Dorn Cox is a New Hampshire family farmer who has long been in the vanguard of improving regenerative agriculture with open source technologies. He sees participatory science and knowledge commons as powerful tools for improving crop yields, soil health, and ecosystem resilience, especially in the face of climate change. Here, Cox talks about his new book 'The Great Regeneration' on these themes, and the encouraging vistas of possibility that open source hardware, data analytics, knowledge-sharing and localism are opening up.
