Owen Hablutzel will be making several guest appearances in my upcoming podcasts. He is part of Geoff Lawton's PRI USA team. Plus a certified Holistic Management educator (Alan Savory's stuff) and keyline guy.
This is a picture of a project that went from a huge expanse of cracked clay desert, to a field of weeds with doing nothing more than running a keyline plow on it. There is also a video of Owen giving a presentation at the international permaculture convergence in Jordan.
