Abstract

The new Brazil’s Forest Code (Law n.° 12.651 of 25 May 2012) established the concept of areas with restricted use (AUR – acronym of the name of that concept in Portuguese), described as slopes between 25° and 45°, where agro-environmental activities can be developed. Thus, the objective of this study was to develop a methodology for delimiting AUR based on slope, with a case study for the municipality of Capelinha, in mesoregion of Vale do Jequitinhonha, state of Minas Gerais, Brazil. The mapping was carried out with the support of geoprocessing tools, using digital elevation models (DEM). After the hydrologically consistent DEM (HCDEM) was generated, the method applied for generating AUR was based on the following steps: generation of the terrain slope in raster format; segregation of areas with slopes between 25° and 45°; reclassification into a new raster; conversion to shapefile; elimination of features with slopes <25° and >45°; and generation of the final map and calculation of the AUR. Due to its ease of replication, the methodology can be fundamental in the development of territorial and environmental planning strategies, since these areas require greater attention in terms of environmental planning due to erosive processes associated with the slope factor. Thus, this methodology can work as a mechanism for managing areas and conducting environmental inspections at the municipal level.
