Seth Itzkan kindly provided some video of the short talks at this event at Stan and Helen Ward's Three Springs Farm in Waitsfield, Vermont on October 21, 2011.

Peter Donovan and Abe Collins are co-founders of the Soil Carbon Coalition, which initiated the Challenge.

Seth Itzkan is a futurist from the Boston area who recently spent 6 weeks at the Africa Centre for Holistic Management in Dibangombe, Zimbabwe.

This is an excellent presentation by Jay Fuhrer, who works for the Natural Resource Conservation Service in North Dakota, USA. He uses case studies to explain how innovative use of cover crops can boost soil health and productivity, and dramatically reduce the use of artificial fertilizers.

The Burleigh County Soil Conservation District website is a gold mine of inspiration and innovation for farmers of all stripes.

Part 2

Soil scientist Ray Archuleta shows a remarkable contrast in the responses of tilled and no-tilled soil to water. Note that the biological glue he speaks of during the second half, substances such as glomalin, are one of the important large compounds that contain soil carbon. The takeaway from this demonstration is also that soil organic carbon has huge leverage on the effectiveness of the water cycle. See also http://managingwholes.com/eco-water-cycle.htm

This is perhaps one of the oldest known films on the Keyline concept filmed on PA Yeomans' former farm 'Nevallan' circa 1955. Its somewhat remarkable from a few perspectives:
* It was produced by a Bank
* It was made at a time when fertiliser technology in agriculture was promising subsidised fertility out of a bag as opposed to conscious design and management of the natural elements
* It is 55 years on and we still have landscapes that rapidly shed water, soils that are eroding, rural communities shrinking, cities not feeding and watering themselves etc. etc. etc.

Allan Yeomans, author of Priority One: Together We Can Beat Global Warming has a series of videos on climate change and soil. Here are Parts 1 and 2.

Filmmaker John Liu has documented the World Bank's $500 million loess plateau watershed rehabilitation project since it began in 1995. He has made at least two compelling films about the project, including a 22-minute version was shown at the recent Copenhagen climate conference, and a more detailed 52-minute version.
