Is it possible to feed almost ten billion people by 2050, while keeping within planetary boundaries?
According to the most comprehensive study of food systems to date, the answer is: yes. But not without major changes in how we produce and consume food.
The EAT-Lancet Commission’s report identifies food systems as “the single biggest cause of planetary boundary transgressions”, and the main driver of biodiversity loss and emissions (30% of the global total).
But it doesn’t have to be this way. In its report, it said that an urgent reduction in meat and dairy consumption, particularly in the west, could put diets on a more sustainable footing. It also advocates for an increase in the production and consumption of whole grains, fruit, nuts and vegetables.
According to the commission, its ‘planetary health diet’ offers a template for a “science-backed dietary pattern” that promotes human health and protects the planet. Mass adoption of this, it estimates, could deliver returns of $5tn (£3.74tn) a year through better health, restored ecosystems, and climate resilience.
“Transforming food systems is not only possible, it’s essential to securing a safe, just, and sustainable future for all,” said Johan Rockström, the commission’s co-chair.
