Karroo

Karroo or Karoo (both: kər`, kä–), the semiarid plateaus of South Africa. The

Little Karroo, in Western Cape, is located N of the Langeberg and Outeniqua Ranges and extends c.200 mi (320 km) from east to west at an altitude of 1,000 to 2,000 ft (305–610 m). It is separated from the

Great Karroo, in Western Cape and Eastern Cape (c.300 mi/480 km long; alt. 2,000–3,000 ft/610–915 m), by the Swartberg Mts. The

Northern Karroo, in Northern Cape, North West and Free State, forms (with the high veld) the innermost and highest of South Africa's plateau regions. It extends north from the Great Karroo, bounded by Namaqualand on the west and the Komsberg and Roggeveld escarpments on the southwest, and merges with the high veld of Free State and Transvaal provinces. Up to 4,000 ft (1,219 m) high in Northern Cape province, it rises to c.6,000 ft (1,829 m) in the high veld of Transvaal. It forms the lower western half of the central escarpment. The Karroo, where irrigated, is very fertile. Livestock grazing is important there, and citrus fruits and grains are raised. The name is also applied to the low scrub vegetation found in semiarid regions and also to a system of rocks laid down over central and southern Africa during the late Paleozoic and early Mesozoic eras.
