Nkéni-Alima Department
From Wikipedia, the free encyclopedia
Nkéni-Alima borders the departments of Congo-Oubangui to the northeast, Cuvette to the north, Cuvette-Ouest to the northwest, and Plateaux Department to the south.[2] Its eastern border is the Congo River: on the other side of the river are the provinces of Maï-Ndombe and Équateur of the Democratic Republic of the Congo.
Nkéni-Alima is located in the central part of the Republic of Congo, on a forested plain extending north of the Batéké Plateau.[3] Lying in the Northwest Congolian lowland forests ecoregion,[4] the department features a mosaic of gallery and swamp forests.[5]
The eastern part of the department between the Alima and Ntsakosso rivers is designated as part of the Grands Affluents Ramsar site, which was grouped with Lake Tele in Likouala Department and Ngiri-Tumba-Maindombe in the Democratic Republic of the Congo as a transboundary Ramsar site in 2017, the largest such site in the world.[6][7]
Nkéni-Alima experiences a tropical savanna climate with an average temperature of around 25 °C (77 °F). Annual rainfall ranges from 1,600 to 2,200 mm (63 to 87 in), and the dry season lasts about three to four months between June and September.[3][5]
History
The Teke people are believed to be the first inhabitants of the region, establishing an independent principality at Etan, now Mbaya in Gamboma District. In the 15th century, the Bobangi and Mbochi peoples entered the area from the east, fleeing conflicts with the Fang.[3]
Ethnic conflicts in the Democratic Republic of the Congo continue to cause displacement of refugees into the area such as at Makotimpoko and Gamboma, most recently in December 2018[8] and February 2025.[9]
On 8 October 2024, Congo's National Assembly approved the creation of three new departments: Congo-Oubangui, Djoué-Léfini, and Nkéni-Alima.[2]
Administration
Nkéni-Alima is divided into the six districts of Abala, Allembé, Gamboma, Makotimpoko, Ollombo, and Ongogni.[2] The districts of Abala, Gamboma, Ollombo and Ongogni each contain an urban community (communauté urbaine) of the same name.[10]
The first prefect of Nkéni-Alima is Alphonsine Akobé Opangana, who was appointed in April 2025.[11]
