The Sahel, the semi-arid African region stretching from the Atlantic Ocean in the west to the Red Sea in the east, has become the epicentre of global terrorism, given the high number of attacks by armed groups and the resulting fatalities, including those suffered by civilians. This development is rooted in a complex interplay of factors. They include state fragility, illicit economies, limited presence of government in rural areas, and conflicts driven by resource scarcity due to climate shocks.
I am a political scientist with regional expertise in conflict, security and development in west Africa. In a recent policy brief for a research programme, I set out how climate change mitigation efforts in Sahelian communities have intensified pre-existing tensions.
The research involved extensive fieldwork and interviews in July and August 2025 with community members in Burkina Faso, Mali, Niger and Nigeria. The aim was to understand the interaction between various pressure points and crises playing out in their lives.
