Avaliação dos impactos ambientais no rio Vieira, Montes Claros - MG

Abstract

The Vieira River is located entirely in the municipality of Montes Claros/MG. The city occupies a large part of the territorial extension of the river's hydrographic basin, so the present study aimed to carry out an environmental diagnosis of the Vieira river's hydrographic basin, indicating the main environmental impacts. A map of land use and occupation generated using the Qgis free software, and on-site visits were carried out, in two different periods, dry and rainy, for the diagnosis of environmental impacts. The results obtained through the preparation of the land use and occupation map of the Vieira River watershed, it was found that in 2019 the natural vegetation occupies more than half of the basin, however with the diagnosis of environmental impacts with on-site visits showing which these are impacts through the application of the checklist methodology shows that a large part of the use and occupation of the soil is inadequate due to the presence of solid residues, extensive use of livestock and soils exposed to advanced erosion processes. Thus, the combination of data obtained through the use of geotechnologies associated with fieldwork such as the checklist promote public policies aimed at environmental preservation and sustainable development that will provide the future for the next generations.
