The Iran War's Other Casualty: The Global Food Supply.

← all posts

The media coverage of the Iran war has focused almost entirely on oil, gas prices, and military operations. Those things matter. But there's a slower, larger catastrophe building in the background that has gotten almost no attention in US political coverage: the global fertilizer supply is being strangled, sub-Saharan Africa is entering its spring planting season unable to source the inputs farmers need, and the World Food Programme is warning that 45 million additional people could be pushed into acute food insecurity by mid-year if the war continues. Before this war started, 318 million people across 68 countries were already experiencing acute food insecurity. This conflict is now threatening to add another 45 million to that number.

Why Fertilizer Is the Hidden Crisis.

Fertilizer — specifically nitrogen fertilizers like urea and ammonia — is the foundation of modern food production. Without it, crop yields collapse. Iran, Qatar, Saudi Arabia, and Oman are among the world's leading exporters of nitrogen fertilizers. They also export the raw ingredients — natural gas and minerals — that other countries use to manufacture their own. The Strait of Hormuz was handling roughly a third of all global fertilizer trade before the war. Now it is at what the UN World Food Programme calls "a virtual standstill." Unlike oil, there is no internationally coordinated strategic reserve for nitrogen fertilizer, according to the UN Food and Agriculture Organization. When oil is disrupted, countries can tap reserves. When fertilizer is disrupted, farmers simply don't have it — and there's no backup. Fertilizer plants in India, Bangladesh and Pakistan have already had to stop production entirely as natural gas and oil prices have spiked, according to experts cited by NPR.

Sub-Saharan Africa Is Walking Into a Planting Season Without Fertilizer.

The timing couldn't be worse. Sub-Saharan Africa is entering its spring planting season right now. Farmers who already had their crop yields squeezed by extreme weather are now facing fertilizer they can't get or can't afford. The WFP's head of food security analysis, Jean-Martin Bauer, described it directly: under normal circumstances, WFP purchases food in India, ships it to Salalah, then to Jeddah, and into Port Sudan. Because of the war, those shipments are being rerouted on a path 9,000 kilometers longer — equivalent to crossing the United States coast to coast and back again — adding roughly 25 days to shipping times. WFP's shipping costs are already up 18%. That means less food for the same money, or the same food for more money WFP doesn't have. The agency has already been forced to cut food rations for people in famine conditions in Sudan. It is currently only able to support one in four acutely malnourished children in Afghanistan — already the world's worst malnutrition crisis.

This Is Worse Than the Russia-Ukraine Disruption in 2022.

The WFP explicitly compares this to the Russia-Ukraine fertilizer and food crisis of 2022 — which triggered a cost-of-living emergency that pushed 349 million people into hunger. The key difference: in 2022, countries could find alternative fertilizer sources by increasing imports from the Middle East. The Middle East was the backup. Now the Middle East is the crisis. The Council on Foreign Relations called it "a threat to the world at large" if left unaddressed, warning that the fertilizer shock combined with climate-stressed growing seasons, depleted grain reserves, and debt-constrained governments has "the potential to convert a regional military conflict into a global humanitarian crisis." Food price inflation in Iran itself has risen 40% in the past year. Prices for rice have increased sevenfold. The people closest to the war are already starving.

The Countries That Can't Absorb Another Shock.

Before this war, famine conditions already existed at IPC Phase 5 — the highest level of food catastrophe — in Sudan, Gaza, Yemen, and South Sudan. These countries are almost entirely import-dependent on food, fuel, and fertilizer. Any disruption in supply chains has immediate, severe consequences. In Afghanistan, the war is adding to multiple overlapping crises including conflict with Pakistan and two major earthquakes in 2025. Afghans currently in Iran face the prospect of being forced to return home, where food access is already critically strained. The WFP warned that even small increases in food costs push already-vulnerable families into crisis — and that's before accounting for the ripple effect of lower harvests in 2026 if this planting season fails across sub-Saharan Africa.
