1.2 The African Continent: A Varied Landscape
Africa is the world's second-largest continent, with five main climate zones, five great rivers and coastlines on two oceans and two seas. These differences shaped where people settled, what they produced and how they traded with each other and the wider world.
Key terms
- Sahara
- Sahel
- savannah
- tropical rainforest
- Niger River
- Nile River
Five climate zones
Africa covers about one-fifth of the Earth's land, and it isn't one environment. Its climate zones are arranged in rough bands. Tropical rainforest lies near the equator, savannah grasslands sit on either side of it, then come semiarid lands and deserts, with a Mediterranean climate at the far northern coast and the southern tip.
| Zone | Where | How people lived and traded |
|---|---|---|
| Desert | The Sahara in the north; the Kalahari and Namib in the south | Herders often moved with their animals in search of water and grazing; some mined and traded salt |
| Semiarid (Sahel) | A narrow belt just south of the Sahara | Herding and trading livestock |
| Savannah grasslands | Wide belts north and south of the rainforest | Farming grain crops such as millet and sorghum |
| Tropical rainforest | Near the equator, in the Congo basin and along the Guinea coast | Growing yams and kola trees; trading gold |
| Mediterranean | The far north coast and the southern tip | Farming and trade across the Mediterranean Sea |
Rivers and seas
Five major rivers carried people and goods into the interior. The Nile, usually ranked as the world's longest river, flows north to the Mediterranean and supported Egypt and Nubia. The Niger arcs through West Africa past trading cities like Timbuktu and Gao. The Congo drains a huge basin in Central Africa. The Zambezi and the Orange cross southern Africa.
Africa is bordered by the Mediterranean Sea, the Red Sea, the Atlantic Ocean and the Indian Ocean. The Mediterranean linked North Africa to Europe and the Middle East. The Red Sea connected East Africa to Arabia, Rome and India, which helped Aksum grow rich (1.4). Indian Ocean winds carried traders between East Africa, Arabia, Persia, India and China (1.8). Being close to these waters helped early societies form and connected Africa to the world long before 1500.
Why people settled in the Sahel and savannah
The name Sahel comes from an Arabic word for 'shore'. Traders thought of it as the shore of a sea of sand, where camel caravans crossing the Sahara finally reached land. That's one reason the great West African empires of Ghana, Mali and Songhai grew up in this zone (1.5).
- Water routes: rivers like the Niger let people move goods and travel.
- Fertile land: good soil supported farming and raising animals.
- A middle position: these lands sat between the Sahara to the north and the forests to the south, so traders from both zones met there.
Different zones, different goods
Because each zone produced different things, people had good reasons to trade. Desert peoples had salt, which everyone needed to preserve food and stay healthy in the heat. Forest and savannah peoples had gold, kola nuts and grain. Sahel herders raised cattle, camels and horses, animals that struggled in the rainforest, where the tsetse fly spreads a disease deadly to livestock.
The classic example is the salt-for-gold trade: salt from Saharan mines moved south, gold moved north, and the towns in between grew rich by taxing and organizing the exchange.
Worked examples
Try each one yourself first, then open the solution.
- Example 1
A causation chain from a map
Using a map of Africa's climate regions, explain how geography encouraged trade between the Sahara and the rainforest zone.
Show the solutionHide the solution
- Step 1: Identify what each zone produced: salt in the desert, gold and kola nuts in the forest region.
- Step 2: Explain the need: each zone lacked what the other had.
- Step 3: Name the link: the Sahel and savannah sat between them, with rivers like the Niger.
- Step 4: State the effect: trading towns and empires grew in the middle zone.
Answer: Model answer: The Sahara produced salt, while the forest region in the south produced gold and kola nuts, so each zone needed goods the other had. The Sahel and savannah lay between them and had rivers like the Niger, so traders met there, and cities and empires such as Mali grew rich by controlling this exchange.
Common mistakes
- Picturing Africa as all jungle or all desert. Rainforest covers only part of the continent; savannah is far more widespread.
- Mixing up the Sahara (the desert) and the Sahel (the semiarid belt south of it).
- Thinking the Nile flows south. It flows north, into the Mediterranean.
On the exam
- Maps often appear as sources. Be ready to describe a pattern on the map and connect it to settlement or trade.
- Use specific names (the Sahel, the Niger River, the Red Sea) instead of 'the environment' when you explain a cause.
