension and improvement of people’s substantive freedoms Sustainable Development seeks to create a new relationship: The three Es’: Equity, Environment, Economics 13 EARLY 1970s Global change emerges on the international agenda on the road to the U.N. Conference on the Human Environment (Stockholm, 1972) • “Less developed countries should be given every assistance and incentive to promote rational environmental management” • Industrialized nations pledged 0.7% of GDP in development aid to the South • The conference stressed that the alleviation of poverty required economic growth, with limits on resource depletion + environmental degradation (Environmental Sustainability) • Transnational pollution (e.g. acid deposition) was identified as a “global problem” that transcends the borders of nation-states 14 Context of Late 1980s… Environmental problems were once viewed in terms of local pollution control or nature conservation/preservation • In the 1980s, however, several new issues were brought into sharp focus by major media events related to global environmental change 1. Ozone depletion: The Antarctic ozone hole was discovered in 1984 crash program to phase out ozone-depleting substances 2. Tropical deforestation: Not a new problem in the 1980s. But deforestation was popularized by a series of catastrophic fires and clever marketing by nongovernmental organizations (NGOs) 3. Looming threat of climate change: Hot summer of 1988 in Washington + growing scientific consensus 15 The Brundtland Report (‘87) U.N. General Assembly creates: World Commission on Environment and Development, to investigate the links between economy & environment; to propose a new “global agenda for change” • Our Common Future (1987) –political document, sets stage for international/interdisciplinary action on environmental issues --Eight key issues were targeted for study: energy, industry, population, food security, human settlements, international cooperation, decision-making systems, and international economic relations. • The Commission was chaired by Gro Harlem Brundtland, then Prime Minister of Norway and future Secretary General of the World Health Organization (‘98-’03) 16 Key Matters from Brundtland Key principle: Defines Sustainable development = “development that meets the needs of the present without compromising the ability of future generations to meet their own needs” • “Development” = “progressive transformation of economy and society” • “Needs” = essential needs for jobs, food, energy, water, and sanitation, with needs of world’s poor as the “overall priority” Main areas for policy action: • Population/human resources • Food security (agriculture) • Preserving species and ecosystems (biodiversity) • Industrial efficiency (pollution and materials) • Energy • Redefining urban environments 17 Brundtland Report (con’t)… • The Brundtland Report called for policies to achieve equity between and within generations • A “change in attitudes, objectives, and institutional arrangements at every level” • Economic growth was still identified as an important component of development. But how it is managed is seen as even more important 18 Economic Growth: Basic Concepts The theory of economic development is grounded in macroeconomics: How economies grow over time due to population growth, capital investment, technological change – Macroeconomists also study inflation and unemployment – This contrasts with microeconomics – the analysis of individual decision-making and behavior in markets Starting point for analysis: How to measure aggregate output/economic activity? – Gross domestic product (GDP): the total value of goods and services produced by an economy in a given year, evaluated at market prices 19 Conventional theory: Economic development = fulfillment of consumer preferences = growth of per capita consumption – How to promote economic growth in developing countries? Free markets work by creating incentives for capital investment + development of new technologies. “Economic development” seen as extension of market mechanism to global economy o This approached commonly termed “neoliberalism” Markets are based on cultural understandings + political/legal institutions. So “development” requires cultural + political reform o Some academics (and NGOs) argue that this can involve imposing Western culture and values on non-Western societies 20 What’s Wrong with this Model? Objections to the “neoliberal” model of economic development: 1. Representing output as a function of labor, capital, and technology ignores the crucial role played by natural resources and environmental quality 2. Defining “development” as increased material consumption ignores the noneconomic components of human well-being 3. Defining “development” in terms of GDP growth ignores the importance of income distribution/economic inequality 21 Objection #1: The role of natural resources – Neomalthusians believe that resource depletion and environmental degradation undercut the biophysical basis of economic activity This is exemplified by the “Limits to Growth” model of 1972 (e.g., Donella Meadows and others) Technological optimists like Bjørn Lomborg believe that free markets will overcome the limits imposed by nature Either of these views is easy to criticize. The truth presumably lies somewhere in-between 22 The techniques of “natural resource accounting” explore the empirical links between natural resources, economic growth, and human well-being – Conventional GDP ignores resource depletion Although natural resources are valuable forms of wealth, no subtraction is made when resources are used up – Repetto et al. (1989) presented a case study of the Indonesian economy GDP growth = 7.1 %/yr for 1971-1984 Indonesia is a major exporter of oil and tropical hardwoods Repetto et al. subtracted the economic value of oil, timber, and soil resource depletion from GDP The corrected rate of economic growth = 4.0 %/yr 23 Objection #2: Defining “development” as increased material consumption overlooks the noneconomic components of human well-being – Richard Easterlin (1974) analyzed the relationship between income and happiness in industrialized and developing nations – Happiness was measured using surveys in which people were asked to rate themselves as “very happy,” “mildly happy,” “mildly unhappy,” or “very unhappy” – Easterlin Paradox: 1. In any country at any point in time, wealthy people seem more satisfied with life than poor people 2. But average happiness has not increased significantly in the US, Europe, or Japan in the last 60 years despite robust economic growth 24 25 Objection #3: PRESENT GLOBAL CONTEXT CHARACTERIZED BY GROWING UNEVEN DEVELOPMENT Dramatic differences in annual % change of per capita GDP (constant 1995$) By 2005 According to World Bank: In dollar terms, the top 5 percent of world population controls almost one-half of world income. They make in 15 hours what the poorest 5 percent make in a year. 10% Annual percent growth in GDP per capita over the given period • 5% 1970-1980 1980-2000 0% -5% -10% Major industrial countries Other advanced economies Developing Countries in Transition -15% 26
