An African region up close

你需要知道的

• Two ocean currents shape South Africa: the warm Agulhas current brings humid air to the east coast, and the cold Benguela current feeds rich fishing waters in the west.
• The narrow coastal plains rise steeply, so rivers are short and fast, with few natural harbours and no navigable routes inland.
• The Great Escarpment, highest in the Drakensberg at over 3,400 m, separates the coast from the high interior plateau.
• Most people and the biggest cities, Johannesburg and Pretoria, sit on the Highveld, while the Orange River supplies water for farming.
• Rainfall drops sharply westwards; the Karoo lies in a rain shadow and depends on groundwater for sheep farming.
