The Climate Change–Terrorism Nexus: A Critical Literature Review

A growing number of policymakers around the world have recognized climate change as an escalating security threat and increasingly point to the climate change—terrorism nexus in particular. This critical literature review provides an analysis of the current state of research on the causal and correlative links between climate change, intermediary factors—such as resource scarcity, loss of economic opportunities, and instability—and terrorism in sub-Saharan Africa. Moving beyond a review of substantive themes within the existing body of scholarly research examining this topic, this article critically evaluates the theories, assumptions, and methods behind the literature. In doing so, the review identifies noteworthy trends, as well as gaps and shortcomings in the current research. Our review finds that the majority of the literature has observed a positive correlation between climate change and terrorism. More precisely, the current body of research overwhelmingly assesses that climate change indirectly leads to terrorism via its impact on conditions often considered to be drivers of terrorism in sub-Saharan Africa. Still, gaps remain in empirically backing up these assertions and examining the relationship between climate change, intermediary factors, and terrorism in more depth. We use our critical review and analysis to guide recommendations for further research into this emerging and timely field of study.
