Ecological economics

Organizations:Ecological economics (also called eco-economics, ecolonomy or bioeconomics of Georgescu-Roegen) is both a transdisciplinary and an interdisciplinary field of academic research addressing the interdependence and coevolution of human economies and natural ecosystems, both intertemporally and spatially. By treating the economy as a subsystem of Earth's larger ecosystem, and by emphasizing the preservation of natural capital, the field of ecological economics is differentiated from environmental economics, which is the mainstream economic analysis of the environment. One survey of German economists found that ecological and environmental economics are different schools of economic thought, with ecological economists emphasizing strong sustainability and rejecting the proposition that natural capital can be substituted by human-made capital (see the section on Weak versus strong sustainability below).Nitrogen cycleWater cycleCarbon cycleOxygen cycle Ecological economics (also called eco-economics, ecolonomy or bioeconomics of Georgescu-Roegen) is both a transdisciplinary and an interdisciplinary field of academic research addressing the interdependence and coevolution of human economies and natural ecosystems, both intertemporally and spatially.

One survey of German economists found that ecological and environmental economics are different schools of economic thought, with ecological economists emphasizing strong sustainability and rejecting the proposition that natural capital can be substituted by human-made capital (see the section on Weak versus strong sustainability below). Ecological economics was founded in the 1980s as a modern discipline on the works of and interactions between various European and American academics (see the section on History and development below). The related field of green economics is, in general, a more politically applied form of the subject. According to ecological economist Malte Faber, ecological economics is defined by its focus on nature, justice, and time. Issues of intergenerational equity, irreversibility of environmental change, uncertainty of long-term outcomes, and sustainable development guide ecological economic analysis and valuation. Ecological economists have questioned fundamental mainstream economic approaches such as cost-benefit analysis, and the separability of economic values from scientific research, contending that economics is unavoidably normative, i.e. prescriptive, rather than positive or descriptive. Positional analysis, which attempts to incorporate time and justice issues, is proposed as an alternative. Ecological economics shares several of its perspectives with feminist economics, including the focus on sustainability, nature, justice and care values. The antecedents of ecological economics can be traced back to the Romantics of the 19th century as well as some Enlightenment political economists of that era. Concerns over population were expressed by Thomas Malthus, while John Stuart Mill predicted the desirability of the stationary state of an economy. Mill thereby anticipated later insights of modern ecological economists, but without having had their experience of the social and ecological costs of the Post–World War II economic expansion. In 1880, Marxian economist Sergei Podolinsky attempted to theorize a labor theory of value based on embodied energy; his work was read and critiqued by Marx and Engels. Otto Neurath developed an ecological approach based on a natural economy whilst employed by the Bavarian Soviet Republic in 1919. He argued that a market system failed to take into account the needs of future generations, and that a socialist economy required Calculation in kind, the tracking of all the different materials, rather than synthesising them into money as a general equivalent. In this he was criticised by neo liberal economists such as Ludwig von Mises and Freidrich Hayek in what became known as the socialist calculation debate. The debate on energy in economic systems can also be traced back to Nobel prize-winning radiochemist Frederick Soddy (1877–1956). In his book Wealth, Virtual Wealth and Debt (1926), Soddy criticized the prevailing belief of the economy as a perpetual motion machine, capable of generating infinite wealth—a criticism expanded upon by later ecological economists such as Nicholas Georgescu-Roegen and Herman Daly. European predecessors of ecological economics include K. William Kapp (1950) Karl Polanyi (1944), and Romanian economist Nicholas Georgescu-Roegen (1971). Georgescu-Roegen, who would later mentor Herman Daly at Vanderbilt University, provided ecological economics with a modern conceptual framework based on the material and energy flows of economic production and consumption. His magnum opus, The Entropy Law and the Economic Process (1971), is credited by Daly as a fundamental text of the field, alongside Soddy's Wealth, Virtual Wealth and Debt. Some key concepts of what is now ecological economics are evident in the writings of Kenneth Boulding and E.F. Schumacher, whose book Small Is Beautiful – A Study of Economics as if People Mattered (1973) was published just a few years before the first edition of Herman Daly's comprehensive and persuasive Steady-State Economics (1977). The first organized meetings of ecological economists occurred in the 1980s. These began in 1982, at the instigation of Lois Banner, with a meeting held in Sweden (including Robert Costanza, Herman Daly, Charles Hall, Bruce Hannon, H.T. Odum, and David Pimentel). Most were ecosystem ecologists or mainstream environmental economists, with the exception of Daly. In 1987, Daly and Costanza edited an issue of Ecological Modeling to test the waters. A book entitled Ecological Economics, by Juan Martinez-Alier, was published later that year. He renewed interest in the approach developed by Otto Neurath during the interwar period. 1989 saw the foundation of the International Society for Ecological Economics and publication of its journal, Ecological Economics, by Elsevier. Robert Costanza was the first president of the society and first editor of the journal, which is currently edited by Richard Howarth. Other figures include ecologists C.S. Holling and H.T. Odum, biologist Gretchen Daily, and physicist Robert Ayres. In the Marxian tradition, sociologist John Bellamy Foster and CUNY geography professor David Harvey explicitly center ecological concerns in political economy. Articles by Inge Ropke (2004, 2005) and Clive Spash (1999) cover the development and modern history of ecological economics and explain its differentiation from resource and environmental economics, as well as some of the controversy between American and European schools of thought. An article by Robert Costanza, David Stern, Lining He, and Chunbo Ma responded to a call by Mick Common to determine the foundational literature of ecological economics by using citation analysis to examine which books and articles have had the most influence on the development of the field. However, citations analysis has itself proven controversial and similar work has been criticized by Clive Spash for attempting to pre-determine what is regarded as influential in ecological economics through study design and data manipulation. In addition, the journal Ecological Economics has itself been criticized for swamping the field with mainstream economics. Various competing schools of thought exist in the field. Some are close to resource and environmental economics while others are far more heterodox in outlook. An example of the latter is the European Society for Ecological Economics. An example of the former is the Swedish Beijer International Institute of Ecological Economics. Clive Spash has argued for the classification of the ecological economics movement, and more generally work by different economic schools on the environment, into three main categories. These are the mainstream new resource economists, the new environmental pragmatists, and the more radical social ecological economists. International survey work comparing the relevance of the categories for mainstream and heterodox economists shows some clear divisions between environmental and ecological economists.
