| Abstract | The Kok River Basin in Northern Thailand, is a critical watershed that supports agriculture and local ecosystems. This study aims to analyze the impact of drought on the Kok River Basin from 2014 to 2017, utilizing the Standardized Precipitation Index (SPI) to assess drought conditions across different periods. The research is based on 31 years of rainfall data (1987-2017) from 15 rainfall stations within the basin. The SPI3 and SPI6 indices were calculated to determine drought severity during the early rainy season (May-July) and throughout the entire rainy season (May-October), respectively. A comparison between SPI data and El Niño events was also conducted to understand the influence of global climatic phenomena. Results show that in 2015, SPI3 reached a value of -2.38, and SPI6 recorded -2.83, indicating severe drought conditions. The hardest-hit regions included Wiang Pa Pao, Mae Suai, Mae Lao, and Mueang Chiang Rai districts, where drought conditions were closely associated with a strong El Niño event. These findings highlight the necessity of adopting effective drought management strategies, particularly the 2P2R framework (Prevention, Preparedness, Response, and Recovery), to enhance adaptive capacity and mitigate future drought impacts. Policymakers and stakeholders are encouraged to integrate sustainable water management practices and climate data into both local and regional planning to build resilience against climatic extremes. |
