Sahel migration route

What it is

The Sahel migration route is the overland corridor linking West and Central Africa to North Africa and, via the Central Mediterranean, to southern Europe. Its central choke point is Agadez, in northern Niger, where Saharan guide networks, fuel depots, and vehicle fleets convert subsistence migration into a structured economy. The route's main axis runs from coastal West Africa (Senegal, Guinea, Nigeria, Côte d'Ivoire) toward Agadez, then north across the Sahara through the Sébaïha pass to Sabha in southern Libya, and onward to Tripoli, Zuwara, or Misrata for Mediterranean departures. A secondary branch diverges northwest through Algeria and Morocco to Spain. Players include individual migrants, Tuareg and Toubou smuggling networks, armed groups that tax convoys, Libyan coast-guard factions that intercept or profit from departures, and European Union agencies that fund interception and returns.

History

Agadez has been a trans-Saharan transit point for centuries, but the modern migration economy dates to the 1990s, when prolonged drought and the collapse of Saharan tourism pushed Tuareg guides toward people-carrying. Flows accelerated sharply after Libya's 2011 collapse removed the Gaddafi government's bilateral deterrence deals with Italy and the EU. By 2016, an estimated 330,000 people transited through Agadez annually, roughly 5,000 per week, the majority headed for Libya.

European pressure prompted Niger to adopt Law 2015-36 in May 2015, criminalizing migrant smuggling. Enforcement began in mid-2016, backed by approximately €247.5 million directed through the EU Emergency Trust Fund for Africa. Recorded transits fell from 333,891 in 2016 to 69,430 in 2017. But enforcement drove networks underground: journey prices from Agadez to Libya rose fourfold, routes shifted to remote desert bypasses with higher mortality, and the migration economy, which had provided direct livelihoods to at least 6,565 people in Agadez, pivoted toward artisanal gold mining and other informal activity.

Current state

Niger's military junta (the CNSP, which seized power in July 2023) repealed Law 2015-36 in December 2023 and simultaneously expelled the EU's EUCAP Sahel Niger mission. IOM recorded a 94 percent increase in crossings from Niger into Libya between December 2023 and January 2024. As of early 2026, IOM's Displacement Tracking Matrix counts 936,134 migrants in Libya; among sub-Saharan nationals, Nigeriens account for 54 percent, Chadians 23 percent, and Nigerians 8 percent. The Central Mediterranean crossing from Libya and Tunisia to Italy and Malta documented 1,340 deaths in 2025; the Sahara killed or caused the disappearance of at least 259 people in the first five months of 2025 alone. In the first half of 2026, Central Mediterranean fatalities rose roughly 150 percent year-on-year even as total arrivals to Italy declined, indicating the crossing is becoming deadlier per attempt.

Relationships

The Sahel route runs through active conflict zones along its full length, as tracked in Sahel Insurgency. JNIM controls territory in Mali and Burkina Faso that migrants must cross or circumvent, and ISGS affiliates in Niger's Tillabéri and Tahoua regions levy informal tolls on transport convoys, a revenue stream linked to jihadist financing through gold and smuggling networks. The 2023 coups in Niger, Mali, and Burkina Faso dissolved the EU's counter-migration architecture simultaneously. Air France's June 2026 exit from Bamako marks the end of French commercial aviation in the Sahel, itself a symptom of the same rupture.

Sudan's civil war since April 2023 has diverted Sudanese migrants westward through Chad toward Agadez, adding a major new flow to existing West African streams. Libya's factional fragmentation, tracked in 利比亚三大对立议会签署联合选举路线图，目标2027年2月, means departure-point control shifts between rival armed groups, leaving the EU with no stable interlocutor for a replacement border agreement.

What to watch

• Whether Niger's junta imposes new migration controls as leverage in renegotiating European development aid and sanctions relief
• Libya's coast guard funding and capacity, which directly determines interception rates and offshore fatality counts on the Central Mediterranean leg
• Chad as an emerging bypass node: Sudanese and Central African flows are routing through Chadian corridors toward Sebha as Niger's main route re-activates
• EU talks with Tunisia, Libya, and Egypt on a post-Niger migration framework, which so far lack the enforcement architecture that made the Niger arrangement viable
• Whether UNHCR and IOM legal pathway expansions can pull meaningful demand away from the desert route
