Every year ten trillion litres of water cascade down from the Angolan highlands into the Okavango River and then spread out across the landscape, creating the largest inland delta in the world (seen to fabulous effect in stunning satellite shots). But what stops the water from simply draining away or becoming stagnant and turning the Okavango Delta into a saline lake? Narrator Steve Backshall has the answer, and it’s quite a surprise.

Once again, this series packs a lot of information into its short running time, not to mention wonderful photography: highlights include catfish gulping for air as waterholes dry up and elephants gambolling underwater.


Steve Backshall turns his attention to Africa, exploring Botswana's Okavango Delta, one of the world's largest inland deltas which is home to a wide and diverse spectrum of wildlife. He asks what makes it possible for a river to stop in the middle of a desert and reveals an astonishing secret.
