Flooding in Tempe Lake, Indonesia, poses ongoing socioeconomic challenges, mainly affecting food security, agricultural output, and household livelihoods. The recurrent and unpredictable floods disrupt planting and harvesting periods, resulting in significant food production deficits and posing complex adaptive challenges for residents. This study examines the socioeconomic adaptation strategies employed by rice farmer households to mitigate the adverse effects of flooding. The study analyzed a random sample of 160 people, utilized descriptive–analytical methodologies, and displayed the findings through graphs and matrix tables. Research reveals that fishing and rice farming serve as the primary revenue sources for households in the region. Despite financial challenges, households maintain security due to dependable food sources and proximity to the lake. The study emphasises the importance of efficient rice cultivation management owing to its short growth cycles and vulnerability to flooding. Moreover, freshwater aquaculture presents a sustainable strategy for mitigating flood risks in climate change, mainly when supported by microcredit, training, and improved market access. The findings highlight the necessity of social and structural adjustments in reducing vulnerability and enhancing community resilience, offering substantial recommendations for improving long-term resilience and food security in flood-prone regions.
