ENVIRONMENTAL ASSESSMENT OF THE PERMANENT PRESERVATION AREA ALONG THE IGARAPÉ SANTOS LOCATED IN THE CITY OF TUCURUÍ – PA

Abstract

Industrialization has caused major changes in cities, especially the disordered occupation near water courses. These occupations directly affect the Permanent Preservation Areas (APP) generating negative consequences for the environment and for the local population. The objective of this research is to evaluate the environmental conditions of the Igarapé Santos’ APP, located in the municipality of Tucuruí, PA, Brazil, verifying the specifications and compliances related to the environmental laws and regulations in force regarding the process of expansion and urban occupation. The method used for this work is the deductive one, where the consultation of environmental laws and regulations at the Federal, State and Municipal levels, in addition to articles, books and similar studies, began. Subsequently, visits, photographic records, and visual evaluations of the APP and the riverbed of the igarapé were carried out at points accessible to Igarapé Santos. Finally, using the QGIS software version 3.16.8 and using the Quick Map Services tool to obtain images through Google Satellite for the elaboration of thematic maps and the "Buffer" tool to trace the polygon delimiting the APP range. In this way, it was possible to observe that the urban area of the APP is more degraded than the rural area due to the presence of old and new buildings in the APP, the release of raw sewage and solid waste in the riverbed and on the banks of the Igarapé Santos, and eutrophication. Therefore, the urban area suffers greater environmental degradation caused by disordered occupation and lack of urban infrastructure, compromising Igarapé Santos and the population's quality of life.
