Trans-Saharan tradeTrans-Saharan trade requires travel across the Sahara between West, Central, Eastern and Northern Africa. While existing from prehistoric times, the peak of trade extended from the 8th century until the early 17th century. The Sahara once had a very different environment. In Libya and Algeria, from at least 7000 BC, there was pastoralism, the herding of sheep, goats, large settlements, and pottery. Cattle were introduced to the Central Sahara (Ahaggar) from 4000 to 3500 BC.
Toubou peopleThe Toubou or Tubu (from Old Tebu, meaning "rock people") are an ethnic group native to the Tibesti Mountains that inhabit the central Sahara in northern Chad, southern Libya and northeastern Niger. They live either as herders and nomads or as farmers near oases. Their society is clan-based, with each clan having certain oases, pastures and wells. The Toubou are generally divided into two closely related groups: the Teda (or Téda, Toda, Tireh) and the Dazagara (or Dazzaga, Dazagada, Daza).
African humid periodThe African humid period (AHP; also known by other names) is a climate period in Africa during the late Pleistocene and Holocene geologic epochs, when northern Africa was wetter than today. The covering of much of the Sahara desert by grasses, trees and lakes was caused by changes in the Earth’s axial tilt; changes in vegetation and dust in the Sahara which strengthened the African monsoon; and increased greenhouse gases. During the preceding Last Glacial Maximum, the Sahara contained extensive dune fields and was mostly uninhabited.
GaramantesThe Garamantes (Γαράμαντες; Garamantes) were an ancient civilisation based primarily in the southern region of Libya. They most likely descended from Toubou or Berber tribes and pastoralists from the Sahara. The Garamantes settled in the Fezzan region by at least 1000 BC,and by the late 7th century AD, the Garamantian civilization had ceased. The Garamantes emerged as a major regional power in the mid-2nd century AD and established a kingdom that spanned roughly in the Fezzan region of southern Libya.
Chad BasinThe Chad Basin is the largest endorheic basin in Africa, centered approximately on Lake Chad. It has no outlet to the sea and contains large areas of semi-arid desert and savanna. The drainage basin is approximately coterminous with the sedimentary basin of the same name, but extends further to the northeast and east. The basin spans eight modern nations, including most of Chad and a large part of Niger, Algeria, Libya, Sudan, Nigeria, Cameroon, Central African Republic.
AwjilaAwjila (Berber: Awilan, Awjila, Awgila; أوجلة; Latin: Augila) is an oasis town in the Al Wahat District in the Cyrenaica region of northeastern Libya. Since classical times it has been known as a place where high quality dates are farmed. From the Arab conquest in the 7th century, Islam has played an important role in the community. The oasis is located on the east-west caravan route between Egypt and Tripoli, Libya, and on the north-south route between Benghazi and the Sahel between Lake Chad and Darfur, and in the past was an important trading center.
TénéréThe Ténéré (Tuareg: Tenere, literally: "desert") is a desert region in south central Sahara. It comprises a vast plain of sand stretching from northeastern Niger into western Chad, occupying an area of over . The Ténéré's boundaries are said to be the Aïr Mountains in the west, the Hoggar Mountains in the north, the Djado Plateau in the northeast, the Tibesti Mountains in the east, and the basin of Lake Chad in the south. The central part of the desert, the Erg du Bilma, is centred at approximately .
Libyan DesertThe Libyan Desert (not to be confused with the Libyan Sahara) is a geographical region filling the northeastern Sahara Desert, from eastern Libya to the Western Desert of Egypt and far northwestern Sudan. On medieval maps, its use predates today's Sahara, and parts of the Libyan Desert include the Sahara's most arid and least populated regions; this is chiefly what sets the Libyan Desert apart from the greater Sahara.
FezzanFezzan (UKfɛˈzɑːn , USfɛˈzæn,_fəˈzæn ; Fezzan; Fizzān; Phazania) is the southwestern region of modern Libya. It is largely desert, but broken by mountains, uplands, and dry river valleys (wadis) in the north, where oases enable ancient towns and villages to survive deep in the otherwise inhospitable Sahara Desert. The term originally applied to the land beyond the coastal strip of Africa proconsularis, including the Nafusa and extending west of modern Libya over Ouargla and Illizi.
Lake ChadLake Chad (Kanuri: Sádǝ, Lac Tchad) is a freshwater lake located at the junction of Nigeria, Niger, Chad and Cameroon in central and western Africa. It is also an important wetland ecosystem in West Africa. The catchment area of Lake Chad is 1 million square kilometers. It used to be a large lake with an area of 28,000 square kilometers in the 19th century. However, due to climate change and human water diversion, Lake Chad has been greatly reduced since the mid-1970s, and its area has fluctuated between 2,000 and 5,000 square kilometers.
