Can Sludge From Dams Turn Deserts Into Farmland?
Afforest for the Future is one of a series of projects trying to create arable land from sand. It’s method: use the muck that collects behind dams to create new soil.
Al Qudra Lake, a reservoir in Dubai, sits in the middle of the desert. But in September, a stretch of sand near the lake will become a nearly instant garden. A pilot project will test a new process for turning desert into arable land.
