Current vulnerabilities and climate change impacts vary across diff erent parts of the country. These highly localised aspects of climate change require actions that are tailored to local needs and circumstances, with meaningful participation of local people. As Cambodia goes through a critical period in implementation of public administration reforms and expansion of the process of decentralization and deconcentration in accordance with the Organic Law (2008), there exists a great opportunity to think through what it would mean to address climate change at sub-national level.
