Geography and Environmental Studies

The urbanization process of Brazilian cities has generated several environmental problems, including occupations and irregular uses in Permanent Preservation Areas (PPA). Land use in marginal strips, coupled with vegetation removal, causes environmental degradation, causing instability of ecosystems. For this reason, the present study aims to identify and analyze land use and land occupation conflicts in PPA localized in the urban perimeter of the municipality of Candelária, Rio Grande do Sul, Brazil. The methodology uses geographic and statistical data from the Brazilian Institute of Geography and Statistics (IBGE) and spactial bases provided by the municipal government. Data systematization and maps elaboration were performed in Geographic Information System (GIS) platform. Candelária presents streams that cut the urban mesh and flow into the Pardo River, thus, there are PPAs of considerable size within the urban area. Research shows that there are improper uses in PPA, such as buildings, irregular settlements and agricultural crops. Finally, the results indicate there is significant area under protection in the city being impacted by human action, aggravating the reduction of native forest.
