Análise das condições ambientais no entorno dos sistemas de abastecimento de água da região geográfica imediata de Catolé do Rocha - São Bento, Estado da Paraíba

Abstract

The Brazilian semiarid is characterized by low rainfall and a consequent scarcity of water resources, thus, it is necessary to alleviate the problems caused by long periods of drought, usually through the accumulation of water in artificial reservoirs and the preservation of natural water bodies that supply the population of this locality. In this work, are studied the immediate geographic region of Catolé do Rocha-São Bento, located in the semi-arid state of Paraíba, as a way to identify the environmental conditions of reservoirs and sources of supply for human consumption, through the use and occupation analysis. of the earth around them. In this context, it was necessary to understand the problem caused by environmental degradation, the role of water resources management, and the application of Remote Sensing techniques for environmental analysis. Current images of the OLI-LANDSAT 8 sensor that allowed this study were used, obtaining thematic maps on land occupation as results that were compared and complemented with the environmental diagnoses collected from the field visit. Finally, through the analysis, mitigation proposals were suggested as a way to mitigate the identified environmental and sanitation problems. Thus, it was possible to diagnose the environmental conditions of water supply for the region.
