From Exergy to Economy: a transdiciplinary approach to sustainability of ecosystems: a synthesis

Da Exergia para a Economia: abordagem transdisciplinar para a sustentabilidade dos ecossistemas: uma síntese

Exergy is the amount of energy that produce genes and infornmation. To be away from the thermodynamic equilibrium, find in detritus, the exergy of an ecosystem, represents the accumulation of information. Higher exergy levels,means higher buffer capacity and a measure of ecosystem health. The ability of an ecosystem to resist perturbation represents a high exergy level, and results in stability. To be away from the thermodynamic equilibrium, means more growth capacity of an ecosystem, more stability, increased information, increased network. Growth of physical strucrture growth of complexity of network, growth of information results in stability and less entropy. More stability means more and diverse ecosystems services and as a result better economical performance of the ecosystems. Therefore exergy and economy are conected througouth ecosystem stability and buffer capacity. Therefore it pays for the economy to preserve ecosystem structure and function.
