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.

Following their session together at this year’s Oxford Real Farming Conference – Land, Food and Spirit – SFT CEO, Patrick Holden, and renowned biologist and author, Rupert Sheldrake, reconnected to record an episode of the SFT Podcast. Rupert’s impressive career started at Cambridge University where he studied Natural Sciences, before receiving a scholarship to attend Harvard University, studying History and Philosophy of Science. Rupert later returned to Cambridge where he gained a PhD in Plant Development. This eventually led him to India, where he worked at The International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), to develop a more holistic approach to biology and science: “the mechanistic, materialist paradigm was too limiting and constricting” resulting in the idea of ‘morphic resonance’. Rupert has also authored more than 100 technical papers and nine books, including Science and Spiritual Practices. This episode takes a slightly different turn from our usual episodes, with less focus on agriculture, and more on the role of spirituality in science. During this episode, Patrick and Rupert discuss bridging the gap between spirituality and science, they ask whether farms could be considered ‘holy places’, Rupert explains his theory of morphic resonance and talks about his involvement with the British Pilgrimage Trust.

For this episode of the SFT podcast, Max Jones – transhumance guide and traditional foods archivist – visits our CEO, Patrick Holden, on Patrick’s farm in Wales.  Alongside his work as a transhumance guide – the practice of moving livestock from one grazing ground to another in accordance with the seasons – Max Jones is also a writer, photographer, educator and founder of Up There The Last, a project which aims to reconnect people with their food and educate them about the traditional food practices of the past, which still exist in some parts of the world today. From rare cheese production in the heights of the Alps, to traditional wild salmon smoking in the republic of Ireland, Max Jones’ journey to seek out and learn more about traditional food practices has taken him all over the world and led him to meet the people working hard to preserve these essential practices that are at risk of being left behind and forgotten. In this episode, Max and Patrick talk about the threat to traditional foods including modern technology and health and safety regulations, as well as the presence of an off-the-record 'food counterculture' that exists to protect ancient practices. To find out more about Max, follow him on Instagram, and visit the Up There The Last website and Substack page. You can also read the article that Max wrote for the SFT about the importance of preserving traditional food practices, here: https://sustainablefoodtrust.org/news-views/preserving-the-practices-of-traditional-foods/.

To coincide with the release of our new report, Grazing Livestock: It's not the cow but the how, the latest guest on the SFT Podcast this month is Nic Renison. Nic is a regenerative farmer based in Cumbria where she farms alongside her husband, Paul (Reno), at Cannerheugh Farm. The daughter of dairy farmers, Nic grew up within the conventional, high production agricultural environment, growing food with little thought of the environment. This all changed in 2012 when Nic and Reno had a 'light bulb' moment after visiting an organic farm in Northumberland, which inspired them to start employing more regenerative farming methods. In 2018, alongside Liz Genever, Nic co-founded Carbon Calling – a conference created for farmers, by farmers, to share ideas and exchange knowledge on all things farming and regenerative agriculture. During the episode Nic and Patrick discuss Nic's early farming influences, her and her husband's journey from conventional to regenerative farming methods and the origins of the Carbon Calling conference, and how it supports the wider farming community. To find out more about Nic and Cannerheugh Farm, follow their journey on Instagram and visit their website here.

Kicking off series five of the Sustainable Food Trust podcast, Patrick Holden, SFT CEO and organic dairy farmer, catches up with Dani Nierenberg, President of Food Tank. Dani Nierenberg is a world-renowned researcher, speaker, and advocate, on all issues relating to our food system and agriculture. In 2013, Dani co-founded Food Tank with Bernard Pollack, a nonprofit organisation focused on building a global community for safe, healthy, nourished eaters. Food Tank is a global convener, thought leadership organisation, and unbiased creator of original research impacting the food system. Dani has an M.S. in Agriculture, Food, and Environment from the Tufts University Friedman School of Nutrition Science and Policy and spent two years volunteering for the Peace Corps in the Dominican Republic. In this first episode of the new series, Dani and Patrick discuss the impact of an extractive approach to agriculture upon our planet and our health. They consider how we can switch to a more regenerative approach – one that restores the soil, conserves water, and reduces the need for agrichemicals. Dani shares her insights on the recent shake-up in US politics and what the new administration could mean for food and farming, as well as exploring challenges relating to certification, labelling and consumer engagement. The conversation also examines the true cost of industrial food production, which typically isn’t reflected in the retail price, and unpicks some of the sustainable agriculture challenges currently being faced in California and beyond. Commenting on what gives her hope for the future, Dani gives plenty of reasons to be optimistic, including opportunities for young people in agriculture and the huge potential for collaboration within the food and farming sector.

Bringing the fourth series of the SFT podcast to a close, Patrick Holden caught up with longtime friend and one of the pioneers of the UK’s organic farming movement, Iain ‘Tolly’ Tolhurst. “We need to bring farming back into society. It’s become completely divorced from society.” Tolhurst Organic, located on the Hardwick Estate between the Chilterns and the river Thames, is a model of sustainability, and one of the longest running organic vegetable farms in England. For over 40 years, Tolly has been producing a wide range of seasonal, organic fruits and vegetables, which are sold to the local community through a box scheme. His farm was the first to attain the “Stockfree Organic” symbol in 2004, and there have been no grazing animals and no animal inputs to any part of the farm for over 30 years. To build soil fertility, Iain uses green manures as part of a crop rotation, as well as using vegetable and woodchip compost from waste materials. With his extensive knowledge and experience of organic food production, Iain also delivers educational talks across the UK and beyond, and runs a consultancy service giving advice on organic conversion and production, helping to train and educate farmers and growers for the future. During this episode, Patrick and Tolly explore the economics of farming and what it means to pay the ‘right price’ for our food. Tolly also talks about the productive capacity of Tolhurst Organic and how they’re feeding the surrounding community through their veg box scheme. Patrick and Iain delve into the current state of the UK farming sector amidst the changing policy around farm subsidies and how this is affecting both organic and conventional farmers, before closing with a conversation on the importance of demonstration farms for informing and educating people about the story behind their food and the need to incentivise farmers for this.
