This study focuses on drought and water harvesting issues. The standardized precipitation index (SPI) was used to determine the drought characteristics of the region. To identify potential areas for water harvesting, this study employed analytical hierarchy processes (AHP) from multicriteria decision-making methods and geographic information systems. The results of the drought analysis of SPI made with the data of the Finike Meteorology Station from 1973 to 2021 showed that the dry periods for the last 3 years have been more severe than the previous ones. The study determined six criteria based on the geographical and meteorological characteristics of the area: land use, river distance, geology, slope, precipitation, and temperature. The AHP was used to determine the weights of the criteria, and the results showed that precipitation was the most important criterion, followed by slope, river distance, geology, temperature, and land use. Weighted overlay analysis was performed on the criteria, and it was found that there was a suitable area with 23% strength for water harvesting. [ABSTRACT FROM AUTHOR]
