Abstract

Select appropriate Alternatives considering all effective desertification measures can have effective aid in controlling, Reclamation and rehabilitation of degraded areas and prevent the destruction of endangered areas. Therefore, this study was performed to provide a systematic and optimal Alternative in a group decision-making model. To this end, first in the framework of Multiple Attribute Decision-making (MADM) the preference indices were obtained using Delphi model, and then priority Alternatives were evaluated using Linear Assignment method (LA). Based on the results, to prevention of unsuitable land use changes (A18), the vegetation cover development and reclamation (A23) and modification of ground water harvesting (A31), were identified as the main combat desertification Alternatives in the area, respectively. Therefore, it was suggested that the results and ranking obtained should be considered in controlling and reducing the effects of desertification and rehabilitating degraded lands plans.
