By late August 1998, forces of the ANC, RPA, and UPDF clashed with troops from FAC and the Zimbabwe Defence Forces (ZDF) for control of the capital.148 The ZDF employed heavy artillery to bombard densely populated areas, including Kimbanseke, Masina, Ndjili, and the Kingatoko village, which located near the Bas-Congo border.[74]149 These attacks resulted in the deaths of approximately 50 civilians and left 282 wounded during the night of 27 to 28 August, leading to mass displacement as residents fled to safer parts of the city, while the ZDF's indiscriminate use of heavy weapons struck hospitals, religious buildings, and other non-combatant infrastructure without differentiating between military and civilian targets.[74]150 In some instances, Congolese military authorities exacerbated civilian casualties by ordering residents to remain in their homes.[74]151 On 28 August, in Mont-Ngafula, FAC soldiers brutally murdered two Red Cross volunteers, one by crushing his skull, as they tried to rescue victims in Mitendi and Mbenseke, which left several others injured.[74]152 Rebel forces also targeted critical infrastructure, including the Inga hydroelectric power station in Bas-Congo, which was seized by ANC, RPA, and UPDF troops on 13 August 1998 and had its turbines stopped for three weeks, cutting electricity and water to Kinshasa and parts of Bas-Congo and severely disrupting hospitals.[74]153

Human rights abuses, crackdowns on Cabindan separatists, and Joseph Kabila's rise to power

Political opponents and civilians were subject to extrajudicial executions, torture, rape, and arbitrary detentions.[74]154 Between August 1998 and January 2001, approximately 50 incident reports were submitted to the United Nations Commission on Human Rights and its mechanisms, including the Working Groups on arbitrary detention and enforced disappearances, and the Special Rapporteurs on torture and extrajudicial killings.155 Members of opposition parties such as the UDPS and PALU were particularly targeted, often detained in notorious facilities including the Police d'intervention rapide (PIR), the Direction des renseignements généraux et services spéciaux (DRGS, also called Kin Mazière), IPKIN (ex-Circo), and Kokolo Military Camp.[74]156 A major crackdown happened on 28 October 2000, when President Kabila's security forces arrested at least 93 people, including 60 soldiers and 33 civilians from North Kivu, South Kivu, and Maniema, accused of plotting a coup d'état involving Anselme Masasu Nindaga, a founding AFDL member; some detainees were summarily executed or tortured to death, while others were imprisoned for over three years and only released following a government-issued general amnesty.157 In line with its military alliance with Angola, the Kinshasa government also targeted members of the Front for the Liberation of the Enclave of Cabinda (FLEC), a separatist movement seeking independence for the Angolan province of Cabinda, shutting down FLEC offices in Kinshasa between 1998 and 1999, arresting numerous Cabindan militants, many of whom were tortured, forcibly transferred to Angola, or remain missing.[74]158

After the assassination of President Laurent-Désiré Kabila on 16 January 2001, his son and successor, Joseph Kabila, was quickly installed as president and prioritized the de-escalation of armed conflict and the promotion of national reconciliation, particularly through the organization of the Inter-Congolese Dialogue (ICD), which brought together government representatives, rebel movements, opposition parties, and civil society in a comprehensive peace process.[75]159 In March 2001, the United Nations Mission in the Democratic Republic of Congo (MONUC) deployed personnel to key conflict zones to monitor compliance with the Lusaka Ceasefire Agreement, yet violence continued, particularly in North and South Kivu, where clashes involved groups such as the Mayi-Mayi militias, FDD, ALiR, and ANC.[75]160 The ICD officially opened on 25 February 2002 in Sun City, South Africa, and a preliminary power-sharing agreement was signed on 19 April 2002 between Joseph Kabila and Jean-Pierre Bemba, though it faced opposition from RCD-Goma and parties including the UDPS.[75]161 Progress continued with a major diplomatic breakthrough on 30 July 2002, when Rwanda and the DRC signed a peace accord in Pretoria corpus, agreeing that Rwanda would withdraw its troops in exchange for the disarmament and repatriation of Hutu militias such as the FDLR, followed by a similar agreement with Uganda in Luanda corpus on 6 September 2002 to withdraw Ugandan forces and stabilize Ituri Province.[75]162

By year's end, foreign troops from Rwanda, Uganda, Zimbabwe, Angola, and Namibia had begun withdrawing, a move that culminated in the Global and All-Inclusive Agreement in Pretoria on 17 December 2002, which established a transitional power-sharing government and integrated former belligerents into a unified national army.[75]163 Despite ongoing challenges, the process advanced with the ICD ratifying the agreement on 1 April 2003 in Sun City, along with a memorandum on transitional governance and armed group integration, and transitional institutions were formally inaugurated on 30 June 2003.[75]164 Nevertheless, President Kabila, who remained in power until 2019, faced persistent opposition in Kinshasa, with his controversial victory in the 2006 presidential election triggering widespread unrest that prompted the deployment of European Union forces to support MONUSCO in maintaining order,[76][77] and another unrest emerged in 2016 when the Independent National Electoral Commission announced a two-year delay in holding new presidential elections, a decision that ignited mass protests in September and December marked by street barricades, violent clashes, and a high civilian death toll.[77][78]165

Geography

Location

Kinshasa is strategically situated on the southern bank of the expansive Malebo Pool, which covers 9,965 square kilometers in a broad crescent shape over flat, low-lying terrain with an average elevation of about 300 meters.[79][80]166 It is bordered to the east by the provinces of Mai-Ndombe, Kwilu, and Kwango, to the south by Kongo Central, and to the north and west by the Congo River, which forms the natural boundary with the Republic of the Congo corpus.[81]167

The Congo River, Africa's second-longest river after the Nile, has the continent's highest discharge and serves as a critical transportation route across much of the Congo Basin, with river barges navigable between Kinshasa and Kisangani and along several tributaries.168 It is also a significant source of hydroelectric power, with the potential downstream of Kinshasa to generate electricity sufficient for roughly half of Africa's population.[82]169

Relief

Topographically, Kinshasa has a marshy, alluvial plain, with altitudes ranging from 275 to 300 meters, along with hilly terrain that elevates from 310 to 370 meters.[83][81][84]170 It has four principal features: the Malebo Pool, a large water body with islands and islets; the Kinshasa Plain, a highly urbanizable area prone to drainage problems; the terrace, a series of low ridges overlooking the plain; and the hills area, marked by deep valleys and cirque-shaped formations.[81]171

The Malebo Pool extends roughly 35 kilometers long and 25 kilometers wide, bordered by Ngaliema in the west and Maluku in the east, and passes through other communes including Gombe, Barumbu, Limete, Masina, and Nsele.[81]172 The Kinshasa Plain has a banana-like shape and is surrounded by eastward-oriented hills.173 Comprising mainly sandy alluvial deposits, this plain covers an area of about 20,000 hectares and hosts some of the city's most densely populated and urbanized communes,[81][85] such as Limete, Kalamu, Bandalungwa, Ngiri-Ngiri, Kinshasa, Barumbu, and Lingwala.174 Despite its urban potential, the plain is highly vulnerable to seasonal flooding and waterlogging due to inadequate drainage infrastructure, with recurrent inundation occurring during the rainy season.[85]175

The terrace is mainly situated in the city's western expanse, between N'djili and Mont-Ngafula.176 It comprises stony blocks of soft sandstone and silica-covered yellow clay, topped with brown silt, and ranges from 10 to 25 meters in height.177 It retains vestiges of an ancient surface.[81]178 The hills area commences several kilometers from the Malebo Pool and is characterized by deep valleys and cirque-shaped formations.179 These hills reach heights surpassing 700 meters and exhibit gentle, rounded contours sculpted by local rivers.[81]180 While their eastern counterparts may reflect remnants of the Batéké Plateau, their origins in the west and south remain enigmatic.[81]181 This region forms a natural amphitheater shaped by river erosion processes, which have been exacerbated by anthropogenic activities, often resulting in significant environmental degradation.[85]182 Communes located within or adjacent to these hilly areas include Mont-Ngafula, Bumbu, Selembao, Kisenso, and Ngaliema.183 In addition, Makala and Ngaba, although partially located within the plains, gradually ascend into the adjacent highlands.[85]184

Hydrography

Kinshasa's hydrographic landscape is defined by an intricate and predominantly dendritic network of rivers and valleys that converge toward Pool Malebo.185 This fluvial system, which predominantly flows from the southern and southwestern highlands toward the north and northeast, is shaped by the region's topographical gradient and its underlying lithological structure.[86]186 The city's current hydrological dynamics are the cumulative result of long-term tectonic shifts, sedimentary processes, and climatic variability that have defined the development of river systems over geological time scales.[86]187

The hydrographic system is composed of two main categories of rivers: allochthonous (originating outside the city) and autochthonous (local or internal to the city).188 The allochthonous rivers, which include the N'djili, N'sele, and the Pool Malebo, form the city's eastern and northern boundaries.[86]189 These rivers have their sources far beyond the city's southern hills and generally flow in a south-to-north direction.190 The N'djili River, in particular, is prone to recurrent seasonal flooding in its lower reaches, frequently disrupting critical infrastructure.[86]191 In contrast, the autochthonous rivers, such as the Funa, Lukunga, Bombo, Mai-Ndombe, and Mbale, are generated from localized watersheds scattered throughout the urban area.[86][81][87][88]192 These rivers often carve deeply incised valleys, especially in the elevated southern regions.193 The Funa River is commonly but inaccurately referred to as the Kalamu, a misnomer derived from the Teke-Humbu term for "watercourse".[86]194

Geomorphology

The current hydrographic network overlays an ancient system, likely dating back to the Tertiary period, which originally drained from south to north but was subsequently modified by tectonic deformation following the late Cretaceous peneplanation.195 These geodynamic changes reoriented some rivers east–west in the eastern parts of the Congo Basin and west–east in the west.[86]196 Traces of this paleonetwork persist in the form of broad, flat-bottomed valleys known as dambos or dembos, which emerged during the Holocene epoch.197 Characterized by diffuse channels and lacking pronounced riverbeds, these depressions often remain waterlogged throughout the year due to the persistent upwelling of the groundwater table.[86]198 In recent centuries, however, increased hydrological stress, marked by heightened peak runoff, has induced the incision of more distinct channels within these formerly marshy landscapes.[86]199 This hydrological transformation is evidenced by a marked rise in surface runoff and a reduction in infiltration retention, resulting in flashier hydrographs, more frequent flood events, and accelerated erosional processes.[86]200 Recent studies estimate Kinshasa's runoff coefficient has increased to approximately 13%, a stark contrast to the near-zero levels before urban expansion and land-use change.[86]201

Aquifers and water table

Closely connected to the surface drainage network are the city's groundwater systems, particularly the perched aquifers found in its permeable sandstone substratum.[86]202 These aquifers, often extending beyond the limits of their corresponding surface catchments, are sustained by deep percolation facilitated by the sandy and porous characteristics of the regional soils.[86]203 During the dry season, rivers are primarily fed by these underground aquifers, which are recharged during the rainy season.204 Early seasonal rains are absorbed into the soil and do not contribute to surface runoff until the retention threshold is surpassed, at which point excess water seeps downward to replenish groundwater reserves.[86]205 The region's high soil permeability also facilitates the formation of erosion cirques, particularly on steep slopes where groundwater undercutting and concentrated surface runoff progressively destabilize hillsides, often culminating in landslides.[86]206 These geomorphic hazards have become increasingly pronounced in the city's rapidly urbanizing fringe zones, where informal settlement expansion, deforestation, and inadequate land-use planning intensify environmental vulnerability.[86]207

Soil and geology

The city's soils predominantly belong to the Arenoferrasol classification,[89][90] characterized by fine-textured sands with clay content typically below 20%, low organic matter, and saturated absorbent complexes.[81]208 These soils has a strong acidity and are chemically deficient.[86]209 Despite their limited nutrient availability, they experience regular rainfall for approximately eight to nine months annually, resulting in significant leaching and intense hydrolysis of soil minerals.210 This extended exposure to precipitation adversely affects soil fertility and agricultural potential.[86]211

Geologically, Kinshasa is situated on a Precambrian basement complex, mainly composed of finely stratified red sandstone that often contains feldspar, visible at the base of the rapids near Mount Ngaliema and south of the N'djili River, where the rock shows strong resistance to erosion.[81]212

The soil is shaped by these geological variations: schisto-limestone formations, along with older lithologies associated with the West-Congolian Orogeny, generate yellow, clay-rich soils that are largely sterile and exhibit low permeability proportional to their sand content, while schist-sandstone and clay-limestone substrata produce yellow to light brown clayey sands with slightly better permeability but minimal fertility.[86]213 Fertile soils are primarily located within alluvial and colluvial deposits, where sediment accumulation enhances nutrient content and moisture retention.[86]214

In elevated terrains and along the slopes of deeply incised valleys, hydric erosion actively reshapes the schist-sandstone relief and ancient massifs.215 In these areas, soils are predominantly grayish sandy or clay-sandy in texture.[86]216 In lower-lying regions, a distinctive local material known as Lemba sand is prevalent, although certain pockets of clay-sandy soils yield improved crop outcomes.[86]217
