| Sumario: | The Brazilian environmental legislation establishes restrictions of use in some areas in rural properties, to protect relevant spaces for the conservation of species and natural resources. In this respect, geoprocessing has become an essential tool in the monitoring and inspection of areas whose native vegetation must be maintained. The objective of this study was to identify the Permanent Preservation Areas (PPAs) and Legal Reserve (LR) located in the Buranhém River watershed, between the states of Minas Gerais and Bahia, and to verify if these areas meet the requirements of Brazilian law or if there are conflicts in land use. For the mapping of vegetation and APP classes, images from the Sentinel-2 satellite, the digital elevation model (DEM) from Alos-Palsar, and the free program QGIS were used. It was found that in 74.7% of the PPAs and 41.8% of the Legal Reserve areas do not have predominantly native vegetation, what characterizes a legal conflict of use of these areas. Therefore, for rural properties to be regularized, it is necessary to recover these areas that are not in compliance with current legislation. |
