Resumo
The study presents a method-proposal for determining priority areas for recovery (APR) in the Pequia stream watershed (BHCP), considering its sub-basins, through Geoprocessing. Data from the Universal Soil Loss Equation (USLE), Land Surface Temperature (TST) and Normalized Difference Vegetation Index (NDVI) were evaluated. In the APR prioritizing, morphometric indices and variables of the Water Quality Index (IQA) through Analytic Hierarchy Process (AHP) were considered. Almost 90% of the APP in one of the sub-basins are deforested. All the sub-basins presented very high soil loss. The remaining forest presented NDVI suitable for the biome. The Brejio and Moquito sub-basins had the highest priority for APR. The method is adequate and important for territorial management, as it allows spatial environmental analysis and for the use of free data and software.
