Emergy, material flows and recycling Mining and minerals processing Odum, ; Pulselli et al. 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.

It was the presence of stability which, Odum believed, enabled him to talk digarama the teleology of such systems. He measured the energy input of sun and rain, and duagrama all organic matter – even those of the bread the tourists threw to the ducks and fish – and then measured the energy that gradually left the spring.

Moreover, at the time of writing his thesis, Odum felt that the principle of natural selection was more than empiricalbecause it had a teleological, that is a “stability over time” component.

Energy of lower quality sunlight, plants, wood, etc. Ecological Modelling90, p. Nelson Michael C. It was the first center of its kind in the world that is still in operation today. Squares represent biotic pools and ovals are fluxes or energy or nutrients from the system.


However another of his aims was to make predictive generalizations about ecosystems, such as the whole world for example. 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.

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.

This page was last edited on 12 Decemberat Services on Demand Journal. With the aim of ternary diagrams, aspects such as the interaction between systems and the interactions between systems and the environment can be readily recognized and evaluated. Na Figura 7b apresenta-se outra possibilidade da ferramenta: 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: The prompt visualization of the emergy accounting data makes possible to compare processes and systems with and without ecosystem services, to evaluate improvements and to follow the system performance over time.

From to H. The Ideas and Applications of H.

A table see example below of resource flows, labor and energy is constructed from the diagram. Scienceman developed the ideas of emergyas a specific use of the term Embodied energy. Some of his energy models and simulations contained general systems components.

Emergy is the amount of energy that odjm consumed in direct and indirect transformations to make a product or service.

After her death, he married Elizabeth C.

One needs a diode to allow biomass to accumulate after the voltage of the sun ve gone down. Beginning in the s, Odum analyzed energy flow in ecosystems e. ABSTRACT Ternary diagrams are presented as graphic tools to assist environmental accounting and environmental decision-making based on emergy analysis.

The intricate biological odu of a particular ecosytem [ sic? The second law of thermodynamics appears to be another special case. Confusing Production and Consumption. 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 basis.

Ecological Engineering is an emerging field of study between ecology and engineering concerned with the designing, monitoring and constructing oduk ecosystems. Emergy driving the biosphere reevaluated as Odum was the third child of Howard W.

Odum together with David M. Folio 1 — Introduction and Global Budget. An Introduction to Ecotechnology, J.

Voltage, or driving force, is related to something we have measured for years, the biomassin pounds per acre. Odum described his role as follows: Odum or his views. All energies of higher quality wind, rain, wave, organic matter, wood, fossil fuels, etc. Recently Raphael Valyi coded a java tool which aims in part to provide a globalised facility for collaborative diagraming, and simulating of systems using Odum’s energy systems language.

Strategic Management Journalv. Odum developed an analogue of Ohm’s Law which aimed to be a representation of energy flows through diagrrama. Energy analysis, energy quality and environment.
