Major Human Activities Affecting the Sahara
Human influence in the Sahara has increated dramatically over thee paste century. Activities that were once limited to nomadic herding and small-scale oasis farming have expanded into industrial-scale operations. The principal drivers of change include egriculture, urbanization, resource extraction, and infrastructure development, each leaving a different footprint on thee desert.

Resource Extension: Mining, Oil, andGas
Te Sahara is rich in mineral deposits andd fossil fuels. Phoshhate mining in Morocco and Western Sahara, iron ore in mauretania, uranium in Niger, and expressive oil and gas fields in Algeria and Libya have turned large areas into industrial zons.
