DuneA dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes with little or no vegetation are called ergs or sand seas. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter slip face in the lee side.
CyrenaicaCyrenaica (ˌsaɪrəˈneɪɪkə,_ˌsɪr- ) or Kyrenaika (Barqah, Kurēnaïkḗ [eparkhíā], after the city of Cyrene), is the eastern region of Libya. Cyrenaica includes all of the eastern part of Libya between the 16th and 25th meridians east, 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.
ChadChad (tʃæd ), officially the Republic of Chad, is a landlocked country at the crossroads of North and Central Africa. It is bordered by Libya to the north, Sudan to the east, the Central African Republic to the south, Cameroon to the southwest, Nigeria to the southwest (at Lake Chad), and Niger to the west. Chad has a population of 16 million, of which 1.6 million live in the capital and largest city of N'Djamena. Chad has several regions: a desert zone in the north, an arid Sahelian belt in the centre and a more fertile Sudanian Savanna zone in the south.
CamelA camel (from camelus and κάμηλος (kamēlos) from Ancient Semitic: gāmāl) is an even-toed ungulate in the genus Camelus that bears distinctive fatty deposits known as "humps" on its back. Camels have long been domesticated and, as livestock, they provide food (milk and meat) and textiles (fiber and felt from hair). Camels are working animals especially suited to their desert habitat and are a vital means of transport for passengers and cargo. There are three surviving species of camel.
DesertificationDesertification is a type of land degradation in drylands in which biological productivity is lost due to natural processes or induced by human activities whereby fertile areas become arid. It is the spread of arid areas caused by a variety of factors, such as climate change and overexploitation of soil as a result of human activity. Throughout geological history, the development of deserts has occurred naturally. In recent times, the potential influences of human activity, improper land management, deforestation and climate change on desertification is the subject of many scientific investigations.
Endorheic basinAn endorheic basin (ˌɛndoʊˈriː.ɪk; also endoreic basin and endorreic basin) is a drainage basin that normally retains water and allows no outflow to other, external bodies of water (e.g. rivers and oceans), instead, the water drainage flows into permanent and seasonal lakes and swamps that equilibrate through evaporation. Endorheic basins also are called closed basins, terminal basins, and internal drainage systems. Endorheic regions contrast with open lakes (exorheic regions), where surface waters eventually drain into the ocean.
Western SaharaWestern Sahara (الصحراء الغربية aṣ-Ṣaḥrā' al-Gharbiyyah; Taneẓroft Tutrimt ; Sáhara Occidental) is a disputed territory on the northwest coast and in the Maghreb region of North and West Africa. The Western Sahara, given its name in 1975 by the UN, is the last African colonial state yet to achieve its independence. About 20% of the territory is controlled by the self-proclaimed Sahrawi Arab Democratic Republic (SADR); the remaining 80% of the territory is occupied and administered by neighboring Morocco.

EcoregionAn ecoregion (ecological region) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions.
