A new study published in Nature today found that combining healthier diets, sustainable agricultural intensification, and cutting food waste in half would reduce pressure on land and natural resources while still meeting food needs. * Combined with sustainable agricultural intensification, this means that global agricultural land use could decline by 6-42% compared to a business-as-usual scenario by 2050. Using analysis from an ensemble of ten different global economic models from collaborating partners around the world, researchers compared a business-as-usual scenario to 2050 with a scenario that combines three major changes: adoption of healthier diets based on the 2025 EAT-Lancet recommendations, sustainable agricultural intensification, and a 50% reduction in food loss and waste.
