Wildest Africa (2010 - 2010)

Namibia's Namib desert is the result of Atlantic winds eroding ancient mountains. Extremely hot and arid, it requires elaborate adaptations from wildlife and rare tribal populations.

The Okavango Delta, in northern Botswana, comprises various wetlands, some (river arms and marshes) deep enough for hippopotamuses to live in, many drying out many months, some barely seasonal waterholes. Many species (like buffalo) and people migrate in and out on the flood rhythm, while only the Bushmen survive all year in the neighboring Kalahari desert.

For 2000 miles, the mighty Zambezi flows from the Zambian highlands trough Angola, Botwsana and Zimbabwe to Mocambique, to end in the Indian Ocean. Its immense water volume has a massive impact on wildlife in its huge flood areas and trough erosion reshapes its own bed, most spectacularly at the Victoria falls, the world's greatest waterfall.
