Multicriteria analysis in the definition of priority areas for forest conservation in são félix do xingu – pa

Abstract

The municipality of São Félix do Xingu is part of the development program of the Amazon region, with emphasis on large deforestation caused by activities such as cattle ranching and agriculture, as well as other threats such as settlements and highways. These modifications of extensive areas of forests turn out to be a natural landscape interfering in the maintenance of the biodiversity. In this way, it was objectified through a series of reflections on the priority areas for the forest storage in a region of the municipality of São Félix do Xingu-PA. The study comprised a multicriterial analysis, in which it used the Hierarchical Analytical Process Method (AHP); and, as a way of helping to define the criteria, the principles of the Systematic Conservation Method (SCM) were used. The comparative results were those that showed the greatest influence in the prioritization of plots with a greater number of Permanent Preservation Areas (PPAs), size of fragments, forest fragments with more Legal Reserve Areas (LRAs), settlements / roads, connectivity and phytogeomorphological units, respectively.
