It is undoubtedly a challenge for climate policy actors to identify reliable evidence to support sound decision-making processes for tackling climate issues effectively. Still, differentiating between fact and fiction, well-designed and invalid science, evidence- or interest-based arguments is precisely what determines the quality of climate policies.

This policy brief considers the interlinkages between climate change, migration and security. It argues that despite the lack of scientific consensus the potential consequences are too large to ignore and no-regret policy options should be adopted.

This report combines the conclusions of several scientific studies and the opinions of numerous researchers and specialized organizations that have focused these past few years on the link between climate and security. It highlights the essential contributions of a collective group of experts in order to concentrate on this issue and encourage institutions such as foreign and defense ministries to adopt new approaches.

In this report, various challenges faced by Asia-Pacific's most vulnerable areas to disasters attributed to climate change are specified, and a qualitative analysis is made on the instability of public security, politics and social climate observed in the region. The purpose of these two exercises is to gain insight into the situation through the overlapping of natural science and social science perspectives.
