More than 1 in 9 people were experiencing hunger in 2021, even as 3.1 billion people could not afford a healthy diet, a gap that turns price pressure into food insecurity. At the same time, food affordability is being squeezed from every direction, from fertilizer costs and cereal price stress to conflict driven displacement and micronutrient deficits. This post brings those forces together using the latest global benchmarks on sanitation, nutrition, and humanitarian need so you can see where severity is rising and why.
Key Takeaways
- In 2022, 29% of the global population did not have access to basic sanitation services, worsening health environment and nutrient absorption among vulnerable households.
- In 2023, the FAO Cereal Price Index averaged 120.2, indicating ongoing cereal cost pressure globally.
- In 2023, global food losses and waste were estimated at 1.05 billion tonnes per year, which increases scarcity and cost pressures that contribute to food insecurity.
- In 2022, fertilizer prices were on average about 3–4 times higher than pre-2021 levels, reducing input affordability for farmers and worsening food insecurity risks.
- In 2022, the Global Agriculture and Food Security Program (GAFSP) reported that climate shocks were a key driver of food insecurity, with significant impacts on yields for vulnerable producers.
- Globally, women face higher risk of food insecurity due to gender inequalities: FAO and partners report persistent gender gaps in access to resources that contribute to hunger.
- In 2023, acute malnutrition among children was reported with widespread prevalence in high-burden countries; UNICEF documented that 47.0 million children under 5 were affected by wasting (acute malnutrition).
- In 2023, UNICEF estimated 148.1 million children under 5 were stunted (low height-for-age), reflecting chronic undernutrition linked to food insecurity.
- In 2023, 21.9 million people were in IPC Phase 5 (famine) conditions or higher, indicating the most severe food insecurity outcomes.
- In 2022, the IMF estimated food and energy inflation added about 2.7 percentage points to global inflation, affecting food affordability and informing policy responses.
- In 2023, OECD-DAC donors committed $35.0 billion in gross ODA for agriculture, forestry, fishing and crop-based food systems, supporting food security programming.
- In 2022, 24.2% of adults in low- and lower-middle-income countries reported worrying about running out of food at least sometimes (Gallup World Poll, used in the State of Food Security and Nutrition in the World).
- 3.1 billion people were unable to afford a healthy diet in 2021, representing about half of the world’s population, per the Global Food Security Index and related affordability analysis.
- In 2023, global food retail sales were roughly $8.6 trillion (industry market estimate), reflecting the scale of affordability and price transmission channels.
- 59 million people in 2023 were in IPC Phase 4 (Emergency) or above, indicating extreme short-term food insecurity severity.
Rising prices, conflict, and climate shocks are driving extreme hunger and malnutrition for millions worldwide.

Agricultural Inputs2 stats
01
In 2021, about 37 million farms were operating in Sub-Saharan Africa (farm counts used in FAO-style compilations published by the World Bank Data Lab).
02
In 2022, 10–15% of fertilizer used globally is estimated to be wasted or not efficiently utilized, reducing yields and contributing to affordability pressure (peer-reviewed nutrient use efficiency literature).
Interpretation
Agricultural Inputs Interpretation
For the Agricultural Inputs side of food insecurity, the scale is striking with about 37 million farms in Sub Saharan Africa in 2021, and in 2022 an estimated 10 to 15 percent of globally used fertilizer was wasted or not efficiently utilized, meaning less usable inputs are likely translating into lower yields and higher affordability pressure.
