Town living is sometimes fleeting and seasonal. Cyclical migration is developing between the bush and the town, either at the regional level (Faya, Agadez, Kidal, Atar, Ouarzazate, Tamanghasset, Sebha, etc.) The economic diversification of nomadism is therefore ushering in small-scale urban trades, such as retail commerce, animal guarding, and to a lesser degree, tourism" and crafts.
