The paper reviewed 57 studies: total food demand rises 35–56% from 2010 to 2050 across five SSPs (+30% to +62% with climate change), and population at risk of hunger changes by −91% to +8% (−91% to +30% with climate change), "with no statistical differences overall." - Affiliations as listed on the paper: Wageningen Economic Research (the Hague) and the International Institute for Applied Systems Analysis (Laxenburg). - Data and code are public on Zenodo ([database](https://doi.org/10.5281/zenodo.4911252), [code](https://doi.org/10.5281/zenodo.4911251)). - Lomborg uses the paper's Fig. 3d (SSP2, +50.7% vs +48.7% total calories) to argue climate change is "a problem, not a catastrophe"; see the [[Authors/@BjornLomborg/Post Analyses/Post Analysis - BjornLomborg on Climate Change and 11 Percent More Calories by 2050 (2024-08-01)|Aug 1, 2024 calories analysis]]. - See also [[Topics/Climate Change Science and Policy Debate/People/Bjørn Lomborg|Bjørn Lomborg]].
