This series of maps comes from National Geographic’s “A Five-Step Plan to Feed the World.” The maps detail in what ways we can be more efficient about where we grow, what we grow, and how we grow.
We can no longer afford to increase food production through agricultural expansion. Nearly all new food production in the next 25 years will have to come from existing agricultural land.
Only 55 percent of food-crop calories directly nourish people. Meat, dairy, and eggs from animals raised on feed supply another 4 percent. It would be easier to feed the planet if more of the crops we grew ended up in human stomachs.
Improving nutrient and water supplies where yields are lowest could result in a 58 percent increase in global food production.
