Mapeamento geoambiental do meio biofísico da área da cidade e entorno de Taperoá – Ba – Brasil.

Abstract

The exploitation of natural resources, population and urban growth, as well as the creation of the National Environmental Policy Law in the early 1980s and its subsequent guidelines, were factors that drove a great advance in prevention techniques over the years and control of impacts and preservation of the environment. These advances are relevant in land use and land planning. In this sense, this work aims to map the biophysical environment of the area of ​​the city of Taperoá and its surroundings, a coastal area in the southern part of the State of Bahia, which has undergone intense degradation, due to the advance of the urban area towards areas of greater environmental susceptibility , such as mangrove areas, flood plains and coastal plains. The study was developed in three stages: i) the acquisition of remote sensing images, for the extraction of information from the terrain through geoprocessing procedures in a GIS (Geographic information systems) environment; ii) the field campaign phase, with collection of data and information from the physical environment, in addition to the identification of potentially polluting sources; iii) thematic maps of geology, geomorphology, vegetation, land use and occupation and protected areas. From the integration of data and information from these maps, 7 geoenvironmental units were delimited in the studied area, from which it was possible to indicate the areas of greatest environmental susceptibility, the potentialities, limitations and restrictions of each unit.
