Global Famine
The Hunger Games, minus the archery.
What it is
Global famine means food production or distribution failing across several regions at once, leaving hundreds of millions of people without enough to eat. Modern agriculture depends on fertilizer, diesel, stable weather and open trade routes. If several of those fail together, local shortages can turn into a global crisis.
Why it ranks where it does
Several stresses are hitting at once right now. Diesel and fertilizer prices have soared because of the Iran war, just as a strong El Niño threatens harvests. The WHO is also circulating a food-insecurity and malnutrition alert for Sudan. Famine is also the main way that nuclear war would kill most of its victims, so it's linked closely to the scenarios above it.

What the experts say
Researchers who model global food shocks stress that the world produces enough calories today and that most famines are caused by conflict and policy, not absolute shortage. A true global famine would need a major shock such as nuclear winter, simultaneous breadbasket failures or a collapse of trade. That keeps it below the top tier but well above the Hollywood scenarios.
What would move the number
Up
- Failed harvests in several major exporting regions
- Fertilizer and fuel shortages lasting into the 2027 planting season
- Grain-export bans
Down
- Reopened shipping through the Strait of Hormuz
- A mild El Niño
- Humanitarian access in Sudan and other conflict zones
