Article Outline
Zambia, republic in south central Africa, bounded on the north by the Democratic Republic of the Congo (DRC, formerly Zaire) and Tanzania; on the east by Malawi; on the southeast by Mozambique; on the south by Zimbabwe, Botswana, and the Caprivi Strip of Namibia; and on the west by Angola. The area is 752,614 sq km (290,586 sq mi). Zambia’s capital and largest city is Lusaka.
Most of Zambia is high plateau with a flat or gently undulating terrain. Elevations average between about 1,100 and 1,400 m (about 3,500 and 4,500 ft). Mountains in the northeast exceed 2,000 m (6,600 ft). Major rivers are the Zambezi in the west and south and its tributaries, the Kafue in the west and the Luangwa in the east; and the Luapula and Chambeshi, in the north. Lake Bangweulu, in the north, is surrounded by a vast swampy region. Lake Kariba is a large reservoir formed by Kariba Dam on the Zambezi River.
Although lying within the Tropic Zone, much of Zambia enjoys a pleasant subtropical climate because of the high altitude. The average temperature in Lusaka during July, the coldest month of the year, is 16°C (61°F); the hottest month, January, has an average temperature of 21°C (70°F). Annual rainfall ranges from 750 mm (30 in) in the south to 1,300 mm (51 in) in the north. Nearly all of the rain falls between November and April.
Most of the country has savanna-type vegetation—grasslands interspersed with trees. Teak forests are in the southwest. Animals include elephants, lions, rhinoceroses, and several varieties of antelope. Of overwhelming importance are the rich mineral veins of the country’s copper belt. The belt extends down into Zambia from southern DRC and contains major deposits of copper, cobalt, and other minerals. Zambia also has substantial hydroelectric potential. The Kariba Dam on the Zambezi River is the country’s main power source. Zambia shares the Kariba system with Zimbabwe. Other stations on the Lunsemfwa and Mulungushi rivers serve Kabwe. Installations have also been built on the Kafue River. In 2003 the total output of electricity was 8.3 billion kilowatt-hours, nearly all of which was produced by hydroelectric plants.
