U.S. Department of State Background Note
Algeria, the second-largest state in Africa, has a Mediterranean coastline of about 998 kilometers (620 mi.). The Tellian and Saharan Atlas mountain ranges cross the country from east to west, dividing it into three zones. Between the northern zone, Tellian Atlas, and the Mediterranean is a narrow, fertile coastal plain--the Tell (Arabic for hill)--with a moderate climate year round and rainfall adequate for agriculture. A high plateau region, averaging 914 meters (3,000 ft.) above sea level, with limited rainfall, great rocky plains, and desert, lies between the two mountain ranges. It is generally barren except for scattered clumps of trees and intermittent bush and pastureland. The third and largest zone, south of the Saharan Atlas mountain range, is mostly desert. About 80% of the country is desert, steppes, wasteland, and mountains. Algeria"s weather varies considerably from season to season and from one geographical location to another. In the north, the summers are usually hot with little rainfall. Winter rains begin in the north in October. Frost and snow are rare, except on the highest slopes of the Tellian Atlas Mountains. Dust and sandstorms occur most frequently between February and May.
Soil erosion--from overgrazing, other poor farming practices, and desertification--and the dumping of raw sewage, petroleum refining wastes, and other industrial effluents are leading to the pollution of rivers and coastal waters. The Mediterranean Sea, in particular, is becoming polluted from oil wastes, soil erosion, and fertilizer runoff. There are inadequate supplies of potable water.
Ninety-one percent of the Algerian population lives along the Mediterranean coast on 12% of the country"s total land mass. Forty-five percent of the population is urban, and urbanization continues, despite government efforts to discourage migration to the cities. About 1.5 million nomads and semi-settled Bedouin still live in the Saharan area.
Nearly all Algerians are Muslim, of Arab,
