Summary:Bangkok is a key city in the framework of the "Belt and Road" initiative in Southeast Asia. However, the economy, agriculture, and ecological environment of Bangkok is now facing significant risks due to frequent drought disasters in recent years, resulting in substantial economic losses. This study is based on the theory of natural disaster risk assessment and evaluates the risk of drought disasters by analyzing the factors causing disasters and the vulnerability of affected areas. We examine the spatial distribution of drought hazard risk, vulnerability, and overall risk in the Bangkok node area from 2000 to 2020, employing univariate linear regression analysis and the Mann-Kendall test to assess changing trends and spatial distribution characteristics. The results showed 41.64% of the land in the study area had a moderate or higher risk of drought disasters, with the highest risk areas located in the northwest of Nakhon Pathom and the central part of Pathum Thani. The risk levels in the region are determin
