Jabi Lake
Jabi Lake is a water body formed from a man-made earth dam that was initially created to provide water to the residents of Abuja, Nigeria. The total surface area of the lake is about . The initial capacity of the reservoir was to supply water to 100,000 residents. But after the construction of the bigger Lower Usuma Dam, the reservoir became a fishing and tourism attraction. Locality The environs of the lake has seen steady growth in land use Land use involves the management and modification of natural environment or wilderness into built environment such as settlements and semi-natural habitats such as arable fields, pastures, and managed woods. Land use by humans has a long h ... starting in the late 1980s. In 2007, an area surrounding the lake was named Jabi Lake Park and is planned to include a resort. Social events are held within the park and the lake provides activities for fun seekers such as boat rides. References {{reflist Abuja Reservoirs in Nigeria ...

Reservoir
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam A dam is a barrier that stops or restricts the flow of surface water or underground streams ...

Embankment Dam
An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core. This makes the dam impervious to surface or seepage erosion. Such a dam is composed of fragmented independent material particles. The friction and interaction of particles binds the particles together into a stable mass rather than by the use of a cementing substance. Types Embankment dams come in two types: the earth-filled dam (also called an earthen dam or terrain dam) made of compacted earth, and the rock-filled dam. A cross-section of an embankment dam shows a shape like a bank, or hill. Most have a central section or core composed of an impermeable material to stop water from seeping through the dam. The core can be of clay, concrete, or asphalt concrete. This type of dam is a good choice for sites wit ...

Abuja
Abuja () is the capital and eighth most populous city of Nigeria. Situated at the centre of the country within the Federal Capital Territory (FCT), it is a planned city built mainly in the 1980s based on a master plan by International Planning Associates (IPA), a consortium of three American planning and architecture firms made up of Wallace, Roberts, McHarg & Todd (WRMT – a group of architects) as the lead, Archisystems International (a subsidiary of the Howard Hughes Corporation), and Planning Research Corporation. The Central Business District of Abuja was designed by Japanese architect Kenzo Tange. It replaced Lagos, the country's most populous city, as the capital on 12 December 1991. Abuja's geography is defined by Aso Rock, a monolith left by water erosion. The Presidential Complex, National Assembly, Supreme Court and much of the city extend to the south of the rock. Zuma Rock, a monolith, lies just north of the city on the expressway to Kaduna. At the 2006 ce ...

Land Use
Land use involves the management and modification of natural environment or wilderness into built environment such as settlements and semi-natural habitats such as arable fields, pastures, and managed woods. Land use by humans has a long history, first emerging more than 10,000 years ago. It has been defined as "the purposes and activities through which people interact with land and terrestrial ecosystems" and as "the total of arrangements, activities, and inputs that people undertake in a certain land type." Land use is one of the most important drivers of global environmental change. History Human tribes since prehistory have segregated land into territories to control the use of land. Today, the total arable land is 10.7% of the land surface, with 1.3% being permanent cropland. Regulation Land use practices vary considerably across the world. The United Nations' Food and Agriculture Organization Water Development Division explains that "Land use concerns the produ ...
