The theory of power and efficiency in ecology. Effect of hydrologic subsidy on self-organization of a constructed wetland in Central Florida.

It is postulated that there is a natural selection of the possible systems that may form from a given starting condition, and that those systems that result are those which have mechanisms of maintaining stability.

Decision-making tool considering the interaction of the production systems and the environment

Kangas and his student, David Blersch, made significant contributions to the design of the waste water recycling system on the station. The reason that systems can not proceed toward some kind of disintegration is that such a dr has no mechanism of maintaining itself.


Quantifying the environmental support for dilution and abatement of process emissions – The case of electricity production. Work done at these institutions continues to evolve and propagate the Odum’s concept of emergy. Total annual global sources equal to the sum of diagramq 9. The problem of co-production in environmental accounting by emergy analysis.

Howard T. Odum

Emergy and Environmental Decision Making. All energies of higher quality wind, rain, wave, organic dee, wood, fossil fuels, etc. In a controversial move, Odum, together with Richard Pinkerton at the time physicist at the University of Floridawas motivated by Alfred J.

In the s in the latter part of his career H.

Emergy – Wikipedia

Doubling time Leverage points Limiting factor Negative feedback Positive feedback. His general plan “was to characterize the chemostatic flow, to establish diagdama qualitative and quantitative community structureto measure the production rates, and to study the mechanisms by which the community metabolism is self-regulated”. Emergy analysis of municipal wastewater treatment and generation of electricity by digestion of sewage sludge.

Odum over the first thirty years is reviewed in Environmental Accounting [1] and in the volume edited by C. Odum’s contributions to this field have been recognised by the Mars Society. Ecological Engineering18, p.


He classified water bodies based on their P-R ratios, this separated autotrophic from heterotrophic ecosystems: It was the presence of stability which, Odum believed, enabled him to talk about the teleology of such systems. Available on line at: If diagrana postulate is applied to all of nature, the resulting proposition is that nature is as a whole in a steady state or is in the most stable form possible and constitutes one big entity.

To evaluate a system, a system diagram organizes the evaluation and account for energy inputs and outflows. From dizgrama view, biogeochemical cycles are driven by radiant energy. 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.

It is thus postulated that natural selection of natural systems results in the formation of entities defined as above. Academy of Management Reviewv. From Wikipedia, the free encyclopedia. Alexander Bogdanov Russell L.
