This case study brief shares insights from pilot projects in the Philippines on how nature-based solutions can strengthen flood risk management in cost-effective ways.

The Philippines ranked fourth among countries to be the most vulnerable to extreme weather events such as tropical cyclones and flash floods, according to the Global Climate Risk Index 2021.

Rapid population growth and urbanization of low-lying areas further increase flood risk and endanger unprotected communities. 

This case study brief shares insights from pilot projects in the Philippines on how nature-based solutions can strengthen flood risk management in cost-effective ways.

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.
