Food systems transformation would reshape global agriculture.

Transforming global food systems toward healthy diets by 2050 could reduce agricultural land use by 6% and lower overall agricultural production value by 26%, reshaping agriculture fundamentally.

• Why it matters: Addressing the environmental and health impacts of current food systems is critical as population and income growth threaten to worsen planetary boundaries and diet-related mortality risks, yet the potential scale of agricultural change remains underexplored.
• What they did: Using a multimodel ensemble of ten global economic models, the study simulates scenarios where adopting the EAT-Lancet diet, improving productivity, and halving food waste lead to significant shifts in agricultural land, production, and economic value by 2050.
• The result: The findings suggest a substantial decline in livestock production and a rise in vegetable, fruit, nut, and legume outputs, emphasizing the importance of proactive food policies to realize health and environmental benefits.
