Concerns over population were expressed by Thomas Malthuswhile 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.

InMarxian 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.

In his book Wealth, Virtual Wealth and DebtSoddy 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. Georgescu-Roegen, who would later mentor Herman Daly at Vanderbilt Universityprovided ecological economics with a modern conceptual framework based on the material and energy flows of economic production and consumption.

Other figures include ecologists C. Odumbiologist Gretchen Daily, and physicist Robert Ayres. Articles by Inge Ropke[20] and Clive Spash [21] 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 CostanzaDavid Stern, Lining He, and Chunbo Ma [22] 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.

Nature and Ecology Natural resources flow through the economy and end up as waste and pollution A simple circular flow of income diagram is replaced in ecological economics by a more complex flow diagram reflecting the input of solar energy, which sustains natural inputs and environmental services which are then used as units of production.

Once consumed, natural inputs pass out of the economy as pollution and waste. The potential of an environment to provide services and materials is referred to as an "environment's source function", and this function is depleted as resources are consumed or pollution contaminates the resources.

The "sink function" describes an environment's ability to absorb and render harmless waste and pollution: The economic value of natural capital and ecosystem services is accepted by mainstream environmental economics, but is emphasized as especially important in ecological economics.

Ecological economists may begin by estimating how to maintain a stable environment before assessing the cost in dollar terms. The work was criticized by articles in Ecological Economics Volume 25, Issue 1, but the critics acknowledged the positive potential for economic valuation of the global ecosystem.

Early economists such as Thomas Malthus pointed out the finite carrying capacity of the earth, which was also central to the MIT study Limits to Growth.

Diminishing returns suggest that productivity increases will slow if major technological progress is not made. Food production may become a problem, as erosionan impending water crisisand soil salinity from irrigation reduce the productivity of agriculture.

Ecological economists argue that industrial agriculturewhich exacerbates these problems, is not sustainable agricultureand are generally inclined favorably to organic farmingwhich also reduces the output of carbon.Meet Inspiring Speakers and Experts at our + Global Conferenceseries Events with over + Conferences, + Symposiums and + Workshops on Medical, Pharma, Engineering, Science, Technology and Business..
