Molly Biddell on rewilding at Knepp estate and measuring social impacts

After both appearing on the Grazing for Good: Livestock and Biodiversity in the UK panel at ORFC earlier this year, SFT CEO, Patrick Holden, sat down once again with Molly Biddell, Head of Natural Capital at Knepp Estate – a 3,500-acre rewilding project in West Sussex – for an episode of the SFT Podcast.

Her work involves leveraging nature markets and policy for Knepp, Weald to Waves and the River Adur Landscape Recovery project. She also works part-time at Hampton Estate, a family-run regenerative farming business, facilitates the Upper Adur Farming Cluster group and is a columnist for Farmers Weekly.

In this episode, Patrick and Molly talk about the work going on at Knepp Estate – 'a radical rewilding experiment', says Molly – including the success they've had so far in terms of an increase in biodiversity, carbon sequestration and habitat restoration. They also talk about the role of projects like Knepp Estate to improve public awareness of rewilding and more sustainable agricultural methods, before finishing the episode with a discussion on measuring the climate, nature and social impacts of such projects.
