We are a nonprofit organization (501c3) wanting to advance the practice, and spread awareness of the opportunity, of turning atmospheric carbon into living landscapes and soil carbon (such as soil life, organic matter, humus, etc.). A different kind of science is needed, based on shared evidence, open participation, specific locations and situations, and on learning to manage wholes consisting of people, land, the work of all species, and money. Our principal project to date is the Soil Carbon Challenge, an international "competition" to see how fast land managers can turn atmospheric carbon into water-holding, fertility-enhancing soil carbon (the soil sponge). Peter has been touring the continent since 2011 in a converted school bus, doing soil sampling and monitoring on land managed by interested and committed people.

Building on the Challenge, we are facilitating community involvement in measuring and monitoring with the Atlas of Biological Work--an open-source platform or framework for facilitating shared, local intelligences on soil health and landscape function, based on wider participation and shared evidence. We're interested in collaboration with land-based organizations and districts. Peter is in process of rebuilding this into, which will have much more flexibility and can be configured on a per-project basis.

We think the opportunity for increasing carbon and water in the soil is huge, and will help drive improvement in social and economic conditions as well as enhance biodiversity and ecological resiliency. We also offer a participatory workshop as well as a residency for communities interested in organizing their own assets and resources toward this kind of shared intelligence.

After 22 years of clinical work with patients, she is now working with the Soil Carbon Coalition on a large-scale citizen-science program that engages schools, conservation districts, farmers, and the public in understanding the intersections between soil, water, public health, and climate resiliency. She develops curriculum on soil health principles and whole systems landscape function, and facilitates workshops that empower communities through mutual listening.

Cat Buxton of Sharon, Vermont is a consultant and teacher working to connect communities and empower individuals to affect positive food system change. Cat is an effective and enthusiastic presenter, community organizer, project manager, and an advocate for regenerative food systems and a healthy environment.
