Avaliação da perda de biodiversidade decorrente da transformação do uso da terra da floresta amazônica para lavoura de soja

Abstract

The land use transformation in the Amazon forest to pasture or soy crop, decreases the rainfall due to the change of albedo and this decrease in the precipitation conditions the vegetation, taking to the loss of species most sensitive to water stress. Trough Life Cycle Impact Assessment (LCIA), one of the stage of the Life Cycle Assessment (LCA), the results of the previous stage (Life Cycle Inventory - LCI) are converted into impacts, aiming a better understanding at the environmental significance. The biodiversity loss assessment is still very limited in LCA studies, but, in the Brazilian case, it was identified the possibility of assessing the biodiversity depending on rainfall, who change can be assessed based on the conversion of land use. The goal of this study was to propose a model to characterize loss of biodiversity resulting from changes in the land use. More specifically, from Amazon forest to soy crop. The characterization factors were calculated, and finally, suggestions were made for future improvements of the model and its adaptation for other types of land use transformation.
