As shepherd nomads, they move with their herds through the endless expanses of the Sahara. Only rarely do they encounter oases. Their settlement area extends over Chad, Niger and Libya with the center in the Tibesti Mountains. Therefore, they are also called «people of the mountains». The increasing land demand of the surrounding states restrict their freedom of movement more and more. They have adapted to this extreme habitat, as well as their most important livestock, the camel. All of the belongings fit on a few animals and when they move, only the wooden structure of their mat tents remains. Cooking is done on a wood fire and if there is no wood to be found, camel dung is used. With the help of camels, they also laboriously bring up the water from wells that are several tens of meters deep.
