River basins in Nigeria

River basins are areas drained by rivers and their tributaries. There are over eighty major rivers in Nigeria, such as the Niger and Benue.

River basins are important because they provide drinking water, food, habitat for animals and plants, fossil information about life on Earth before humans existed, transportation through canals and roads, recreation at beaches and along river banks, hydroelectric power to provide electricity that people use every day, erosion control of land through which water flows year-round rather than just during rainy seasons, flood control by assisting people in staying safe from flooding.

There are eleven River Basin Development Authorities in Nigeria charged with tasks such as constructing water supply facilities to provide clean drinking water to people who live near rivers so they do not have to spend hours each day walking many kilometers away to get water or spend lots of money each month buying bottled water.

River Basin Development Planning and Management is the process of determining which activities will be done most effectively in order to meet competing demands while maintaining river health, which could be single-purpose, dual-purpose, multipurpose, comprehensive, or integrated.

River basins in Nigeria are threatened by waste inputs, excessive water resource exploitation, and invasive weeds. To sustain the economic growth of the nation’s river basins, rivers need to be properly and sustainably developed.

River basins development authorities in Nigeria and their areas of operation

Anambra-Imo river basin

They operate in the whole of Anambra and Imo State, and they have their HQ in Owerri.

Benin-Owena river basin

They cover the whole of Benin, Delta, and Ondo State excluding those parts of Bendel State drained by Benin, Escravos, Forcados, and Ramos river creek systems. They have their headquarters in Benin.

Chad river basin authority

This covers the whole of Borno State excluding those parts drained by the Jama’are and Misau river systems but including those parts of Gongola (Adamawa and Taraba) State drained by Yedseram and Goma river systems. Their Headquarters is in Maiduguri.

Cross river basin authority

They cover the whole of Cross River State. And they have their headquarters in Calabar.

Hadejia-Jama’are river basin

They cover the whole of Kano State and those parts of Bauchi and Borno State drained by the Jama’are and Misau river system. Their headquarters is in Kano.

Lower Benue River basin

They operate in the whole of Benue and Plateau State and have their HQ in Benue state.

Niger Delta river basin authority

They cover the whole of River State and those parts of Delta State drained by Benin, Escravos, Forcados, and Ramos river creek systems. They have their HQ in Port Harcourt.

Ogun-Osun river basin

They operate in the whole of Oyo, Ogun, Osun, and Lagos State. Their headquarters is in Abeokuta.

Upper Benue river basin authority

They cover parts of Bauchi State drained by the Gongola River system. The whole of Gongola State excluding those parts drained by the Yedseram river system. Their Headquarters is in Yola.

Sokoto-Rima river basin

They operate in the whole of Sokoto State and Kastina State. Their HQ is in Sokoto.

River Basin development in Nigeria and their mandate

The River Basin Development Authorities (“the RBDAs” or “the Authorities”) were created to harness and develop the nation’s water resources. They are also known as river management agencies and are tasked with

  • promoting sustainable development of the basin.
  • Preventing environmental degradation
  • coordinating multiple users of a shared basin (interstate and international).
  • promoting the sustainable provision of water through irrigation for agriculture (as well as promoting excess use of water and water resources that can lead to environmental fragility and deterioration).
  • The goal of this project is to decentralize planning and management, making it adaptive.
  • The integration of environmental dimensions with other aspects of planning and management is also one of the reasons why it was set up.

The importance of river basins in Nigeria

Nigeria is blessed with numerous river basins, and they often provide numerous benefits to mankind. The significant river basins in Nigeria include:

provision of drinking water

groundwater recharge through seepage into the river system, and various recreational opportunities such as fishing and swimming.

food

River basins are major sources of fish food production in Nigeria. The creatures that come from these waters are fed to humans. Aquatic organisms such as macrophytes and algae can be a good source of nutrition for man.

Water hyacinth is indigenous to Brazil, and it has been used fresh for feeding pigs in South West Colombia, where it was substituted for 20% of commercial feed with no toxicology issues. Silage composed of water hyacinths can be used for ruminant diets with excellent results for acceptability and palatability.

Water hyacinth is high in protein, potassium, and calcium. Phytoplankton such as chlorella and spirulina are both superfoods, and food supplements made from chlorella and spirulina can be found in different supermarkets in Nigeria.

Habitat

River basins are habitats for many organisms that live in the river system, including fish, crayfish, macrophytes, and microalgae. Other animals can be found there too: aquatic birds, zooplankton, and other animals.

Accumulation of fossil information

The accumulation of fossil information is what makes river systems great fossil reserves. They aid chronological measurement because they allow us to view past events and inhabitation.

Transportation

Transportation is another reason why these places are important; they can be used as a means of transportation from one place to another. Recreation is yet another reason why these places are important; the water contained in them has been used for recreational purposes like the construction of beaches and resorts.

Hydroelectric power provision

This involves the construction of dams along waterfalls in rivers for the generation of electricity, such as the Kainji dam.

Construction

The soil found in and around a river basin is very useful for construction in Nigeria, and as such, is exploited at Onitsha, along the river Niger.

Erosion control

Rivers help to control erosion by collecting and storing inland water run-off from rainfall.

Oceanic recharge

Rivers flow into the oceans and help recharge the system. In Nigeria, more than three-quarters of the river basins drain into the Atlantic Ocean.

Pollution control

Companies and industries discharge waste into rivers that are used as endpoints for their waste discharge.
