History Of Central Africa
The history of Central Africa has been divided into its prehistory, its ancient history, the major polities flourishing, the colonial period, and the post-colonial period, in which the current nations were formed. Central Africa is the central region of Africa, bordered by North Africa, West Africa, East Africa, Southern Africa, the Atlantic Ocean, and the Sahara Desert. Colonial boundaries are reflected in the modern boundaries between contemporary Central African states, cutting across ethnic and cultural lines, often dividing single ethnic groups between two or more states. Geography The area located at the south of the desert is a steppe, a semi-arid region, called the Sahel. It is the ecoclimatic and ecoregion, biogeographic zone of ecotone, transition in Africa between the Sahara desert to the north and the Sudanian Savanna to the south. The Sudanian Savanna is a broad belt of tropical and subtropical grasslands, savannas, and shrublands, tropical savanna that spans the ...

Ethiopian Highlands
The Ethiopian Highlands (also called the Abyssinian Highlands) is a rugged mass of mountains in Ethiopia in Northeast Africa. It forms the largest continuous area of its elevation in the continent, with little of its surface falling below , while the summits reach heights of up to . It is sometimes called the "Roof of Africa" due to its height and large area. It is the only country in the region with such a high elevated surface. This elevated surface is bisected diagonally by the Great East African Rift System which extends from Syria to Mozambique across the East African Lakes. Most of the Ethiopian Highlands are part of central and northern Ethiopia, and its northernmost portion reaches into Eritrean Highlands, Eritrea. History In the southern parts of the Ethiopian Highlands once was located the Kingdom of Kaffa, a medieval and Early modern period, early modern state, whence the coffee plant was exported to the Arabian Peninsula. The land of the former kingdom is mountainou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fishing
Fishing is the activity of trying to catch fish. Fish are often caught as wildlife from the natural environment (Freshwater ecosystem, freshwater or Marine ecosystem, marine), but may also be caught from Fish stocking, stocked Body of water, bodies of water such as Fish pond, ponds, canals, park wetlands and reservoirs. Fishing techniques include trawling, Longline fishing, longlining, jigging, Fishing techniques#Hand-gathering, hand-gathering, Spearfishing, spearing, Fishing net, netting, angling, Bowfishing, shooting and Fish trap, trapping, as well as Destructive fishing practices, more destructive and often Illegal, unreported and unregulated fishing, illegal techniques such as Electrofishing, electrocution, Blast fishing, blasting and Cyanide fishing, poisoning. The term fishing broadly includes catching aquatic animals other than fish, such as crustaceans (shrimp/lobsters/crabs), shellfish, cephalopods (octopus/squid) and echinoderms (starfish/sea urchins). The term is n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Harpoons
A harpoon is a long, spear-like projectile used in fishing, whaling, sealing, and other hunting to shoot, kill, and capture large fish or marine mammals such as seals, sea cows, and whales. It impales the target and secures it with barb or toggling claws, allowing the fishermen or hunters to use an attached rope or chain to pull and retrieve the animal. A harpoon can also be used as a ranged weapon against other watercraft in naval warfare. Certain harpoons are made with different builds to perform better with the type of target. For example, the Inuit have short, fixed-foreshaft harpoons for hunting at breathing holes, while loose-shafted ones are made for throwing and remaining attached to the game. History In the 1990s, harpoon points, known as the Semliki harpoons or the Katanda harpoons, were found in the Katanda region in Zaire. As the earliest known harpoons, these weapons were made and used 90,000 years ago, most likely to spear catfishes. Later, in Japan, spea ...

Hominins
The Hominini (hominins) form a taxonomic tribe of the subfamily Homininae (hominines). They comprise two extant genera: ''Homo'' (humans) and '' Pan'' (chimpanzees and bonobos), and in standard usage exclude the genus ''Gorilla'' (gorillas), which is grouped separately within the subfamily Homininae. The term Hominini was originally introduced by Camille Arambourg (1948), who combined the categories of ''Hominina'' and ''Simiina'' pursuant to Gray's classifications (1825). Traditionally, chimpanzees, gorillas and orangutans were grouped together, excluding humans, as pongids. Since Gray's classifications, evidence accumulating from genetic phylogeny confirmed that humans, chimpanzees, and gorillas are more closely related to each other than to the orangutan. The orangutans were reassigned to the family Hominidae (great apes), which already included humans; and the gorillas were grouped as a separate tribe (Gorillini) of the subfamily Homininae. Still, details of this re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Democratic Republic Of Congo
The Democratic Republic of the Congo (DRC), also known as the DR Congo, Congo-Kinshasa, or simply the Congo (the last ambiguously also referring to the neighbouring Republic of the Congo), is a country in Central Africa. By land area, it is the second-largest country in Africa and the 11th-largest in the world. With a population of around 112 million, the DR Congo is the most populous nominally Francophone country in the world. French is the official and most widely spoken language, though there are over 200 indigenous languages. The national capital and largest city is Kinshasa, which is also the economic center. The country is bordered by the Republic of the Congo, the Cabinda exclave of Angola, and the South Atlantic Ocean to the west; the Central African Republic and South Sudan to the north; Uganda, Rwanda, Burundi, and Tanzania (across Lake Tanganyika) to the east; and Zambia and Angola to the south. Centered on the Congo Basin, most of the country's terrain is co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ishango
Ishango is a Congolese lakeshore site located in the north-eastern region of the Democratic Republic of Congo in Africa, previously known as Zaire. This present day village is known as a "fishermen settlement" as it lies on the shores of the Semliki River, flowing out of Lake Edward, serving as one of the sources of the Nile River.Pletser, Vladimir & Huylebrouck, Dirk. (1999). The Ishango artefact: the missing base 12 link. Forma. 14. 339-346. This site is known best for its rich biodiversity and archaeological significance, indicating previous human occupation. Virunga National Park Ishango is a sub-station of the Virunga National Park, covering more than 13% of the North-Kivu province with about 790,000 hectares of extended landscape. Located at the mouth of Lake Edward, the Virunga National Park was established in 1925 in an effort to protect mountain gorilla species from threats of poaching and deforestation, making it the "oldest protected park in Africa".

Shrubland
Shrubland, scrubland, scrub, brush, or bush is a plant community characterized by vegetation dominance (ecology), dominated by shrubs, often also including grasses, herbaceous plant, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or it may be a transitional community that occurs temporarily as the result of a disturbance, such as fire. A stable state may be maintained by regular natural disturbance such as fire or browsing (predation), browsing. Shrubland may be unsuitable for human habitation because of the danger of fire. The term was coined in 1903. Shrubland species generally show a wide range of adaptations to fire, such as heavy seed production, lignotubers, and fire-induced germination. Botanical structural form In botany and ecology a shrub is defined as a much-branched woody plant less than 8 m high, usually with many plant stem, ...

Grassland
A grassland is an area where the vegetation is dominance (ecology), dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes such as clover, and other Herbaceous plant, herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on Earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures." (Pilot Assessm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wetlands
A wetland is a distinct semi-aquatic ecosystem whose groundcovers are flooded or saturated in water, either permanently, for years or decades, or only seasonally. Flooding results in oxygen-poor ( anoxic) processes taking place, especially in the soils. Wetlands form a transitional zone between waterbodies and dry lands, and are different from other terrestrial or aquatic ecosystems due to their vegetation's roots having adapted to oxygen-poor waterlogged soils. They are considered among the most biologically diverse of all ecosystems, serving as habitats to a wide range of aquatic and semi-aquatic plants and animals, with often improved water quality due to plant removal of excess nutrients such as nitrates and phosphorus. Wetlands exist on every continent, except Antarctica. The water in wetlands is either freshwater, brackish or saltwater. The main types of wetland are defined based on the dominant plants and the source of the water. For example, ''marshes'' are ...

Lakes
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of oceans or large ...
