Climate change is a global phenomenon that is being experienced by all levels of society, regardless of race and species, and in all types of ecosystems, regardless of geographic location. It will have diverse effects on biodiversity which will directly impact on food security, water supply, and livelihood among others, especially for the poor and more vulnerable sectors of human society. More importantly, all forms of life including human society are trying their best to adapt and survive. This book explores the two-way link between climate change and the state of biodiversity in Southeast Asia. By drawing on the experiences and lessons shared by representatives from research and development agencies, academic institutions, donors, and other organizations; and the crosscutting issues contributed by experts, this book aims to provide insights, lessons, and perspectives on how Southeast Asia is dealing with these twin concerns. This book is invaluable to all who are interested in assessing research gaps, identifying future research areas, drafting effective policy agenda, and implementing critical activities at the community, national, and international levels.
