Abstract

A primary component of nature is wetlands, which are of special ecological and environmental importance and are valuable for people in different aspects. On the other hand, environmental risk assessment is an important instrument to identify and manage the environment and alleviate environmental damage in order to reduce the adverse results for achieving sustainable development. The present research aimed to evaluate and rank the environmental risks of the International Hamoun Wetland in the Sistan region using fuzzy simple additive weighting (fuzzy SAW) and grey relational analysis (GRA). The research was conducted by the survey method using a questionnaire in which 50 experts of the Regional Agriculture and Natural Resources Organization were interviewed. Based on ranking by the fuzzy SAW method, the economic factor gained the highest score of 4.91 followed by the cultural, biological, and social factors. The GRA results also ranked the economic factor at the top with a final weight of 0.62 followed by the cultural, biological, and social factors in the next ranks. The local communities and the Department of Environment are recommended to cooperate for the protection and revival of the Hamoun wetland in order to bring a balance to this wetland using the Comprehensive Hamoun Management Program.
