Allan Savory: How to fight desertification and reverse climate change

Allan Savory's solution to the problem of desertification runs completely counter to my intuition and everything I've been taught about why desertification happens in the first place, but his solution seems to be proven to work.

From TED:

“Desertification is a fancy word for land that is turning to desert,” begins Allan Savory in this quietly powerful talk. And 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.
