The Sahara desert if the largest desert in the world: it covers approximately 9 million square km, about 207,000 of which are covered with oases. In the past, up to 3000-4000 years ago, the Sahara desert had a more humid climate and its soil was more suitable for sheep-breeding and farming (millet used to be grown there as early as 8000 years ago); then, as it slowly dried up and with desertification, the people who lived there moved to the oases, where farming is possible with the support of special irrigation techniques.
