The Sahel in 2026: How Military Juntas, Jihadists, and Climate Stress Are Reshaping West Africa
Mali, Niger, and Burkina Faso have expelled Western forces, deepened ties with Russia, and face escalating jihadist violence. A region-wide humanitarian emergency is unfolding with limited international attention.
Key takeaways
- The Alliance of Sahel States (AES) — Mali, Niger, and Burkina Faso — has formally left ECOWAS and operates as a unified military bloc aligned with Russia.
- Jihadist groups affiliated with al-Qaeda (JNIM) and Islamic State (ISGS) control more territory in 2026 than at any point since 2020.
- Over 4 million people are displaced across the three countries, and humanitarian access has deteriorated sharply since the expulsion of French and UN forces.
- Russia's Africa Corps (successor to Wagner) provides regime security but has shown limited effectiveness against insurgents in rural areas.
The junta alliance and the break with the West
Since 2020, military coups in Mali (2020, 2021), Burkina Faso (2022), and Niger (2023) have fundamentally redrawn the Sahel's political map. All three juntas expelled French military forces, ended cooperation with MINUSMA and other UN missions, and formed the Alliance of Sahel States (AES) in September 2023. By early 2026, the AES functions as a mutual defense pact with coordinated border operations.
The juntas frame their break with France and ECOWAS as a sovereignty restoration project. In practice, they have replaced Western security partnerships with Russian military advisors, drone operators, and intelligence support. Russia's Africa Corps — the state-controlled successor to the Wagner Group — maintains an estimated 3,000 personnel across the three countries.
Jihadist expansion despite military operations
Despite large-scale military operations by junta forces and Russian advisors, jihadist groups have expanded their operational reach. JNIM (Jama'at Nusrat al-Islam wal-Muslimin), the al-Qaeda affiliate, controls significant territory in central Mali, northern Burkina Faso, and parts of western Niger. ISGS (Islamic State in the Greater Sahara) operates along the tri-border area and has pushed deeper into Burkina Faso's eastern provinces.
The insurgents exploit a pattern that repeats across the region: military forces clear towns and major roads, but lack the manpower to hold territory or protect rural communities. Jihadist governance structures fill the vacuum, providing basic dispute resolution, taxing trade routes, and recruiting from marginalized communities.
- ACLED data shows a 40 percent increase in violent incidents across the Sahel in the first quarter of 2026 compared to the same period in 2025.
- Burkina Faso has lost effective control of an estimated 60 percent of its national territory.
- JNIM has established parallel governance structures in over 200 communes across Mali and Burkina Faso.
Humanitarian emergency without cameras
The humanitarian situation across the Sahel has reached crisis levels that receive a fraction of the international attention directed at other conflicts. Over 4 million people are internally displaced across Mali, Niger, and Burkina Faso — a figure that has doubled since 2023.
Food insecurity affects an estimated 12 million people in the region, driven by a combination of conflict-related displacement, climate variability, and disrupted trade routes. The expulsion of international NGOs from parts of northern Mali and Burkina Faso has created information blackouts in areas with the greatest need.
- WFP reports that 2.5 million children under five face acute malnutrition in the three AES countries.
- Health facilities in conflict-affected areas operate at 30 percent capacity due to staff shortages and supply disruptions.
- School closures affect 1.8 million children across the region, with entire provinces without functioning education systems.
Russia's role: regime security, not counterinsurgency
Russia's Africa Corps provides the juntas with what they value most: regime security. Russian personnel guard presidential compounds, train elite units, and operate surveillance drones in capital cities. However, their effectiveness in the rural counterinsurgency campaign has been limited.
Reports from central Mali suggest that Russian-led operations prioritize resource extraction security — particularly gold mining areas — over population protection. Human rights organizations have documented civilian casualties in Russian-assisted operations, echoing patterns established by Wagner in the Central African Republic and Libya.
What comes next
The Sahel's trajectory points toward deeper fragmentation. The AES juntas have no transition timelines toward civilian rule, jihadist groups continue to expand, and the humanitarian system is losing access to populations in greatest need. International leverage is limited — the juntas have shown they can sustain power without Western approval, and neither China nor Russia conditions support on governance standards.
For the broader region, the key risk is contagion. Jihadist networks are already active in northern Ghana, Togo, and Benin. If the Sahel's security vacuum deepens further, the coastal states of West Africa face growing pressure on their own northern borders.
