Life on the plains and grasslands of the world is about movement, freedom and livestock. The Nyangatom of southern Ethiopia have fought and won a rangeland for themselves, but they and their herds of cattle and goats are totally reliant on gigantic wells. At the height of the dry season a huge collective well is dug down on the dry bed of the Kibish River. These hand dug wells can be 30m wide and 30m deep and are designed as pits as the sand walls are prone to collapse. Dozens of people are killed by collapsing wells each year.
