Saint-Louis, Senegal
Saint Louis or Saint-Louis ( wo, Ndar), is the capital of Senegal's Saint-Louis Region. Located in the northwest of Senegal, near the mouth of the Senegal River, and 320 km north of Senegal's capital city Dakar, it has a population officially estimated at 258,592 in 2021. Saint-Louis was the capital of the French colony of Senegal from 1673 until 1902 and French West Africa from 1895 until 1902, when the capital was moved to Dakar. From 1920 to 1957, it also served as the capital of the neighboring colony of Mauritania. The town was an important economic center during French West Africa, but it is less important now. However it still has important industries, including tourism, a commercial center, a center of sugar production, and fishing. The Tourism industry is in part due to the city being listed as a UNESCO World Heritage Site in 2000. However, the city is also Climate change vulnerability, vulnerable to climate change—where sea level rise is expected to threaten the ci ...

Organisation Pour La Mise En Valeur Du Fleuve Sénégal
The ''Organisation pour la mise en valeur du fleuve Sénégal'' (OMVS; in English Senegal River Basin Development Authority) is an organisation grouping Guinea, Mali, Mauritania and Senegal for the purpose of jointly managing the Senegal River and its drainage basin. In 1963 a predecessor organization was established, the ''Organisation des Etats Riverians du Fleuve Sénégal'' (or the Senegal River Riparian States Organization), with the four border countries—Guinea, Mali, Mauritania, and Senegal—to manage the Sénégal River drainage basin and the river itself. This organization dissolved when Guinea withdrew due to political tensions and the three remaining countries subsequently created the OMVS. Guinea returned to the organisation in 2006. The OMVS aims to promote ''self-sufficiency in'' food security, to improve the income of the local populations, and to preserve the natural ecosystems. The area has a total population of 35 million inhabitants, of whom 12 million live in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semefé River
The Bakoy or Bakoye River is a river in West Africa. It runs through Guinea and Mali and joins with the Bafing River to form the Sénégal River at Bafoulabé in the Kayes Region of western Mali. In Manding languages, Bakoye signifies 'white river', Bafing 'black river' and Baloué 'red river'.. The source of the Bakoy is at an elevation of 760 m in the granite Monts Ménien to the northwest of Siguiri in Guinea. The river flows north and forms part of the international border between Guinea and Mali. It then meanders across the Manding Plateau and joins its principal affluent, the Baloué, which rises to the west of Bamako.. The Bakoy is 560 km in length and drains a basin of around 85,600 km2. The river is seasonal with a maximum flow in September after the start of the West African Monsoon and almost no flow between January and June. The large year-to-year variation in the intensity of the West African Monsoon gives rise to large changes in the discharge of th ...

Headwater
The headwaters of a river or stream is the farthest place in that river or stream from its estuary or downstream confluence with another river, as measured along the course of the river. It is also known as a river's source. Definition The United States Geological Survey (USGS) states that a river's "length may be considered to be the distance from the mouth to the most distant headwater source (irrespective of stream name), or from the mouth to the headwaters of the stream commonly known as the source stream". As an example of the second definition above, the USGS at times considers the Missouri River as a tributary of the Mississippi River. But it also follows the first definition above (along with virtually all other geographic authorities and publications) in using the combined Missouri—lower Mississippi length figure in lists of lengths of rivers around the world. Most rivers have numerous tributaries and change names often; it is customary to regard the longest t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gouina Falls
The Gouina Falls or ''Chutes de Gouina'' are on the Sénégal River in Mali between the towns of Bafoulabé (upstream) and Diamou (downstream) in the Kayes Region, where the river runs north from the Talari Gorges. They have been called the "Niagara falls of Mali". The river is about 500 m wide at this point, and drops 16 m over the falls. The volume of water is 12-13 m3 per second in the dry season, and up to 2430 m3 per second in the rainy season. The government of Mali and Senegal River Basin Development Authority has investigated the possibility of developing the electric power potential of the Senegal River. Downstream on the Félou Falls, a new Félou Hydroelectric Plant was completed in 2014. On Gouina Falls, construction of the 140 MW Gouina Hydroelectric Plant The Gouina Hydroelectric Plant is a run-of-the-river-type hydroelectric installation currently being constructed on Gouina Falls along the Senegal River in Mali. It is located about south ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gouina Hydroelectric Plant
The Gouina Hydroelectric Plant is a run-of-the-river-type hydroelectric installation currently being constructed on Gouina Falls along the Senegal River in Mali. It is located about southeast of Diamou in the Kayes Region. It is the fourth project of the Senegal River Basin Development Authority and its ground-breaking ceremony on 17 December 2013 was attended by the heads of state of each member country. Mauritanian President Mohamed Ould Abdel Aziz laid the foundation stone. Preliminary construction had been suspended due to the 2012 Malian coup d'état and subsequent Northern Mali conflict. The plant is expected to be complete in 2020 and will provide power to Mauritania, Mali and Senegal. The plant will cost US$329 million and the of transmission lines will cost US$65 million. The project is receiving 85 percent of its funding from the Exim Bank of China along with US$1 million from the EU-Africa Infrastructure Trust Fund and US$1.4 million from the International Development ...

Félou Hydroelectric Plant
The Félou Hydroelectric Plant is a hydroelectric installation at the Félou Falls on the Sénégal River in Mali. It has three water turbines capable of generating 62.3 MW. The current power station replaced an older one built in the 1920s. Construction of the new power station began in October 2009 and was financed by the World Bank. It is the third Senegal River Basin Development Authority project on the river and was completed in 2014. The existing weir was refurbished with the previous height maintained. In 1927, the previous hydroelectric power station was commissioned. It was refurbished in 1992 and had an installed capacity of 600 kW. At maximum output the three 21 MW turbines pass a total of of water. Between August and November the water flowing in the river generally exceeds this value allowing the plant to operate at full capacity and the excess water to pass over the weir. During the dry season (December to July) the electricity generated is reduced to ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maka-Diama Dam
The Diama Dam, sometimes referred to as the Maka–Diama Dam, is a gravity dam on the Senegal River, spanning the border of Senegal and Mauritania. It is located next to the town of Diama, Senegal and about north of Saint-Louis, Senegal. The purpose of the dam is to prevent saltwater intrusion upstream, supply water for the irrigation of about of crops and create a road crossing for the road between St. Louis and Nouakchott in Mauritania. Additionally, a ship lock built within the dam provides for navigability, navigation upstream. Plans for the dam were first drawn in 1970 when the riparian states within the Senegal River Basin Development Authority agreed to develop the Senegal River. The Diama Dam was to be constructed in conjunction with the Manantali Dam which was to be located further upstream in Mali. Construction on the Diama Dam began on 15 September 1981 and was completed on 12 August 1986. The Manantali Dam was completed in 1988. The Diama project was funded by a US$149 ...

Manantali Dam
The Manantali Dam is a multi-purpose dam on the Bafing river in the Senegal River basin, to the south-east of Bafoulabé, in Mali's Kayes Region. History Early planning for the dam began in 1972 when the Organization for the Development of the Senegal River (Organisation pour la mise en valeur du fleuve Sénégal, or OMVS) was set up by Mali, Mauritania and Senegal to develop the agricultural and hydropower potential of the basin. The World Bank declined to fund the dam in 1979, considering it an unreasonable investment. However, financing was secured mainly from Europe and construction on the dam began in 1982. It was completed in 1988, but without the hydropower plant. In 1989 the Mauritania–Senegal Border War stopped all work on the project. A Swiss journalist who visited Manantali in 1988 described the project as a "luxury car without a motor". In 1993 Carl–Dieter Spranger, then Germany's minister for development assistance, called Manantali an "act of economic and enviro ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Freshwater Ecoregions In Africa And Madagascar
{{Short description, none This is a list of freshwater ecoregions in Africa and Madagascar, as identified by the World Wildlife Fund (WWF). The WWF divides the Earth's land surface into ecoregions, defined as "large area of land or water containing a distinct assemblage of natural communities and species". Ecoregions are grouped into bioregions, "a complex of ecoregions that share a similar biogeographic history, and thus often have strong affinities at higher taxonomic levels (e.g. genera, families)." The Earth's land surface is divided into eight biogeographic realms. Most of Africa lies in the Afrotropical realm, although the freshwater ecoregions of North Africa have much in common with the Palearctic. Each ecoregion is also classified into major habitat types, or biomes. Many consider this classification to be quite decisive, and some propose these as stable borders for bioregional democracy initiatives. by Bioregion North African * Canary Islands * Horn (Djibouti, Ethiopia, ...

Ecoregion
An ecoregion (ecological region) or ecozone (ecological zone) 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. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
