Cattle were introduced to the Central Sahara between 4000 and 3500 BCE. Remarkable rock paintings (dated 3500 to 2500 BCE) in arid regions portray flora ...
Climate scientists used models to show historic intervals of a green, vegetated Sahara Desert that occur every 21,000 years. The Sahara Desert—Yes, That One—Remarkably Grows Green Every 21,000 ...
Researchers in the Sahara Desert are using the same technique to remove salt from saltwater to irrigate plants by using cool ground water to evaporate warm sea water, which is then condensed in a ...
