Towns, Cities and Territories
Mai-Ndombe is one of the 26 provinces created in the 2015 repartitioning, formed by joining the old Mai-Ndombe and Plateaux districts of Bandundu. It has eight territories, each named after its headquarters town.
| Territory | Headquarters | Note |

Nioki, in Kutu territory, is the province’s busiest town and its main river port, ahead of the capital. Other places to know: Semendua and Bokoro in Kutu territory, Ntandembelo, Bosobe, and Ibali on the Lokoro. Most of the population lives in villages strung along the lake shore and the rivers rather than on roads.
Geography
Lake Mai-Ndombe sits at the province’s centre, covering roughly 2,300 km² and doubling or tripling in the rainy season. It is shallow — about 5 m on average, 10 m at most — and drains south by the Fimi River into the Kwa and then the Congo.
The province borders the Republic of the Congo to the west across the Congo River, Kinshasa to the south-west, Kwilu to the south, Kasai and Sankuru to the east, and Tshuapa and Equateur to the north. The south is savanna plateau; the north and east are rainforest and seasonally flooded swamp.
Demographics
Density is roughly 18 people per km², among the lowest in the country. All DR Congo population figures are projections — the last census was in 1984.
The Teke live in the south around Bolobo and Kwamouth, the Mongo and related groups in the northern forest, the Nunu and Sakata around the lake, and Twa communities in the forest interior. Lingala is the general language across the province, with Kiteke and Lomongo spoken locally. French is the official language.
Economy and Local Life
Fishing on Lake Mai-Ndombe and the rivers is the backbone of local income; smoked and salted fish goes downriver to Kinshasa. Cassava, maize, plantain and palm oil are the main crops, and Nioki has a long-running timber and plywood industry.
Industrial logging concessions cover a large share of the northern forest. Since 2011 the Mai Ndombe REDD+ project, run by Wildlife Works through its ERA Congo subsidiary, has held a conservation concession of about 300,000 hectares, selling forest-carbon credits and funding schools, clinics and wells in nearby villages. Nioki, Kutu and Inongo are the market towns everything passes through.
History
The area was part of Léopold II’s Congo Free State rubber system and later of Équateur, then of Bandundu province from 1966. Mai-Ndombe existed briefly as a province from 1962 to 1966. It was recreated on 18 July 2015 when Bandundu was split into Mai-Ndombe, Kwango and Kwilu, merging the Mai-Ndombe and Plateaux districts. The lake was known as Lake Leopold II until 1972.
Getting There
Water is the main way in. Boats and barges run from Kinshasa up the Congo and Kasai to Bolobo, Kwamouth, Mushie, Nioki and on across the lake to Inongo; the trip takes days, and overloaded passenger boats have caused repeated fatal accidents. Inongo and Nioki have airstrips with irregular flights. Roads exist between Kwamouth, Bolobo and Yumbi in the south but are poor and largely unusable in the rains.
