Análise Multicritério aplicada ao mapeamento de risco de incêndio na APA Sul RMBH

Abstract

Burns are a threat to the conservation of ecosystems, especially in Conservation Units, territories of great value considering their physical and biotic attributes, which can result in significant and lasting impacts from an ecologicalanda social and economic point of view. The objective of this work was to map areas susceptible to fire risk in APA Sul RMBH using geoprocessing techniques. Multicriteria analysis was used by the Hierarchical Process Analysis (AHP) model considering secondary data regarding the physiographic and socioeconomic characteristics of the study area. The resulting map, with the areas with the highest risk of fire occurrence, indicated a predominance of medium risk throughout the APA Sul, with the high-risk areas concentrated in places with the lowest elevations in the cutout, flatter slopes, in pastures and agricultural mosaics, intermediate precipitation and temperature regimes. In contrast,areas less prone to fires are located in rocky outcrops, high altimetry, mountainous to steep slopes and away from the main localities and roadways. It is believed that the use of geotechnologies for this purpose can subsidize the planning and management of this important conservation unit.
