Hadejia-Nguru Wetlands
300px, Yobe River catchment area showing location of the Hadejia-Nguru wetlands The Hadejia-Nguru wetlands in Yobe State in northern Nigeria, which include Nguru Lake, are ecologically and economically important. They are threatened by reduced rainfall in recent years, a growing population and upstream dam construction. Geography The wetlands lie in the Yobe-Komadugu sub-basin of the Chad Basin. They are formed where the Hadejia and Jama'are rivers meet lines of ancient sand dunes in a northeast–southwest alignment and break into numerous channels. They are drained by the Yobe River, which flows east towards Lake Chad. They lie between Sudanian Savanna to the south and the drier Sahel to the north. Some of the land is permanently flooded, while other parts are flooded only in the wet season (August and September). Annual rainfall ranges between 200 and 600 mm, during the period late May–September. At one time the wetlands may have covered up to 3,000 km2. Between ...

Dams In Nigeria
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. Ancient dams were built in Mesopotamia and the Middle East for water control. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. Egyptians also built dams, ...

Lake Chad Basin
The Chad Basin is the largest endorheic basin in Africa, centered approximately on Lake Chad. It has no outlet to the sea and contains large areas of semi-arid desert and savanna. The drainage basin is approximately coterminous with the sedimentary basin of the same name, but extends further to the northeast and east. The basin spans four modern nations, including most of Chad and a large part of Niger, Nigeria and Cameroon. A combination of dams, increased irrigation, climate change, and reduced rainfall are causing water shortages. Lake Chad continues to shrink. Geology The geological basin, which is smaller than the drainage basin, is a Phanerozoic sedimentary basin formed during the plate divergence that opened the South Atlantic Ocean. The basin lies between the West African Craton and Congo Craton, and formed about the same time as the Benue Trough. It covers an area of about . It merges into the Iullemmeden Basin to the west at the Damergou gap between the Aïr and Zin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Chad
Lake Chad (, Kanuri language, Kanuri: ''Sádǝ'', ) is an endorheic freshwater lake located at the junction of four countries: Nigeria, Niger, Chad, and Cameroon, in western and central Africa respectively, with a catchment area in excess of . It is an important wetland ecosystem in West-Central Africa. The lakeside is rich in reeds and swamps, and the plain along the lake is fertile, making it an important irrigated agricultural area. The lake is rich in aquatic resources and is one of the important freshwater fish producing areas in Africa. Lake Chad is divided into deeper southern parts and shallower northern parts. The water source of the lake mainly comes from rivers such as the Chari River that enter the lake. The water level varies greatly seasonally, and the area of the lake also changes dramatically. During the African humid period, the lake's area reached . Due to the increasingly arid climate, the lake surface gradually shrank. In the 19th century, it still had an are ...

Yobe River
The Yobe River, also known as the Komadougou Yobe also spelt Komadugu Yobe River or the Komadougou-Yobe (), is a river in West Africa that flows into Lake Chad through Nigeria and Niger. Its tributaries include the Hadejia River, the Jama'are River, and the Komadugu Gana River. The river forms a small part of the international border between Niger and Nigeria with 95 miles (150 km) and flows a total of 200 miles (320 km) There are concerns about changes in the river flow, economy and ecology due to upstream dams, the largest at present being the Tiga Dam in Kano State, with plans being discussed for the Kafin Zaki Dam in Bauchi State. The River Yobe provides a means of subsistence for hundreds of thousands of people who work in a variety of commercial and agricultural endeavours along its almost 200 km length in the state's northern region, which spans seven local government areas (LGAs) from Nguru to Yunusari.

Kafin Zaki Dam
The Kafin Zaki Dam is a controversial project to build a reservoir on the Jama'are River (also called the Bunga River in its upper reaches) in Bauchi State in the Northeast of Nigeria. Proposed dam and reservoir The proposed dam would be of zoned earthfill construction and would be 11 kilometres-long. It would be designed with the potential to install a 15 MW hydroelectric plant. The reservoir would have a storage capacity of 2,700 million cubic meters, and would be the second largest in Nigeria after the Kainji Dam. It would irrigate 120,000 hectares of arable land on which cash crops could be grown. Potentially the project would support production of one million tonnes of sugarcane annually and provide over one million jobs in industries related to agriculture. Project history The dam was first considered after the 1972-1974 drought in the Sahel, and during the Shehu Shagari regime in 1979-1982, a contract was awarded to Julius Berger Nigeria to build the dam. In 1984, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fulani
The Fula, Fulani, or Fulɓe people are an ethnic group in Sahara, Sahel and West Africa, widely dispersed across the region. Inhabiting many countries, they live mainly in West Africa and northern parts of Central Africa, South Sudan, Darfur, and regions near the Red Sea coast in Sudan. The approximate number of Fula people is unknown, due to clashing definitions regarding Fula ethnicity. Various estimates put the figure between 25 and 40 million people worldwide. A significant proportion of the Fula – a third, or an estimated 7 to 10 million – are pastoralists, and their ethnic group has the largest nomadic pastoral community in the world., Quote: The Fulani form the largest pastoral nomadic group in the world. The Bororo'en are noted for the size of their cattle herds. In addition to fully nomadic groups, however, there are also semisedentary Fulani – Fulbe Laddi – who also farm, although they argue that they do so out of necessity, not choice.
