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.

Lecture to the Royal Society in October 2007 by James Lovelock. "Climate change on a living earth," 65 minutes. Lovelock eloquently depicts the fragmentation of scientific understanding, which makes us unable to grasp global heating or to counter it. "In our hubris, we believe that we can be stewards of the earth long before we understand it."

"Perhaps the saddest thing is that if we fail, Gaia will lose as much or more than we do. Not only will wildlife and whole ecosystems go extinct, but in human civilization the planet has a precious resource. We are not merely a disease; we are through our intelligence and communication the planetary equivalent of a nervous system. We should be the heart and mind of the Earth, not its malady. Perhaps the greatest value of the Gaia concept lies in its metaphor of a living Earth, which reminds us that we are part of it and that our contract with Gaia is not about human rights alone, but includes human obligations."
