Impactos ambientais na bacia hidrográfica do rio Portinho, norte do Piauí

Abstract

The hydrographic basin of the Portinho River is a coastal basin located in the northern region of the state of Piauí, comprising the municipalities of Parnaíba, Luis Correia, Buriti dos Lopes and Bom Princípio do Piauí. The area has a great socioeconomic and landscape value, however, it has undergone several anthropic interventions such as urban expansion, agriculture and unplanned tourism. In view of the relevance of the facts involved, this study aimed to identify the main anthropic activities and their effects on the Portinho River basin, mapping the most affected areas. The studies were carried out from field research and bibliographical, cartographic and documentary surveys, with the aid of geoprocessing techniques for mapping of the area. The results of the research indicate an intensification of use and occupation of the area of the studied basin, culminating in changes in the local landscape and socioenvironmental losses
