School meals link hunger relief to learning and local economies

School meal programmes sit at the intersection of household hardship and national development. A daily meal can feed a child, make school attendance more attractive and create a market for food producers. Evidence from research and government procurement rules raises a wider question: how far do budgets capture the benefits beyond the lunch served today?
The World Food Programme (WFP) estimates that at least 466 million children received school meals worldwide in 2024, according to its report published in September 2025. Yet primary-school coverage was 27 per cent in low-income countries, compared with 80 per cent in high-income countries. Expansion has not removed this income divide. The figures also challenge any assumption that school feeding remains predominantly emergency aid: these are large, established public programmes.
Attendance and learning are distinct outcomes
A 2021 systematic review led by Dongqing Wang examined 57 articles reporting school feeding interventions in low- and middle-income countries. Its pooled attendance analysis, based on three studies, found an increase of about 2.6 percentage points in the share of possible school days attended, compared with control groups. This pooled estimate does not imply that every child gains the same number of days.
The review found modest gains in height and weight, but no statistically significant pooled effect on mathematical or arithmetic skills. Many included studies had a high risk of bias. School attendance and learning therefore remain distinct outcomes: more time in a classroom creates an opportunity to learn, without establishing that teaching quality or achievement automatically improves.
A government programme in Ghana provides more direct evidence of educational effects. A randomised evaluation by Elisabetta Aurino and colleagues, published in 2023 and documented by the University of Ghana, found moderate average improvements in mathematics and literacy scores after two years. Gains were larger for girls and disadvantaged children and regions. The authors identified schooling, cognition and nutrition as suggestive mechanisms, rather than conclusively separating each pathway.
The Ghana findings indicate that a programme reaching boys and girls can reduce some educational disadvantages, with larger learning gains for girls and disadvantaged groups. They do not establish that feeding alone removes all barriers to education, nor that results transfer unchanged to every country.
Concentration is another proposed benefit that calls for care. WFP identifies improved concentration as a potential educational benefit of school meals, but attention, test scores and long-term attainment are different outcomes. The evidence reviewed here does not supply a universal effect size for concentration. A meal programme also operates alongside teachers, lessons and the conditions children face outside school.
A transfer to the household
For family finances, the immediate mechanism is straightforward. When a free school meal replaces food a household would otherwise buy, it releases money for other uses. When it supplies food that the family could not afford, its contribution is additional consumption. Both can matter for welfare, but only the first necessarily appears as a reduction in household expenditure.
Those distinctions complicate claims about poverty reduction. The value of the meal, the number of participating children and the days it is reliably served determine the scale of the transfer. A term-time service leaves weekends and holidays uncovered. Meal charges, travel costs or interrupted provision can change the net benefit. A programme's public cost is not identical to the cash saved by a family.
Over longer periods, improved schooling could influence economic prospects. That is a potential pathway from school feeding programmes to poverty reduction, rather than proof of a guaranteed rise in lifetime earnings. The Ghana trial measured learning over two years; it did not follow participants through their working lives. Immediate food support and projected future income belong to different parts of the evidence.
Local purchasing changes the transaction
Brazil's procurement system shows how feeding can connect children with agricultural policy. Guidance updated in April 2026 by the National Fund for Education Development (FNDE) states that at least 45 per cent of its federal transfers to the National School Feeding Programme (PNAE) must purchase food from family farming through a dedicated public call. This is a funding requirement, not a finding that every local authority has achieved it.
The guidance prioritises local suppliers before progressively widening the geographical search when supply is insufficient. Prices account for delivery conditions and seasonality; selection is not simply a lowest-price contest. These arrangements give local food procurement an explicit place in school feeding. They do not by themselves demonstrate higher farm profits or lower environmental impacts.
A school contract can offer a recurring buyer, while delivery schedules and food-safety requirements affect which producers can participate. Revenue is not profit: transport, packaging and production costs remain relevant. The central implementation question is whether smaller suppliers can fulfil contracts and receive payment without taking on costs that outweigh the gains. Local purchasing and reliable meals depend on the same delivery system.
The budget boundary
A 2024 analysis led by Linda Schultz examined 51 comparable assessments conducted from 2012 to 2021 across 45 countries using the World Bank's SABER school feeding policy tool. It identified programme design, implementation and fiscal space among the weakest policy areas, and found that coordination across sectors remained nascent in low-income settings. These are assessments of policy systems at different dates, rather than experimental measurements of children's outcomes or a current snapshot of national programmes.
The authors argue for domestic funding and complementary services as part of broader investment in human capital. Their position highlights how benefits can span education, nutrition, social protection and agriculture, while purchasing and running meals require identifiable funding. In Brazil, FNDE guidance specifies that its federal PNAE transfers fund food purchases, while operational expenses are financed from the implementing authorities' own resources.
The welfare-versus-investment distinction is also changing. WFP describes governments increasingly treating school meals as a nationally owned policy connecting children's development with food systems. The evidence therefore does not support a universal claim that governments ignore their longer-term value. It points instead to uneven coverage and a gap between multisectoral ambitions and delivery capacity.
The connection to SDG 4 (Quality Education) is practical: nutrition support can help children attend school and, in some evaluated settings, improve learning. Whether school meals rank among the most effective purchases available to a particular government remains a question of costs, alternatives and implementation. Their effects can reach beyond hunger relief, but the evidence reviewed here does not yield a single global ranking of social policies.
