I watched this video, as well at the Allan Savory TED talk about greening the desert (see
http://www.youtube.com/watch?v=vpTHi7O66pI if you haven't seen it). In his talk, Allan Savory (who emphasizes introducing herds and moving them around) dismisses the approach that Liu recommends (planting native species). They both have beautiful before and after pics but I was sort of curious if anyone else had seen the two and can square them.
