Over the last four episodes, we’ve heard how we need to change our food system to one that is nature-positive. But how can we scale a circular economy for food to feed the global population, which the UN estimate will reach 10 billion by 2057?

In the final episode of our Redesigning Food series, we hear from Professor Tim Benton, Research Director of the Environment and Society Programme at Chatham House, the Royal Institute of International Affairs, and Mikel Hancock, Walmart’s Senior Director for Sustainability Initiatives, about the role policymakers and big businesses can play.

This episode was supported by players of People’s Postcode Lottery.
