Caractérisation des aménagements de lutte contre la désertification moyennant l’outil Géo-informatique Global des Options par Contexte : Cas du transect Dhahar-Béni Khédache-Jeffara (gouvernorat de Médenine)

Abstract

Monitoring and evaluation of sustainable land management practices to achieve land degradation neutrality has become one of the priorities in the countries signatories of the UN Convention to Combat Desertification. This study aims to test the Ge OC tool, currently under development, on the combat desertification actions in the transect Dhahar-Béni Khédache-Jeffara. It is essentially based on bibliographic analysis, local and international expertise, and global databases, in a GIS and Web framework. The majority of water and soil conservation techniques as well as wind erosion control techniques have been inventoried and characterized in some different biophysical and socioeconomic

contexts of the study area. In addition, preliminary results on the impacts of the developments made have been obtained. Once calibrated and validated, this tool could be a decision support tool for sustainable land management in areas threatened by desertification
