The Soil Carbon Sponge: Structure, Function, and Formation: A Live Q&A with Walter Jehne

In this on-demand webinar with Soil Microbiologist and Climate Scientist Walter Jehne, and Land and Leadership Founder, Didi Pershouse (recorded live on June 12, 2019) we focus on, and answer questions about soil carbon and the soil carbon sponge--the natural infrastructure that underlies healthy functional landscapes and water cycles. Including:

  • Pedogenesis: the origins of the soil sponge.
  • What are the connections between soil carbon and water?
  • Mycorrhizzal fungi vs. Saprophytic fungi and their role in growing soil carbon.
  • How biology creates new water.
  • Soil degradation and oxidation of Carbon in soils.
  • How can we regenerate the soil carbon sponge?
  • Should human waste (urine and excrement) play a role in soil regeneration?

  • An investment in the development of new courses
  • A gesture of commitment towards the ongoing work of the teachers, and/or our overall Land and Leadership Initiative project.


Walter Jehne is an internationally recognized climate scientist, soil microbiologist, and innovation strategist. He has immense field and research experience in forests, grasslands, agriculture and soils at national (CSIRO) and international (UN) level. Walter has also worked more broadly at Federal Government level, leading transformation in the industry. This diversity of experience has given Walter an exceptional capacity to think in systems and see solutions - turning challenges into opportunities. Walter is well known for his ability to explain complex science in easy to understand ways.

Didi Pershouse

Didi Pershouse is the author of The Ecology of Care: Medicine, Agriculture, Money, and the Quiet Power of Human and Microbial Communities and Understanding Soil Health and Watershed Function. She is a lead author for the upcoming United Nations FAO Technical Manual on Soil Organic Carbon Management, and a contributing author to the upcoming volume Health in the Anthropocene.

As the founder of the Center for Sustainable Medicine, she developed a practice and theoretical framework for systems-based ecological medicine—restoring the health of people as well as the environmental and social systems around them. After 22 years of clinical work, Pershouse now travels widely in North America and Europe as a speaker and teacher. Her participatory workshops engage farmers and ranchers, policy makers, investors, and environmentalists in deep listening, systems thinking, and emergent strategies.

Both online and in-person, Pershouse is a skilled facilitator, who can bring together conservatives and liberals into effective working groups with common goals: improving soil health, public health, water security, and climate resilience through simple changes in land management.

She is the president of the non-profit Soil Carbon Coalition, Strategic Director of Regenerate Earth, and a co-founder of the "Can We Rehydrate California?" Initiative. She was one of five speakers at the United Nations-FAO World Soil Day in 2017. You can learn more about her work at www.didipershouse.com
