Redefining Soil Health: Systems Thinking and the Future of Soil Science

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.Read more about Dan and Jim's research on soil health in 'A New Theory for Soil Health' from the European Journal of Soil Science.To learn more about the European Journal of Soil Science and how to submit a paper, click here For more information, visit: soils.org.uk/soilmatters
