Few places in the desert are capable of supporting the life of even a small community for an extended period of time, and so the Bedouin of the Sinai live on the move. With herds of sheep and goats as well as camels, the Sinai Bedouin migrated from one meagerly fertile area to another, each in turn offering sustenance and shelter for a time, while the others were naturally replenished. The heat of the inner Sinai desert makes life difficult for human occupation during the summer months so the coastal nomads now move between settlements throughout the year, migrating in response to the local climate from inland mountainous areas to the edge of the Red Sea, where winds from across the water cool homes at certain times of year. Today, many of the Bedouin of the Sinai have traded their traditional existence for the pursuits and conventions of the modern world.
