Kenya a country in East Africa famed for its scenic landscapes and vast wildlife preserves. Its Indian Ocean coast provided historically important ports by which goods from Arabian and Asian traders have entered the continent for many centuries.
Along that coast, which holds some of the finest beaches in Africa, are predominantly Muslim Swahili cities such as Mombasa, a historic center that has contributed much to the musical and culinary heritage of the country.
Inland are populous highlands famed for both their tea plantations, an economic staple during the British colonial era, and their variety of animal species, including lions, elephants, cheetahs, rhinoceroses, and hippopotamuses. Kenya’s western provinces, marked by lakes and rivers, are forested, while a small portion of the north is desert and semidesert.
The capital of Kenya is Nairobi, a sprawling city that, like many other African metropolises. Bisected horizontally by the Equator and vertically by longitude 38° E, Kenya is bordered to the north by South Sudan and Ethiopia, to the east by Somalia and the Indian Ocean, to the south by Tanzania, and to the west by Lake Victoria and Uganda.
The 38th meridian divides Kenya into two halves of striking contrast. While the eastern half slopes gently to the coral-backed seashore, the western portion rises more abruptly through a series of hills and plateaus to the Eastern Rift Valley, known in Kenya as the Central Rift. West of the Rift is a westward-sloping plateau, the lowest part of which is occupied by Lake Victoria. Within this basic framework, Kenya is divided into the following geographic regions: the Lake Victoria basin, the Rift Valley and associated highlands, the eastern plateau forelands, the semiarid and arid areas of the north and south, and the coast.
The Lake Victoria basin is part of a plateau rising eastward from the lakeshore to the Rift highlands. The lower part, forming the lake basin proper, is itself a plateau area lying between 3,000 and 4,000 feet (900 and 1,200 meters) above sea level. The rolling grassland of this plateau is cut almost in half by the Kano Plain, into which an arm of the lake known as Winam Gulf (Kavirondo Gulf) extends eastward for 50 miles (80 km). The floor of the Kano Plain merges north and south into highlands characterized by a number of extinct volcanoes. These include Mount Elgon, rising to 14,178 feet (4,321 meters) at the Ugandan border on the extreme north of the basin.
The Rift Valley splits the highland region into two sections: the Mau Escarpment to the west and the Aberdare Range to the east. The valley itself is 30 to 80 miles (50 to 130 km) wide, and its floor rises from about 1,500 feet (450 meters) in the north around Lake Turkana (Lake Rudolf) to over 7,000 feet (2,100 meters) at Lake Naivasha but then drops to 2,000 feet (600 meters) at the Tanzanian border in the south. The floor of the Rift is occupied by a chain of shallow lakes separated by extinct volcanoes. Lake Naivasha is the largest of these; the others include Lakes Magadi, Nakuru, Bogoria, and Baringo. West of the valley the diverse highland area runs from the thick lava block of the Mau Escarpment–Mount Tinderet complex northward to the Uasin Gishu Plateau. East of the Rift the Aberdare Range rises to nearly 10,000 feet (3,000 metres). The eastern highlands extend from the Ngong Hills and the uplands bordering Tanzania northward to the Laikipia Escarpment. Farther east they are linked by the Nyeri saddle to Mount Kenya, the country’s highest peak, at 17,058 feet (5,199 meters). The relief of both highlands is complex and includes plains, deep valleys, and mountains. Important in the historic and economic development of Kenya, the region was the focus of European settlement.
The eastern plateau forelands, located just east of the Rift highlands, constitute a vast plateau of ancient rocks gently sloping to the coastal plain. They are a region of scattered hills and striking elevated formations, the most prominent being the hills of Taita, Kasigau, Machakos, and Kitui. These hills, containing the area of more favorable climate, are surrounded by regions historically prone to famine.
The semiarid and arid areas in the north and northeast are part of a vast region extending from the Ugandan border through Lake Rudolf to the plateau area between the Ethiopian and Kenyan highlands. (The area from Lake Magadi southward, though not as arid, has the same characteristics.) Although tree and grass cover is scanty there, the areas of the true desert are limited to the Chalbi Desert east of Lake Rudolf. The movement of people and livestock is strictly limited by the availability of water.
The coastal plain proper, which runs for about 250 miles (400 km) along the Indian Ocean, is a narrow strip only about 10 miles (16 km) wide in the south, but in the Tana River lowlands to the north, it broadens to about 100 miles (160 km). Farther northeast it merges into the lowlands of Somalia. The excellent natural harbors include that of Mombasa, which is one of the best in East Africa.
