A meta-analysis of projected global food demand and population at risk of hunger for the period 2010–2050

🤖 Plain-English Summary

Quantified global scenarios and projections are used to assess long-term future global food security under a range of socio-economic and climate change scenarios. Across 57 global food security projection and quantitative scenario studies that have been published in the past two decades, the total global food demand is expected to rise from +35% to +56% between 2010 and 2050, and the population at risk of hunger is expected to change by −91% to +8%.

🔑 Key Findings

• Here, we conducted a systematic literature review and meta-analysis to assess the range of future global food security projections to 2050.
• We reviewed 57 global food security projection and quantitative scenario studies that have been published in the past two decades and discussed the methods, underlying drivers, indicators and projections.
• Across five representative scenarios that span divergent but plausible socio-economic futures, the total global food demand is expected to increase by 35% to 56% between 2010 and 2050, while population at risk of hunger is expected to change by −91% to +8% over the same period.
