| Resumo: | Permanent Preservation Areas (APPs) are places that can be covered or not by vegetation with
the main functions of: preserving water resources, landscape, geological stability, biodiversity
in addition to ensuring the well-being of human populations. Despite the existence of extensive
and complete regulations addressing APPs, there is still a lack of public environmental planning
policies aimed at controlling and balancing the anthropic environment and the natural
environment. Thus, with the use of geoprocessing techniques and the help of Geographic
Information Systems (GIS), this research carried out a systemic survey in the Permanent
Preservation Areas present in the Pirangi River sub-basin/RN, one of the main sources that
supply the municipality of Natal. The main objectives were: quantification, analysis and
identification of the existence of Land Use and Occupancy conflicts in the place. The
methodology used to obtain the results was first summarized in the characterization of the
environmental parameters of the study area, followed by the creation of a georeferenced digital
database containing: vector data in shapefile format, digital models of terrain elevation and
images from the sentinel satellite -two. Then, in possession of the digital data, using the
technique of visual mapping on the screen of satellite images, the following secondary data
were generated: Land Use and Occupation, delimitation of the APPs of the study site,
delimitation of the terrain slope and the compilation of existing agricultural properties in the
place, it is worth mentioning that, as a guiding object, the Brazilian Forest Code was used,
which discusses the rules for these areas. Finally, the secondary data obtained was merged. The
results showed that, in the region, the occupation of APPs by agricultural activities corresponds
to 27.47% of the total of these. In this way, it is concluded that, in fact, in the region, what is
recommended by law is not followed and supervised in the way it should, causing, due to this,
a great impact in the region. |
