The porous and largely ungoverned borders that crisscross the Sahel region are quickly becoming highways for criminal enterprises and extremist insurgencies. Stretching across Mali, Niger, and Burkina Faso, these frontiers—once dotted with nomadic herder trails—are now used by drug traffickers, arms smugglers, and jihadist groups who exploit the lack of coordination among states.
In recent months, intelligence sources have reported a surge in cross-border attacks, especially in Niger’s Tillabéri region and northern Burkina Faso. According to the Armed Conflict Location & Event Data Project (ACLED), nearly 60% of militant incidents in the region this year occurred within 30 kilometers of national borders.
The Sahel’s Fragile Geography
The borders between the Sahelian nations are often nothing more than lines on a map. In reality, these regions are marked by vast deserts, sparse security presence, and overlapping ethnic and tribal allegiances that span countries. The Tuareg, Fulani, and Tebu communities, for example, maintain cross-border kinship and trade ties that long predate the modern state system.
“This region was never designed for rigid national borders,” explains Dr. Awa Diop, a political geographer at Dakar University. “But now, non-state actors are weaponizing that historical openness.”
A Gateway for Illicit Networks
Criminal groups have turned these weak points into transit corridors for illicit goods. A recent UNODC report identified over 120 informal crossing points in Niger alone, many used for trafficking narcotics, fuel, and small arms. In Mali, reports suggest that extremist groups linked to both ISIS and al-Qaeda levy taxes on smugglers in exchange for safe passage through contested zones.
“It’s a mutually beneficial arrangement,” says Mamadou Traoré, a regional security analyst based in Bamako. “The jihadists get funding, and the traffickers get protection. Meanwhile, the state is absent.”
Militarization and Civilian Fallout
In response, countries in the G5 Sahel Joint Force have ramped up military patrols. However, the presence of foreign troops—especially French and Western forces—has sometimes fueled local resentment. Civilian deaths from mistaken airstrikes and heavy-handed operations have undermined state legitimacy in border communities.
“The enemy is the border itself,” says Colonel Abdoulaye Sanda, a Nigerien military officer. “We’re fighting shadows in terrain that doesn’t obey political boundaries.”
Local populations, often caught between militants and the military, are suffering. Entire villages have been abandoned. Markets have collapsed. Children no longer cross into neighboring towns to attend school or fetch supplies.

Toward a Pan-Sahel Border Strategy
Experts warn that unless Sahelian states rethink border governance, the situation will deteriorate. Solutions being discussed include:
-
Joint Border Patrol Units backed by ECOWAS.
-
Digital Border Monitoring using satellite imagery and AI-enabled drones.
-
Community Border Watch Programs that integrate local populations into surveillance and intelligence-sharing.
-
Legalizing Informal Crossings with biometric ID checkpoints to reduce corruption and improve regulation.
“If African countries continue to act in silos, the Sahel will keep bleeding,” warns Amina Ahmed, regional coordinator for the African Centre for Border Governance (AfCoBGov). “We need a unified strategy—not just fences and soldiers.”
The future of the Sahel depends not just on military might, but on political will. As criminal and extremist networks become more sophisticated, only a border security model built on cooperation, trust, and technology can hold the line.
