The Sahel Collapse: Why a Region of 90 Million People Is Slipping Beyond Governance

How a Region Became Ungovernable

The Sahel is a strip of semi-arid land stretching from Senegal in the west to Sudan in the east, home to approximately 90 million people across five countries that share a common set of structural vulnerabilities. These vulnerabilities, including land degradation, rapid population growth, weak tax bases, and governing institutions that have never fully extended authority beyond capitals, have been present for decades. What changed in the 2020s was not the vulnerabilities themselves but the acceleration of their consequences.

The sequence of coups, beginning in Mali in 2020, extending to Guinea and Sudan in 2021, then Burkina Faso in 2022, and Niger in 2023, reflects a regional contagion of a particular political formula. Young officers, often with genuine popular support at the moment of seizure, have presented themselves as alternatives to civilian governments that were seen as corrupt, ineffective, and too closely aligned with former colonial powers. France, which had maintained military presences across the region since independence, became the primary target of popular resentment, providing the juntas with a ready-made nationalist narrative.

The Departure of Western Partners and Its Consequences

The expulsion of French forces from Mali, Burkina Faso, and Niger was not simply a diplomatic rupture. It removed the primary operational capability that had been containing insurgencies in the region since 2013, when France launched Operation Serval to prevent a jihadist advance toward Bamako.

French forces were replaced, primarily in Mali, by personnel from the Wagner Group, the Russian private contractor network that has since been reorganized under the Africa Corps brand following the death of Yevgeny Prigozhin. The evidence from Mali, where this transition is most advanced, is not encouraging. Credible reporting from the United Nations and independent monitoring organizations documents large-scale violence against civilians, destruction of villages, and no meaningful improvement in territorial control. The insurgency that Wagner was brought in to suppress has instead expanded its geographic footprint.

The United States, which maintained counterterrorism facilities in Niger and Chad, has also been compelled to withdraw. The result is a region in which the international security architecture of the previous decade has largely dissolved, with no credible replacement in place.

Climate as an Accelerant

The governance collapse in the Sahel cannot be understood without accounting for the climate dimension. The region has warmed at approximately 1.5 times the global average rate. Lake Chad, which once covered 25,000 square kilometers, has shrunk by 90 percent over the past 50 years, displacing millions and reducing the agricultural base that millions of livelihoods depend on.

The connection between climate stress and conflict is not simple or deterministic, but it operates through specific mechanisms. Competition over shrinking water and land resources intensifies intercommunal tensions that governance institutions might otherwise manage. When those institutions are weak or absent, the resulting violence creates displacement, which creates further competition over resources, which generates further violence. This feedback loop is now clearly visible across multiple Sahel countries.

Who Benefits From the Disorder

The disorder in the Sahel is not uniformly bad for all actors. Russia has extracted mining concessions in Mali and Burkina Faso in exchange for security contracts. Jihadist organizations affiliated with both al-Qaeda and the Islamic State have used the security vacuum to expand territory, recruitment, and taxation of local populations. Smuggling networks that move narcotics, arms, and people northward toward Europe have found the reduced presence of state authority to be operationally convenient.

For Europe, the consequences are already arriving. Irregular migration flows from and through the Sahel have become a recurring political issue in France, Germany, and Italy. The complete breakdown of governance in West Africa would substantially increase these flows, creating domestic political pressures that are already significant.

The Case for Re-engagement and Its Obstacles

The argument for renewed international engagement in the Sahel is compelling on humanitarian and strategic grounds. The argument faces three obstacles.

First, the junta governments have demonstrated through their expulsion of Western partners that they do not want the form of engagement that Western countries are prepared to offer, which involves governance conditionality and human rights standards that are politically inconvenient for unelected governments. Second, the populations of these countries, while suffering greatly from the consequences of poor governance, have in many cases expressed genuine support for the nationalist narratives that brought the juntas to power. Third, there is no current consensus among Western governments on what an alternative engagement strategy would look like or who would lead it.

The most realistic near-term scenario is continued deterioration, punctuated by humanitarian emergencies that attract temporary international attention without producing durable policy responses. The generation now growing up in the Sahel, surrounded by violence, displacement, and failed institutions, represents a long-term governance and stability challenge that will shape the region for decades regardless of what external actors choose to do in the near term.
