Didi Pershouse

Founder and Lead Educator for LALI;  Coordinator, Researcher and Writer for Seed Media Project

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 "Future Directions" chapter of the UN-FAO Technical Manual on Soil Organic Carbon Management, and a contributing author for 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—to restore health to people as well as the environmental and social systems around them.  After 22 years of clinical work with patients, Pershouse now travels widely in North America and Europe as a speaker, teacher, and consultant.

Pershouse is a skilled facilitator, who brings conservatives and liberals together into effective working groups with common goals: improving soil health, public health, food and water security, and regional resilience through simple changes in land management. Both online and in-person, her participatory workshops engage farmers and ranchers, policy makers, investors, and scientists in living-systems thinking and deep listening, to allow for emergent strategies. She was one of five speakers at the United Nations-FAO World Soil Day in 2017.

Walter Jehne

Scientific Advisor, Educator, and Writer for Seed Media Project

Walter Jehne is an internationally known Australian soil microbiologist and climate scientist. After many years as a researcher, he is now a sought after speaker and consultant for land restoration projects, policy work, and investment projects. He is well-known for his strategic vision that we can safely cool regions, and potentially even the global climate, by repairing our disrupted hydrological cycles. His work centers around practical strategies including restoring the structure and function of “the soil sponge” in order to reverse desertification, increase nutritional integrity of crops, and provide resilience to drought, flooding, heat waves, and wildfires. 

Jehne was a pioneer researcher on soil carbon, glomalin, mycorrhizal fungi and plant root zone ecology.  As a research scientist at CSIRO (Australia’s scientific research organization), Jehne investigated the potential of mycorrhizal fungi to recolonize toxic, degraded soils and rebuild productive biosystems. Later he worked with the Australian national government  to foster strategic innovation by changing the paradigm of land management.

Thorsten Arnold 

Scientific Advisor, Writer and Researcher for Seed Media Project

Thorsten has dedicated his work life to promoting climate resilience in its various facets. With his wife Kristine Hammel, he co-owns Persephone Market Garden, an ecological vegetable farm that produces healthy, fair and simply good food. They are slowly building this into a community hub, having integrated a summer farm camp, farming workshops, and now a private farm & forest school that offers holistic education in sustainable living. He offers workshops on planning for Climate Resilience on farms, and as a speaker who raises awareness on the soil sponge and the biosphere’s ability to self regulate the climate.

Thorsten has a PhD in watershed sciences and agricultural economics from the University of Hohenheim, Germany; a Master’s degree in Marine Environmental Science from the Institute for Chemistry and Biology of the Sea at the University of Oldenburg, Germany; and an undergraduate degree in environmental and process engineering (BTU Cottbus). His academic training uniquely bridges various aspects of climate dynamics: global greenhouse gas forcing, oceans, and the role of regional land use and agriculture.
