This research represents an initial step towards understanding the major problems identified by communities as priorities to be addressed in order to become less vulnerable to climate related risks as well as other kinds of event. The research has two goals: to research and document the priorities expressed by the communities and identify better ways to support grassroots civil society building and networking. It also provides an introductory review of climate change in Cambodia, which is considered highly vulnerable to climate change, and a review of the vulnerability analyses that constitute the ground for adaptive policies. The primary data of the study were collected through qualitative methods based on group discussions with communities in five Cambodian provinces: Prey Veng, Battambang, Kampong Speu, Kampot and Mondulkiri. In all the communities villagers have observed important changes in climate and weather patterns.
