The 'Vulnerability Assessment and Adaptation Programme for Climate Change within the Coastal Zone of Cambodia Considering Livelihood Improvement and Ecosystems' aims to increase the resilience of natural ecosystems, such as mangrove forests, along the coast (as well as their functioning as buffer systems) and reduce the vulnerability of coastal communities to climate change impacts and risks. The present document is intended as a reference for training-of-trainers and training of professional practitioners. It builds comprehensively on recent studies and documentation prepared by Ministry of Environment in connection with the PPCR (Phase 1) and the CARP. A related manual, addressing training and awareness-building at the commune level, is in preparation under the CARP. The document is divided into 2 parts, intended for related but distinct applications: A: Climate Change and Adaptation Planning (with a glossary) B: Vulnerability Assessment and Reporting
