Meeting growing demands for food calories will be a substantial challenge. One place to search for solutions is in how we allocate the
world’s crops, and finding ways to feed more people with current crop production. Currently, a substantial proportion of crop calories are
used as animal feed, and only a small fraction of those feed calories ultimately contribute to human diets. Countries like the United States and China, which together produce over a third of the world’s meat, eggs and dairy, lose a substantial portion of calories and protein to the feed-to-animal conversion process.
This study looks at global croplands that have a large difference between calories grown, and the food calories available for consumption. These hotspots have the potential to feed more people, while reducing envi-ronmental impacts of agriculture
