Benue River (French: la Bénoué), previously known as the Chadda River or Tchadda, is a major tributary of the Niger River.[2] The size of its catchment basin is 319,000 km2 (123,000 sq mi). Almost its entire length of approximately 1,400 kilometres (870 mi) is navigable during the summer months.[3][1] As a result, it is an important transportation route in the regions through which it flows.[4] The name Benue comes from Binuwe, meaning 'Mother of Waters’ in the Batta language.[5]

At the point of confluence, the Benue exceeds the Niger by volume. The mean discharge before 1960 was 3,477 cubic metres per second (122,800 cu ft/s)[1] for the Benue and 2,863 cubic metres per second (101,100 cu ft/s) for the Niger.[1] During the following decades, the runoff of both rivers decreased markedly due to irrigation.[citation needed]
Climate
Benue State has a tropical savanna climate. It is warm every month of the year throughout both wet and dry seasons. The annual temperature is 34°C and there is about 244 inch of rain in a year.[7] The state has an average humidity of 61%, dew point of 25 °C, an UV-index of 7 and it is mainly dry for 169 days in a year.[8]
Major floods
Nigeria’s National Emergency Management Agency (NEMA), conducted a “disaster risk management analysis” and advised Ministries, Departments, and Agencies (MDAs) to take proactive steps to mitigate the impact of climate change. The agency advised that water bodies across some states be desilted and dredged regularly to make water available for various purposes. The agency urged relevant institutions to carry out routine monitoring of dams and water bodies to ensure their operation rule curve for reservoirs is adhered to.[9]
2022 Flood
On September 23, 2022, flooding affected all riverine local government areas of Benue, according to the state Commissioner for Water Resources and Environment, Godwin Oyiwona. The flooding affected Makurdi, Agatu, Logo, Guma, Buruku, Otukpo, and Gwer-West.[10] The government worked to mitigate flooding effects and released funds for cleaning the Idye Basin.[11]
In October 2022, farmers in Adamawa State struggled to clear off remnants of crops destroyed by the flooding. The disaster disrupted many communities across Nigeria’s 36 states, with hundreds of villages and urban centers submerged in water. The disaster unsettled over 2.4 million people and over 600 fatalities were recorded. Additionally, "expansive hectares of farmlands across affected states were swept off."[3]
The worst hit were mostly residents of agrarian communities near major tributaries in seven of the 21 local government areas in the state. Within three months, 12 Local Government Areas (LGAs) were submerged, affecting 82,730 residents, 13,788 households, 51 people injured, and 27 deaths. Farmlands worth billions of naira were destroyed.[citation needed]
January 2020
President Muhammadu Buhari inaugurated a 3.35-km drainage channel project in Makurdi, Benue, to address ecological challenges in the Idye Community.[12] The project, part of the 17 ecological intervention projects, was approved by the President in the fourth quarter of 2017 and completed in 48 weeks. The project aimed to address the devastating effects of erosion and flood in the region.[13][12]
2017 Flood
News Agency of Nigeria (NAN) reported that Idye Community was among the worst-hit areas of the 2017 flood that displaced over 120,000 persons[14] in the Benue capital, Makurdi. Floods devastated more than 200 households in Makurdi.[15]
Benue Hike Tourism and Conservation Foundation, in an attempt to keep the river protected from various forms of pollution, informed the Benue State Government about the irregularities of some companies in the state for emptying waste in the river. Waste like ethanol, that could easily cause damage to human and aquatic life, was dumped into Benue River. Subsequently, the Benue State Government took an immediate attempt in addressing the issue to prevent further damages for its citizenry.[19][20][21]
