Key: Cameroon Highlands are shown in western Cameroon near the Nigeria-Cameroon border; Fouta Djallon Highlands are shown in Guinea, West Africa. The River Niger, which rises in the Fouta Djallon Highlands, is also shown and named.
(b) Importance of rivers to the economy of Africa
- They provide inland waterways for transporting people and goods.
- They are dammed to generate hydro-electric power for homes and industries.
- They provide fish, which is a source of food, income and employment.
- They supply water for irrigation, thereby supporting crop production, especially during dry periods.
(c) Problems limiting the use of African rivers
- The presence of rapids, waterfalls and cataracts interrupts navigation and makes many river sections unsafe for boats.
- Seasonal fluctuations in water volume cause flooding in the wet season and very shallow channels in the dry season.
- Silting, sandbanks, floating vegetation and debris obstruct channels and ports, restricting the movement of vessels.
