Identificação de conflitos de uso em áreas de APP na APA do Pratigi-Ba

Abstract

The Permanent Preservation Areas (PPAs) in recent years are suffering from the constant degradation due to the increase of anthropogenic activity intensified on these areas. The aim of this study was to identify conflicts of use in the PPAs through maps and tables. The study was done with the area of Apa Pratigi, south of Bahia, that has a size of 1700 km2 ha. The hypsometry maps and slope were made with the SRTM (Shuttle Radar Thematic Mapper) 30 meters and ArcGIS software. The SRTM was used to do the PPAs map, and it was made with the term of the Forest Code. The total area of the PPAs APA Pratigi, was 345,88 km2, about 20.22% of the total area. The calculation of conflict areas was done after the overlap between the PPAs map and land use map. One of the classes that had higher values within this overlap was the forest remnants, which obtained 39.43% of the PPAs. In addition, it was also possible to identify 46.61% of all APPs are consolidated areas. In this context it is necessary to suitability of the consolidated areas which determines the new Forest Code in relation to the PPAs.
