Food Burden Threatens Basic Needs for Africa's Poorest by 2050

Projections show Africa's poorest 10% could spend over half their income on food by 2050, widening hunger gaps.

By 2050, the Global Change Analysis Model (GCAM) projects the poorest 10% in Western Africa may spend up to 48.4% of their income on food, while Eastern Africa's poorest 10% could spend 42.5% and Southern Africa's poorest 10% up to 49.6%. In Southern Africa, the richest 10% may spend just 5.5% of their income on food by that year. The range of food burden for Western Africa's poorest 10% spans 18.5% to 77.5% by 2050. These figures emerge from 3,735 scenarios across 32 geopolitical regions analyzed by researchers at MIT and Tulane University, published in *Earth's Future* (2026). The model assesses how income, land use, energy systems, water availability, and consumer behavior shape resource security—defined as access to food, energy, and water.

This projection reflects median outcomes across multiple plausible futures, not a single most probable path. Regional averages obscure extreme outcomes for specific income groups, and the study does not quantify climate change mitigation costs beyond land use scenarios. The findings highlight how resource insecurity could deepen hunger and poverty for millions if food becomes unaffordable relative to income.

For abundance, this means basic food security becomes increasingly gated for the poorest in Africa by 2050. If food burden rises beyond 50% of income, hunger and poverty risk escalating without targeted interventions. The next critical watch point is whether regional policies address the factors identified—land use, water access, and energy systems—to prevent food becoming a barrier to survival rather than a basic need. The study’s caveats confirm this remains a range of plausible futures, not a fixed outcome.
