The Saharan Region is a vast desert region located in North Africa. It is bordered by the Mediterranean Sea to the north, the Atlantic Ocean to the west, and the Red Sea to the east. The region is divided into two distinct areas: the Sahel and the ERG. The Sahel is a semi-arid region that stretches from the Atlantic Ocean to the Red Sea, while the ERG is an area of sand dunes and rocky plateaus. Both regions are characterized by extreme temperatures and lack of rainfall.
