Abstract

Flood risk management in a floodplain area with high population density has complex challenges. Almost all communities in that area are unwilling to move even though they are aware of the potential for flooding. This study aims to: 1) develop knowledge and understanding of community-based flood risk management in Malang City, Indonesia; 2) assess the cost effectiveness of the flood risk management; 3) develop a framework for building community-based flood risk management. This study used a mixed method combining quantitative and qualitative approaches. The results show that the understanding of the flood risk and the potency of flood emergency response of the local government significantly influence building community-based flood risk management system. This system can reduce the flood risk up to 30% compared to before the implementation of that system, and provides direct financial benefits. The total benefit can be cost effectiveness of up to 49.2% in a year.
