Africa is the second-largest continent by both land area and population. As of 2026, it remains a focal point for global geopolitics due to its demographic dividend, vast mineral wealth, and increasing regional integration.
Physical and Political Geography: Key Facts
Africa is the only continent through which the Equator (0°), the Tropic of Cancer (23.5° N), and the Tropic of Capricorn (23.5° S) all pass. It is also bisected by the Prime Meridian (0° longitude), which passes through Algeria, Mali, Burkina Faso, Togo, and Ghana.

These nations lack direct access to the sea, which significantly impacts their trade and security dynamics.
- Northern/Central: Chad, Central African Republic, South Sudan.
- Western: Mali, Burkina Faso, Niger.
- Eastern: Ethiopia (largest landlocked country by population), Rwanda, Burundi, Uganda.
- Southern: Botswana, Malawi, Zambia, Zimbabwe, Lesotho (enclaved by South Africa), Eswatini.
Major Regional Organizations and Integration
The move toward “African Solutions to African Problems” has strengthened regional blocs.
The African Union (AU)
- Headquarters: Addis Ababa, Ethiopia.
- Significance: It is the successor to the Organisation of African Unity (OAU). In 2023, the AU became a permanent member of the G20, a major milestone for African representation in global governance.

| SADC | Southern African Development Community | South Africa, Angola, Botswana (Focus: Economic integration). |
| EAC | East African Community | Kenya, Tanzania, Rwanda (Focus: Common market). |
| COMESA | Common Market for Eastern and Southern Africa | Largest REC by number of member states. |
Strategic Water Bodies and Choke Points
Africa controls some of the world’s most vital maritime trade routes.
- Suez Canal: Connects the Mediterranean Sea to the Red Sea (Egypt).
- Bab-el-Mandeb: A strategic strait between Djibouti/Eritrea and Yemen, connecting the Red Sea to the Gulf of Aden.
- Strait of Gibraltar: Separates Morocco from Spain (Africa from Europe).
- Mozambique Channel: Separates Madagascar from the African mainland.
Economic and Demographic Trivia for Prelims
- Resource Wealth: Africa holds 30% of the world’s mineral reserves, including 90% of its chromium and platinum.
- AfCFTA: The African Continental Free Trade Area (AfCFTA), which became operational recently, creates the world’s largest free trade area by the number of participating countries.
- Demographic Dividend: Africa has the world’s youngest population; Niger has the lowest median age globally (approx. $15$ years).
- New Capitals: Some countries have shifted or are shifting capitals for better administration (e.g., Burundi moved from Bujumbura to Gitega; Egypt is building a New Administrative Capital to replace Cairo’s congestion).
