Oasis
In ecology, an oasis (; ) is a fertile area of a desert or semi-desert environment'ksar''with its surrounding feeding source, the palm grove, within a relational and circulatory nomadic system.” The location of oases has been of critical importance for trade and transportation routes in desert areas; caravans must travel via oases so that supplies of water and food can be replenished. Thus, political or military control of an oasis has in many cases meant control of trade on a particular route. For example, the oases of Awjila, Ghadames and Kufra, situated in modern-day Libya, have at various times been vital to both north–south and east–west Trans-Saharan trade, trade in the Sahara Desert. The location of oases also informed the Darb El Arba'īn trade route from Sudan to Egypt, as well as the caravan route from the Niger River to Tangier, Morocco. The Silk Road “traced its course from water hole to water hole, relying on oasis communities such as Turpan in China and Sam ...

Foggaras
A qanat or kārīz is a system for transporting water from an aquifer or water well to the surface, through an underground aqueduct; the system originated approximately 3,000 BC in what is now Iran. The function is essentially the same across North Africa and the Middle East but the system operates under a variety of regional names: ''qanat'' or kārīz in Iran, ''foggara'' in Algeria, ''khettara'' in Morocco, ''falaj'' in Oman, ''karez'' in Afghanistan, ''auyoun'' in Saudi Arabia, et al. The largest extant and functional qanat systems are located in Iran, Afghanistan, Oman, the oases of Turfan region of China, Algeria, and Pakistan. This is a system of water supply that allows water to be transported over long distances in hot dry climates without loss of much of the water to evaporation. The system has the advantage of being resistant to natural disasters such as earthquakes and floods, and to deliberate destruction in war. Furthermore, it is almost insensitive to the level ...

Al-Ahsa Oasis
''Al-Aḥsāʾ'' ( ar, الْأَحْسَاء, ''al-ʾAhsā''), also known as al-Ḥasāʾ () or Hajar (), is a traditional oasis historical region in eastern Saudi Arabia whose name is used by the Al-Ahsa Governorate, which makes up much of that country's Eastern Province. The oasis is located about inland from the coast of the Persian Gulf. Al-Ahsa Oasis composed four main cities and 22 villages. Two of these four main cities are Al-Mubarraz and Al-Hofuf, which are two of the 15 largest cities in Saudi Arabia. With an area of around , Al-Ahsa Oasis is the largest oasis in the world.

Kufra
Kufra () is a basinBertarelli (1929), p. 514. and oasis group in the Kufra District of southeastern Cyrenaica in Libya. At the end of nineteenth century Kufra became the centre and holy place of the Senussi order. It also played a minor role in the Western Desert Campaign of World War II. It is located in a particularly isolated area, not only because it is in the middle of the Sahara Desert but also because it is surrounded on three sides by depressions which make it dominate the passage in east-west land traffic across the desert. For the colonial Italians, it was also important as a station on the north-south air route to Italian East Africa. These factors, along with Kufra's dominance of the southeastern Cyrenaica region of Libya, highlight the strategic importance of the oasis and why it was a point of conflict during World War II. Etymology The folk etymology associaters the word Kufra as coming from the Arabic word kafir, the Arabic term for non-Muslims (often transla ...

Turpan
Turpan (also known as Turfan or Tulufan, , ug, تۇرپان) is a prefecture-level city located in the east of the autonomous region of Xinjiang, China. It has an area of and a population of 632,000 (2015). Geonyms The original name of the city is unknown.

Desert
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid. This includes much of the polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting fragments and rubble strewn over the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arabian Peninsula
The Arabian Peninsula, (; ar, شِبْهُ الْجَزِيرَةِ الْعَرَبِيَّة, , "Arabian Peninsula" or , , "Island of the Arabs") or Arabia, is a peninsula of Western Asia, situated northeast of Africa on the Arabian Plate.

Trans-Saharan Trade
Trans-Saharan trade requires travel across the Sahara between sub-Saharan Africa and North 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. Remarkable rock paintings (dated 3500 to 2500 BC) in places that are currently very dry, portray flora and fauna that are not present in the modern desert environment. As a desert, Sahara is now a hostile expanse that separates the Mediterranean economy from the economy of the Niger basin. As Fernand Braudel points out, crossing such a zone, especially without mechanized transport, is worthwhile only when exceptional circumstances cause the expected gain to outweigh the cost and the danger. Trade was conducted by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
