Episode 6 – Old Knowledge – Indigenous Wisdom for Sustainable Land Management
Description
In this special two part edition of Soil Matters, host Paul Lincoln explores how centuries of Indigenous knowledge are shaping modern approaches to soil health and sustainable land management across Africa.
In part 1, joined by three inspiring guests—Divine Ntiokam (Global Climate Smart Agriculture Youth Network), Jemimah Kutata (Maasai disability rights advocate and community leader), and Dr Awdenegest Moges (Hawassa University, Ethiopia)—the conversation spans youth-led climate-smart agriculture, grassroots empowerment, and community driven soil restoration.
Together, they reveal how traditional practices complement modern soil science, strengthen resilience against desertification and drought, and connect local stewardship to global agendas on food security and climate justice. From Kenya’s Indigenous governance of land resources to Ethiopia’s Rift Valley restoration projects, this episode highlights the vital role of indigenous communities in safeguarding the future of our soils.
Subscribe now to hear how “old knowledge” offers fresh solutions for today’s soil challenges and why listening to Indigenous voices is key to building climate resilience worldwide.

Episode 1 – Bioremediation
Description
Tackling land contamination and how soil made it to a central London art gallery
Professor Frederic Coulon, Professor Tony Gutierrez, and Professor Jack Hannam
In previous years, land contamination was seen as an impediment to making the most of a site. Groundbreaking new approaches to bioremediation have completely changed the approaches to reclaiming land and to realising its true worth. Speaking on behalf of the EBNet project, soil scientists Professor Fred Coulon and Professor Tony Gutierrez, outline their current research and their plans for the future.
At the heart of their work is the potential for using bioremediation for carbon capture, a topic that is also address in a new art exhibition at London’s Somerset House. British Society of Soil Science Past-President, Professor Jack Hannam, visited in the opening week and explains why this landmark exhibition offers an amazing opportunity to connecting the public to a scientific body of research and elevate the importance of soil science in tackling climate change and food security.

Episode 2 – Regenerative Agriculture
Description
In this episode of Soil Matters, host Paul Lincoln explores the practical and philosophical dimensions of regenerative agriculture with Professor Anna Krzywoszynska, Professor Lynn Dicks, and PhD researcher Raquel Falcão. Together, they unpack recent research published in Soil Use and Management, delving into how farmers understand and apply sustainable soil practices, the risks of greenwashing in regenerative claims, and the crucial role of collaboration between farmers, scientists, and policymakers. From soil lifespans to farmer-led innovation, this conversation challenges assumptions and highlights the urgent need for holistic, context-specific support in soil stewardship.
Regenerative agriculture is an approach to farming that focuses on restoring and enhancing the health of the soil, enhancing ecosystems and also supporting the communities that sustain them. The practice emphasizes the regeneration of topsoil, increasing biodiversity, improving the water cycle and strengthening the health and vitality of farm soil. Key principles include minimal soil disturbance, diversifying crop rotations and integrating livestock by prioritizing soil health. Regenerative agriculture aims to create resilient farming systems that can adapt to climate change, improve food security and support sustainable agricultural practices.
The episode is inspired by two articles published recently in the Soil Use and Management journal (SUM). The first is called Sustainable soil management in the United Kingdom: A survey of current practices and how they relate to the principles of regenerative agriculture. The second is called Farmers’ perception of soil health: The use of quality data and its implication for farm management.

Episode 3 – Soil Health
Description
In this episode of Soil Matters, we explore the evolving concept of soil health and its far-reaching implications for science, technology, communication, and practice.
Soil Matters host, Paul Lincoln, is joined by Professor Jim Harris, Dr. Daniel Evans from Cranfield University, and Dan Lambeth, Trustee of the British Society of Soil Science, to explore the evolving concept of soil health and its far-reaching implications for science, technology, communication, and practice. Marking the 75th anniversary of the European Journal of Soil Science and its special call for papers, the panel discusses the origins and challenges of defining soil health—a concept that has inspired policymakers and land managers but continues to spark debate among scientists.
Jim Harris and Dan Evans reflect on their personal journeys in soil science and the discipline’s shift from viewing soil as a static material to understanding it as a dynamic, complex system. They highlight how the accessibility of the term “soil health” makes it a powerful tool for engagement, while also cautioning against oversimplification. The conversation underscores the need for dynamic, systems-based approaches to measurement that capture the true complexity, resilience, and emergent properties of healthy soils.
Dan Lambeth offers his perspective on bridging soil science, policy, communication, and sustainable investment, drawing on his experience in finance and sustainability reporting. He discusses the increasing interest in soil health from the private sector, the importance of robust data for investment, and the need for a shared language among scientists, policymakers, and land managers.
The episode also features Professor Jenni Dungait, Editor in Chief of the European Journal of Soil Science, who shares her vision for the journal’s future as it enters an exciting new chapter.

Description
In this special on-location episode of Soil Matters, host Paul Lincoln and the British Society of Soil Science with the Ecological Continuity Trust (ECT) visits Colt Park Meadows an experiment supported by ECT, situated within the heart of the Yorkshire Dales to explore one of the UK’s longest-running ecological experiments.
Joined by Professor Richard Bardgett (Lancaster University) and Ben Sykes (ECT), the episode delves into the vital role of funding for long-term ecological field experiments in understanding soil health, biodiversity, and resilience to climate extremes. Together, they unpack over three decades of data, from red clover’s surprising impact on carbon sequestration to the value of “do nothing” control plots. The conversation highlights how slow, subtle changes in soil and vegetation can carry powerful lessons for land managers, policymakers, and scientists alike.
Discover why long-term perspective matters, how research informs real-world practice, and how a humble meadow is helping shape the future of sustainable land use.
