Tropical Africa
Although tropical Africa is mostly familiar to the West for its rainforests, this biogeographic realm of Africa is far more diverse. While the tropics are thought of as regions with hot moist climates, which are caused by latitude and the tropical rain belt, the geology of areas, particularly mountain chains, and geographical relation to continental and regional scale winds impact the overall areas , also, making the tropics run from arid to humid in West Africa. The area is currently experiencing the negative effects of rapid human population growth.Zinkina J., Andrey Korotayev, Korotayev A.]Explosive Population Growth in Tropical Africa: Crucial Omission in Development Forecasts (Emerging Risks and Way Out). ''World Futures'' 70/2 (2014): 120–139 Overview Tropical rainforests are moist forests of semi-deciduous plants distributed across nine West African countries.

Bergenin
Bergenin, alias cuscutin, is trihydroxybenzoic acid glycoside. It is the C-glycoside of 4-O-methyl gallic acid. It possesses an O-demethylated derivative called norbergenin. These are chemical compounds and drugs of Ayurveda, commonly known as Paashaanbhed. It shows a potent immunomodulatory effect. Bergenin can be isolated from ''Bergenia'' species like ''Bergenia ciliata'' and ''Bergenia ligulata'', from rhizomes of ''Bergenia stracheyi''. It is also found in the stem bark of ''Dryobalanops aromatica'', in ''Ardisia elliptica'' and in ''Mallotus japonicus ''Mallotus japonicus'' (), also known as East Asian mallotus, the food wrapper plant or "Akamegashiwa" in Japanese, is a plant species in the genus '' Mallotus'' native to China.

Palm Wine
Palm wine, known by several local names, is an alcoholic beverage created from the sap of various species of palm tree such as the palmyra, date palms, and coconut palms. It is known by various names in different regions and is common in various parts of Africa, the Caribbean, South America, South Asia, Southeast Asia and Micronesia. Palm wine production by smallholders and individual farmers may promote conservation as palm trees become a source of regular household income that may economically be worth more than the value of timber sold. Tapping The sap is extracted and collected by a tapper. Typically the sap is collected from the cut flower of the palm tree. A container is fastened to the flower stump to collect the sap. The white liquid that initially collects tends to be very sweet and non- alcoholic before it is fermented. An alternative method is the felling of the entire tree. Where this is practised, a fire is sometimes lit at the cut end to facilitate th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lopé National Park
Lopé National Park is a national park in central Gabon. Bordered by the Ogooué River to the north and the Chaillu Massif to the south, the park takes up roughly 4912 square kilometers. Although the terrain is mostly monsoon forest, in the north the park contains the last remnants of grass savannas created in Central Africa during the last ice age, 15,000 years ago. It was the first protected area in Gabon when the Lopé-Okanda Wildlife Reserve was created in 1946, and in 2007, the national park and surrounding Lopé-Okanda landscape were added to the World Heritage List by UNESCO because of its biodiversity, unique savanna-forest transitional zone, and the spectacular petroglyphs in the region. Ecology Lopé National Park has dry weather compared to the rest of Gabon, being located in the rain shadow of the Chaillu Massif. In addition, there a low band of rainfall along the Ogooué River. As a result, the landscape contains a complex mosaic of dense tropical rainforests and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firewood
Firewood is any wooden material that is gathered and used for fuel. Generally, firewood is not highly processed and is in some sort of recognizable log or branch form, compared to other forms of wood fuel like pellets or chips. Firewood can be seasoned and heat treated (dry) or unseasoned (fresh/wet). It is generally classified as hardwood or softwood. Firewood is a renewable resource. However, demand for this fuel can outpace its ability to regenerate on a local or regional level. Good forestry practices and improvements in devices that use firewood can improve local wood supplies. Moving firewood long distances can potentially transport diseases and invasive species. History For most of human history firewood was the main fuel, until the use of coal spread during the Industrial Revolution. As such, access to firewood was a valued resource, wood botes or the right to gather firewood being a significant aspect of many medieval leases. As late as 19th C America, Th ...

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''. 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) was first made by Jules Thurma ...
