Deserts are arid regions with little vegetation that are characterized by extreme temperatures. The Sahara desert is the largest hot desert found in North Africa, covering over 8 million square kilometers across 11 countries. Temperatures in the Sahara can exceed 50°C during the day. Nomadic tribes such as the Bedouins and Tuaregs inhabit the Sahara and rely on livestock like camels for their livelihood. Ladakh is a high altitude cold desert in India with harsh winter conditions where people engage in farming during summer and festivals to pass winter months.
