Abstract Asian countries have among the highest numbers of people exposed to the impacts of climate-related hazards and, thus, at greatest risk of mass death. Floods, droughts, and storms have always tested civilian governments and international humanitarian aid agencies. However, climate change threatens to make the problem worse by increasing the intensity and possibly the frequency of climate-related hazards. Humanitarian emergencies potentially upend and reverse progress on development priorities, making improved spatial awareness of likely hot spots a priority for adaptation and preparedness. This article presents the findings of the effort to map sub-national “climate security vulnerability” in 11 countries in South and Southeast Asia. Climate security vulnerability is defined as areas where large numbers of people are at risk of death due to exposure to climate-related hazards and the follow-on consequences of exposure, including but not limited to conflict. The Asian Climate Security Vulnerability Model Version 1 (ACSV V1) found that Bangladesh, parts of southern and western Myanmar (the Ayeyarwady region and Rakhine state), and parts of southern and northwest Pakistan (Sindh and Khyber Pakhtunkhwa provinces) were the most vulnerable from a climate security perspective. In terms of absolute numbers, the largest numbers of people who are exposed to climate hazards are in India followed by Bangladesh. Model results are compared with a geo-referenced version of the EM-DAT Disaster Database and by creating alternative model specifications informed by a survey of 18 regional experts.

Climate change is expected to have severe consequences on the lives and livelihoods of millions of people around the world, but its effects will not be evenly distributed. Africa is thought to be especially vulnerable, given both high exposure to climate change and relatively low community resilience and governance capabilities. With climate change adaptation looming ever larger as an important policy area, understanding where climate vulnerabilities are located therefore has immense practical significance. This article details the methodological refinements made to an existing model of climate security vulnerability, the rationale for the approach, and the findings. The model introduces more fine-grained data and new methods of normalizing the data to retain more granularity, as well as other changes. The vulnerability maps show the Horn of Africa (Somalia in particular), South Sudan, the eastern coasts of Madagascar and Mozambique, northern Nigeria and southern Mali, Burundi, Sierra Leone and Guinea, as well as pockets along rivers and coasts in Egypt and Nigeria to be the most vulnerable. For validation, the model is also compared to maps of climate-related disaster counts, fatalities, and affected populations derived from the EM-DAT International Disaster database.
