In West Africa, the Dahomey Gap refers to the portion of the Guinean forest-savanna mosaic that extends all the way to the coast in Benin, Togo and Ghana, thus separating the forest zone that covers much of the south of the region into two separate parts. West Africa or Western Africa is the Westernmost Region of the African Continent. The Guinean forest-savanna mosaic is an Ecoregion of West Africa, consisting of interlaced Forest, Savanna, and Grassland, which divides Benin (bə'nɪn officially the Republic of Benin, and also known as Benin Republic, is a country in Western Africa. TOGO was a Japanese roller coaster design company famous for inventing the Stand-up roller coaster. The Republic of Ghana is a country in West Africa. It borders Côte d'Ivoire (Ivory Coast to the west Burkina Faso to the north Togo to the This article refers to the forest zone of Western Africa For Brazilian "forest zones" see Zona da Mata. The forest region west of the gap is called the Upper Guinean forests or Guinean forest zone, and the portion east of the gap is called the Lower Guinean forests, Lower Guinean-Congolian forests, or Congolian Forest Zone. The Upper Guinean forests is a tropical moist forest region of West Africa. The Lower Guinean forests is region of coastal tropical moist broadleaf forest extending along the coast of the Gulf of Guinea from eastern Benin through
The major city in the Gap is Accra. Accra is the capital, and most populous city of Ghana. The city also doubles as the capital of the Greater Several other cities, such as Kumasi, exist on the fringe of the Gap. Kumasi is a City in southern central Ghana. It is located near the Lake Bosomtwe, in the Rain Forest Region about 250 km (by road
The dryness of the Dahomey Gap is unusual, given that it lies surrounded by a very wet monsoon belt on all sides, and no mountains block moisture. A monsoon is a seasonal prevailing wind which lasts for several months Yet, Accra in the heart of the Gap receives only 720 millimetres (28 inches) of rainfall per year — less than half the amount needed to sustain tropical rainforest (which would be expected at a latitude of 6° N).
The cause of the dryness of the Dahomey Gap can simply be explained thus:
The Dahomey Gap has only existed in its present form for about four thousand years. For most of the Quaternary, dry conditions due to a much colder Atlantic Ocean (aided by extensive cold currents from ice sheets in Europe and North America) have meant that the present-day forest zone has supported very little or no rainforest. Overview The term Quaternary ("fourth" was proposed by Giovanni Arduino in 1759 for alluvial deposits in the Po river valley in northern In interglacial periods, however, rainfall throughout West Africa has often been so heavy that the Gap has become wet enough to support rainforest, thus eliminating the savanna. An interglacial is a geological interval of warmer global average temperature that separates Glacial periods within an Ice age.
