Allan Savory, How to fight desertification

“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.

I used this in class with page 117, SpeakOut Intermediate, Unit 10 - as a supportive exercise of reported speech. The students listened and then had to tell me what they felt were the key points of what he discussed.

I have also used this with IELTS, as a follow up activity to Unit 1 IELTS reading skills, where the topic and vocabulary are the same.  Please also find a wordle with vocaubulary here:
