ABSTRACT:Desertification is the gradual and sustained reduction in the quantity and quality of the biological productivity of arid and semi-arid land. The study area is located in the North Eastern part of Algeria, it has a rich heritage in its biodiversity, however weather conditions and adverse human reality, induce a degradation of the physical environment in the form of a regression of vegetation cover. To assess desertification in our study area map of desertification sensitivity is a tool for decision support. For the realization of this Map we used the ArcGis software applied a methodology which is inspired by the concept MEDALUS (Mediterranean Desertification and Land Use, 1999) by crossing four thematic layers that may have an impact on the process of desertification. The results of Cartography and statistical analysis permit the classification of our region in terms of sensitivity to desertification in four very important classes. (Not affected, Insensitive, Sensitive and highly sensitive). More than 69.92% of the surface area were classified sensitive to very sensitive, For against 30.07% is classified in unallocated insensitive. Planning restoration work and the fight against desertification are expected to limit the risk of desertification in the study area perspectives.

Risk cartography is a primordial step for the valuation and management of desertification process but it is a complicated one, which necessitates large amounts of spatial and statistical data. The use of Geographic Information Systems (GIS) permits to manage and use these data efficiently. The objective of our study was the compilation of desertification sensitivity maps of the area south of Aurès region, Algeria. We used a GIS system following the MEDALUS methodology (Mediterranean Desertification and Land Use), which use qualitative indices to define zones sensitive to desertification. The creation of the database consists of four information layers (soil, vegetation, climate and the socio-economic data) accomplished with ground validation. Once the database was completed, its elaboration helped identifying sensitivity areas through the use of various indices. The result is a middle scale risk map, which presents a synthesis of the desertification intensity. The map is an efficient tool to help decision makers endorse sustainable land management strategies for the protection of natural resources, especially to those greatly affected by increased aridity.
