Resumo: Deforestation in the Amazon Rainforest is a recurring theme on the national and international environmental agenda. However, little attention has been given to its influence on water erosion and soil degradation. This study aimed to model the effect of deforestation on the spatial and temporal variation of water erosion in a watershed of the Amazon region. Therefore, we hypothesize that the expansion of deforestation, and the consequent changes in land use and cover, contributed to increasing soil losses due to water erosion. The Xingu River watershed was selected as a study area once it is one of the most affected regions by deforestation in the Brazilian Amazon. The estimate of water erosion was performed in the years 1988, 1998, 2008, and 2018 using the Potential Erosion Method (EPM). The application of the model was carried out in a Geographic Information System environment. Between 1988 and 2018, the deforestation in the selected basin increased by 12% (52,258 km2 ). In the same period, water erosion increased by 312%, corresponding to about 180 million tons of soil lost per year. The result of the study can help in planning erosion control in the Amazon region.

Este estudo objetivou modelar o efeito do desmatamento sobre a variação espacial e temporal da erosão hídrica na região Amazônica. Nossa hipótese é que a expansão do desmatamento e as consequentes mudanças no uso e cobertura da terra, contribuíram para aumentar as perdas de solo pela erosão hídrica. A Bacia Hidrográfica do Rio Xingu foi selecionada como área de estudo por ser uma das regiões mais afetadas pelo desmatamento na Amazônia Brasileira. A estimativa da erosão hídrica foi realizada nos anos de 1988, 1998, 2008 e 2018 utilizando o Método de Erosão Potencial (EPM). A aplicação do modelo foi realizada em ambiente de Sistema de Informação Geográfica. Entre 1988-2018, ocorreu um aumento de 12% (52.258 km2) no desmatamento da floresta amazônica da bacia. No mesmo período houve um crescimento na erosão hídrica em 312% correspondente a cerca de 180 milhões de toneladas de solo perdido por ano. O resultado do estudo pode auxiliar no planejamento de controle da erosão na região amazônica.Universidade Federal Rural de Pernambuco2021-09-14T19:02:19Z2021-09-14T19:02:19Z2021-03info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfLENSE, G.
