The Tuareg are a Berber ethnic group, found mostly in West Africa, but they were once nomads throughout the Sahara.
Today, however, nomads of all kinds are facing problems in preserving their cultural heritage.
The government of the Soviet Union tried to force the nomads to settle down, and most of them became assimilated.
Nomads, on the other hand, move periodically or cyclically, usually returning to their original location at various times.
