Four of the 10 countries most affected by climate change in the past 20 years are in Southeast Asia. As such, climate change poses a profound threat to populations across the region, spanning traditional security dimensions as well as non-traditional aspects such as food, water and health security. In particular, marginalised groups such as women, the disabled, rural populations and refugees are disproportionately affected by climate-induced security threats and yet have limited capacities to adapt to these changes.
