Hunger persists across parts of Africa not because the continent can’t produce food, but because a web of reinforcing crises, from armed conflict to climate shocks to broken supply chains, keeps food from reaching the people who need it. As of early 2025, more than 48 million people across just nine southern African countries were experiencing crisis-level food insecurity, and the Democratic Republic of the Congo alone had 27.7 million people going hungry. The causes are specific, measurable, and mostly man-made.
Armed Conflict Destroys Food Systems
War is the single largest driver of acute hunger on the continent. In 2025, six countries or territories were flagged for catastrophic food insecurity: Sudan, South Sudan, Gaza, Yemen, Haiti, and Mali. In every one of them, conflict was the primary cause. South Sudan’s Upper Nile state is at risk of outright famine due to escalating violence and economic collapse.
Conflict doesn’t just kill crops in the ground. It dismantles the entire system that moves food from farms to mouths. In Ethiopia’s Amhara region, fighting destroyed agricultural infrastructure, displaced over half a million people, and wiped out an estimated 14 million quintals of agricultural production, roughly $500 million in damage. More than 5.5 million people in that region alone fell into acute food insecurity. When farmers flee their land, markets shut down, roads become impassable, and the health and water systems that keep communities functional collapse alongside the food supply.
Climate Shocks Hit the Most Vulnerable Crops
Africa contributes the least to global emissions but absorbs some of the worst climate impacts. Droughts have reduced national cereal production by 9 to 10 percent on average across affected countries, and that figure masks sharper losses in specific crops. Maize, a dietary staple for hundreds of millions of people, is particularly sensitive to drought. Coffee, a critical cash crop that funds food imports, is also heavily affected because the plant depends on consistent water availability.
These aren’t occasional disasters. Drought and flood cycles are becoming more frequent and less predictable, making it harder for smallholder farmers to plan planting seasons or invest in next year’s harvest. When a drought wipes out a season’s crops, families eat through their savings and seed stock, which means even a good rainy season the following year starts from a deficit.
Families Spend Half Their Income on Food
In Sub-Saharan Africa, households spend 40 to 50 percent of their budgets on food. Compare that to roughly 10 percent in the United States or Western Europe. This means any spike in food prices immediately translates into skipped meals. The region has experienced the highest food price inflation of any global region in recent years, squeezing families who were already spending nearly everything they earned just to eat.
Global disruptions make this worse. Africa imports significant quantities of wheat, other grains, and fertilizer from Russia and Ukraine. When Russia invaded Ukraine, grain exports dropped and trade costs rose, pushing local wheat prices higher across the continent. The pain wasn’t evenly distributed. Countries most dependent on Black Sea grain corridors saw the sharpest price spikes, and urban poor communities were hit hardest because they buy nearly all their food rather than growing it.
Half the Harvest Never Reaches a Plate
Sub-Saharan Africa loses up to 50 percent of its fruits and vegetables before they ever reach a consumer. In Ghana, losses range from 30 to 50 percent across the supply chain. In Ethiopia, post-harvest handling alone accounts for nearly 86 percent of total food losses, with storage and marketing making up the rest. The reasons are straightforward: a lack of cold storage, poor roads, limited packaging, and long distances between farms and markets in tropical heat.
This is food that was successfully grown, harvested, and is sitting in someone’s hands, yet it rots before anyone can eat it. Solving post-harvest loss wouldn’t require growing a single additional calorie. It would require refrigerated trucks, better warehouses, and roads that don’t wash out in the rainy season.
Depleted Soil, Minimal Fertilizer
African farmers work with far less than their counterparts elsewhere. In 2022, Sub-Saharan Africa used just 18.2 kilograms of fertilizer per hectare of farmland. The global average is roughly six times that. Without adequate fertilizer, soils that have been farmed for generations produce lower and lower yields. Farmers who can’t afford fertilizer also typically can’t afford improved seeds, irrigation, or pest control, compounding the productivity gap.
The result is that many African farms produce a fraction of what the same land could yield with basic inputs. This isn’t a matter of farming skill. It’s a matter of access and cost. Fertilizer prices spiked after the Ukraine war disrupted global supply chains, pushing an already expensive input further out of reach for smallholder farmers.
Humanitarian Funding Is Shrinking
The World Food Programme, the largest humanitarian organization fighting hunger, needs $16.9 billion in 2025 to meet current demand. It expects to receive about $6.4 billion, a 40 percent drop from its $10 billion budget in 2024. That gap means millions of people who were receiving food assistance will see rations cut or eliminated entirely, at a moment when the number of hungry people is growing.
Aid was never designed to be a permanent solution, but it serves as a lifeline during acute crises. When funding drops while conflict and climate shocks intensify, the safety net disappears for the most vulnerable populations: children, pregnant women, and displaced families who have no other source of food.
What Hunger Does to a Generation
The consequences of food insecurity go far beyond empty stomachs. Children who don’t get enough food over months and years develop stunting, meaning their bodies and brains don’t grow to their full potential. Stunted children perform worse in school, earn less as adults, and are more likely to get sick. Women who were stunted as children face higher risks of complications during childbirth and are more likely to deliver low-birth-weight babies, passing nutritional disadvantage to the next generation.
Acute malnutrition, or wasting, is more immediately dangerous. Children whose weight drops too low relative to their height have weakened immune systems, making common infections like diarrhea potentially fatal. Across the countries experiencing the worst food crises, wasting and stunting rates remain among the highest in the world, locking communities into cycles where today’s hungry children become tomorrow’s less productive adults, less able to withstand the next drought or conflict.
Why These Problems Reinforce Each Other
No single factor explains hunger in Africa. What makes the crisis so persistent is that these drivers feed into one another. Conflict displaces farmers, which reduces food production, which raises prices, which deepens poverty, which makes communities less resilient to the next drought. Climate shocks destroy harvests, which increases competition for scarce resources, which can fuel further conflict. Weak infrastructure means that even in peaceful, well-watered regions, a significant share of food never makes it from the field to the family that needs it.
Breaking these cycles requires action on multiple fronts simultaneously: resolving or containing armed conflicts, investing in roads and cold storage, making fertilizer affordable, and maintaining humanitarian funding during acute crises. The food itself is not the fundamental problem. Africa has the arable land, the water resources, and the farming knowledge to feed its population. What it lacks, in too many places, is the stability, infrastructure, and investment to turn that potential into reliable meals.
