In recent years, the topic of desertification has been discussed in different ways in scientific areas. This event occurred globally, regionally and nationally and many steps were taken to stop it. Desertification is challenged universally and its destructive effects are unavoidable and its consequences do endanger the life of inhabitants. The identification of sensitive regions and prevention and avoidance from damages resulted desertification is the first step. Then various methods are used to preparation of plans and maps as well as to recognize the zones. Among these, ICD method was chosen for the area. Finally the plan of the present status of desertification was provided. In this plan anthropogenic causes as well as environmental cause, the kind of process, the determining criterion and subcriterion, the class and the severity of desertification were indicated. The results show the fact that desertification phenomena with average severity took place in the area and it is extending.
