Soil erosion is a critical risk facing the environmental and economic sustainability of agricultural land systems. It is considered among the most important problems that threaten ecosystems in the Syrian coastal region. This work aims to evaluate the spatial distribution of soil erosion risk in the Ghamima River Basin, especially in light of the lack of necessary data. For that purpose, the revised universal soil loss equation (RUSLE) model integrated with the geographic information system (GIS) and remote sensing (RS) data were used to formulate optimal soil erosion management plans and assess erosion risk levels. The results showed that the soil loss rate in the Ghamima River Basin ranges between 0 - 60 tons ha-1 year-1. The resulting soil erosion risk map was created and classified into five risk levels: very low (47.31%), low (28.38%), medium (12.61%), high (6.39%) and very high (5.31%). It was found that 11.7% of the lands of the study area are exposed to a high and very high degree of soil erosion risk. Accordingly, these results can be relied upon to support decision-makers in taking measures to mitigate the negative effects of soil erosion risk and designing soil protection strategies to prevent acceleration of erosion in high and very high-risk areas.
