Turning the desert green

Available for over a year

The Sinai desert in Egypt is a dry, barren place where not much grows. But Ties van der Hoeven has come up with a scheme to turn it into a green and fertile land. It’s a plan on a huge scale which involves dredging a lake, restoring ecosystems, and even bringing back rain to the desert. He’s been inspired by a successful project to restore the Loess Plateau in China. But could it work in the Middle East? Produced and presented by Richard Kenny. Picture: Getty Images
