Geotechnologies in the mapping of environmental fragility

The present work is focused on the study of the Areas of Permanent Preservation (APP's) and Land Use and Occupation of the Watershed Ribeir o Periquito, which is part of the drainage network of the municipality of Selv ria in the state of Mato Grosso do Sul, which is a tributary of the Rio Sucuri on its left bank composing an important hydrographic region in the state of Mato Grosso do Sul, formed by the Rio Paran to the east, Rio Verde to the south and Rio Quit ria to the north. The Watershed of Ribeir o Periquito is located between the geographical coordinates 20 32' 12" S, 51 36' 34" W and 20 22' 37" S, 51 45' 6" W. The study is directed towards the evaluation of the respective areas of permanent preservation, possible changes in their dynamics, consistent with the forms of occupation of this region, whether by forestry or livestock. Therefore, the studied environment will be structured in the following way: the Watershed of the Ribeir o Periquito River and a component part of the Subsystem Sucuri River Watershed, which has the Paran River Watershed as its System.
