Djoudj National Bird Sanctuary
The Djoudj National Bird Sanctuary (french: Parc national des oiseaux du Djoudj, ) lies on the southeast bank of the Senegal River in Senegal, in northern Biffeche, north east of St-Louis. It provides a range of wetland habitats which prove very popular with migrating birds, many of which have just crossed the Sahara. Of almost 400 species of birds, the most visible are pelicans and flamingos. Less conspicuous are the aquatic warblers migrating here from Europe; for these, the park is the single most important wintering site yet discovere A wide range of wildlife also inhabits the park, which is designated a World Heritage Site. The site was added to the list of World Heritage in Danger in 2000 due to the introduction of the invasive giant salvinia plant, which threatens to choke out the park's native vegetation. However it was removed from the list in 2006. Environmental issues Since operation of the Diama Dam on the Senegal River began in 1988, experts have observed a lowerin ...

World Heritage Site
A World Heritage Site is a landmark or area with legal protection by an international convention administered by the United Nations Educational, Scientific and Cultural Organization (UNESCO). World Heritage Sites are designated by UNESCO for having cultural, historical, scientific or other form of significance. The sites are judged to contain " cultural and natural heritage around the world considered to be of outstanding value to humanity". To be selected, a World Heritage Site must be a somehow unique landmark which is geographically and historically identifiable and has special cultural or physical significance. For example, World Heritage Sites might be ancient ruins or historical structures, buildings, cities, deserts, forests, islands, lakes, monuments, mountains, or wilderness areas. A World Heritage Site may signify a remarkable accomplishment of humanity, and serve as evidence of our intellectual history on the planet, or it might be a place of great natural beauty. A ...

Wildlife Of Senegal
Wildlife refers to undomesticated animal species, but has come to include all organisms that grow or live wild in an area without being introduced by humans. Wildlife was also synonymous to game: those birds and mammals that were hunted for sport. Wildlife can be found in all ecosystems. Deserts, plains, grasslands, woodlands, forests, and other areas, including the most developed urban areas, all have distinct forms of wildlife. While the term in popular culture usually refers to animals that are untouched by human factors, most scientists agree that much wildlife is affected by human activities. Some wildlife threaten human safety, health, property, and quality of life. However, many wild animals, even the dangerous ones, have value to human beings. This value might be economic, educational, or emotional in nature. Humans have historically tended to separate civilization from wildlife in a number of ways, including the legal, social, and moral senses. Some animals, howeve ...

Diawling National Park
The Diawling National Park lies in south west Mauritania around the Senegal River delta. During the rainy season, much of the park consists of large lakes. It is known for having over 220 species of identified birds, including pelicans, black storks, and flamingos, and also for its fish. Geography and establishment Diawling National Park was established in 1991. The park sprawls over an area of 16,000 hectares, all of which was once a floodplain. The Senegal River acts like a boundary between the park and the Djoudj National Bird Sanctuary, which was established in 1971. The Djoudj National Bird Sanctuary is located in the Republic of Senegal. The opposition to the establishment of the Diawling National Park came mostly from the local inhabitants, who feared a similar fate as that of the populace of Djoudj. They were fearful of the consequences of a protected area, which would mean that grazing and fishing would be prohibited or limited, ending a way of life that their tribes had ...

Phragmites
''Phragmites'' () is a genus of four species of large perennial reed grasses found in wetlands throughout temperate and tropical regions of the world. Taxonomy The World Checklist of Selected Plant Families, maintained by Kew Garden in London, accepts the following four species: * ''Phragmites australis'' ( Cav.) Trin. ex Steud. – cosmopolitan * ''Phragmites japonicus'' Steud. – Japan, Korea, Ryukyu Islands, Russian Far East * ''Phragmites karka'' ( Retz.) Trin. ex Steud. – tropical Africa, southern Asia, Australia, some Pacific Islands, invasive in New Zealand * ''Phragmites mauritianus'' Kunth – central + southern Africa, Madagascar, Mauritius The cosmopolitan common reed has the generally accepted botanical name ''Phragmites australis''. (Cav.) Trin. ex Steud. About 130 other synonyms have been proposed. Examples include ''Phragmites communis'' Trin., ''Arundo phragmites'' L., and ''Phragmites vulgaris'' (Lam.) Crép.

Typha
''Typha'' is a genus of about 30 species of monocotyledonous flowering plants in the family Typhaceae. These plants have a variety of common names, in British English as bulrush or reedmace, in American English as reed, cattail, or punks, in Australia as cumbungi or bulrush, in Canada as bulrush or cattail, and in New Zealand as raupo. Other taxa of plants may be known as bulrush, including some sedges in ''Scirpus'' and related genera. The genus is largely distributed in the Northern Hemisphere, where it is found in a variety of wetland habitats. The rhizomes are edible. Evidence of preserved starch grains on grinding stones suggests they were already eaten in Europe 30,000 years ago. Description ''Typha'' are aquatic or semi-aquatic, rhizomatous, herbaceous perennial plants. The leaves are glabrous (hairless), linear, alternate and mostly basal on a simple, jointless stem that bears the flowering spikes. The plants are monoecious, with unisexual flowers that develop in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silting
Siltation, is water pollution caused by particulate terrestrial clastic material, with a particle size dominated by silt or clay. It refers both to the increased concentration of suspended sediments and to the increased accumulation (temporary or permanent) of fine sediments on bottoms where they are undesirable. Siltation is most often caused by soil erosion or sediment spill. It is sometimes referred to by the ambiguous term "sediment pollution", which can also refer to a chemical contamination of sediments accumulated on the bottom, or to pollutants bound to sediment particles. Although "siltation" is not perfectly stringent, since it also includes particle sizes other than silt, it is preferred for its lack of ambiguity. Causes The origin of the increased sediment transport into an area may be erosion on land or activities in the water. In rural areas, the erosion source is typically soil degradation by intensive or inadequate agricultural practices, leading to soil eros ...

Desalinization
Desalination is a process that takes away mineral components from saline water. More generally, desalination refers to the removal of salts and minerals from a target substance, as in soil desalination, which is an issue for agriculture. Saltwater (especially sea water) is desalinated to produce water suitable for human consumption or irrigation. The by-product of the desalination process is brine. Desalination is used on many seagoing ships and submarines. Most of the modern interest in desalination is focused on cost-effective provision of fresh water for human use. Along with recycled wastewater, it is one of the few rainfall-independent water resources. Due to its energy consumption, desalinating sea water is generally more costly than fresh water from surface water or groundwater, water recycling and water conservation. However, these alternatives are not always available and depletion of reserves is a critical problem worldwide. Desalination processes are using either the ...

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 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$149.5 million loa ...
