Executive summary

The Lake Chad Basin remains a four-country insurgency theatre in which faction competition, not state pressure alone, shapes the pattern of violence against civilians and aid actors.

Islamic State West Africa Province operates a quasi-governance model in parts of the basin, taxation, dispute resolution, market regulation, which makes access negotiation both possible and politically fraught.

The multinational response has been weakened by force withdrawals and coordination gaps; humanitarian actors should assume slower and less predictable military response than in previous years.

Full report

Actors and dynamics

ISWAP's approach to civilians is calculated and administrative; the Jama'atu Ahlis Sunna faction's is more indiscriminate. The distinction matters operationally because it changes what negotiated access is worth and how predictable local conditions are.

Security force posture is garrison-based, which concentrates protection into towns and leaves corridors between them contested. Movement between garrisons is the defining risk of the theatre.

Humanitarian operations

Distinguish clearly between military-escorted logistics and independent humanitarian movement; conflating the two has direct consequences for acceptance and for staff safety in the event of an attack on the escort.

Maintain rehearsed hibernation and relocation plans at every field site, with realistic stock, communications redundancy and a named decision-maker for suspension.

Indicators and warnings

Escalation: overrun of a garrison position; increased use of drones by armed groups; abduction of international staff; suspension of the multinational joint force contribution by a member state; large-scale forced returns.

De-escalation: sustained reopening of the Maiduguri–Damaturu and Diffa corridors; verified defector reintegration at scale; return of commercial market activity to lakeshore communities.

Key findings

  • Attacks on military positions have periodically produced weapons capture that directly increases capability against soft targets, including humanitarian premises.
  • Garrison-town operating models place aid actors inside military perimeters, creating acceptance problems that persist long after any single incident.
  • Abduction of aid workers is a demonstrated tactic with both financial and propaganda objectives.
  • Displacement across the Nigeria–Niger–Cameroon–Chad borders is cyclical and responsive to both violence and forced returns policy.
  • Lake level variation and farmer–herder competition are structural drivers that will outlast the current insurgency configuration.

Analyst assessment

We assess with high confidence that insurgent capability in the basin will persist through 2027 without decisive military resolution.

We assess with moderate confidence that aid worker abduction incidents will continue at a low but non-zero annual rate, with road movement outside garrison towns as the principal vector.

Forced or premature return of displaced populations is the most likely trigger for a rapid deterioration in humanitarian conditions.
