SUMMARY:

 

Erosion is seen as one of the main threats to soil degradation, food, water and energy security. In rural areas, it has caused concern due to the loss of soil, water, nutrients, reduction of agricultural productivity and degradation of pastures by triggering erosion in furrows, gullies and silting of water bodies. The general objective of this work was to carry out an environmental diagnosis and analyze the vulnerability to soil loss by water erosion in rural areas of the municipality of Rurópolis, Pará. The research was divided into three chapters. The first aimed to identify the temporal evolution of no-tillage as a method of preventing and controlling water erosion in agricultural lands in Brazil. The second chapter presented the physical and environmental characterization of the municipality of Rurópolis, Pará. The third, aimed to identify the areas most vulnerable to soil water erosion in rural areas of the municipality of Rurópolis, Pará. The information was presented in the form of maps and description of each thematic class on climatic conditions, hydrography, relief, pedology, land use and cover and analysis of vulnerability to soil loss by water erosion. The predominant land use in the municipality is extensive livestock farming. It was found that the class of soil loss by water erosion most expressive in territorial extension was the one of medium vulnerability with 3,493.65 km², covering approximately 50% of the study area. In the field, it was observed in areas of pastures with exposed soil, the development of erosion in furrows, gullies and silting of streams. The information generated in this study will contribute to better decision making regarding the ways of using the rural areas of the municipality.
