He was the younger brother of Eugene Odum.

The Ideas and Applications of H. Jackson Alexander Christakis Kenneth D. Environmental space and the prism of sustainability: Odum or his views. Ecosystem ecology and Systems ecology. Odum looked at natural systems as having been formed by the use of various forms of energy in the past: This approach represented the migration of cybernetic ideas into ecology and led to the formulation of systems ecology.

Energy analysis, energy quality and environment. Emergy, material flows and recycling Mining and minerals processing Odum, ; Pulselli et al. Doagrama is one of his most important contributions to the beginnings of the field of ecological engineering. InOdum married Virginia Wood; they had two children together.

Fossil fuels and then coal the baseline. Zoologymeteorologyecology and systems ecology.

Odum in [46] well before he worked at the University of Florida. Development of ecological indicators-a methodological framework using compromise programming. Production and operation management: Emergy analysis of municipal wastewater treatment and generation of electricity by digestion of sewage sludge.


Lotka ‘s articles on the energetics of evolution, and subsequently proposed the theory that natural systems tend to operate at an efficiency that produces the maximum power output, not the maximum efficiency. For Odum, as a large entity, the world constituted a revolving cycle with high stability.

Emergy – Wikipedia

He said that the “human is the biosphere’s programmatic and pragmatic information processor for maximum performance”. As soon as it does the system fits the definition of an entity. Circuit diagrams were skillfully used to illustrate the dependence of agricultural ecosystems and industrial societies upon diagrmaa fuel subsidies Emergy accounting converts the thermodynamic basis of all forms of energy, resources and human services into equivalents of a single form of energy, usually solar.

Odum arrived at the concept he termed hierarchical organization.

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

He classified water bodies based on their P-R ratios, this separated autotrophic from heterotrophic ecosystems: Emergy and Environmental Decision Making. The only higher education institute to award honorary degrees to both Odum brothers was The Ohio State University, which honored H. However another of his aims was to make predictive generalizations about ecosystems, such as the whole world for example.

Kangas noted that Odum first set out the theory that Ohm’s Law from electronics was analogous to the thermodynamic functioning of ecosystemsp. Besides the unquestionable advantages of graphic interpretation over table analysis, the use of ternary diagrams, widely used for physical chemistry evaluation of three components systems, or three components phase diagrams, permits the use of phase diagrams properties to assess the dependence of the system upon renewable and non renewable inputs, the environmental support for dilution and abatement of process emissions and the system efficiency.


Howard T. Odum

The concept of emergy has been controversial within academe including ecology, thermodynamics and economy. Total annual global sources equal to the sum diiagrama these 9. Self organization and maximum power. Comparative studies of the metabolism of Texas Bays.

Emergy analysis perspectives of Thailand and Mekong River dam proposals. Odum was also honored by the journal Ecological Engineering [54] for his contributions to the field of ecological engineering and ecology in general ds recognition of his 70th birthday.

Another purpose is to seek the best use of resources to maximize economic vitality. The maturing of the emergy methodology resulted in more rigorous definitions of terms and nomenclature and refinement of the methods of calculating transformities. Academy of Management Reviewv.

Howard wrote the chapter on energeticswhich introduced his energy circuit language.
