Africa

Introduction, Location and Extent

• Africa is the second-largest continent after Asia, covering about 30.37 million sq. km, nearly 20% of the world’s land area.
• It extends from 37°N to 35°S latitude and 17°W to 51°E longitude.
• Africa is bounded by the Mediterranean Sea (north), Atlantic Ocean (west), Indian Ocean (east), and Southern Ocean (south).
• The Equator, Tropic of Cancer, and Tropic of Capricorn pass through the continent, contributing to diverse climatic conditions.
• Africa comprises 54 countries and has a population exceeding 1.5 billion.
• It is known as the “Plateau Continent” because most of its surface consists of elevated plateaus rather than extensive plains.
• The average elevation ranges between 600–750 metres above sea level.
• Coastal plains are generally narrow and discontinuous.
• Rivers flowing from plateaus create numerous waterfalls, rapids, and gorges.
• Major plateaus include:
  • Ethiopian Plateau
  • East African Plateau
  • South African Plateau
  • Katanga Plateau
  • Jos Plateau
• The plateau structure significantly influences Africa’s drainage system, climate, and economic activities.

Physiographic Divisions

Africa can broadly be divided into four physiographic regions:

1. Atlas Mountain Region
2. Central Plateau Region
3. East African Rift Valley System
4. Coastal Plains

Atlas Mountains

The Atlas Mountains extend across Morocco, Algeria and Tunisia and were formed during the Alpine Orogeny. They stretch for nearly 2,500 km and their highest peak is Mount Toubkal (4,167 m) in Morocco. These mountains act as a climatic barrier separating the Mediterranean coast from the Sahara Desert.

Central Plateau Region of Africa

• The Central Plateau Region is the largest physiographic division of Africa.
• It is the primary reason Africa is called the “Plateau Continent.”
• The region consists mainly of ancient crystalline rocks and extensive tablelands.
• Its average elevation ranges between 600–750 metres above sea level.
• It extends across Central and Southern Africa.
• Major plateaus include:
  • Katanga Plateau
  • South African Plateau
  • Jos Plateau
• Important basins within the region are:
  • Congo Basin
  • Chad Basin
  • Kalahari Basin
• Major rivers such as the Congo, Niger, Zambezi, and Orange originate from or flow across these plateaus.
• Numerous waterfalls and rapids provide significant hydropower potential.
• The region is rich in gold, diamonds, copper, cobalt, and uranium.
• Extensive savanna grasslands support agriculture, livestock rearing, wildlife, and tourism.

East African Rift Valley

The East African Rift Valley is one of the world’s most significant geological structures and represents an active divergent boundary between the Nubian and Somali plates. Stretching about 6,900 km, it contains volcanoes, geothermal zones and several lakes. Kenya has emerged as a leading producer of geothermal energy due to this rift system.

Coastal Plains of Africa

• The Coastal Plains form the fourth major physiographic division of Africa.
• These plains are generally narrow and discontinuous, stretching along the Atlantic Ocean, Indian Ocean, Mediterranean Sea, and Red Sea coasts.
• They are broader along the Gulf of Guinea and narrower on the eastern and southern coasts.
• Major coastal regions include the Nile Delta, Guinea Coast, Somali Coast, and Mozambique Coastal Plain.
• Important ports such as Alexandria, Lagos, Mombasa, Durban, and Djibouti are located here.
• Fertile soils and favorable climate support dense populations.
• Agriculture, fishing, tourism, and industries are concentrated in these areas.
• The Niger Delta is rich in petroleum resources.
• Coastal plains play a crucial role in Africa’s economy and international trade.

Mountains and Lakes

Though Africa is largely plateau-dominated, several important mountains exist. Mount Kilimanjaro (5,895 m) in Tanzania is the highest peak in Africa and the highest free-standing mountain in the world. Other important ranges include the Drakensberg Mountains, Rwenzori Mountains and Ethiopian Highlands. Kilimanjaro contains three volcanic cones—Kibo, Mawenzi and Shira.

The Great Rift Valley contains numerous lakes:

• Lake Victoria – largest lake in Africa and source of the White Nile.
• Lake Tanganyika – second deepest freshwater lake in the world.
• Lake Malawi – noted for exceptional biodiversity.
• Lake Turkana – largest desert lake.

Lake Victoria is also the largest tropical lake in the world.

Major Rivers of Africa

• Nile River
  • Traditionally regarded as the world’s longest river.
  • Formed by the confluence of the White Nile and Blue Nile at Khartoum (Sudan).
  • The Blue Nile contributes about 80–85% of the floodwater.
  • Supports Egypt, where nearly 95% of the population lives along the Nile Valley and Delta.
  • The Aswan High Dam provides flood control and hydroelectric power.
• Congo River
  • Africa’s second-longest and the world’s deepest river.
  • Crosses the Equator twice.
  • Ranks second after the Amazon in water discharge.
  • The Inga Dam Project has huge hydropower potential.
• Niger River
  • Vital river of West Africa.
  • Forms a large inland delta in Mali.
• Zambezi River
  • Famous for Victoria Falls.
  • Hosts major hydropower projects such as Kariba Dam and Cahora Bassa Dam.

Climate of Africa

Africa’s climate is influenced by latitude, altitude, ocean currents, relief and the seasonal movement of the Inter-Tropical Convergence Zone (ITCZ). About three-fourths of the continent lies within the tropics.

Created by ForumIAS

Ocean Currents

Ocean currents strongly affect African climate.

• Canary Current (cold): causes aridity along northwest Africa.
• Benguela Current (cold): responsible for the Namib Desert and rich fisheries.
• Guinea Current (warm): brings moisture to West Africa.
• Mozambique Current and Agulhas Current (warm): influence southeastern Africa.

Natural Vegetation and Wildlife

Africa displays a symmetrical arrangement of vegetation belts.

Equatorial Rainforests

Centered on the Congo Basin, these forests contain mahogany, ebony and rubber trees and store enormous quantities of carbon.

Savanna Grasslands

Covering nearly half of Africa, these grasslands contain acacia and baobab trees and support livestock and wildlife tourism.

Steppe and Desert Vegetation

The Sahel contains drought-resistant shrubs, while desert regions support thorny plants and date palms around oases.

Mediterranean Vegetation

Olive, cork oak and citrus trees dominate the Mediterranean regions.

Wildlife

Africa is famous for its biodiversity. Major wildlife regions include Serengeti, Masai Mara, Okavango Delta and Virunga. The famous Big Five are:

1. Lion
2. Leopard
3. Elephant
4. Rhinoceros
5. Buffalo

The annual migration of over 1.5 million wildebeest between Serengeti and Masai Mara is the world’s largest terrestrial animal migration.

Mineral Resource

Agriculture

Agriculture employs a large proportion of Africa’s workforce.

Major food crops include:

• Maize
• Millet
• Sorghum
• Cassava
• Rice

Nigeria is the world’s largest producer of cassava. Plantation agriculture produces cocoa, coffee, tea, cotton and palm oil. Côte d’Ivoire and Ghana together account for more than 60% of global cocoa production.

Fisheries and Industries

Rich fisheries are associated with the Canary and Benguela Currents. Morocco is Africa’s leading fisheries exporter. Major industrial economies include South Africa, Egypt, Nigeria and Algeria.

South Africa possesses the continent’s most diversified industrial base, with industries ranging from mining and steel to automobiles and chemicals. Egypt’s industries are concentrated around the Nile Valley and Suez Canal Corridor.
