Allan Savory: How to green the world's deserts and reverse climate change | Video on TED.com »
“Desertification is a fancy word for land that is turning to desert,” begins Allan Savory in this quietly powerful talk. And terrifyingly, it's happening to about two-thirds of the world’s grasslands, accelerating climate change and causing traditional grazing societies to descend into social chaos. Savory has devoted his life to stopping it. He now believes -- and his work so far shows -- that a surprising factor can protect grasslands and even reclaim degraded land that was once desert.
