Impacts of land use, population and climate change on global food security

The research evaluates future food security using the FEEDME model, incorporating IPCC climate scenarios and Shared Socio-economic Pathways. The findings suggest that while climate change affects crop yields, population growth is the primary driver of undernourishment prevalence, with rapid population growth correlating with the worst food security outcomes.

• Population growth is identified as the primary driver of changes in undernourishment prevalence, exerting a larger impact on future food insecurity than climate change scenarios, despite the latter's effect on crop yields.
• There is a direct correlation between population growth rates and food security levels, where countries with rapid growth experience the most severe impacts and those with decreasing growth show higher security.
• To prevent severe future food insecurity, the paper recommends strategies to mitigate population growth impacts, such as improving maternal health care, increasing national food access equality, closing the yield gap, and altering trade patterns.
