Abstract

Agricultural droughts have been increasing in both frequency and severity in South Korea, necessitating a comprehensive assessment of regional drought response capabilities. This study aims to evaluate agricultural drought response capacity by estimating paddy field areas using spatial analysis techniques. Unlike previous studies that relied on si, gun, and gu-level data, this research utilizes detailed farm map data to improve the accuracy of paddy field area estimation. South Korea was divided into six major river basins—Han, Geum, Nakdong, Yeongsan, Seomjin, and Jeju—for the analysis of paddy field distribution and drought vulnerability. The results show that the Geum Basin has the largest total paddy field area at 286,917 ha, followed by Nakdong (200,108 ha) and Han (158,689 ha), with Jeju having the smallest area at 15 ha. The study classified 1,995 administrative units into four categories based on drought response capacity: high (25%), moderate (35%), low (25%), and very low (15%). The most vulnerable areas were concentrated in the Nakdong (15.2%) and Geum (18.9%) basins, where frequent drought events and limited water resources increase risk. In contrast, the Yeongsan (35.8%) and Seomjin (39.4%) basins demonstrated stronger drought resilience due to well-developed irrigation infrastructure. This research provides a quantitative framework for evaluating agricultural drought vulnerability at a fine spatial scale, offering valuable insights for targeted water resource management and policy development.
