A recent study found that global croplands produce enough calories to feed twice the world's population, but only half of those calories are consumed as food, highlighting the impact of policy and priorities on land use. Researchers suggest producing food on existing farmland while protecting and restoring nature to balance nourishment with planetary health. Shifting excess beef consumption to chicken or plant-based proteins could free up enough calories to feed millions of people, while improving how cropland is allocated can help meet nutritional needs without expanding into natural ecosystems. Targeted shifts in commodity production and country policies could significantly increase food availability from existing croplands, offering a clear opportunity to address climate change, biodiversity loss, and food insecurity.
