Summary
Hall et al. applied the FEEDME modelling framework to project food security outcomes across 44 African countries to 2050, accounting for population growth and climate change scenarios. The analysis reveals that rapid population growth is the dominant driver of projected food insecurity and undernourishment, with climate change contributing minimal additional effect. The authors discuss adaptation strategies including yield gap closure through sustainable intensification and trade/aid agreements as potential mitigation approaches.
UK applicability
This study focuses on African food security and has limited direct applicability to UK agricultural or nutritional contexts. However, the findings underscore global food system interdependencies and the importance of yield improvements and trade arrangements, which may inform UK food policy and international development priorities.
Key measures
Undernourishment prevalence; food availability; impacts under different climate scenarios (IPCC SRES projections); population growth projections
Outcomes reported
The study modelled the impacts of future climate change and population growth on food availability and undernourishment prevalence across 44 African countries by 2050 using the FEEDME modelling framework. Projections indicate that population growth will be the dominant driver of food insecurity, with climate change effects showing minimal additional impact on undernourishment.
