What happened
UNHCR and IOM reporting through 2026 has flagged a building set of displacement pressures across the Horn of Africa that, taken together, point toward a potentially significant new migration crisis. Sudan's civil war continues to generate large-scale displacement into Chad, Egypt, South Sudan and Ethiopia; Ethiopia's own internal conflict and drought dynamics continue to displace populations in Amhara, Oromia and Tigray; and Somalia's mix of conflict, drought cycles and clan violence continues to produce both internal displacement and outward migration pressure toward the Gulf, Yemen and, via established smuggling routes, toward Europe.
IOM's Missing Migrants Project and Mixed Migration Centre reporting have both flagged continued, and in some routes increasing, use of the eastern route across the Gulf of Aden toward Yemen and onward toward the Gulf states, alongside sustained flows along the central Mediterranean route originating in or transiting the Horn and East Africa.
Why it matters
The Horn's displacement dynamics are unusual in combining almost every major driver of forced migration simultaneously: active armed conflict in Sudan, Ethiopia and Somalia; climate-linked drought and flood cycles that have recurred with increasing frequency; and chronic economic fragility that limits absorption capacity in neighbouring host countries themselves under strain. This combination raises the probability of a compounding crisis in which host country capacity — already stretched in Chad, South Sudan, Kenya and Uganda — is overwhelmed by simultaneous large-scale displacement events rather than a single, sequential crisis that can be resourced and managed in turn.
The regional and international policy environment is also less favourable than in previous displacement crises: donor humanitarian funding has contracted, and several European and Gulf destination states have hardened migration policy, reducing the safety-valve function that migration to those destinations previously provided and potentially concentrating pressure within the region itself.
How the threat is evolving
The compounding risk is most visible at the intersection of Sudan and Chad, where continued Sudanese displacement into an already fragile Chadian host environment risks tipping local resource competition into communal conflict, a dynamic ACLED and Crisis Group reporting have both flagged as a growing concern. In the Somali and Ethiopian context, drought recurrence — following the historic 2020-2023 drought — combined with conflict-driven displacement is producing a layered vulnerability in which populations displaced once by conflict are displaced again by climate shocks, eroding coping capacity with each cycle. Smuggling networks along both the eastern (Gulf of Aden/Yemen) and northern (Libya/Mediterranean) routes remain well established and adaptive, continuing to move migrants despite periodic crackdowns.

Security implications
Large-scale, compounding displacement carries direct security implications for host communities and humanitarian operations alike, including elevated risk of resource-competition conflict in border areas, strain on camp and settlement security management, and the continued exploitation of displaced populations by smuggling and trafficking networks operating along established regional routes. Organisations operating in border regions should treat displacement trend data as a leading indicator of localised instability risk, not solely a programming metric.
The Horn is not facing a single migration crisis waiting to happen; it already has several running in parallel, and the risk is that donor and host-country capacity, calibrated to manage one crisis at a time, is overtaken by their convergence.
Business implications
Businesses operating in border regions and host communities across Chad, Kenya, Uganda and South Sudan should factor displacement-driven resource competition and infrastructure strain into local operating risk assessments, particularly around water, land and labour markets. Transport, logistics and telecommunications providers serving displacement-affected corridors may also see both increased demand and increased security exposure along key routes.
NGO/humanitarian implications
Agencies should plan for the possibility of simultaneous, rather than sequential, large-scale displacement events across the Horn, and should stress-test regional funding and logistics arrangements against a scenario in which Sudan, Ethiopia and Somalia displacement crises peak concurrently. Protection programming should also anticipate increased exploitation risk for migrants along both eastern and northern smuggling routes as legal migration pathways narrow.
- Stress-test regional response plans against concurrent, rather than sequential, displacement crises across Sudan, Ethiopia and Somalia.
- Expand protection programming addressing smuggling and trafficking exploitation along the eastern and northern migration routes.
- Engage host governments early on absorption capacity planning before displacement peaks overwhelm existing arrangements.
- Integrate climate and conflict displacement drivers into a single early-warning framework rather than tracking them separately.
