Abstract

The aim of this study was to apply COPRAS and Grey COPRAS multi-criteria decision making methods to selection of the best agricultural sector water supply alternative for adaptation to the effects of climate change in Gharranghu basin in East Azerbaijan province. According to the existing hydroclimate conditions, adaptation scenarios in agricultural sectors were selected and based on the results of water resources evaluation and planning model (WEAP), Risk Indexes in each scenario were calculated based on mathematical equations. In order to prioritize and select the best alternative, adaptation scenarios were considered as alternatives, and Risk Indexes are regarded as criteria in COPRAS and COPRAS-G multi-criteria decision making methods. Results showed Risk Indexes will be improved by implementing adaptation policies, so that drought risk index would decrease through reduction of water consumption from 5% to 25%. Also, the best alternative for adapting the impacts of climate change phenomenon by using COPRAS Method was the fifth alternative, namely 25% reduction in water demand in agricultural sector, while COPRAS-G method introduced second alternative namely 10% reduction in water demand as preferred alternative. It should always be assumed that any prediction of results for the coming years is associated with uncertainty due to complex climatic conditions and its resulting effects.
