One of the main problems affecting the watersheds of the Peruvian highlands is water erosion of their soils, especially in areas with steep slopes. The main climatic factor influencing water erosion is precipitation, which affects the headwaters of river basins with greater intensity. Hence, soil erosion not only causes the loss of soil on slopes, but also the loss of fertility and low productivity of crops, pastures and forage; therefore, the evaluation of the risk of water erosion is essential to promote conservation strategies. The Revised Universal Soil Loss Equation (RUSLE) was used to estimate the annual soil loss in the Aguaquirí river basin, with the support of cartographic and satellite information of the area, and Geographic Information System (GIS) tools. Using programs such as QGIS 3.22, SAGA-GIS and RStudio, as useful tools for the analysis and geoprocessing of the RUSLE equation factors, it was possible to identify the priority areas in the basin most affected by water erosion according to the FAO classification, the result of which was captured in a thematic map showing the various levels of water erosion. As a result, the largest surface area in the basin is occupied by soils affected by "High Erosion" (from 50 to 200 t/ha/year), extending over 4885.494 hectares (53.68% of the study area), concentrated in the middle and upper part of the basin; also calculating an average annual water erosion rate of 93.73 t/ha/year. Furthermore, based on the resulting erosion map, the implementation of soil conservation practices was proposed, prioritizing those areas with steep to extremely steep slopes, in order to reduce the erosion rate present in the watershed.
