About Allan Savory's TEDTalk
About two-thirds of the world's grasslands have turned into desert. Allan Savory has devoted his life to stopping it. He now believes that a surprising factor can protect grasslands and even reclaim degraded land that was once desert.
About Allan Savory
Allan Savory works to promote holistic management in the grasslands of the world. In the 1960s, while working in Africa on the interrelated problems of increasing poverty and disappearing wildlife, Savory made a significant breakthrough in understanding the degradation and desertification of grassland ecosystems.
In 1992, Savory and his wife, Jody Butterfield, formed the Africa Centre for Holistic Management in Zimbabwe, a learning site for people all over Africa. In 2010, the Centre won the Buckminster Fuller Challenge for its work in reversing desertification. In that same year he and his wife, with others, founded the Savory Institute in Boulder, Colo., to promote large-scale restoration of the world's grasslands.
