Tuat
Tuat, or Touat, is a natural region of desert in central Algeria that contains a string of small oases. In the past, the oases were important for caravans crossing the Sahara. Geography Tuat lies to the south of the Grand Erg Occidental, to the east of the Erg Chech and to the south west of the Tademaït Plateau. It contains a string of small oases strung out along the eastern edge of the Wadi Messaoud, a continuation of the Wadi Saoura. The oases extend over a distance of 160 km from the district of Bouda in the north to Reggane in the south. The largest town in the region is Adrar, 20 km south east of Bouda. Adrar was established by the French after their conquest in 1900 and had a population of 43,903 in 2002. Associated with each oasis are small walled villages called '' ksour'' (singular ''ksar'' or ''gsar''). There are also some forts (''kasbahs''), most of which have been abandoned. There is almost no rainfall in the region and the agriculture depends on grou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tademaït
Tademaït is a natural region in the Sahara Desert right in the centre of Algeria. It is located north of In Salah and south of the Grand Erg Occidental in the Adrar District of Adrar Province, El Ménia District of Ghardaïa Province and the northern end of Tamanrasset Province. It is one of the places of the Sahara Desert where the summer heat is most extreme. Geography The Tademaït is a rocky plateau made up of cretaceous terrain with a general slope towards the northeast.

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 ...

Moscovian (Carboniferous)
The Moscovian is in the International Commission on Stratigraphy, ICS geologic timescale a stage (stratigraphy), stage or age (geology), age in the Pennsylvanian (geology), Pennsylvanian, the youngest system (stratigraphy), subsystem of the Carboniferous. The Moscovian age lasted from to Megaannum, Ma, is preceded by the Bashkirian and is followed by the Kasimovian. The Moscovian overlaps with the European regional Westphalian (stage), Westphalian stage and the North American Atokan and Desmoinesian stages. Name and definition The Moscovian Stage was introduced by Sergei Nikitin (geologist), Sergei Nikitin (1850 - 1909) in 1890, using brachiopods in the Moscow Basin of European Russia. Nikitin named the stage after Moscow, then a major city and now the capital of Russia. The base of the Moscovian is close to the first appearances of the conodonts ''Declinognathodus donetzianus'' and ''Idiognathoides postsulcatus'' or otherwise the fusulinid ''Aljutovella aljutovica''.

Cenomanian
The Cenomanian is, in the ICS' geological timescale, the oldest or earliest age of the Late Cretaceous Epoch or the lowest stage of the Upper Cretaceous Series. An age is a unit of geochronology; it is a unit of time; the stage is a unit in the stratigraphic column deposited during the corresponding age. Both age and stage bear the same name. As a unit of geologic time measure, the Cenomanian Age spans the time between 100.5 and 93.9 million years ago (Mya). In the geologic timescale, it is preceded by the Albian and is followed by the Turonian. The Upper Cenomanian starts around at 95 Mya. The Cenomanian is coeval with the Woodbinian of the regional timescale of the Gulf of Mexico and the early part of the Eaglefordian of the regional timescale of the East Coast of the United States. At the end of the Cenomanian, an anoxic event took place, called the Cenomanian-Turonian boundary event or the "Bonarelli event", that is associated with a minor extinction event for marine spec ...

Phoenix Dactylifera
''Phoenix dactylifera'', commonly known as date or date palm, is a flowering plant species in the palm family, Arecaceae, cultivated for its edible sweet fruit called dates. The species is widely cultivated across northern Africa, the Middle East, and South Asia, and is naturalized in many tropical and subtropical regions worldwide. ''P. dactylifera'' is the type species of genus ''Phoenix (plant), Phoenix'', which contains 12–19 species of wild date palms. Date trees reach up to in height, growing singly or forming a clump with several stems from a single root system. Slow-growing, they can reach over 100 years of age when maintained properly. Date fruits (dates) are oval-cylindrical, long, and about in diameter, with colour ranging from dark brown to bright red or yellow, depending on variety. Containing 61–68 percent sugar by mass when dried, dates are very sweet and are enjoyed as desserts on their own or within confectionery, confections. Dates have been cultiv ...

Foggara
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 leve ...

Center Pivot Irrigation
Center-pivot irrigation (sometimes called central pivot irrigation), also called water-wheel and circle irrigation, is a method of crop irrigation in which equipment rotates around a pivot and crops are watered with sprinklers. A circular area centered on the pivot is irrigated, often creating a circular pattern in crops when viewed from above (sometimes referred to as ''crop circles'', not to be confused with those formed by circular flattening of a section of a crop in a field). Most center pivots were initially water-powered, however today most are propelled by electric motors. Center-pivot irrigation systems are beneficial due to their ability to efficiently use water and optimize a farm's yield. The systems are highly effective on large land fields. History Center-pivot irrigation was invented in 1940 by the farmer Frank Zybach, who lived in Strasburg, Colorado. It is recognized as an effective method to improve water distribution to fields. In 1952, Zybach went into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
