Sahara
built 279 days ago
Historically, the Sahara was a large barrier to aspiring conquerors - Egyptians, Romans, Carthaginians, and Arabs. Islam spread steadily... in part from the activities of Muslim traders and scholars. Explorers from Britain and France began to penetrate the Sahara in the early part of the nineteenth century. French conquests began in 1830. Political boundaries in the Sahara were defined only in the late nineteenth and the twentieth centuries. Much was left imprecise by the French, who ruled over most of the region, resulting in a number of border disputes after decolonization, including those between Morocco and Algeria over the Tindouf area, and Libya and Chad with regard to the Aozou strip.

The Sahara is known to have one of the harshest climates in the world. The prevailing north-easterly wind can often cause the sand to form sand storms and dust devils.[18] Precipitation, while rare is not unknown. Half of the Sahara receives less than 2 cm of rain a year, with the rest receiving up to 10 cm a year.[19] The rainfall happens very rarely, but when it does it is usually torrential when it occurs after long dry periods, which can last for years.

Two thirds of the Sahara's estimated 2 million inhabitants (excluding those in the Nile valley) are concentrated in oases where date palms, fruits, vegetables, grains, and other crops are produced under irrigation. Nomads, with herds of sheep and goats and with camels for transportation, predominate in drier areas and continue to use oases (including modern oases created by the drilling of wells), as in centuries past, for water, trade, and provisioning stops. The principal ethnic groups of the Sahara are the Tuareg (of Berber origin), who dominate the mountains of the central Sahara; the peoples of mixed Berber and Arab origin in W Sahara; and the Tibu (Tébu), who dominate the Tibesti Massif.

South Saharan steppe and woodlands: The South Saharan steppe and woodlands occupy a narrow band running east and west between the hyper-arid Sahara and the Sahel savannas to the south. Movements of the equatorial Intertropical Convergence Zone (ITCZ) bring summer rains during July and August which average 100 to 200 mm, but vary greatly from year to year. These rains sustain summer pastures of grasses and herbs, with dry woodlands and shrublands along seasonal watercourses. The ecoregion covers 1,101,700 square kilometers (425,400 square miles) in Algeria, Chad, Mali, Mauritania, and Sudan.[23]
