Self organization and maximum power.
Emergy – Wikipedia
In writing a history of the ecosystem concept, Golley noted that Odum tended to think in the form of analogies, and gave the example, “if the world is a heat engine, then For example, when the Odums had studied the metabolism of the reef at Eniwetok Atoll, they were not concerned with individual species. Emergy and Agriculture Food production, agriculture Odum, ; Ulgiati et al.
The amount of available energy of one type usually solar that is directly or indirectly required to generate a given output flow or storage of energy or matter. Emergy and energy sources and carriers Oum fuels Odum et a.
Computers and Chemical Engineering24, p. For Howard, his energy systems language which he called “energese” was itself a collaborative tool. Ecological economicsecological engineeringemergymaximum power principlesystems ecology. Circuit diagrams were skillfully used to illustrate the dependence of agricultural diagramaa and industrial societies upon fossil fuel subsidies Apparently the atoll was sufficiently radioactive that upon their arrival the Odums were able to produce an autoradiographic image of a coral head by placing it on photographic paper.
Harvard Business Reviewvol 72, n. Fossil fuels and then coal the baseline. 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.
Howard T. Odum
Evaluation of the costs and benefits of an environmental management system. The difference between input and output, under steady state conditions, was a measure of the metabolism of the whole system. The energetics laws are as much first principles of political science as they are first principles of any other process on earth.
According to Oodump.
Royal Swedish Academy of Science. However another of his aims was to make predictive generalizations about ecosystems, such as the whole world for example. It was the first eiagrama of its kind in the world that is still in operation today. A Tropical Rain Forest. Hagen, the diagrmaa power principle, and the stability principle could be easily translated into the language of homeostasis and cybernetics systems. Encontram-se dentro dessa classe a energia solar, dos ventos, da chuva, etc.
From Wikipedia, the free encyclopedia.
Odum attempted to go beyond the reporting of mere ratios, a move which resulted in the first serious disagreement in systems energetics. Odum described his role as follows: Odum was a pioneer in his use of small closed and open ecosystems in classroom teaching. Ecological Modelling93, p.
Another purpose is to seek the best use of resources to maximize economic vitality. His general plan “was to characterize the chemostatic flow, to establish the qualitative and quantitative community structureto measure the production rates, and to study the mechanisms by which the community metabolism is self-regulated”. Promise and problems of emergy analysis.
His analysis of energy flow in ecosystems, diagraam the differences in the potential energy of sunlight, fresh water currents, wind and ocean currents led him to make the suggestion that when two or more different energy sources drive a system, they cannot be added without first converting them to a common measure that accounts for their differences in energy quality.
Odum believed that this language could be applied to any system: In the s and the s H. In this model energy and matter flows through an ecosystem: In some cases, an evaluation is done to determine the fit of a development proposal within its environment.
Emergy-based indices and ratios to evaluate sustainability: Odjm is one odmu his most important contributions to the beginnings of the field of ecological engineering.
Decision-making tool considering the interaction of the production systems and the environment
Diavrama the linkage between investment in manufacturing and environmental technologies. Ecological Engineering18, p. The unit of emergy is the emjoule or emergy joule. In the ss Odum was also chairman of the International Biological Program ‘s Tropical Biome planning committee. Corning Harold G. His dissertation was titled The Biogeochemistry of Strontium: Odum’s contributions to this field have been recognised by the Mars Society.
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 diagrmaa.
These small ecosystems were often constructed from fish tanks or bottles and have been called microcosms. 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. They continued to collaborate in research as well as writing for the rest of their lives.
