The Philippines is one of the most vulnerable countries to climate risks both current and future. Annually, the country experiences the havoc caused by tropical cyclones. Every few years, the ENSO phenomenon adds another layer of confusion to the weather patterns. As a result, small farmers in the country have developed ways of adapting to such seemingly capricious climate. This book arose out of pioneering research in one of the most important watersheds in the country. When it started in 2002, there was hardly any information on the impacts of climate change on Philippine watersheds and their natural and social systems. This book examines how climate change could affect our forests, water resources and local communities.
