Addressing desertification, due to its multi-criteria nature, increasing development, extensive and long-term impacts on natural resources and human populations, is necessary to achieve sustainable development. Therefore, for optimal utilization of facilities and limited funds allocated to this issue, evaluation of current strategies, based on different criteria is essential to avoid wasting national funds, while achieving better results. The current study used Decision Making Trial and Evaluation Laboratory (DEMATEL) to rank desertification strategies in the context of Multi-Attribute Decision-Making (MADM) models. First, important and high-priority criteria and strategies were identified within the framework of MADM, using the Delphi method. Then, the final priority of strategies was determined using the DEMATEL method. Based on the obtained results, vegetation cover development and reclamation (A23), change of irrigation patterns and implementation of low water demand methods (A33), and livestock grazing control (A20) were recognized as the most important combating desertification strategies in the region. Therefore, it is suggested to consider the obtained results and ranking in control plans to reduce the effects of desertification and reclamation of destructed lands.

In this research, a web-based decision support system was designed and developed to improve water quantity and quality status in the Bonekooh watershed, Hable-rud River Basin, through introducing the characteristics of the watershed in a systemic manner and introducing possible solutions and choosing the best management practices. In this research, MySQL environment was used to manage the data and generate the data base. Generating model base and multi criteria decision making analysis were done using PHP programing language and SAW and TOPSIS methods were used to prioritize the management options. In addition, HTML programing language was used to develop the graphical user interface. The developed system provides a brief introduction of the watershed characteristics in the form of the DPSIR systemic approach and then presents the problems structure and shows the cause and effect relations between the variables of the system in the form of a conceptual model. Then, a set of vegetation-based solutions and their spatial distribution are provided to the users. In the process of modeling the possible impacts of the proposed solutions and their different impacts are predicted and presented separately considering all evaluation indices proportion. Finally, following assigning different weights to the evaluation indices by the users, results of prioritizing the management options are presented to the users using multi-criteria decision-making methods. This decision support system is useful to all potential users including expert and general stakeholders and hence it improves and facilitates the decision-making process.
