Análise e avaliação ambiental de um trecho da margem do Rio Parnaíba na região Centro norte da cidade de Teresina, Piauí

Abstract

Riparian forests defined as a permanent preservation area (APP's) are essential green areas, as they provide various environmental functions in the environment where they are located. However, these areas are disregarded during the city formation process, as they begin on the banks of rivers, deconstructing the natural setting of this vegetation and causing a series of environmental impacts in the area. Thinking about the benefits of riparian forests in improving urban environmental quality and water resources, this work sought to analyze the environmental impacts present on the right bank of the Parnaíba river in a stretch of the central-north region of Teresina, where the impacts were analyzed and evaluated environmental conditions in six sections of the study area. Data were collected through on-site visits, where at each point the environmental impacts on the physical, biotic and anthropic environments were identified and described.With the analysis, it was identified that its bank suffers mainly from irregular disposal of solid waste and the presence of consolidated areas in a large part of the Parnaíba river bank, which contribute to the reduction of vegetation cover in this area. It is concluded from this research that the banks of the Parnaíba River present different types of anthropogenic occupations, and as a consequence of these occupations they suffer environmental impacts especially associated with irregular deposits of solid waste.
