Uso de sistema de informação geográfica para subsidiar o cálculo de estoque de carbono em florestas no âmbito do mecanismo de desenvolvimento limpo.

Abstract

Increasing expectation for the carbon credit market regulamentation take place as a result of the Kyoto´s Protocol enforcement. In case of credits that come from reforestation or forestation projects, as foresseen under the Clean Development Mechanism (CDM), it is fundamental to establish a methodology for quantification of carbon stocks stored under the vegetal biomass form. This work proposes, as an informatizated method of forests carbon stocks calculation, a set of functionalities and a cadastre data model totally integrated with an open architeture of Geographyc Information System. Based on maps and images georeferenced on data basis provided by small transectos, the system calculates the total amount of carbon storages all over the forest. Besides allowing to present the results to different storing carbon agents, for instance, forests segments or each vegetal species, the system keeps historical register of dendrometrics data, which will make possible the generation of graphs, curves of growth and, therefore, future evaluation.
