This paper looks at effects of climate change on vulnerable countries in Africa. The authors note that countries such as the Democratic Republic of the Congo (DRC), Guinea, Sierra Leone, Somalia, and South Sudan are particularly vulnerable to climate change because they are less resilient and have weak governance systems. It also underscores how climate change is increasingly becoming a security threat to most countries, which often prompts deployment of militaries to provide humanitarian assistance. The authors recommend that governments should mobilise and allocate resources to combat climate change, just as they would for internal and external security threats to their countries.
