Kinshasa, formerly named Léopoldville until 30 June 1966, is the capital and largest city of the Democratic Republic of the Congo. Once a site of fishing and trading villages along the Congo River, Kinshasa is now one of the world's fastest-growing megacities. Kinshasa's 2024 population was estimated at 17,032,322. It is the most densely populated city in the DRC, the most populous city in Africa, the world's fourth-most-populous capital city, Africa's third-largest metropolitan area, and the leading economic, political, and cultural center of the DRC. Kinshasa houses several industries, including manufacturing, telecommunications, banking, and entertainment. The city also hosts some of DRC's significant institutional buildings, such as the Palais du Peuple, Palais de la Nation, Court of Cassation, Constitutional Court, Cité de l'Union Africaine, Palais de Marbre, Stade des Martyrs, Immeuble du Gouvernement, Kinshasa Financial Center, and multiple federal departments and agencies.
A flood is an overflow of water that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding. Examples for human changes are land use changes such as deforestation and removal of wetlands, changes in waterway course or flood controls such as with levees. Global environmental issues also influence causes of floods, namely climate change which causes an intensification of the water cycle and sea level rise. For example, climate change makes extreme weather events more frequent and stronger. This leads to more intense floods and increased flood risk.
Cesspit, cesspool and soak pit in some contexts are terms with various meanings: they are used to describe either an underground holding tank or a soak pit. A cesspit can be used for the temporary collection and storage of feces, excreta, or fecal sludge as part of an on-site sanitation system and has some similarities with septic tanks or with soak pits. Traditionally, it was a deep cylindrical chamber dug into the ground, having approximate dimensions of 1 metre (3') diameter and 2–3 metres depth. Its appearance was similar to that of a hand-dug water well.
Mont Ngafula, or Mont-Ngafula, is a commune in the Lukunga District of Kinshasa, in the western part of the Democratic Republic of the Congo. By its surface area, Mont Ngafula is the third-largest commune in Kinshasa's city-province. It is located in the hilly southern area of Kinshasa and is intersected by the Lukaya River valley in its southern portion. The boundary with the Ngaliema commune is defined by the Lukunga River. Mont Ngafula shares borders with the Makala commune to the north, the Kongo Central Province to the south, the Lemba and Kisenso communes to the east, and the Selembao commune to the west. It has an estimated population of 718,197 (2015).
Bandalungwa is a commune in the Funa District of Kinshasa in the western region of the Democratic Republic of the Congo. Covering an area of 6.82 square kilometers, Bandalungwa is centrally situated within the city. It is bordered by the Gombe commune and the Kokolo military barracks to the north, Selembao to the south, the communes of Ngiri-Ngiri, Kasa-Vubu, and Lingwala to the east, and the Makelele River, Ngaliema, and Kintambo to the west. The commune had an estimated population of 934,821 in 2015, although official census data from 2016 reported a significantly lower figure of 259,760 residents.
Barumbu is a commune in the Lukunga District of Kinshasa, located strategically in the northern region of the city. As of 2015, Barumbu had an estimated population of 413,628, making it one of Kinshasa's more densely populated communes.
Environmental issues in Haiti include a historical deforestation problem, overpopulation, a lack of sanitation, natural disasters, and food insecurity. The major reasons for these environmental issues are corruption, human exploitation, and the embezzlement of taxpayers' funds for personal gains. In addition, there is not sufficient protection or management of the country's natural resources. Other environmental issues, such as decreases in precipitation and more severe natural disasters, will likely arise in Haiti as a result of climate change. Experts agree that Haiti needs to adopt new policies to address both the issues that already exist and to prepare for the effects of climate change.
Sustainable drainage systems are a collection of water management practices that aim to align modern drainage systems with natural water processes and are part of a larger green infrastructure strategy. SuDS efforts make urban drainage systems more compatible with components of the natural water cycle such as storm surge overflows, soil percolation, and bio-filtration. These efforts hope to mitigate the effect human development has had or may have on the natural water cycle, particularly surface runoff and water pollution trends.
Selembao is one of the 24 communes that are the administrative divisions of Kinshasa, the capital city of the Democratic Republic of the Congo. Covering over 12 square kilometers and with an estimated population of 1,038,819 as of 2015, it is bordered to the north by the communes of Bandalungwa and Bumbu, to the northeast by Bumbu, to the south by Mont Ngafula, to the east by Makala, and to the west by Ngaliema.
Ngaba is a commune located in the Mont Amba District of Kinshasa, the capital city of the Democratic Republic of the Congo. It spans an area of 4.0 square kilometers and has an estimated population of 539,135 as of 2015.
Greater Mexico City, a metropolitan area with more than 19 million inhabitants including Mexico's capital with about 9 million inhabitants, faces tremendous water challenges. These include groundwater overexploitation, land subsidence, the risk of major flooding, the impacts of increasing urbanization, poor water quality, inefficient water use, a low share of wastewater treatment, health concerns about the reuse of wastewater in agriculture, and limited cost recovery. Overcoming these challenges is complicated by fragmented responsibilities for water management in Greater Mexico City:
Water resources management in Nicaragua is carried out by the National water utility and regulated by the Nicaraguan Institute of water. Nicaragua has ample water supplies in rivers, groundwater, lagoons, and significant rainfall. Distribution of rainfall is uneven though with more rain falling on an annual basis in the Caribbean lowlands and much lower amounts falling in the inland areas. Significant water resources management challenges include contaminated surface water from untreated domestic and industrial wastewater, and poor overall management of the available water resources.
Guatemala faces substantial resource and institutional challenges in successfully managing its national water resources. Deforestation is increasing as the global demand for timber exerts pressure on the forests of Guatemala. Soil erosion, runoff, and sedimentation of surface water is a result of deforestation from development of urban centers, agriculture needs, and conflicting land and water use planning. Sectors within industry are also growing and the prevalence of untreated effluents entering waterways and aquifers has grown alongside.
Water resources management in Belize is carried out by the Water and Sewerage Authority (WASA) in most cases. One of the primary challenges the country is facing with regard to water resources management, however, is the lack of coordinated and comprehensive policies and institutions. Furthermore, there are various areas of water management that are not well addressed at all such as groundwater data and provision of supply. Data on irrigation and drainage is not adequately available either. Demand on water resources is growing as the population increases, new economic opportunities are created, and the agriculture sector expands. This increased demand is placing new threats on the quality and quantity of freshwater resources. Other constant challenge for management entities are the constant threat of floods from tropical storms and hurricanes. The Belize National Emergency Management Organization (NEMO) is charged with flood management as they occur but it is unclear what institution has responsibility for stormwater infrastructures.
The Ndjili River is a river that flows from the south through the capital city of Kinshasa in the Democratic Republic of the Congo, where it joins the Congo River. It separates the districts of Tshangu and Mont Amba. The river gives its name to the Ndjili commune and to the Ndjili International Airport.
Funa is an area of the capital city of Kinshasa, Democratic Republic of the Congo, comprising seven of the city-province's twenty-four administrative divisions—the communes of Bandalungwa, Bumbu, Kalamu, Kasa-Vubu, Makala, Ngiri-Ngiri and Selembao. It is one of the four so-called districts of Kinshasa, which were the administrative divisions of the city during much of the Mobutu years (1965-1997) and around which a number of government systems and services are still organized. For instance, Funa makes up a twelve-member National Assembly constituency designated as Kinshasa II. However, these districts are not part of Congo's territorial organization.
Although the Democratic Republic of the Congo (DRC) has Africa's largest freshwater resources, it is suffering from an acute drinking water supply crisis. The DRC has one of the lowest rates of access to clean drinking water in Sub-Saharan Africa and the world. Only 46 percent of the population had access to an improved drinking water source in 2012. Furthermore, the sanitation coverage was estimated at only 31 percent in 2012. Up to date and accurate information on water supply and sanitation services in the DRC is scarce. As a result of inadequate water supply and sanitation services, many inhabitants are suffering from waterborne diseases, including diarrhoea, typhoid, and cholera.
Urban flooding is the inundation of land or property in cities or other built environment, caused by rainfall or coastal storm surges overwhelming the capacity of drainage systems, such as storm sewers. Urban flooding can occur regardless of whether or not affected communities are located within designated floodplains or near any body of water. It is triggered for example by an overflow of rivers and lakes, flash flooding or snowmelt. During the flood, stormwater or water released from damaged water mains may accumulate on property and in public rights-of-way. It can seep through building walls and floors, or backup into buildings through sewer pipes, cellars, toilets and sinks.
Corso Valley is a river that originates in the Khachna Mountains that flows through the Kabylie region, and ends in the Mediterranean Sea though the east of the town of Corso. The watercourse passes through Boumerdès Province along its route.
The Matete Market, also known as Matete Municipal Market, is a marketplace located in Matete, Kinshasa. Situated in the southern part of the city on a marshy alluvial plain, it is the third-largest market in Kinshasa and a vital economic center for the surrounding area. The market features a diverse range of sales facilities, categorized into four types based on their level of equipment and the income levels of the businesses operating within them. These include enclosed shops and store, semi-open pavilions supported by structural posts, vendor tables, and rudimentary open-air setups at ground level.
