Analysis of Rainfall Variability in 2008-2024 and Its Impact on Rice Productivity in Sidenreng Rappang Regency

Rainfall variability is a critical factor that affects agricultural productivity, especially rice. This study analyzes the variability of annual rainfall in Sidenreng Rappang Regency, South Sulawesi, during the period 2008–2024, as well as its impact on rice productivity. The method used was a literature review with a quantitative approach to secondary data on annual and monthly rainfall and rice productivity from BPS and NASA POWER. The results show that annual rainfall fluctuates, with a low value of 97.82 mm in 2023 and a high of 295.02 mm in 2009, influenced by phenomena such as ENSO and Dipole Mode. Rice productivity is also fluctuating, with a downward trend of about 0.0039 tons/ha for every 1 mm increase in annual rainfall based on linear regression analysis, although there is a moderate positive correlation in some periods. This variability leads to the risk of drought and flooding, which has an impact on decreased production. Climate adaptation strategies, such as irrigation management and the use of climate-resistant varieties, are needed to maintain food security in the region.
