Drought risk assessment is usually performed qualitatively and quantitatively depending on the definition a drought. Themeteorological drought indices have a limit of not being able to consider the hydrological components such as evapotranspiration,soil moisture and runoff, because it does not consider the water demand in paddies and water supply in reservoirs. Agriculturaldrought was defined as the reservoir storage shortage state that cannot satisfy water requirement from the paddy fields. The objectivesof this study were to suggest improved agricultural drought risk assessment in order to evaluate of regional drought vulnerability andseverity studied by using Reservoir Drought Index (RDI). The RDI is designed to simulate daily water balance between availablewater from agricultural reservoir and water requirement in paddies and is calculated with a frequency analysis of monthly waterdeficit based on water demand and water supply condition. The results indicated that RDI can be used to assess regional drought riskin agricultural perspective by comparing with the historical records of drought in 2012. It can be concluded that the RDI obtainedgood performance to reflect the historical drought events for both spatially and temporally. In addition, RDI is expected to contributeto determine the exact situation on the current drought condition for evaluating regional drought risk and to assist the effectivedrought-related decision making.
