The Sahel is in freefall. On Tuesday, a coordinated terror attack on an airport near Niamey, Niger, left 35 people dead and dozens wounded, marking one of the deadliest assaults in the region’s recent history. The attackers, linked to Islamic State in the Greater Sahara, targeted a military transport plane and civilian terminal, highlighting the failure of decades of counter-insurgency efforts.
This is not an isolated incident. The Sahel has become a graveyard for state authority. Since 2012, militant groups have metastasised from Mali into Niger, Burkina Faso, and beyond. The region now accounts for nearly half of global terrorism deaths, according to the Global Terrorism Index. The attack on Niamey airport, 10 kilometres from the capital, demonstrates that no location is safe. Not the capital. Not an airport. Not a military base.
The physics of collapse are clear: as state control erodes, feedback loops accelerate. Weak governance allows militants to operate. Militants undermine governance. Civilian casualties rise. Trust in government plummets. Recruitment for extremist groups swells. It is a thermodynamic cycle of destruction, one that has driven over 2.5 million people from their homes across the Sahel.
Niger’s government, already fragile after a coup in July 2023, has struggled to respond. The junta has expelled French troops and turned to Russian mercenaries from the Wagner Group. But Wagner has failed to deliver security elsewhere in Africa. In Mali, their presence has coincided with increased civilian massacres. The airport attack in Niamey suggests that trading one colonial power for another yields no strategic advantage.
Climate change compounds the crisis. The Sahel is warming 1.5 times faster than the global average. Rainfall patterns have become erratic, devastating subsistence farming. Lake Chad has shrunk by 90 per cent in 50 years. This environmental stress drives competition for resources, fuels local conflicts, and creates fertile ground for terrorist recruitment. It is not coincidence that the regions with the highest levels of terrorism are also those experiencing the most acute climate impacts.
The international response has been inadequate. The UN peacekeeping mission in Mali, MINUSMA, withdrew in 2023. The G5 Sahel joint force, designed to coordinate regional security, has been paralysed by political infighting. Meanwhile, European countries focus on border controls to prevent migration rather than addressing root causes.
What would a meaningful response look like? First, a massive investment in renewable energy for the Sahel. Solar power could provide clean electricity to off-grid communities, reducing dependence on charcoal and firewood that contribute to deforestation. Second, support for climate-resilient agriculture: drought-tolerant crops, improved irrigation, and restoration of degraded land. Third, a diplomatic push for inclusive governance that addresses grievances of marginalised groups, particularly pastoralists and youth.
These are long-term solutions. In the short term, the attack on Niamey airport will likely trigger another round of military strikes and curfews. But the cycle will continue until we recognise that the Sahel is not just a security problem. It is a system in collapse. The graphs of rising temperatures and increasing terrorist attacks are not correlation. They are causation. We are running out of time to intervene before the collapse becomes irreversible.
