Planning for Tourism, Leisure and Sustainability: International Case Studies by Anthony S. Travis
The Sahara has mesmerized outsiders for centuries. The world's largest desert, its size defies imagination: 3.3 million square miles or around 25 percent of Africa. Not surprisingly, the Sahara's name in Arabic means simply "desert."
For nearly 500,000 years, the Sahara has attracted people from throughout North Africa. Early residents came when the Sahara was lush and teeming with wildlife.
As the region became desert, the Sahara's residents turned to livestock herding. And, to trade caravans that brought gold, ivory, salt and slaves north, and commercial goods and metals south.
Now, with just 2.5 people per square mile, the region's residents can seem afloat in a sea of sand. Among them are Arabs, Berbers, Bedouins, Fulani, Nubians and Tuareg.
The Tuareg, a semi-nomadic group known for their salt caravans and distinctive blue veils, are the region's best-known people.
