Nature-Based Solutions for Flood Risk Management: Revitalizing Philippine Rivers to Boost Climate Resilience and Enhance Environmental Stability

The Philippines is preparing for more severe and frequent flooding as climate change ramps up extreme weather events. This brief shares insights from pilot projects developing integrated flood risk management in major Philippine river basins. It distills lessons on harnessing the functions of natural river systems to boost climate resilience at relatively low cost. Nature-based solutions include restoring wetlands, developing water retention areas, removing obstacles, and reviving old channels. They can complement conventional infrastructure to improve flood protection and create additional environmental and social benefits.
