Famine is perceived as a problem of the past — something that happened in Ethiopia in the 1980s, in Ireland in the 1840s, or in China under Mao. The modern perception in high-income countries is that food production and distribution systems have solved the problem. They have not. Drought remains the deadliest category of climate-related disaster over the past half-century, and the trend since 2018 has reversed decades of progress. The WHO, WMO, and WFP all describe a global hunger crisis that is intensifying, not retreating.
Rough estimate: most people in high-income countries would place famine risk near zero for the world today — the actual ongoing toll is in the tens of thousands per year

Show derivation
The WMO Atlas of Mortality (1970–2019) recorded 650,000 drought-related deaths over 50 years, averaging 13,000 per year. This average is heavily influenced by catastrophic events in the 1970s-1980s (Ethiopia, Sudan, Mozambique). Modern-era annual drought mortality is lower but rising: the 2020s have seen renewed famine conditions in the Horn of Africa, Yemen, Sudan, and Gaza. Using the 50-year WMO average of 13,000/year as the central estimate: annual rate = 13,000 / 5,000,000,000 = 2.6 × 10⁻⁶. Compounded over 59 years: 1 − (1 − 2.6e-6)^59 ≈ 1.53 × 10⁻⁴, i.e. roughly 1 in 6,500. The uncertainty band uses a low of ~3,000 deaths/year (optimistic modern baseline, low: 3.54e-5) and a high of ~30,000/year reflecting years with acute crises (high: 3.54e-4).
Caveats: The 13,000 deaths/year figure is a 50-year average that masks enormous variation…
The 13,000 deaths/year figure is a 50-year average that masks enormous variation. The 1983 Ethiopian famine alone killed an estimated 400,000 people; several recent years have recorded fewer than 1,000 direct drought-attributed deaths. The modern-era toll depends heavily on whether ongoing crises (Horn of Africa 2022-2023, Sudan 2024, Gaza 2024) are classified as drought-driven or conflict-driven. Attribution is inherently difficult because drought kills indirectly — through crop failure, livestock death, water contamination, malnutrition- weakened immunity, and displacement — rather than through a single discrete event. The WHO lists malnutrition and an increased risk of infectious diseases (cholera, diarrhoea, pneumonia) among drought's health effects. For residents of high-income countries with diversified food supply chains, personal drought-famine risk is effectively zero under current conditions.
How the risk varies
The headline figure averages across very different situations. Here’s how the probability varies by scenario or context:
1 in 1,000
Historically the epicenter of drought-famine mortality. Ethiopia, Sudan, Somalia, and the Sahel belt account for the majority of global drought deaths. Recurrent crises in 2011, 2017, 2022-2023.
1 in 5,000
Large populations dependent on monsoon-fed agriculture; drought years trigger food crises, though famine-prevention systems have improved since the 1970s.
1 in 200,000,000
Diversified food supply chains, strategic grain reserves, and social safety nets make drought-famine deaths effectively unknown in the modern era.

Drought is the deadliest category of climate-related disaster. The World Meteorological Organization’s Atlas of Mortality, covering 1970 to 2019, attributes 650,000 deaths to drought over that half-century — an average of 13,000 per year and more than storms (577,000), floods (59,000), or extreme temperatures (56,000) over the same period. Over 91% of these deaths occurred in developing countries, with sub-Saharan Africa bearing the heaviest burden: drought accounted for 95% of all climate-related deaths on the continent. At the 50-year average rate, the global adult lifetime probability of dying from drought-induced famine is roughly 1 in 6,500.
The perception in high-income countries is that famine is a solved problem — a relic of pre-modern agriculture and colonial extraction. The data say otherwise. The 2020s have seen renewed famine conditions across the Horn of Africa, Yemen, Sudan, and Gaza, with the number of people facing catastrophic food insecurity (IPC Phase 5) more than doubling to 1.9 million in 2024 — the highest on record. The WHO notes that drought kills indirectly: it lists malnutrition from decreased food availability and an increased risk of infectious diseases — cholera, diarrhoea, pneumonia — among the acute and chronic health effects of drought. This indirect pathway makes attribution difficult and almost certainly leads to systematic undercounting in official disaster databases.
The 50-year average of 13,000 deaths/year smooths over extreme variation. The 1983 Ethiopian famine alone killed an estimated 400,000 people; several recent years have recorded fewer than 1,000 direct drought-attributed fatalities. But the trend since 2018 is upward, driven by conflict-drought intersections where war disrupts food distribution in already drought-stressed regions. Climate models project more frequent and severe droughts in the tropics and subtropics, suggesting that the long-term decline in famine mortality may have already reversed.
Related tidbits
Drought still kills an estimated 10,000 to 15,000 people a year worldwide, leaving a global adult about a 1 in 6,500 lifetime chance of a drought-attributable death. Most people in high-income countries place famine risk near zero for the modern world.

Droughts caused 650,000 deaths from 1970 to 2019, making them the deadliest category of climate-related disaster over this period; more than 91% of these deaths occurred in developing countries- Excerpt
“"Of the top 10 disasters, the hazards that led to the largest human losses during the period have been droughts (650 000 deaths). More than 91% of these deaths occurred in developing countries. Droughts led to the highest number of deaths [in Africa], accounting for 95% of all lives lost in the region." ”

- The WMO press release for the Atlas of Mortality and Economic Losses (1970–2019) reports 650,000 drought deaths over 50 years — an annual average of 13,000. Applied to a global adult population of 5 billion: annual rate 2.6e-6; compounded over 59 years: ~1.53e-4. The 50-year average smooths over extreme year-to-year variation (from near-zero in good years to 100,000+ during the 1983 Ethiopian famine).
