Eromoko is a drought-prone district in Wonogiri Regency, Central Java, thanks to the karst landform and steep topography that dominate almost half of district’s area. Drought usually hits the district during the dry season and harms many sectors, especially agriculture, household, and health. However, the level of drought risk is different in each part of the district. It depends on the hazard, vulnerability, and adaptive capacity aspects of each region. This research aims to generate drought risk map based on those aspects then identify the high-risk zone where resources urgently need to be managed towards resilient development. All information analyzed in this research were obtained from secondary data. Combination between qualitative and quantitative analyses, as well as rank method were then applied to it. Drought hazard map was generated from geological, soil, and elevation data. Social vulnerability map was generated from population density, disability ratio, and sex ratio data. Economic vulnerability map generated from paddy field ratio and dry field ratio data. Adaptive capacity map was generated from educated people ratio. Social vulnerability, economic vulnerability, and adaptive capacity maps were then overlayed and resulting a drought vulnerability map. Drought risk map was obtained by integrating hazard and vulnerability maps using rank method. Suitable resource management for high-risk area was then analyzed by considering the entire risk factors. The drought risk assessment result successfully identified Basuhan, Pucung, Ngandong, Tempur Harjo, Panekan, and the southwest part of Pasekan as the high-drought risk zones. The risk in Basuhan and Pucung is mainly controlled by geological, soil, and topographical conditions; low educational level; as well as the high dependency on agricultural sector. Topographical conditions and high dependency on agricultural sector are the main risk factors in Ngandong and Tempur Harjo Villages. Risk level in Panekan is mainly controlled by high dependency on agricultural sector, as well as high ratio of disability and sex ratio. As for the case of Pasekan, geological and soil conditions are the main factors. Finally, different resource management based on critical risk factors in each area is recommended by this reasearch in order to achieve resilient development in Eromoko District.
