Flood Risk Perception and Adaptation in Martapura River

Indonesian river basin towns face flood disasters that damage lives, infrastructure, and socioeconomic stability. Recent flood frequency and intensity have increased in the Martapura River settlements in Banjar Regency, South Kalimantan. This study examines flood risk perception and adaptation measures. The study analyzes flood risk perception, adaption strategies, and factors affecting them among residents. The 2023 mixed-method study combined quantitative surveys (n=358) and qualitative interviews (n=25) in five sub-districts over six months. The study found that previous flood experience was the best predictor of high-risk perception and adaptation strategies across geographic and socioeconomic boundaries. The adaption options ranged from structural changes to community-based efforts. Local government announcements and social media were primary sources, but environmental knowledge was low. Cultural linkages to the river and economic limits shaped adaptation. These findings highlight the necessity for personalized risk communication, improved early warning systems, and local expertise in modern flood control. The work adds to the knowledge on community resilience in flood-prone developing nations and informs policymakers and disaster managers. Future research should focus on long-term climate change adaptation techniques and novel ways to overcome economic barriers to individual and community flood resilience.
