Pterocarpus Erinaceus
''Pterocarpus erinaceus'' is an endangered tree species native to the Sahelian region of West Africa. It is listed in Appendix II of the 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-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. The tree grows to about 11 meters in h ...

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."

Flora Of Ivory Coast
The wildlife of Ivory Coast consists of the flora and fauna of this nation in West Africa. The country has a long Atlantic coastline on the Gulf of Guinea and a range of habitat types. Once covered in tropical rainforest, much of this habitat has been cleared, the remaining terrain being gallery forests and savanna with scattered groups of trees, resulting in a decrease in biodiversity. As of 2016, 252 species of mammal had been recorded in Ivory Coast, 666 species of bird, 153 species of reptile, 80 species of amphibian, 671 species of fish and 3660 species of vascular plant. Geography Ivory Coast is a country in western sub-Saharan Africa just north of the equator, bordered by Liberia and Guinea to the west, Mali and Burkina Faso to the north and Ghana to the east. To the south lies the Gulf of Guinea with a coastline where there is a network of lagoons. The land rises from south to north, the terrain being mostly flat to undulating plain, with mountains in the west and nort ...

Trees Of Africa
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported clear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of West Tropical Africa
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) wa ...

Serer Language
Serer, often broken into differing regional dialects such as Serer-Sine and Serer-Saloum, is a language of the Senegambian branch of the Niger–Congo family 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, and was the language of the early modern kingdoms of Sine, Saloum, and Baol. Serer is primarily written in the Latin alphabet. Classification Serer is one of the Senegambian languages, which are characterized by consonant mutation. The traditional classification of Atlantic languages 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wolof Language
Wolof ( ; , ) is a Niger–Congo language spoken by the Wolof people in much of the West African subregion of Senegambia that is split between the countries of Senegal, The Gambia and Mauritania. Like the neighbouring languages Serer and Fula, it belongs to the Senegambian branch of the Niger–Congo language family. Unlike most other languages of its 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 , , or , which now typically refers either to the Jolof Empire or to jollof rice, a common West African rice dish. Now-archaic forms incl ...

Global Warming
Present-day climate change includes both global warming—the ongoing increase in global average temperature—and its wider 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 temperatures is driven by human activities, especially fossil fuel burning since the Industrial Revolution. Fossil fuel use, deforestation, and some agricultural and industrial practices release greenhouse gases. These gases absorb some of the heat that the Earth radiates after it warms from sunlight, warming the lower atmosphere. Carbon dioxide, the primary gas driving global warming, has increased in concentration by about 50% since the pre-industrial era to levels not seen for millions of years. Climate change has an increasingly large impact on the environment. Deserts are expanding, while heat waves and wildfires are becoming more common. Amplified warming in the Arctic has c ...

Overexploitation
Overexploitation, also called overharvesting or ecological overshoot, 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.
