Rainwater harvesting as a solution for mitigation and adaptation to flood disasters (study case: Cisurupan)

Abstract

To strengthen the protected area function of the Cisurupan urban village, which is upstream of the Cinambo river, and reduce the flood risk surrounding Gedebage its downstream, Bandung City Public Works Department has attempted four green open spaces in Cisurupan since 2018 that also involve cross-actor. However, there are no studies on the positive impact of green open spaces in mitigating and adapting to flooding. This study aims to provide innovation and collaboration regarding flooding mitigation and adaptation in Cisurupan. This study uses a quantitative, qualitative approach or mixed method, while the analysis is spatial analysis for quantitative and descriptive analysis for qualitative, while the data collection method uses semi-structured interviews and participatory observation from February to May 2022. The result shows four green spaces as the mitigation and adaptation are innovative efforts to collaborate with communities, government, civic society organizations, and academics. However, there is still a lack of existing mitigation and adaptation forms, which rely only on pore drums, retention ponds, and growing media. It is possible to urge rainwater harvesting programs not only for flood risk reduction in the rainy season and clean water crisis in the dry season but also as a long-term disaster risk reduction and water resource independence.
