A methodological proposal for quantifying environmental compensation through the spatial analysis of vulnerability indicators

摘要

The aim of this work was to propose a methodology for quantifying the environmental compensation through the spatial analysis of vulnerability indicators. A case study was applied for the analysis of sand extraction enterprises, in the region of Descalvado and Analandia, inland of S?o Paulo State, Brazil. Environmental vulnerability scores were attributed for the indicators related to erosion, hydrological resources and biodiversity loss. This methodological proposal allowed analyzing the local alternatives of certain enterprise with the objective of reducing impacts and at the same time reducing the costs of environmental compensation. The application of the methodology significantly reduced the subjectivity degree usually associated to the most of the methodologies of impact evaluation.
