WATER
Water is the main factor. If sufficient water is available, people can live and farm in an area of desert.

water for people who live in the desert
Very few people live in the desert because people require water and the desert has very little water. People also need food and without water, the desert can not grow crops. As a result, the only places where people live in desert regions are areas with abundant water. Examples include the Nile Valley of Egypt where the Nile river runs through the desert, Iraq between the Tigris and Euphrates rivers, Pakistan near the Indus River, and Souther California with the diverted water from the Colorado River. They do not live in the middle of the Sahara.
If people have the proper clothing, shelter, tools, food and water they can live indefinitely in the desert. I have lived more than 40 years in the Chihuahuan Desert.
