Prince William and the Defra Secretary say regen agriculture is the future.

Charlotte Smith visits Groundswell, the regenerative agriculture festival in Hertfordshire, where the focus is on improving the soil and reducing artificial fertilisers and pesticides. She speaks to the so-called grandfather of regen, Gabe Brown, and the Green Farm Collective's Tim Parton about greenwashing and the future.

Presented by Caz Graham and produced by Beatrice Fenton.
