The World Health Organization’s latest situation report shows how food insecurity in the Greater Horn of Africa has become a combined nutrition, disease and health-system emergency. More than 37.8 million people are experiencing or projected to experience acute food insecurity across the countries covered by the response, while more than 4.9 million children are projected to suffer acute malnutrition.
What WHO’s situation report shows
WHO classifies the crisis as a Grade 2 emergency affecting six countries across its African and Eastern Mediterranean regions. More than 1.5 million children are projected to require treatment for severe acute malnutrition. WHO notes that the regional burden is likely higher because comparable national estimates were not available for Ethiopia.
The crisis is driven by overlapping pressures: conflict, climate shocks, displacement, disease outbreaks, economic stress, fragile health systems and restricted humanitarian access. These factors reinforce one another rather than operating as separate emergencies.
Why food insecurity becomes a health emergency
Malnutrition increases vulnerability to disease
Children with acute malnutrition face elevated health risks, while outbreaks and disrupted services make early detection and treatment harder. Pregnant and lactating women, displaced people, refugees, pastoralist communities and people in insecure areas face particular barriers.
Access failures compound clinical risk
Families may be unable to reach facilities because of insecurity, transport costs or displacement. Health services can also face shortages of staff, medicines, nutrition supplies and stabilization-centre capacity.
Fragmented programmes miss the combined problem
A food-distribution intervention disconnected from health screening, surveillance, water and sanitation, protection and referral systems may fail to identify people at greatest risk. Integrated delivery is essential.
Operational priorities for humanitarian organizations
- Combine food-security, nutrition, health, WASH and protection analysis.
- Use early-warning data to anticipate outbreaks and nutrition caseloads.
- Strengthen referral pathways for severe acute malnutrition with medical complications.
- Pre-position medicines and nutrition supplies before access deteriorates.
- Protect continuity of essential maternal, child and primary healthcare.
- Work with local organizations and communities to identify access barriers and changing risks.
- Monitor who is being missed, not only how many services are delivered.
The financing and management gap
WHO estimates that approximately US$25.4 million is required for priority health and nutrition interventions from July through December 2026. Funding needs include emergency coordination, surveillance, outbreak response, essential services and operational support.
Effective delivery requires practitioners who understand nutrition assessment, food-security programming, public health and monitoring in emergencies. ATI’s Diploma in Food Security and Nutrition in Humanitarian Emergencies builds these integrated programme-management skills.
Key takeaway
The Horn crisis cannot be managed as hunger alone. The strongest response will connect nutrition treatment, disease surveillance, essential healthcare, WASH, protection and locally informed access planning while using shared evidence to adapt quickly.
