It is imperative to develop and assess approaches to adapt to climate change in order to manage its impacts. The objective of the present study was to explore the impact of the changes in climatic parameters on water resources management and to assess the efficiency of changing water uses as a strategy to mitigate the impacts of water shortage in Southeastern Iran. To assess the variations of temperature and precipitation parameters an ensemble of fifteen GCM models was used, and the emission scenarios A1 and B1 with emphasis on uncertainty and water resources management were simulated by the Water Evaluation And Planning System (WEAP) model using data derived from climate change and local station data. The calibration was done by the WEAP model algorithm. Climate change results showed a increase in temperature and precipitation. Due to the increase in temperature relative to precipitation, the region's water demand will increase. The slight increase in rainfall does not mean supplying the region's water demand, especially the agricultural demand. Therefore, the impact of climate change is having a greater impact on farmers because their livelihoods depend on water. These conditions will lead to further problems, including migration. These conditions require effective solutions. One of the best solutions is to gradually eliminate agriculture and replace it with industry. The results showed that with this scenario, the water demand of different sectors will be met, the local environment will not be destroyed, and low-income, non-permanent, and illicit jobs like fuel smuggling will be eliminated.
