Diet, Land Use, and the Biofuel Nexus
Most analyses of land availability for biomass crops has focused on abandoned land, which had been increasing for many years in the U.S. until the advent of corn ethanol demand. In this study we unpack the role of diet, both existing trends and nutritional recommendations, on land requirements for food production. Results suggest a potentially large reduction in food-land requirements for the U.S. that could translate into a large biofuel supply. While our analysis was confined to the U.S. food system, several trends suggest increasing availability of agricultural land around the globe as well. Will we use reclaim this land for biodiversity and nature, abandon it as wasteland, or develop sustainable strategies for agro-biofuel landscapes that also provide valuable ecosystem services? These are important choices our society should begin considering now.
