Gouré
Goure (fr. Gouré) is a town in southeastern Niger, Zinder Region, Goure Department, of which it is the seat. Situation Situated on the main all-weather east–west highway in Southern Niger, it is about 170 km east of regional capital, Zinder, on the route east to Diffa, N'Guigmi, and the Lake Chad area along Niger's border with Chad. Around 40 km to the north of Goure are the Koutous hills, which form the first foothills of the Termit Massif. These hills also mark the northeastern boundary of Hausa settlement in Niger, with the desert and hills to the north sparsely populated by seasonal nomadic encampments, and the area to the east populated by a majority of settled Kanouri ethnic groups and Toubou pastoralists. Agriculture and environment The surrounding land is mostly dry grass Sahel dotted with acacia trees, with green patches formed by kouris (seasonal watercourses with underground water) and cuvettes (natural depressions which retain seasonal rain wat ...

Regions Of Niger
Niger is divided into eight regions (French: ''régions;'' singular''région)'', each of which is named after its capital. Current regions *Additionally, the national capital, Niamey, comprises a special capital district. Current administrative structure Each of Niger's regions are subdivided into departments and communes. As of 2005, there were 36 ''départements'', divided into 265 communes, 122 cantons and 81 ''groupements''. The latter two categories cover all areas not covered by urban communes (population over 10000) or rural communes (total population 13 million), and are governed by the department, whereas communes have had elected councils and mayors since 1999. Additional semi-autonomous subdivisions include sultanates, provinces and tributaries (''tribus''). The Nigerien government estimates there are an additional 17000 villages administered by rural communes, while there are a number of ''quartiers'' (boroughs or neighborhoods) administered by urban communes.

Kanouri
The Kanuri people (Kanouri, Kanowri, also Yerwa, Baribari and several subgroup names) are an African ethnic group living largely in the lands of the former Kanem and Bornu Empires in Niger, Nigeria, Sudan, Libya and Cameroon. Those generally termed Kanuri include several subgroups and dialect groups, some of whom identify as distinct from the Kanuri. Most trace their origins to ruling lineages of the medieval Kanem-Bornu Empire, and its client states or provinces. In contrast to the neighboring Toubou or Zaghawa pastoralists, Kanuri groups have traditionally been sedentary, engaging in farming, fishing the Chad Basin, and engaged in trade and salt processing. Background Kanuri peoples include several subgroups, and identify by different names in some regions. The Kanuri language was the major language of the Bornu Empire and remains a major language in southeastern Niger, northeastern Nigeria and northern Cameroon, but in Chad it is limited to a handful of speakers in urban ...

ICAO Airport Code
The ICAO airport code or location indicator is a four-letter code designating aerodromes around the world. These codes, as defined by the International Civil Aviation Organization and published in ICAO Document 7910: ''Location Indicators'', are used by air traffic control and airline operations such as flight planning. ICAO codes are also used to identify other aviation facilities such as weather stations, international flight service stations or area control centers, whether or not they are located at airports. Flight information regions are also identified by a unique ICAO-code. History The International Civil Aviation Organization was formed in 1947 under the auspices of the United Nations, and it established ''flight information regions'' (''FIR''s) for controlling air traffic and making airport identification simple and clear. ICAO codes versus IATA codes ICAO codes are separate and different from IATA codes, which are generally used for airline timetables, reserv ...

Locust
Locusts (derived from the Vulgar Latin ''locusta'', meaning grasshopper) are various species of short-horned grasshoppers in the family Acrididae that have a swarming phase. These insects are usually solitary, but under certain circumstances they become more abundant and change their behaviour and habits, becoming gregarious. No taxonomic distinction is made between locust and grasshopper species; the basis for the definition is whether a species forms swarms under intermittently suitable conditions; this has evolved independently in multiple lineages, comprising at least 18 genera in 5 different acridid subfamilies. Normally, these grasshoppers are innocuous, their numbers are low, and they do not pose a major economic threat to agriculture. However, under suitable conditions of drought followed by rapid vegetation growth, serotonin in their brains triggers dramatic changes: they start to breed abundantly, becoming gregarious and nomadic (loosely described as migratory) ...

Desertification
Desertification 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 increasingly 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. Definitions of words As recently as 2005, considerable controversy existed over the proper definition of the term "desertification." Helmut Geist (2005) identified more than 100 formal definitions. The most widely acceptedGeist (2005)p. 2/ref> of these was that of the Princeton University Dictionary which defined it as "the process of fertile land ''transforming into ...

Millet
Millets () are a highly varied group of small-seeded grasses, widely grown around the world as cereal crops or grains for fodder and human food. Most species generally referred to as millets belong to the tribe Paniceae, but some millets also belong to various other taxa. Millets are important crops in the semiarid tropics of Asia and Africa (especially in India, Mali, Nigeria, and Niger), with 97% of millet production in developing countries. This crop is favored due to its productivity and short growing season under dry, high-temperature conditions. Millets are indigenous to many parts of the world. The most widely grown millets are sorghum and pearl millets, which are important crops in India and parts of Africa. Finger millet, proso millet, and foxtail millet are also important crop species. Millets may have been consumed by humans for about 7,000 years and potentially had "a pivotal role in the rise of multi-crop agriculture and settled farming societies." Descript ...

Cuvettes
A cuvette ( French: cuvette = "little vessel") is a small tube-like container with straight sides and a circular or square cross section. It is sealed at one end, and made of a clear, transparent material such as plastic, glass, or fused quartz. Cuvettes are designed to hold samples for spectroscopic measurement, where a beam of light is passed through the sample within the cuvette to measure the absorbance, transmittance, fluorescence intensity, fluorescence polarization, or fluorescence lifetime of the sample. This measurement is done with a spectrophotometer. Overview Traditional ultraviolet–visible spectroscopy or fluorescence spectroscopy uses samples that are liquid. Often the sample is a solution, with the substance of interest dissolved within. The sample is placed in a cuvette and the cuvette is placed in a spectrophotometer for testing. The cuvette can be made of any material that is transparent in the range of wavelengths used in the test. The smallest cuvet ...

Wadi
Wadi ( ar, وَادِي, wādī), alternatively ''wād'' ( ar, وَاد), North African Arabic Oued, is the Arabic term traditionally referring to a valley. In some instances, it may refer to a wet (ephemeral) riverbed that contains water only when heavy rain occurs. Etymology The term ' is very widely found in Arabic toponyms. Some Spanish toponyms are derived from Andalusian Arabic where ' was used to mean a permanent river, for example: Guadalcanal from ''wādī al-qanāl'' ( ar, وَادِي الْقَنَال, "river of refreshment stalls"), Guadalajara from ''wādī al-ḥijārah'' ( ar, وَادِي الْحِجَارَة, "river of stones"), or Guadalquivir, from ''al-wādī al-kabīr'' ( ar, اَلْوَادِي الْكَبِير, "the great river"). General morphology and processes Wadis are located on gently sloping, nearly flat parts of deserts; commonly they begin on the distal portions of alluvial fans and extend to inland sabkhas or dry lakes.

Acacia
''Acacia'', commonly known as the wattles or acacias, is a large genus of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa and Australasia. The genus name is New Latin, borrowed from the Greek (), a term used by Dioscorides for a preparation extracted from the leaves and fruit pods of ''Vachellia nilotica'', the original type of the genus. In his ''Pinax'' (1623), Gaspard Bauhin mentioned the Greek from Dioscorides as the origin of the Latin name. In the early 2000s it had become evident that the genus as it stood was not monophyletic and that several divergent lineages needed to be placed in separate genera. It turned out that one lineage comprising over 900 species mainly native to Australia, New Guinea, and Indonesia was not closely related to the much smaller group of African lineage that contained ''A. nilotica''—the type species. This meant that the Australasian lineage (by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sahel
The Sahel (; ar, ساحل ' , "coast, shore") is a region in North Africa. It is defined as the ecoclimatic and biogeographic realm of transition between the Sahara to the north and the Sudanian savanna to the south. Having a hot semi-arid climate, it stretches across the south-central latitudes of Northern Africa between the Atlantic Ocean and the Red Sea. The Sahel part of Africa includes – from west to east – parts of northern Senegal, southern Mauritania, central Mali, northern Burkina Faso, the extreme south of Algeria, Niger, the extreme north of Nigeria, Cameroon and Central African Republic, central Chad, central and southern Sudan, the extreme north of South Sudan, Eritrea and Ethiopia. Historically, the western part of the Sahel was sometimes known as the Sudan region (''bilād as-sūdān'' "lands of the Sudan"). This belt was located between the Sahara and the coastal areas of West Africa. There are frequent shortages of food and water due to the dry h ...

Toubou
The 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) and the Dazagara (or Dazzaga, Dazagada, Daza). They are believed to share a common origin and speak the Tebu languages, which are from the Saharan branch of the Nilo-Saharan language family. Tebu is divided further into two closely related languages, called ''Tedaga'' (Téda Toubou) and ''Dazaga'' (Dazaga Gouran). Of the two groups, the Daza, found to the south of the Teda, are more numerous. The Toubou people are also referred to as the Tabu, Tebu, Tebou, Tibu, Tibbu, Toda, Todga, Todaga, Tubu, Tuda, Tudaga, or Gorane people. The Dazaga are ...

Hausa People
The Hausa ( autonyms for singular: Bahaushe ( m), Bahaushiya ( f); plural: Hausawa and general: Hausa; exonyms: Ausa; Ajami: ) are the largest native ethnic group in Africa. They speak the Hausa language, which is the second most spoken language after Arabic in the Afro-Asiatic language family. The Hausa are a diverse but culturally homogeneous people based primarily in the Sahelian and the sparse savanna areas of southern Niger and northern Nigeria respectively, numbering around 83 million people with significant indigenized populations in Benin, Cameroon, Ivory Coast, Chad, Sudan, Central African Republic, Republic of the Congo, Togo, Ghana, Eritrea, Equatorial Guinea, Gabon, Senegal and the Gambia. Predominantly Hausa-speaking communities are scattered throughout West Africa and on the traditional Hajj route north and east traversing the Sahara, with an especially large population in and around the town of Agadez. Other Hausa have also moved to large coastal cities in the re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
