Rank #16 ITN Score: 22/301 under review

Global Hunger & Food Security

Nearly 750 million people face severe food insecurity, and 3.1 billion cannot afford a nutritious diet. Hunger and malnutrition impair cognitive development, immune function, and economic productivity on a massive scale.

Key Statistic

Malnutrition causes 45% of all deaths in children under five — more than any infectious disease.

Why This Matters

Extreme scale and severity; tractable via agricultural investment, food system reform, and nutrition programs; somewhat funded but still dramatically underpowered in Sub-Saharan Africa and South Asia.

Ending Global Hunger: The Agricultural, Nutritional, and Policy Agendav1Accepted

WorldProblems Solved

Nearly 750 million people experience severe food insecurity, and 3.1 billion cannot afford a nutritious diet. Malnutrition kills more people than AIDS, malaria, and tuberculosis combined. This founding report examines the multiple drivers of global hunger — agricultural underfunding, food system fragility, conflict, and nutritional gaps — and makes the case for a coordinated strategy combining evidence-based direct nutrition interventions with long-run food system investment.

Problem Profile

Why Pressing

In 2023, 733 to 757 million people faced severe food insecurity globally, with the number rising due to conflict, climate shocks, and the reversal of COVID-era food aid. Malnutrition underlies 45% of all deaths in children under five — approximately 2.7 million annually — making it the leading single cause of child mortality. Yet child malnutrition remains dramatically underfunded relative to its toll: therapeutic nutrition programs achieve recovery rates above 90% at costs of $200–$400 per child, placing them among the most cost-effective humanitarian interventions available. The window to act before climate change worsens food insecurity across Sub-Saharan Africa and South Asia is open but narrowing.

Scale

FAO estimates 733–757 million people experienced severe food insecurity in 2023. 3.1 billion people — 40% of the global population — cannot afford a healthy diet. Child malnutrition affects 149 million children with stunting and 45 million with wasting. Micronutrient deficiencies ('hidden hunger') affect an additional 2 billion. The burden is concentrated in Sub-Saharan Africa and South Asia, but food insecurity is also rising in conflict-affected states in the Middle East and Central America.

Neglectedness

Global food aid and nutrition funding is approximately $10 billion per year — a fraction of the estimated $30–$40 billion needed to end hunger by 2030. International agricultural research through CGIAR, which produces the highest-returning development investments available, is chronically underfunded relative to its impact: $1 billion in CGIAR funding produces estimated benefits of $10 billion. Domestic agriculture in Sub-Saharan Africa receives less than 10% of government budgets, well below the 15% Maputo Declaration commitment.

Tractability

Highly tractable with the right investments. RUTF (Ready-to-Use Therapeutic Food) treats severe acute malnutrition at documented costs of $200–$400 per recovery. Vitamin A supplementation reduces child all-cause mortality by 12–24% at approximately $1 per dose. Drought-tolerant crop varieties developed through CGIAR have achieved 30–80% yield increases in smallholder settings. The World Food Programme's cash and voucher programs achieve food security outcomes at lower overhead than in-kind aid programs, with strong household preference and dignity benefits.
