Kalehe Territory is a territory in South Kivu, Democratic Republic of the Congo. Covering an area of 5,057 square kilometers, it is located northwest and northeast of the provincial capital, Bukavu, and has a population of 933,181 as of 2022. The territory is bordered by Idjwi Territory and Lake Kivu to the east, Shabunda Territory and the Irhambi-Katana groupement of Kabare Territory to the west, Mbinga-Nord groupement, Goma and Masisi Territory to the north, and Kabare Territory, and Maniema Province to the south.
Administratively, Kalehe Territory is divided into two chiefdoms: Buhavu and Buloho. Buhavu Chiefdom, situated along the shores of Lake Kivu, consists of seven groupements and is the most populous, primarily inhabited by the Havu people, along with the Tembo, Rongeronge, Banyarwanda communities. Buloho Chiefdom, traversed by National Road No. 3 linking Bukavu and Kisangani and passing through Kahuzi-Biéga National Park, comprises eight groupements and has a similar ethnic composition, with the Baloho clan of the Bashi people being the dominant ethnic group.
Geography
Location Kalehe Territory is located in the northern region of South Kivu Province, in the eastern Democratic Republic of the Congo, with its topography dominated by the Mitumba Mountains in the east. Positioned northwest and northeast of Bukavu, it is part of the "Mountainous Kivu" region, where the Mitumba Mountains form a natural divide between the lowlands of the East African Rift Valley. This area constitutes the middle section of the Great East African Rift, extending 1,400 km in length with an average width of 40 km. The rift valley is divided into three major zones, dominated by Lake Tanganyika in the south, Lake Kivu in the center, and Lake Edward in the north. Kalehe Territory is among the territories linked to the Lake Kivu basin, along with Masisi, Nyiragongo, Idjwi, Kabare, Walungu, Uvira, and Fizi territories. These areas are characterized by high-altitude landscapes ranging from 1,500 to 2,200 meters.
The territory shares its northern border with the city of Goma (through the Katiruzi Strait) and Masisi Territory, separated by the Chungiri River. from To the south, it borders Kabare Territory along the Nyawarongo River. Its eastern boundary is defined by Lake Kivu, which extends for more than 86 km from north to south, forming a significant tectonic fault. To the west, it borders Shabunda Territory, as well as parts of Idjwi Territory and Irhambi-Katana groupement of Kabare Territory. The eastern sector of Kahuzi-Biéga National Park, a UNESCO World Heritage Site, is partially located within Kalehe Territory and extends along its borders with Shabunda and Kabare.
Climate Kalehe Territory experiences a mountainous climate, with altitudes ranging from 1,300 to 2,000 meters. It has two distinct seasons: a long bimodal rainy season lasting nine months (September to May) and a short dry season of three months (June to August). Annual temperatures range between 18 °C and 22 °C, while precipitation varies from 1,300 to 1,680 mm per year. The highest peak in the territory is Mount Kahuzi, located in Buloho Chiefdom, rising to an altitude of 3,308 meters.
Geology, vegetation and hydrology
The soil is predominantly clayey and highly fertile, making it suitable for agriculture and livestock farming. The subsoil of Kalehe is rich in mineral resources, including gold, cassiterite, coltan, tungsten, quartz, muscovite, copper, and tourmaline.
The territory also experiences deep chemical weathering, which contributes to its high susceptibility to erosion and mass wasting. These include hypodermic water circulation (inferoflux), landslides, solifluxion, and terrain slippage. Watersheds such as Nyabarongo, Nyamukubi, and Ndindi exhibit clear signs of regressive erosion, a process that leads to the backward retreat of slopes, particularly in regions with torrential streams. The combination of intense vertical land dissection and steep mountain topography has carved out canyon-like valleys that eventually transform into broad, trough-shaped valleys with low downstream hydraulic gradients (less than 3°). These serve as sediment traps where materials transported from upstream settle, creating a rugged lakeshore landscape with exposed, partially weathered rocks.
The extent of weathering has also given rise to distinct sedimentary formations:
Sandy zones from the breakdown of metamorphic rocks, Clay-rich wetlands formed from the alteration of magmatic rocks.
These diverse zones support a range of ecosystems, including fish nurseries, marshlands, and beaches along Lake Kivu.
Fluvial, rainfall-induced, and surface runoff erosion have collectively rounded rocky ridges and given rise to the convex hill formations that typify Kalehe Territory's landscape. Kalehe Territory is particularly prone to erosion, a characteristic typical of equatorial highland regions. Rampant deforestation and inadequate land-use planning continue to exacerbate the situation, resulting in frequent landslides and severe flooding.
The vegetation is primarily composed of forests, including bamboo and shrubs, though deforestation due to agriculture, charcoal production, firewood collection, timber harvesting, and mining activities has led to significant environmental degradation. Scattered afforestation efforts exist across the territory.
Kalehe Territory is also rich in water resources, with 12 main rivers, in addition to Lake Kivu. The major rivers in the territory include Luhoho, Tchiganda, Mwabo, Nyamunene, Nyawaronga, Ndindi, Nyamasasa, Lwama, Eke, Kahoho, Luhaha, and Lua.
Administrative division
Historical background Kalehe Territory was officially established through General Administration Ordinance No. 10, which implemented the Decree of 28 March 1912 concerning the territorial organization of the Kivu District. Over time, its boundaries were modified by subsequent ordinances, including No. 91/AIMO of 23 April 1933, No. 70/AIMO of 25 March 1945, and Ordinance No. 21/423 of December 1950. The most significant territorial change occurred following Ordinance No. 68/18 of 12 January 1968, which led to the creation of Idjwi Territory in 1974.
Chiefdoms and governance The territory is structured into two chiefdoms, Buhavu and Buloho, each led by a customary chief, commonly referred to as the "mwami". The mwami, a direct descendant of the region's traditional rulers, is assisted by an Administrative Secretary and an Accounting Receiver, along with other sectoral service officials. Each chiefdom is subdivided into groupements (groupings), which are administered by groupement chiefs (chefs de groupement). These groupements are further divided into villages (localités), each under the leadership of a village chief. Although the mwami is chosen from the royal family in accordance with customary traditions, he remains subordinate to the territorial administrator, who holds the official hierarchical authority.
Buhavu Chiefdom consists of seven groupements:
Buloho Chiefdom includes eight groupements:
Security problems Interethnic and territorial disputes The territory is composed of two chiefdoms: Buhavu and Buloho, whose boundaries and authority have historically been contested. The Buhavu Chiefdom, which consists of seven groupements, is predominantly inhabited by the Bahavu people, who occupy Buzi, Mbinga-Nord, and Mbinga-Sud. The Batembo control Kalima, Mubuku, and Ziralo, while the Barongeronge reside in Kalonge. Disputes over land ownership and administrative authority have led to tensions between these groups.
A key source of conflict is the demand for autonomy by the Batembo and Barongeronge, who seek administrative independence from the Bahavu. The Batembo, in particular, have sought to reestablish their cultural and political unity, which was fragmented by colonial-era territorial divisions since 1945. However, this aspiration is strongly opposed by the Bahavu, who fear the loss of territory, resources, and economic influence.
The conflict between the Batembo and Bahavu escalated in 1999 with the occupation of the region by Rwanda and Uganda-backed rebel group Congolese Rally for Democracy (RCD), which was staunchly opposed to the central government in Kinshasa. Under RCD authority, the administrative restructuring of Kalehe Territory culminated in the provisional designation of Bunyakiri as an independent territorial entity, an action that was formally instituted through a departmental decree on 22 July 2002. Its internal subdivisions and boundaries with neighboring territories were defined by decrees dated 7 August and 28 September 2002. This reorganization resulted in the Bahavu losing significant territorial influence and access to mining sites. Beyond the indigenous interethnic rivalries, the Bahavu, Batembo, and Banyarwanda, comprising Batutsi and Bahutu, remain embroiled in long-standing disputes, particularly in the middle and high plateaus of Kalehe Territory. These disputes primarily center on nationality and land ownership. The Bahavu and Batembo have historically regarded the Banyarwanda as foreigners, arguing that their presence in the region dates back only to the migratory waves of 1959, thus denying them land rights and political representation. Banyarwanda presence in the territory dates back to colonial migration policies. In the 1950s, Hutu migrants arrived as part of Belgian efforts to provide labor for plantations in the then-Belgian Congo. Some of these migrants had initially settled in Masisi Territory, North Kivu, before relocating to Kalehe Territory. Customary Bahavu and Batembo chiefs granted them access to unoccupied land in the highlands (Hauts Plateaux). Subsequently, from 1959 onwards, political upheavals in Rwanda led to an influx of Tutsi refugees, who also settled in the territory and acquired land.
Over time, these migration patterns reshaped the territory's social structure, intensifying competition over land and resources. Disputes emerged between migrant Banyarwanda and indigenous communities as well as between Tutsi pastoralists, who required extensive grazing land, and Hutu agriculturalists, who prioritized farmland. During the early 1990s democratization process, Kalehe's land conflicts became increasingly politicized, with identity politics fueling tensions. The citizenship status of Congolese Tutsi became a highly contested issue, with various armed groups in eastern Congo mobilizing around the question of Rwandophone identity. These disputes escalated amid broader ethnic struggles in the region. The Banyarwanda, on the other hand, assert their Congolese identity, emphasizing that they have severed ties with Rwanda and are recognized under the Congolese Constitution of 18 February 2006. They demand administrative recognition, including the establishment of a chiefdom that reflects their presence and customary authority. These demands were reinforced during the RCD's control of the region when the movement established the Buzi highlands as a Banyarwanda-administered chiefdom, which further deepened the ethnic cleavages and hostility among local communities.
