Horn of Africa Locusts and Crop Pests — 2026-09-27
This week's story is not locusts themselves but the gathering storm around them: an El Niño season bringing below-average Deyr rains and floods, and officials urging farmers to activate pest surveillance ahead of possible migratory pest upsurges. Food security agencies confirmed Somalia's Crisis continues and Ethiopia's main harvest may fall far below average, shrinking the buffer against any future locust or fall armyworm shock.
Horn of Africa Locusts and Crop Pests — 2026-09-27
Top developments
Kenya: farmers urged to step up pest surveillance before the short rains
Kenyan agricultural officials and media urged farmers this week to activate pest surveillance and early-warning systems as the October–December rainfall season approaches, specifically flagging migratory pests such as desert locusts and African armyworm as risks under El Niño conditions. The Eastleigh Voice similarly advised farmers to protect crops and livestock against El Niño risks, with pest monitoring for desert locusts a central recommendation. This matters for swarm forecasting: warm, wet conditions during the Deyr season are the classic trigger for breeding that produces hopper bands in the following cycle.
Somalia: hunger crisis deepens as floods and funding gaps loom
On 23 September 2026, the Federal Government of Somalia and the UN warned that millions face high hunger levels and that child acute malnutrition is projected to worsen, with heavy flooding tied to the anticipated El Niño and serious funding shortfalls compounding the situation. WFP issued a matching warning that hunger and malnutrition crises persist in Somalia as projected floods and funding shortfalls threaten vulnerable populations. A population already in food stress has very little resilience left if locusts or armyworm strike standing Deyr crops; FEWS NET's August 2026 update for Somalia noted that despite better-than-anticipated xagaa rains, a risk of Famine (IPC Phase 5) persists.
Somali media have also flagged the seasonal risk ahead: Dawan reported Somalia has approved its El Niño 2026–2027 response plan, while SODMA earlier issued a hazard warning for heavy rains and flooding expected in October, November and December 2026 across 29 cities.
Ethiopia: meher harvest forecast sharply below average
FEWS NET assessment reported mid-September that Ethiopia's meher harvest could be up to 30% below average after the poorest kiremt rains on record, in a strong El Niño year. A weak main-season harvest means large areas of stressed, late-developing cropland — conditions that can concentrate pests and heighten harvest-loss risk if fall armyworm pressure rises during maturation.
Regional alarm: 40.3 million hungry across Eastern Africa
IGAD's new regional report, published 24 September 2026, warns that 40.3 million people face hunger as Eastern Africa battles conflict and climate shocks, and calls for a shift from emergency relief to long-term resilience. The JRC similarly reported on 21 September 2026 that acute food insecurity remains alarmingly high globally, with El Niño and funding cuts deepening risks in the coming months. These figures frame why even a modest locust escalation would have outsized humanitarian consequences.
Local view
Kenyan outlets dominate this week's local coverage. The Star reported farmers being told directly to "step up pest surveillance during El Niño" as the short-rains season approaches. The Eastleigh Voice, based in Nairobi's Eastleigh business district, framed pest monitoring as one of the core practical steps for farmers facing compounding El Niño threats. No fresh Somali or Amharic-language locust reporting from the past week was found; recent Somali coverage focuses on flooding preparedness rather than an active locust invasion.
Context & numbers
- 40.3 million people face hunger in Eastern Africa per IGAD's latest regional report
- Up to 30% below-average meher harvest forecast for Ethiopia after record-poor kiremt rains
- October–December (Deyr) short rains season begins next month — the key pest-breeding and flood-risk window, with 29 Somali cities on flood alert
- For reference on control capacity, FAO's February 2026 bulletin recorded 34,564 ha treated regionally in February versus 47,358 ha in January
On the radar
- Deyr season onset (October): watch for any hopper band detection reports once rains establish in Somalia and eastern Ethiopia; SODMA's flood warning covering 29 cities also doubles as a proxy for breeding-habitat expansion
- Ethiopia meher harvest assessments (November–December): fall armyworm pressure on late maturing maize will feed into final loss estimates following the 30% below-average forecast
- Funding appeals: WFP and the UN have flagged Somalia funding shortfalls; additional drought/pest contingency appeals may follow once Deyr outcomes are clearer
- Fall armyworm monitoring: no new Horn-specific FAW outbreak reports this week; seasonal surveillance advisories in Kenya suggest officials are watching for escalation
