Abstract

One of the natural disasters that is increasing in frequency due to the phenomenon of climate change and very detrimental to agriculture is drought. Future drought events need to be known so that adaptation and mitigation can be carried to avoid large losses. The purpose of this study is to determine the amount of future precipitation in the next 25 years (2025–2049) and to determine the drought category of the SPI based on climate change scenarios RCP2.6, RCP4.5, and RCP 8.5. The initial stage of the study was carried out by calculating future precipitation with a 5-year period during 2024–2049 based on the RCP2.6, RCP4.5, and RCP 8.5 scenarios. This calculation is done using SDSM software version 4.2. The next step is to calculate the 3-month SPI from future precipitation data for each scenario. The results show that the worst 3-month SPI drought index shows extreme dry conditions in the RCP2.6 scenario during the 2040–2044 period, in the RCP4.5 scenario during the 2035–2039, and in the RCP8.5 scenario during the 2030–2034 period.
