‘Eating organic’ requires farming differently. Organic agriculture manages crop varieties and rotations to manage pests and nutrients. This study analyses different scenarios of organic conversion, finding that a smaller area worldwide planted with wheat, rice and maize must be offset by more nitrogen-fixing crops, such as beans, alfalfa and clover. Even then, caloric energy would fall by about 27% from current production.
