- Over 295 million people experienced hunger and starvation globally in 2025 due to conflict, displacement, climate change, and economic disasters.
- Climate change is predicted to lead more than a billion people into food crises by 2100, if high levels of greenhouse gas emissions continue.
- Africa is expected to be disproportionately affected by climate change, with over 170 million people facing food crises in 2099 alone.
- Transitioning to sustainable development and reducing fossil fuel burning could halve the number of people experiencing food crises by 2100, according to the AI model.
- The impact of climate change on food insecurity will hit younger populations the hardest by 2100. Around 600 million children may experience a severe food crisis before the age of five.
- If policy choices shift towards sustainability, over 780 million people could be spared from food crises by 2100.
- Urgent global actions are needed to steer development toward mitigation and sustainability to ensure food security for future generations.
