While synergies among climate change adaptation and mitigation (CCA&M) policies clearly exist, little common understanding has been established on how to introduce CCA&M policies in an integrated manner. A holistic approach to land-use planning and management at the local level can help meet this challenge. To test this idea, with support from the Ministry of the Environment, Japan, the Institute for Global Environmental Strategies and the University of the Philippines at Los Baños launched a pilot project with local governments in the Philippines in 2014. This project aims to examine the necessary conditions for integrating climate change measures – adaptation and mitigation – by improving land-use planning at the river basin level. The project spans several cities in one watershed in the Philippines and engages municipalities and government agencies.
