Muninga
''Pterocarpus erinaceus'' is an endangered species of tree that is native to the Sahelian region of West Africa. It is listed in Appendix II of the CITES, Convention on International Trade in Endangered Species of Wild Fauna and Flora. It is used for fuel wood, for medicinal purposes, as a woodworking material, and is useful as a Nitrogen fixation, nitrogen-fixing plant to improve nutrient-depleted farming land. It has several common names, including kosso, barwood, African kino tree, muninga, and ''vène''; ''mukwa'' is used for this species as well as other ''Pterocarpus''. Groves of the tree can be found on the savannahs of West Africa, but it is becoming increasingly rare and is sometimes cultivated. The tree also grows in forests of Comoé National Park in Côte d'Ivoire, a region geographically close to the Sahel but with a higher moisture regime due to its location between two large rivers. Also, the tree grows in abundance in Kurmi Local Govt. of Taraba State in Nigeria. T ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pterocarpus
''Pterocarpus'' is a pantropical genus of trees in the family Fabaceae. It belongs to the subfamily Faboideae, and was recently assigned to the informal monophyletic ''Pterocarpus'' clade within the Dalbergieae. Most species of ''Pterocarpus'' yield valuable timber traded as padauk (or padouk); other common names are mukwa or narra. '' P. santalinus'' also yields the most precious red sandalwood in China known as Zitan. The wood from the narra tree ('' P. indicus'') and the Burmese padauk tree ('' P. macrocarpus'') is marketed as amboyna when it has grown in the burl form. The scientific name is Latinized Ancient Greek and means "wing fruit", referring to the unusual shape of the seed pods in this genus. Uses Padauk wood is obtained from several species of ''Pterocarpus''. All padauks are of African or Asian origin. Padauks are valued for their toughness, stability in use, and decorativeness, most having a reddish wood. Most Pterocarpus' woods contain either water- or alcohol-s ...

Djembe
A djembe or jembe ( ; from Maninka language, Malinke ''jembe'' , N'Ko script, N'Ko: ) is a rope-tuned skin-covered goblet drum played with bare hands, originally from West Africa. According to the Bambara people in Mali, the name of the djembe comes from the saying "Anke djé, anke bé" which translates to "everyone gather together in peace" and defines the drum's purpose. In the Bambara language, "djé" is the verb for "gather" and "bé" translates as "peace." The djembe has a body (or shell) carved of hardwood and a drumhead made of untreated (not Liming (leather processing), limed) Rawhide (textile), rawhide, most commonly made from Goatskin (material), goatskin. Excluding rings, djembes have an exterior diameter of 30–38 cm (12–15 in) and a height of 58–63 cm (23–25 in). The majority have a diameter in the 13 to 14 inch range.

Serer Language
Serer, often broken into differing regional dialects such as Serer-Sine and Serer saloum, is a language of the kingdoms of Sine and Saloum branch of Niger–Congo spoken by 1.2 million people in Senegal and 30,000 in the Gambia as of 2009. It is the principal language of the Serer people. Classification Serer is one of the Senegambian languages, which are characterized by consonant mutation. The traditional classification of Atlantic is that of Sapir (1971), which found that Serer was closest to Fulani. However, a widely cited misreading of the data by Wilson (1989) inadvertently exchanged Serer for Wolof. Dialects of Serer are Serer Sine (the prestige dialect), Segum, Fadyut-Palmerin, Dyegueme (Gyegem), and Niominka. They are mutually intelligible except for the Sereer spoken in some of the areas surrounding the city of Thiès. Not all Serer people speak Serer. About 200,000 speak Cangin languages. Because the speakers are ethnically Serer, they are commonly thought to be S ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Wolof Language
Wolof (; Wolofal: ) is a language of Senegal, Mauritania, and the Gambia, and the native language of the Wolof people. Like the neighbouring languages Serer and Fula, it belongs to the Senegambian branch of the Niger–Congo language family. Unlike most other languages of the Niger-Congo family, Wolof is not a tonal language. Wolof is the most widely spoken language in Senegal, spoken natively by the Wolof people (40% of the population) but also by most other Senegalese as a second language. Wolof dialects vary geographically and between rural and urban areas. The principal dialect of Dakar, for instance, is an urban mixture of Wolof, French, and Arabic. ''Wolof'' is the standard spelling and may also refer to the Wolof ethnicity or culture. Variants include the older French , , , Gambian Wolof, etc., which now typically refers either to the Jolof Empire or to jollof rice, a common West African rice dish. Now-archaic forms include ''Volof'' and ''Olof''. English is believed ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Zarma Language
Zarma (also spelled Djerma, Jerma, Dyabarma, Dyarma, Dyerma, Adzerma, Zabarma, Zarbarma, Zarmaci or Zerma) is one of the Songhay languages. It is the leading indigenous language of the southwestern lobe of the West African nation of Niger, where the Niger River flows and the capital city, Niamey, is located. Zarma is the second-most common language in the country, after Hausa, which is spoken in south-central Niger. With over 2 million speakers, Zarma is easily the most widely spoken Songhay language.

Fula Language
Fula ,Laurie Bauer, 2007, ''The Linguistics Student’s Handbook'', Edinburgh also known as Fulani or Fulah (, , ; Adlam: , , ), is a Senegambian language spoken by around 30 million people as a set of various dialects in a continuum that stretches across some 18 countries in West and Central Africa. Along with other related languages such as Serer and Wolof, it belongs to the Atlantic geographic group within Niger–Congo, and more specifically to the Senegambian branch. Unlike most Niger-Congo languages, Fula does not have tones. It is spoken as a first language by the Fula people ("Fulani", ff, Fulɓe, link=no) from the Senegambia region and Guinea to Cameroon, Nigeria, and Sudan and by related groups such as the Toucouleur people in the Senegal River Valley. It is also spoken as a second language by various peoples in the region, such as the Kirdi of northern Cameroon and northeastern Nigeria.

Global Warming
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

Environmental Degradation
Environmental degradation is the deterioration of the environment (biophysical), environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable. Environmental concerns can be defined as the negative effects of any human activity on the environment. The biological as well as the physical features of the environment are included. Some of the primary environmental challenges that are causing great worry are air pollution, water pollution, natural environment pollution, rubbish pollution, and so o Environmental degradation is one of the ten threats officially cautioned by the High-level Panel on Threats, Challenges and Change, high-level PaneI on Threats, Challenges and Change of the United Nations.

Overexploitation
Overexploitation, also called overharvesting, refers to harvesting a renewable resource to the point of diminishing returns. Continued overexploitation can lead to the destruction of the resource, as it will be unable to replenish. The term applies to natural resources such as water aquifers, grazing pastures and forests, wild medicinal plants, fish stocks and other wildlife. In ecology, overexploitation describes one of the five main activities threatening global biodiversity. Ecologists use the term to describe populations that are harvested at an unsustainable rate, given their natural rates of mortality and capacities for reproduction. This can result in extinction at the population level and even extinction of whole species. In conservation biology, the term is usually used in the context of human economic activity that involves the taking of biological resources, or organisms, in larger numbers than their populations can withstand. The term is also used and defined some ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Mungo Park (explorer)
Mungo Park (11 September 1771 – 1806) was a Scottish explorer of West Africa. After an exploration of the upper Niger River around 1796, he wrote a popular and influential travel book titled ''Travels in the Interior Districts of Africa'' in which he theorized the Niger and Congo merged to become the same river. He was killed during a second expedition, having successfully traveled about two-thirds of the way down the Niger. With Park's death, the idea of a Niger-Congo merger remained an open question although it became the leading theory among geographers. The mystery of the Niger's course, which had been speculated about since the Ancient Greeks and was second only to the mystery of the Nile's source, was not solved for another 25 years, in 1830, when it was discovered the Niger and Congo were in fact separate rivers. If the African Association was the "beginning of the age of African exploration" then Mungo Park was its first successful explorer; he set a standard for al ...
