Evaluation of de-desertification alternatives in Ardakan-khezr abad plain by using shannon entropy method and oreste model

Abstract Nowadays, Desertification is one of the greatest environmental challenges. It is a global issue and its serious consequences affect on biodiversity, environmental safety, poverty eradication, economic and social stability and sustainable development around the world. Despite the serious environmental, social and economic impact of desertification phenomenon, few studies have been done in providing optimal alternatives. This paper tries to provide systematic and optimal alternatives in a group decision-making model. At the first in the framework of Multiple Attribute Decision-making (MADM), indices preference was determined using shannon entropy, then alternatives priority was evaluated by ORESTE model. The results showed that alternative of vegetation cover development and reclamation (A23) with general rating of = 46.5 is the most important alternative in de-desertification prosess in the study area, and alternatives of prevention of unsuitable land use changes (A18) and Livestock grazing Control (A20) were in the next priority with general rating of 53.5 and 69, respectively. Therefore, it is suggested that the obtained results and ranking should be considered in projects of controlling and reducing the effects of desertification and rehabilitatyion of degraded lands plans.
