UNICEF’s El Niño Warning Puts 162 Million African Children in the Risk Zone

UNICEF’s warning that more than 162 million children in Eastern and Southern Africa are exposed to the strengthening 2026/2027 El Niño should be treated as a regional readiness test, not as a distant humanitarian forecast. The agency said on September 1 that more than two-thirds of children in the region live in areas likely to face drought, extreme heat, flooding or related shocks as the climate pattern intensifies. Kenyan outlet The Star carried the warning on September 2, underlining the urgency for governments to act before the worst impacts arrive.

The countries identified by UNICEF include Djibouti, Eritrea, Ethiopia, Kenya, Madagascar, Malawi, Mozambique, Somalia, South Sudan, Sudan, Uganda, Zambia and Zimbabwe. The risks vary by geography. East Africa faces an elevated threat of flooding during the short-rains season, while Southern Africa could face poor rainfall and harvest pressure. For children, those differences matter less than the common result: water systems become unreliable, food prices rise, clinics are strained, classrooms are disrupted and families are pushed into survival decisions.

UNICEF is seeking US$173 million within its existing 2026 Humanitarian Action for Children requirements to fund anticipatory and life-saving support across the 13 priority countries. The figure is not large when measured against the scale of exposure. It is a reminder that the region is again facing a predictable shock with a narrow window to prepare.

A predictable crisis

El Niño is a recurring climate pattern, but its impact is shaped by vulnerability, public services and preparedness. A heavy rainy season does not automatically become a disaster. A failed harvest does not automatically become a nutrition emergency. The difference is often whether governments and partners act early enough to protect water, health, schools, food systems and household income.

That is why UNICEF’s framing matters. The agency is not only warning that climate hazards are coming. It is warning that child-critical systems are already stretched. Across Eastern and Southern Africa, conflict, displacement, disease outbreaks, high food prices and debt pressure have reduced the margin for error. Families that used to cope with one bad season now face repeated shocks with fewer savings, weaker livestock holdings, less reliable work and disrupted access to services.

UNICEF’s regional appeal for 2026 says nearly 30 million children in Eastern and Southern Africa are already in urgent need of humanitarian assistance because of overlapping crises. The El Niño warning adds another layer to that stress. The policy question is not whether the region will experience climate volatility. It is whether public systems can prevent volatility from becoming a child survival emergency.

Nutrition will be the first pressure point

Nutrition is likely to be one of the earliest and clearest indicators of whether the response is working. Drought reduces crop output, weakens pastoral livelihoods and increases food prices. Flooding can destroy stored food, contaminate water and cut off access to markets. Extreme heat can worsen dehydration and disease risk. Children under five are especially exposed because their bodies have less tolerance for prolonged food and water stress.

UNICEF is calling for life-saving supplies to be pre-positioned and for early screening and treatment of malnutrition to expand. That is practical, not symbolic. Once severe acute malnutrition spreads, treatment becomes more expensive, mortality risk increases and health systems are forced into emergency mode. Early screening can identify children before they deteriorate. Pre-positioned therapeutic food and medical supplies can keep remote clinics functioning when roads become impassable.

The warning is particularly serious for places already affected by food insecurity and conflict. Somalia could see severe flooding scenarios affecting millions of people, while South Sudan faces a compound mix of drought, heat, localised flooding, malnutrition risk and displacement. Ethiopia, Sudan and parts of Southern Africa also enter this cycle with existing vulnerabilities. El Niño is not hitting a blank slate. It is hitting communities already managing unfinished crises.

Water and disease risks

Water, sanitation and hygiene systems are another critical front. Floods can contaminate water sources and latrines. Drought can force families to use unsafe water or travel farther to collect it. Both conditions increase the risk of disease outbreaks, including cholera and other waterborne illnesses. When clinics are already underfunded or understaffed, a climate shock can quickly become a health shock.

UNICEF’s recommended response includes stronger disease surveillance, vaccination campaigns, essential health services and safer water systems. This is where climate adaptation becomes concrete. It is not only about long-term emissions debates or future infrastructure plans. It is about whether boreholes work, whether water treatment supplies are available, whether community health workers can report disease early, and whether clinics can keep operating during flood or heat events.

For African governments, these are also budget and governance questions. Climate shocks expose the quality of maintenance, local planning and emergency coordination. A country can announce preparedness at national level while districts lack fuel, spare parts, medicines or reliable communication. The response must therefore move beyond capital-city statements and into operational readiness at school, clinic and community level.

Schools are part of the emergency system

Education should not be treated as secondary in an El Niño response. UNICEF and Dalberg warned earlier this year that climate-related disasters have already disrupted learning for 130 million children in Eastern and Southern Africa and caused major economic losses. When schools close because of floods, heat, water shortages or unsafe roads, children lose more than classroom time. Schools are often feeding points, protection spaces and gateways to social services.

Girls and children from poorer households usually carry the highest risk when education is interrupted. They may be asked to collect water, care for siblings, work, migrate with families or marry early under household economic pressure. A climate shock can therefore produce consequences that last well beyond one rainy season.

UNICEF’s call to reinforce school infrastructure and prepare alternative learning spaces is an important part of preparedness. So is linking schools to nutrition, health and protection services. Keeping children learning during a climate shock is not a luxury. It is part of protecting human capital and preventing a temporary emergency from becoming a long-term development setback.

The financing gap

The most concerning detail in UNICEF’s warning is the financing gap for anticipatory action. The agency says less than one percent of international humanitarian assistance is currently available for this kind of early action, even though acting before a crisis peaks saves lives and reduces later costs. UNICEF cites the wider disaster-risk evidence that every US$1 invested in prevention can save up to US$15 in recovery costs.

This gap is irrational but familiar. Donors often move faster when images of disaster are already visible. Governments also face political pressure to respond after a crisis rather than invest quietly before it. The problem is that children pay the price for delayed financing. By the time malnutrition is widespread, schools are closed and disease outbreaks are expanding, the response is more expensive and less effective.

Anticipatory action should include early cash support, supply pre-positioning, water-system repair, livestock and agricultural support, temporary learning plans and protection services. These measures are not experimental. The challenge is scale, timing and coordination. Funding after the damage is visible may satisfy emergency politics, but it is weaker public policy.

A continental signal

The El Niño warning has significance beyond the 13 priority countries. It shows how climate risk is becoming a core African development issue. Debt sustainability, food security, health, education, migration, conflict prevention and infrastructure resilience are increasingly connected through climate shocks. A drought can affect inflation. Flooding can disrupt trade routes. Heat can reduce labour productivity. School closures can reduce future earnings. Disease outbreaks can damage public finances and social trust.

African governments need stronger early-warning systems, but warnings must trigger decisions. Meteorological data should connect to finance ministries, education departments, health agencies, water authorities and local governments. Regional bodies should also treat climate preparedness as part of economic integration, because shocks often cross borders through food markets, displacement and disease.

The private sector has a role as well. Food distributors, telecoms operators, banks, insurers, logistics companies and energy providers all shape resilience. Mobile money can deliver emergency cash. Telecom networks can support alerts. Banks and insurers can help farmers manage risk. Energy providers can keep clinics and water systems running. Climate resilience is not only a humanitarian sector task.

The bottom line

UNICEF’s September warning is clear: the region knows which children are at risk, which hazards are likely and which interventions can reduce harm. The real test is whether governments, donors and partners act before the crisis becomes more visible and more expensive.

For Eastern and Southern Africa, El Niño is not just a weather event. It is a test of public systems, climate finance and political seriousness. If the region waits until floods, drought and heat have already disrupted homes, clinics and classrooms, the cost will be measured in malnutrition, disease, lost learning and deeper poverty. Acting early is the more disciplined choice, and for 162 million children, it may be the difference between a managed shock and a preventable emergency.
