The inevitable changes in land management systems are driven by the challenges of the population explosion and climate change facing the Drâa-Tafilalet region. At the same time, natural and human processes are having an impact on the capacity of production systems. As a result, the degradation of natural resources is expected in many regions, as is the loss of land productivity and biodiversity, which has already occurred in the Ziz basin. The resulting soil vulnerability map should reveal homogeneous zones for priority intervention. The aim of our work is to assess the influence of watershed characteristics on the vulnerability of the Ziz basin. To this end, an analysis is carried out to complement the field surveys, and a computerized and logical methodology is presented. We have identified the factors that determine soil vulnerability. And to combine these different factors, we used a partition space made up of regular grid cells.
