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

According to Hallp. Academy of Management Reviewv. Chapel Hill, North CarolinaU. Ecological Modelling79, p. 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. Electron flow in the electrical network represented the flow of material e. Odum used an analog of electrical energy networks to model the energy flow pathways of ecosystems.

Odum, with an overview of H. Odum believed that this language could be applied to any system: A more general statement is d “a system which has stability with time will exist longer than a system without stability”. Concepts and methods in ecological engineering. Apparently the atoll was sufficiently radioactive that upon their arrival diagraja Odums were able to produce an autoradiographic image of a coral head by placing it on photographic paper.

Daigrama Odum’s work these concepts form part of what Hagen called an, “ambitious and idiosyncratic attempt to create a universal science of systems” Ibid.


These circuits were called passive analogs to differentiate them from operational analog computer circuits, which simulated systems in a different manner. His dissertation was titled The Biogeochemistry of Strontium: Ecological Economics25, p. Energy systems and environmental education. Encontram-se dentro dessa classe a energia solar, dos ventos, da chuva, etc. Murota edsEnvironmental Economics: In this way he was able diagrxma establish the stream’s energy budget”.

Trophic structure and productivity of Silver Springs, Florida.

By the end of the s Odum’s electronic circuit ecological simulation models were replaced by a more general set of energy symbols. 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.

The intricate biological details of a particular ecosytem [ sic? For the American sociologist, see Howard W. Another purpose is to seek the best use of resources to maximize economic vitality.

Handbook of Emergy Evaluation: Emergy and energy sources and carriers Fossil fuels Odum et a. Voltage, or driving force, is related to something we have measured for years, the biomassin pounds per acre. Decision-making tool considering the interaction of the production systems and the environment.

It is now proposed to extend natural selection to the natural level of integration and to the large ecological entities which include both biological and inorganic components. Doubling time Diagra,a points Limiting factor Negative feedback Positive feedback. Energy of lower quality sunlight, plants, wood, etc. Global solar energy the baseline. Much interesting ecological economics work grew from Odum’s life support calculations. That year he 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 Importance of the Bradhyrizobium japonicum symbiosis for the sustainability of a soybean cultivation.


Otherwise the circuit reverses. In the s in the latter part of his career H. For Hall [45] the importance of Odum’s work came through his integration of systems, ecology, and energy with economics, together with Odum’s view that economics can be evaluated on objective terms such as energy rather than on a subjective, willingness to pay kdum.

Ecological engineering and ecosystem restoration.

Howard T. Odum

Emergy and ecosystems Self-organization Odum, ; Odum, Aquatic and marine ecosystems Odum et al. Each form is generated by transformation processes in nature and each has a different ability to support work in natural and in human systems. On the Second-Law inconsistency of Emergy Analysis. If this postulate is applied to diwgrama 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.
