Effect of hydrologic subsidy on self-organization of a constructed wetland in Central Florida. This article is about the American ecologist. Odum together with David M. The unit of emergy past available energy use is the emjoule, as distinguished from joules used for available energy remaining now. Hence Odum also had the aim of extending the scope and generality of natural selection, to include large entities such as the world.

Odum and Howard T. Na Figura 7b apresenta-se outra possibilidade da ferramenta: Landscape and Urban Planning63, odhm. It was the first center of its kind in the world that is still in operation today.

Villas Boas de Almeida; Biagio F. Several ratios, or indices are given in Figure 2 that assess the global performance of a process.

In Odum’s work these concepts form part of viagrama Hagen called an, “ambitious and idiosyncratic attempt to create a universal science of systems” Ibid. Views Read Edit View history.

Emergy and systems modeling Energy systems language and modeling Odum, ; Odum, National sustainability Brown et al. Odum viewed humans as playing a central role: The second, revised edition of his major lifework was retitled Ecological and General Systems: In the s Odum introduced his electrical circuit diagrams of ecosystems to the Ecological Society of America.

The doagrama to do work for man depends on the energy quality and quantity and this is measurable by the amount of energy of a lower quality grade required to develop the higher grade. It is thus postulated that natural selection of natural diagramq results in the formation of entities defined as above. This approach represented the migration of cybernetic ideas into ecology and led to the formulation of systems ecology.

Folio 1 — Introduction and Global Budget. Further to this Odum also mooted two more additional thermodynamic laws see Energeticsbut there is far from consensus in the scientific community about these proposals, and many scientists have never heard of H.

Ecological engineering, he wrote, is “those cases where the energy supplied by man is small relative to the natural sources but sufficient to produce large effects in the resulting patterns and processes. During this time Odum became aware of the interplay of ecological-energetic and economic forces. Emergy and Agriculture Food production, agriculture Odum, ; Ulgiati et al.

Odum arrived at the concept he termed hierarchical organization.

Exactly what this is in nature is still uncertain, as it is a new concept. Strategic Management Journalv. Global solar energy the baseline.

Howard T. Odum

However another of his aims was to make predictive generalizations about ecosystems, such as the whole world for example. The term ” embodied energy ” was used for a time in the early s to refer to energy quality differences in terms of their costs of generation, and a ratio called a “quality factor” for the calories or joules of one kind of energy required to make those of another.

Work done at these institutions continues to evolve and propagate the Odum’s concept of emergy. Odum developed an analogue of Ohm’s Law which aimed to be a representation of energy flows through ecosystems. Indeed, at the time they were unable to identify them.

Howard T. Odum – Wikipedia

Around Odum directed studies into radioecology [26] which included the effects of radiation on the tropical rainforest at El Verde, Puerto Rico Odum and Pidgeonand the coral reefs and doum ecology at Eniwetok atoll.

Another purpose is to seek the best use of resources to maximize economic vitality.

Kitching claimed that the language was a direct result of working with analogue computers, and reflected an electrical engineer’s approach to the problem of system representation: This was one of the first projects to explore the now widespread approach of using wetlands as water quality improvement ecosystems.

While at Yale, Howard began his lifelong collaborations with his brother Eugene. This is one of his most important contributions to the beginnings of the field of ecological engineering. Linhas de Fontes de Recursos:
