Famine is one of the oldest killers in human history. For most of recorded civilization, a bad harvest, a drought, a blight, a war — any of these could translate into millions of deaths. Not hundreds. Not thousands. Millions.
The Bengal famine of 1943 killed between 2 and 3 million people. The Chinese famine of 1959–61 — the worst in recorded history — killed between 15 and 55 million, depending on which estimate you trust. The Ethiopian famine of 1983–85 killed between 400,000 and 1 million. These were not ancient tragedies. They happened within living memory.
Since 2000, major famines have killed tens of thousands, not millions. The scale of the catastrophe has compressed by more than 95%. A phenomenon that once periodically killed populations equivalent to modern major cities has been reduced — not eliminated, but reduced — to a fraction of its former lethality.
That change is one of the most underreported achievements in human history.
What Actually Changed
The Green Revolution is where the story begins, though not where it ends. In the 1960s and 1970s, agronomist Norman Borlaug and his colleagues developed high-yield varieties of wheat and rice that produced two to three times the grain per acre of traditional varieties. Applied across South Asia — India, Pakistan, Bangladesh — the Green Revolution transformed the food supply of a region that had seemed chronically on the verge of mass starvation.
India, which faced severe famine risk in the 1960s and required emergency food aid from the United States, became a net food exporter within two decades. Bangladesh, once cited as a nation that could never feed itself, achieved food self-sufficiency. The mechanism was not charity. It was agricultural science, irrigation infrastructure, fertilizer, improved seeds — all scaled through market-based adoption by farmers who could see the yields with their own eyes.
The global food supply per person has increased by 32% since 1961 — from roughly 2,200 kilocalories per day to 2,900 kilocalories per day — while the world population more than doubled. We grew more food per person even as there were far more people to feed. That is the core fact. Everything else follows from it.
The Numbers on Hunger
In 1990, approximately 19% of the world's population was undernourished — about 1 billion people out of 5.3 billion. By 2019, that share had fallen to 9.2% — while the world population had grown by 2.5 billion people. The undernourished share nearly halved even as billions more joined the population who needed to be fed.
Sub-Saharan Africa — the region most associated with persistent hunger — saw cereal yields increase by more than 50% since 1990 (FAO data). The continent still faces serious food security challenges. But the trend is in one direction: better yields, better storage, better trade logistics, better market access for smallholder farmers.
The mechanism behind these gains was not primarily foreign aid, though aid played a role in specific crises. The primary drivers were: improved crop varieties, fertilizer adoption, irrigation, reduction in post-harvest losses through better storage, and — critically — the expansion of trade that allowed regions with surplus to supply regions with deficit. A crop failure in one country no longer automatically produces famine when global food markets can reroute supply within weeks.
The Famine Researcher's Uncomfortable Conclusion
Alex de Waal is one of the world's leading scholars of famine — a researcher who has spent decades studying its causes and mechanisms. His conclusion, uncomfortable for those who prefer simpler narratives, is pointed:
"Famine is now almost entirely a political phenomenon — it happens where governments deliberately obstruct aid or starve populations. It no longer happens from crop failure alone."
North Korea. Yemen. Sudan. The Tigray region of Ethiopia. Every major famine in the 21st century has occurred where political actors — governments, militias, sanctions regimes — have deliberately or negligently blocked the food supply. The food exists. The global system can move it. What stops it reaching starving people is human politics, not agricultural limits.
This is progress framed in a grim light. The good news: nature alone can no longer starve us. The bad news: human beings can still choose to, and sometimes do. But the transformation from "famine as natural disaster" to "famine as political atrocity" is a profound shift. It means famine is no longer inevitable. It is always someone's choice.
