The Democratic Republic of the Congo (DRC) is the largest country of sub-Saharan Africa, occupying some 2,344,858 square kilometres (905,355 sq mi). Most of the country lies within the vast hollow of the Congo River basin. The vast, low-lying central area is a plateau-shaped basin sloping toward the west, covered by tropical rainforest and criss-crossed by rivers. The forest center is surrounded by mountainous terraces in the west, plateaus merging into savannas in the south and southwest. Dense grasslands extend beyond the Congo River in the north. High mountains of the Ruwenzori Range (some above 5,000 m or 16,000 ft) are found on the eastern borders with Rwanda and Uganda (see Albertine Rift montane forests for a description of this area).

Geographic regions

Several major geographic regions may be defined in terms of terrain and patterns of natural vegetation, namely the central Congo Basin, the uplands north and south of the basin, and the eastern highlands.

The country's core region is the central Congo Basin. Having an average elevation of about 44 metres (144 ft), it measures roughly 800,000 square kilometres (310,000 sq mi), constituting about a third of the DRC's territory. Much of the forest within the basin is swamp, and still more of it consists of a mixture of marshes and firm land.

North and south of the basin lie higher plains and, occasionally, hills covered with varying mixtures of savanna grasses and woodlands. The southern uplands region, like the basin, constitutes about a third of the DRC's territory. The area slopes from south to north, starting at about 1,000 metres (3,300 ft) near the Angolan border and falling to about 500 metres (1,600 ft) near the basin. Vegetation cover in the southern uplands territory is more varied than that of the northern uplands. In some areas, woodland is dominant; in others, savanna grasses predominate. South of the basin, along the streams flowing into the Kasai River are extensive gallery forests. In the far southeast, most of the former Katanga Province is characterized by somewhat higher plateaus and low mountains. The westernmost section of the DRC, a partly forested panhandle reaching the Atlantic Ocean, is an extension of the southern uplands that drops sharply to a very narrow shore about 40 kilometres (25 mi) long.

In the much narrower northern uplands, the cover is largely savanna, and woodlands are rarer. The average elevation of this region is about 600 metres (2,000 ft), but it rises as high as 900 metres (3,000 ft) where it meets the western edge of the eastern highlands.

The eastern highlands region is the highest and most rugged portion of the country. It extends for more than 1,500 kilometres (930 mi) from above Lake Albert to the country's southern tip and varies in width from 80 to 560 kilometres (50 to 348 mi). Its hills and mountains range in altitude from about 1,000 metres (3,300 ft) to more than 5,000 metres (16,000 ft). The western arm of the Great Rift Valley forms a natural eastern boundary to this region. The eastern border of the DRC extends through the valley and its system of lakes, which are separated from each other by plains situated between high mountain ranges.

In this region, changes in elevation bring marked changes in vegetation, which ranges from montane savanna to heavy montane forest. The Rwenzori Mountains between lakes Albert and Edward constitutes the highest range in Africa. The height and location of these mountains on the equator make for a varied and spectacular flora.

Rivers and lakes

Relief map of the DRC

The Congo River and its tributaries drain this basin and provide the country with the most extensive network of navigable waterways in Africa. Ten kilometres (6 miles) wide at the mid-point of its length, the river carries a volume of water that is second only to the Amazon's. Its flow is unusually regular because it is fed by rivers and streams from both sides of the equator; the complementary alternation of rainy and dry seasons on each side of the equator guarantees a regular supply of water for the main channel. At points where navigation is blocked by rapids and waterfalls, the sudden descent of the river creates a hydroelectric potential greater than that found in any other river system on earth.

Most of the DRC is served by the Congo River system, a fact that has facilitated both trade and outside penetration. Its network of waterways is dense and evenly distributed through the country, with three exceptions: northeastern Mayombe in Kongo Central in the west, which is drained by a small coastal river called the Shilango; a strip of land on the eastern border adjoining lakes Edward and Albert, which is part of the Nile River basin; and a small part of the extreme southeastern DRC, which lies in the Zambezi River basin and drains into the Indian Ocean.

Most of the DRC's lakes are also part of the Congo River basin. In the west are Lac Mai-Ndombe and Lac Tumba, which are remnants of a huge interior lake that once occupied the entire basin prior to the breach of the basin's edge by the Congo River and the subsequent drainage of the interior. In the southeast, Lake Mweru straddles the border with Zambia. On the eastern frontier, Lac Kivu, Central Africa's highest lake and a key tourist center, and Lake Tanganyika, just south of Lac Kivu, both feed into the Lualaba River, the name often given to the upper extension of the Congo River. Only the waters of the eastern frontier's northernmost great lakes, Edward and Albert, drain north, into the Nile Basin.

Climate

Democratic Republic of the Congo map of Köppen climate classification zones

Climate ranges from tropical rain forest in the Congo River basin to tropical wet-and-dry in the southern uplands to tropical highland in eastern areas above 2,000 metres (6,600 ft) in elevation. In general, temperatures and humidity are quite high. The highest and least variable temperatures are to be found in the equatorial forest, where daytime highs range between 30 and 35 °C (86 and 95 °F), and nighttime lows rarely go below 20 °C (68 °F). The average annual temperature is about 25 °C (77 °F). In the southern uplands, particularly in the far southeast Katanga region, winters are cool and dry, whereas summers are warm and damp. The area embracing the chain of lakes from Lake Albert to Lake Tanganyika in the eastern highlands has a moist climate and a narrow but not excessively warm temperature range. The mountain sections are cooler, but humidity increases with altitude until the saturation point is reached; a nearly constant falling mist prevails on some slopes, particularly in the Rwenzori Mountains.

The seasonal pattern of rainfall is affected by the DRC's straddling of the equator. In the third of the country that lies north of the equator, the dry season (roughly early November to late March) corresponds to the rainy season in the southern two-thirds. There is a great deal of variation, however, and a number of places on either side of the equator have two wet and two dry seasons. Rainfall averages range from about 1,000 to 2,000 millimetres (39 to 79 in). Annual rainfall is highest in the heart of the Congo River basin and in the highlands west of Bukavu and with some variation tends to diminish in direct relation to distance from these areas. The only areas marked by long four-month to five-month dry seasons and occasional droughts are parts of the Southeast.

Natural hazards:

periodic droughts in south; Congo River floods (seasonal); in the east, in the Albertine Rift, there are active volcanoes

Environment

The endangered mountain gorilla, half of its population live in the DRC's Virunga National Park, making the park a critical habitat for these animals.

Current issues

Poaching threatens wildlife populations (for example, the painted hunting dog, Lycaon pictus, is now considered extirpated from the Congo due to human overpopulation and poaching); water pollution; deforestation (chiefly due to land conversion to agriculture by indigenous farmers); refugees responsible for significant deforestation, soil erosion, and wildlife poaching; mining of minerals (coltan — a mineral used in creating capacitors, diamonds, and gold) causing environmental damage

Geography:

D.R. Congo is one of six African states that straddles the equator; it's the largest African state that has the equator passing through it.
