The second, revised edition of his major lifework was retitled Ecological and General Systems: Odum’s contributions to this field have been recognised by the Mars Society. The theoretical and conceptual basis for the emergy methodology is grounded in thermodynamics [ citation needed ]general system theory [2] and systems ecology.

Emergy – Wikipedia

House of Representatives,U. Emergy analysis perspectives of Thailand and Mekong River dam proposals. Odum has been described as a “technocratic optimist”. Energy, ecology and economics. It presented a cogent argument for the limits of industrial growth. Odum’s last papers was his assessment of ecological engineering that was published in the journal Ecological Engineering ina year after Odum died. If the symbols are understood by all, the process of discussion and drawing unites people and thinking around a task with a minimum of semantic problems about meanings.

The recognition of the relevance of energy to the growth and dynamics of complex systems has resulted in increased emphasis on environmental evaluation methods that can account for and interpret the effects of matter and energy flows at all scales in systems of humanity and nature.


Using emergy, sunlight, fuel, electricity, and human service can be put on a common basis by expressing each of them in the emjoules of solar energy that is required to produce them.

New York p.

Howard T. Odum – Wikipedia

From Wikipedia, the free encyclopedia. Emergy Energy Systems diagama. Tropical Ecology 16 l: Each form is generated by transformation processes in nature and each has a different ability to support work in natural and in human systems. Doubling time Leverage points Limiting factor Negative feedback Positive feedback.

Hall titled Maximum Power.

Kitching claimed that the language was a direct result of working with analogue computers, and reflected odkm electrical engineer’s approach to the problem of system representation: This led him to introduce the concept of “energy of one kind” as a common denominator with the name “energy cost”. The Analysis of a Major Interface, R. Work done at these institutions continues to evolve and propagate the Odum’s concept of emergy. Emergy and ecosystems Self-organization Odum, ; Odum, Aquatic and marine ecosystems Odum et al.

Circuit diagrams were skillfully used to illustrate the dependence of agricultural ecosystems and industrial societies upon fossil fuel subsidies Development of ecological indicators-a methodological framework using compromise programming. Odum continued this work for 26 years until his retirement in Eiagrama energies of higher quality wood, peat, coal, oil, living biomassetc.

Evaluation of the costs and benefits of an environmental management system.

The problem of co-production in environmental accounting by emergy analysis. Academy of Management Reviewv. The unit of emergy past available energy use is the emjoule, as distinguished from joules used for available energy remaining diagraja.

Afterthe emergy methodology continued to develop as the community of scientists expanded and as new applied research into combined systems of humans and nature presented new conceptual and theoretical questions. Environmental space and the prism of sustainability: During this time Odum became aware of the interplay of ecological-energetic and economic forces.


Nelson Michael C. He said that the “human is the biosphere’s programmatic and pragmatic information processor for maximum performance”. Some of his energy models and simulations odm general systems components.

Howard T. Odum

Odum wrote some 15 books and papers, and a Festschrift volume Maximum Power: Nonetheless, they were able to estimate the total flow of energy through the entire system. The difference between input and output, under steady state conditions, was a measure of the metabolism of the whole system.

Emergy, environ, exergy and ecological modelling. That year diagramq moved to the University of Florida, where he taught at the Environmental Engineering Sciences Department, founded and directed the Center for Environmental Policy, and founded the University’s Center for Wetlands in He classified water bodies based on their P-R ratios, this separated autotrophic from heterotrophic ecosystems: Odum said that “when a group gathers around a table to talk about analyzing the main components of a new system or problem, one person can diagram for the group, enhancing the coherence of the discussion.

For example, when the Odums had studied the metabolism of the reef at Eniwetok Atoll, they were not concerned with individual species.
