Description Water erosion is recognized as a serious long-term threat to the sustainability of soil and water resources in Madagascar. Many factors, both physical and human, make the western slope of Madagascar in general and the Itasy Region in particular, a particularly eroded area. This study focuses on the assessment of soil water erosion in the Lake Itasy watershed by modelling and quantifying it. The empirical model RUSLE (Revised Universal SoilLoss Equation) was used to estimate soil losses, highlighting the contributions of multispectral remote sensing. This method is based on five parameters, including: rainfall erosivity R, soil erodibility K, topography LS, vegetation cover C and anti-erosion practices P. The map of areas at potential risk of soil loss thus obtained is supported by the analysis of multi-date satellite images, contributing to the understanding of the phenomenon of soil water erosion at the catchment scale.
