What is the primary source of food in the Sahara?

The primary source of food in the Sahara Desert is derived from subsistence farming and livestock herding, particularly among nomadic groups. Crops such as millet, dates, and sorghum are cultivated in oases and along riverbanks where water is available. Additionally, trade plays a significant role, as communities exchange goods and food with neighboring regions. Overall, the harsh environment limits agricultural production, making food sources highly dependent on available water and climate conditions.
