nomadic:
In the northern and southern limits of the desert there are some tribes engaged in raising sheep: they are the khebbache ait of southern Morocco, the Ouled Zekri arba'as and southern Algeria, the Tunisian South merazigues. The lamb is adapted without difficulty to the prairies of salt plants; also supports the cold winter of Hamada, have provided good food, but in summer, you must drink regularly every two days. Therefore, it can only survive if it spends the summer in the vicinity of the wells, where soon consume all the grass, or in a constant back and forth between the desert and some wet region. Regular migration, called on Algeria Achaba, leading, for, example, herds of arba'as from the region of dayas in southern Lagwat where overwinter until the settled area of Sersu, where they remain thus establishes during the summer. Other tribes, who have the possibility to spend the dry season out of the desert, devoted exclusively to camel breeding; such is the case of Algeria regueibat (Lguacem) or Mauritania (Sahel). In winter there is the problem of trough and summer just visit the wells from time to time. The herd can then be dispersed in search of verdant sites and maximize the field; the inhabitants of the stores are exempt from the concern of water, replacing with camel milk. Economically perfect simple system that allows nomadic almost total freedom of movement. For centuries camel caravans represented one of the core activities of the nomads. Passengers and goods circulated in groups, under the supervision remunerated tribes whose territories crossed. At the time that the closed economy was usual in Europe, caravans West Africa introduced an economy with free competition. (Robert Capot-Rey)
