Windhoek and Leonardville, Namibia – Impo Gift Kapamba Musasa holds a hose pipe in one hand and gestures to a garden of cabbages, onions and turnips with the other. He is a teacher in the crumbling village of Leonardville in rural Namibia, where water is becoming scarce.
The vegetables, grown for children at the primary school where he teaches, are watered from one of the largest aquifers on earth. The groundwater nourishes tens of thousands of people and is the lifeblood of the Kalahari Desert, which stretches across Namibia, as well as neighbouring Botswana and South Africa.
