Seeking to better facilitate climate change adaptation knowledge at local and national levels in Cambodia, the Regional Climate Change Adaptation Knowledge Platform, through the support of the Swedish International Development Cooperation Agency, has commissioned this scoping study on climate change adaptation in Cambodia. As Cambodia moves through short term responses to climate change, it will also have to focus on knowledge needs for planned adaptation as a long term response. The building blocks to address climate change are present in Cambodia, but they need further structure and capacity development. Currently activities are planned on the bases of mandates associated with two development frameworks; food security and livelihood. Hence, adaptation to changing climate conditions is not proactive but rather reactive to past events. Needed is a fundamental change in approach to climate change adaptation –beyond addressing immediate needs… and towards innovation to meet future climate scenarios.
