This study was conducted in the Antalya Basin to investigate the effects of climate change on drought. According to researches, the Antalya Basin is located in the Mediterranean Basin, which is one of the region expected to be most affected by climate change. It is estimated that the losses of drought events rely on climate change will increase depending on the drought characteristics. To keep drought's adverse effects and economic dimensions under control and reduce them the minimum levels, it is essential to calculate drought frequency, severity, duration, and affected area as priority tasks and conduct temporal and spatial analyses of drought characteristics. This study used the Standardized Precipitation Index (SPI) to identify and characterize drought events in the Antalya Basin. Meteorological stations with precipitation records from 1969 to 2022 (54 years) were used for drought analysis in the Antalya Basin. The effects of global climate change on drought indices and characteristics in the last years have been investigated using the Mann-Kendall (MK) and Innovative Trend Analysis (ITA) methods. The analyses revealed that climate change has caused significant increases in drought events' duration, severity, and frequency. It is emphasized that the Mediterranean Basin will be one of the most sensitive regions in the future due to climate change. As a result of this study, changes in drought characteristics due to climate change also reveal similar sensitivity for the Antalya Basin. Increasing temperature and decreasing precipitation in the basin, which is highly sensitive to drought, will further reduce the use of limited water resources. These research results of the Antalya Basin obtained that drought and climate change should be taken into consideration more than ever in the future when planning and managing of water resources.
