This evolution is altering the traditional lifestyles and economic activities of indigenous groups such as the Tuaregs.- Statement 1 is Correct: The Sahara is witnessing rapid infrastructural changes. Superhighways are being constructed across the desert, often superseding the ancient camel paths that were historically used for trade caravans.
