Ribiana Sand Sea
The Rabyanah Sand Sea, Rabyanah, is a sand desert region in the southeastern sector of Libya with a surface of approximately 65,000 km2. Geography The area of the Rabyanah Sand Sea is in the western part of the Libyan Desert in the Kufra District of the Cyrenaica region. It is named after the oasis town of Rabyanah located towards its eastern end. Together with the Calanshio Sand Sea and the Great Sand Sea, the Rabyanah Sand Sea is part of the greater Libyan Desert.Besler, Helga (2008).

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 ...

Libyan Desert
The Libyan Desert (not to be confused with the Libyan Sahara) is a geographical region filling the north-eastern 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. The consequent absence of grazing, and near absence of waterholes or wells needed to sustain camel caravans, prevented Trans-Saharan trade between Kharga (the Darb al Arbein) close to the Nile, and Murzuk in the Libyan Fezzan. This obscurity saw the region overlooked by early European explorers, and it was not until the early 20th century and the advent of the motor car before the Libyan Desert started to be fully explored. Nomenclature The term 'Libyan Desert' began to appear widely on European maps in the last decades of the 19th century, typically identified ...

Erg (landform)
An erg (also sand sea or dune sea, or sand sheet if it lacks dunes) is a broad, flat area of desert covered with wind-swept sand with little or no vegetative cover. The word is derived from the Arabic word ''ʿarq'' (), meaning "dune field". Strictly speaking, an erg is defined as a desert area that contains more than of aeolian or wind-blown sand and where sand covers more than 20% of the surface. Smaller areas are known as "dune fields". The largest hot desert in the world, the Sahara, covers and contains several ergs, such as the Chech Erg and the Issaouane Erg in Algeria. Approximately 85% of all the Earth's mobile sand is found in ergs that are greater than . Ergs are also found on other celestial bodies, such as Venus, Mars, and Saturn's moon Titan. Description Ergs are concentrated in two broad belts between 20° to 40°N and 20° to 40°S latitudes, which include regions crossed by the dry, subsiding air of the trade winds. Active ergs are limited to regions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Libya
Libya (; ar, ليبيا, Lībiyā), officially the State of Libya ( ar, دولة ليبيا, Dawlat Lībiyā), is a country in the Maghreb region in North Africa. It is bordered by the Mediterranean Sea to the north, Egypt to Egypt–Libya border, the east, Sudan to Libya–Sudan border, the southeast, Chad to Chad–Libya border, the south, Niger to Libya–Niger border, the southwest, Algeria to Algeria–Libya border, the west, and Tunisia to Libya–Tunisia border, the northwest. Libya is made of three historical regions: Tripolitania, Fezzan, and Cyrenaica. With an area of almost 700,000 square miles (1.8 million km2), it is the fourth-largest country in Africa and the Arab world, and the List of countries and outlying territories by total area, 16th-largest in the world. Libya has the List of countries by proven oil reserves, 10th-largest proven oil reserves in the world.

Kufra District
Kufra or Kofra ( ar, الكفرة '), also spelled ''Cufra'' in Italian, is the largest district of Libya. Its capital is Al Jawf, one of the oases in Kufra basin. There is a very large oil refinery near the capital. In the late 15th century, Leo Africanus reported an oasis in the land of the ''Berdoa'', visited by a caravan coming from Awjila. It is possible that this oasis was identical with either the Al Jawf or the Taiserbo oasis, and on early modern maps, the Al Kufra region was often labelled as ''Berdoa'' based on this report. History The name ''Kufra'' (comes from Kufuh and Epher) itself is a derivation from ''kafir'', the Arabic term for non-Muslims. Kufra did not fall under the dominion of either the Arabs or the Ottomans and was owned by the Arab Bedouin tribe of the Zuwayya only in the mid 19th century, and eventually by the Italians by the 1930s. In 1931, during the campaign of Cyrenaica, General Rodolfo Graziani easily conquered Kufra, considered a strategic re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyrenaica
Cyrenaica ( ) or Kyrenaika ( ar, برقة, Barqah, grc-koi, Κυρηναϊκή παρχίαKurēnaïkḗ parkhíā}, after the city of Cyrene), is the eastern region of Libya. Cyrenaica includes all of the eastern part of Libya between longitudes E16 and E25, including the Kufra District. The coastal region, also known as '' Pentapolis'' ("Five Cities") in antiquity, was part of the Roman province of Crete and Cyrenaica, later divided into ''Libya Pentapolis'' and ''Libya Sicca''. During the Islamic period, the area came to be known as ''Barqa'', after the city of Barca. Cyrenaica became an Italian colony in 1911. After the 1934 formation of Libya, the Cyrenaica province was designated as one of the three primary provinces of the country. During World War II, it fell under British military and civil administration from 1943 until 1951, and finally in the Kingdom of Libya from 1951 until 1963. The region that used to be Cyrenaica officially until 1963 has formed seve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Rebiana, Libya
Rebiana (or ''Rabiana'', ''Rabyanah'', also called ''Erbehna'', ar, موزي or ), in Tedaga called or Saad Abdulla Buhagar: ''L'Art rupestre du Sud-Est libyen (Région de Kufra)'' , Benghazi, 2014, , p. 7. which is the original name of this place, is an oasis in the Libyan Desert in the Kufra District of Libya, about 120 km west of El Tag. On one side of the oasis, which features many palm and mango trees, is a salt lake and a chain of hills; on the other are sand dunes. On the north edge of the oasis there is a village with a zaouia. The native inhabitants are members of the Toubou people; Al Tawatia and Bazama peoples have also settled there. In 2014, the Libyan historian Saad Buhagar described the population of Rebiana as follows: "After some migration towards the big cities, for reasons of employment and comfort, between 1500 and 2000 individuals remain, most of them Tubu, and a small group of Zouia Arabs, most of them of the Bazama family, descendants of the Elmdjabra ...

Great Sand Sea
The Great Sand Sea is an approximately sand desert (erg) in the Sahara between western Egypt and eastern Libya in North Africa. Some 74% of the area is covered by sand dunes. Geography The Great Sand Sea stretches about from north to south and from east to west. On satellite images this desert shows a pattern of long sand ridges running in a roughly north-south direction. However, despite the apparent uniformity the Great Sand Sea has two large areas with different types of megadunes.Besler, Helga (2008) ''The Great Sand Sea in Egypt: Formation, Dynamics and Environmental Change: A Sediment-Analytical Approach'' Elsevier, Amsterdampage 1 - 3 The Egyptian sand sea lies parallel to the Calanshio Sand Sea of Libya, with which it is contiguous in the north. The dunes of the Great Sand Sea cover about 10 % of the total area of the Egyptian Western Desert.

Deserts Of Libya
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] |
