Panorama da mata ciliar do rio Piauí no perímetro urbano da Cidade de São João do Piauí

Abstract

Riparian forests are important for maintaining rivers, lakes and other bodies of water. They protect the banks of water bodies from erosion and sediment deposits in the riverbed. With this in mind, this study sought to identify the degradation of the riparian forest of the Piauí River, on the urban perimeter of the city of São João do Piauí, in the year 2024. To this end, bibliographical, documentary and field research was carried out, and geoprocessing software was used to create thematic maps of the study area. It was found that the riparian forest in the study area has been greatly altered by anthropic action. Socio-environmental impacts such as deforestation, erosion, sand extraction from the riverbed, pollution, farming activities and irregular occupations were identified, leading to various environmental impacts on the river and its ecosystem. Therefore, this study hopes to have corroborated the geoprocessing and field data so that the government can take steps to recover and preserve the area. Furthermore, this work can help with future projects and studies in the area, and inform the population about the current state of the river and the consequences that could occur if the appropriate measures are not taken.
