This study assessed the reliability of the agricultural water supply based on future climate change scenarios, and suggested plans to improve thereliability in order to promote the adaptability of irrigation water in agricultural reservoirs to climate change. The assessment of agricultural watersupply reliability was performed on reservoirs which had a lower water quantity than their design basis and which had recently been subject todrought. In other words, from the irrigation districts of main intake works among the reservoirs managed by the Korea Rural Community Corporation,1∼2 districts in each province–that is, a total of 13 districts -that were recently designated as a district for securing agricultural water (droughtprevention district) were selected. Climate change scenarios were applied to the selected districts to analyze their future water supply reliabilitycompared to the current level. All districts selected showed a drought frequency of 4 years or shorter, which demonstrated the need to establishclimate change response plans. As plans for responding to climate change, a plan that utilizes supplemental intake works to reduce the area of theirrigation districts of main intake works, and another one that increases the capacity of main intake works were adopted to reanalyze their water supplyreliability. When the area of the irrigation districts of main intake works was reduced by about 30∼40%, the drought frequency dropped to morethan 10 years, securing the reliability of water supply. To secure the reliability by increasing the capacity of main intake works, it was calculatedthat about 19,000∼2,400,000 tons need to be added to each reservoir. In addition, climate change response plans were suggested to improve thereliability of the water supply in each district based on the results of economic analysis.
