🗺️ Where Is Food Insecurity Worst — and Why?

The geography of hunger is not random. It clusters predictably in places where multiple pressures overlap: poverty, conflict, climate vulnerability, and governance failures all compound each other. The Global Hunger Index consistently identifies a core belt of severe food insecurity stretching across sub-Saharan Africa and South Asia — with the world's most acute crises in conflict-riven countries like Yemen, South Sudan, Somalia, and the Democratic Republic of Congo.

Roughly 60% of the world's hungry people live in conflict-affected countries. This statistic matters enormously: conflict destroys crops, forces farmers off their land, disrupts supply chains, prevents food aid from reaching civilians, and redirects government resources away from agriculture. In Yemen, a civil war that began in 2015 had pushed 21 million people — out of a population of 30 million — into food insecurity by 2023. A child dies of starvation-related causes in Yemen roughly every 10 minutes.

But conflict is not the only driver. The cause-chain for food insecurity involves multiple pressures that reinforce each other:

Population growth — The global population is projected to reach 9.7 billion by 2050 and 10.4 billion by 2100. Sub-Saharan Africa's population is expected to double to 2.5 billion by 2050. More mouths require more food from land that is not expanding — in fact it is shrinking through degradation.
Climate change — Rising temperatures reduce crop yields through heat stress, altered rainfall, and more frequent extreme weather. A 2°C global temperature rise could reduce crop yields in sub-Saharan Africa by up to 20%. The regions most affected by climate change are also the ones with the least capacity to adapt.
Water scarcity — Agriculture accounts for 70% of all freshwater withdrawals globally. In water-stressed regions, declining groundwater tables and shrinking rivers reduce the amount of land that can be irrigated. The Sahel region of West Africa depends on erratic seasonal rainfall — a failed rainy season means a failed harvest.
Soil degradation — Intensive farming, overgrazing, and deforestation degrade soil quality. The United Nations estimates that a third of the world's topsoil is already degraded, and the world loses soil to erosion roughly 100 times faster than natural processes can replenish it. Degraded soil produces lower yields even with the same amount of rainfall and labour.
Environmental shocks — Pest outbreaks can devastate food supplies. Between 2019 and 2021, swarms of desert locusts swept across East Africa, the Horn of Africa, and South Asia in what the FAO called "the worst locust crisis in decades." A single swarm of 40 billion locusts can consume enough food in a day to feed 35,000 people. Across 10 countries including Ethiopia, Kenya, Somalia, and Pakistan, crops and pasture were destroyed across millions of hectares.
Result: food supply cannot keep up with demand — not because the world lacks technical capacity to produce food, but because the regions with the fastest population growth face the worst combination of climate stress, water scarcity, soil degradation, and political instability.
