摘要

This study analyzes groundwater drought in the Konya Closed Basin over the period 1967–2019, with an emphasis on the anthropogenic pressures in affecting hydrological drought conditions. Standardized Groundwater Level Index method was employed for examining drought conditions for short-term datasets covering seasonal, 6, and 9-month periods, alongside long-term datasets spanning 12, 24, and 36-month periods. Our findings highlight the severity of drought occurrences during winter, spring, and across the 12, 24, and 36-month periods. Sub-basins such as Beyşehir, Altınekin, and Çumra stand out for experiencing the highest rates of severe and extreme drought. The Konya Closed Basin, characterized by limited surface water and excessive groundwater utilization, has witnessed a rapid proliferation of wells since the 1990s. The average decrease in water levels from 1954 to 2018 stands at 15.9 m, with an annual reduction rate of 56.8 cm. If the impacts of hydrological drought resulting from unplanned and improper irrigation practices in the Konya Closed Basin are not mitigated, the ensuing consequences could result in serious threats to food and water security, as well as desertification.
