Unveiling transboundary challenges in river flood risk management: learning from the Ciliwung river basin

This study presents the issues and challenges emerging from transboundary river flood risk management in the Jakarta metropolitan area of Indonesia, posed by the massive urban development and dramatic increases in annual flooding,

Previous studies have addressed the challenges of flood risk, but they have tended to overlook transboundary issues and power sharing. To tackle future flood events, this paper aims to unveil transboundary challenges and power sharing in flood management, learning from Ciliwung River. As the longest river basin crossing cities and regencies of Greater Jakarta, the complexity of Ciliwung flood risk management was driven by flood variables triggered not only by natural, physical, and socioeconomic factors, but also by transboundary challenges and power sharing. This study contributes to the literature on governance of flood risk management by emphasizing the need for a coordinated and integrated approach to mitigate flood risks that extend beyond administrative boundaries, enhancing overall resilience and sustainability.
