Sahel insecurity is the product of vulnerabilities inherent to the geography of the region, while other security challenges arise from political and demographic factors. Militant Islamist groups have increasingly exploited these vulnerabilities, necessitating joint regional cooperation from regional powers if they hope to effectively combat the militant threat.
The Sahel region, a geographic belt separating desert from savannah, stretching from the west coast of Africa to the east coast, faces numerous security and stability threats. Non-state actor groups consisting of militants, rebels and terrorists are a particular source of instability and violence. These groups include: al-Qaeda in the Islamic Maghreb (AQIM) and its various affiliates and offshoots who are concentrated in north-western Africa; Boko Haram in north-eastern Nigeria and the Lake Chad area; and al-Shabaab in Somalia and Kenya. To a limited but increasing extent, groups or factions within pre-existing militant movements, aligned with the Islamic State (ISIS), are also making their presence felt across the region.
