Abstract
Water and soil are two essential natural resources, which their preservation determines the local and national environmental sustainability. The pollution and erosion processes causing deterioration of these resources, which impacting negativaly the environment and economy development. This research aims to suggest the most straight forward and most appropriate control measures for the basins that are socially and economically acceptable for farmers. By consdering Argana basin as study area, the proposed approach consists, first, to analyze the soil loss map and, then, cconducted semi-structured interviews with local farmers at various locations across the basin. The results indicate that the areas of high and very high deterioration encompass 48 % of the basin’s surface. In addition, all of the farmers questioned used agroforestry on their managed sites. The study highlight the importtance of the traditional practices in fighting water erosion risk.

In Mediterranean countries, soil erosion due to rainfall and runoff is a wide spread phenomenon
Watershed management and the management of the implications of soil degradation are gaining a lot of interest from policymakers, especially, for the most degraded regions
Integrating erosion mapping and erosion risk management into a GIS creates a comprehensive tool for directing land-use decisions
Summary
In Mediterranean countries, soil erosion due to rainfall and runoff is a wide spread phenomenon. The Abdelmoumen dam supplies drinking water to the broader Agadir region (9.5 Mm3) and irrigation for the Issen periphery (13,000 hectares). This dam is undergoing rapid siltation, with a specific degradation of 646.15 tons/km2/year [5]. Watershed management and the management of the implications of soil degradation are gaining a lot of interest from policymakers, especially, for the most degraded regions.
