This book highlights the current issues, challenges, and priorities for climate change adaptation in the ten member states of the Association of Southeast Asian Nations (ASEAN). The status of each country was prepared by a consortium of researchers in consultation with National Focal Points of the ASEAN Working Group on Climate Change (AWGCC). National documents on adaptation actions, including local scenario and priorities, were reviewed where available and supplemented with an assessment of scientific publications to identify vulnerable ecosystems and regions. Adaptation needs and priorities were determined through stakeholder consultation in the respective countries. This allows for local-level perspectives to be captured and brought to the attention of policy and decision-makers at the national and regional levels. An important lesson from this exercise is that universities and research institutions at the national level have a critical role to play in bridging the gap between science and policy in climate change adaptation. These institutions also have the capacity to continuously facilitate transfer of the best available science for advancing climate change adaptation at the local level.
