“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.
