Operation Okavango travels to Niger and Chad, two countries among a dozen others, to share the world's largest desert: the Sahara. An Arab saying asserts that the Sahara is the garden of Allah. The God of the Righteous would have taken away all human life there in order to have a space in which to walk in peace. yet men have adapted to this immensity of sand and rocks. They exploited the oases, traced caravan trails, founded cities in the middle of the sands. Departing from Bilma on the oldest trans-Saharan track that connects the Mediterranean to Lake Chad, the members of Okavango formed 3 teams to meet the nomadic peoples of Aïr and Tibesti.
