BharatNotes The Middle East and Africa are two of the most geopolitically consequential regions for India — together they account for the majority of India's energy imports, host the largest segment of the Indian diaspora, and are the focus of India's expanding diplomatic and economic engagement. A thorough understanding of their physical geography is the foundation for analysing regional politics, conflicts, and India's strategic interests.
Part A: Middle East — Physical Geography
1. Major Physical Regions
| Region | Description | Key Countries |
|---|---|---|
| Arabian Peninsula | Large peninsula bounded by Red Sea (west), Arabian Sea (south), Persian/Arabian Gulf (east); dominated by desert | Saudi Arabia, UAE, Oman, Yemen, Kuwait, Qatar, Bahrain |
| Mesopotamia | "Land between the rivers" — Tigris and Euphrates floodplains; historically world's first civilisations | Iraq |
| The Levant | Eastern Mediterranean coastal strip; historically contested | Syria, Lebanon, Israel, Jordan, Palestinian territories |
| Anatolian Plateau | High central plateau; source of Tigris and Euphrates | Turkey (Türkiye) |
| Iranian Plateau | Elevated interior plateau; ringed by Zagros and Elburz mountains | Iran, Afghanistan (western margins) |
2. Mountain Ranges
| Range | Location | Notes |
|---|---|---|
| Zagros Mountains | Western Iran, extending into Iraq | Major fold mountain system; oil-bearing strata |
| Elburz (Alborz) Mountains | Northern Iran, south of Caspian Sea | Contains Mt. Damavand (5,609 m) — Iran's highest peak |
| Taurus Mountains | Southern Turkey | Headwaters of Euphrates |
| Hejaz Mountains | Western Saudi Arabia (along Red Sea coast) | Highest peaks on Arabian Peninsula |
3. Key Deserts of the Middle East
| Desert | Location | Notable Feature |
|---|---|---|
| Arabian Desert | Arabian Peninsula | World's 4th largest desert by area; spans Saudi Arabia, UAE, Oman, Yemen |
| Rub' al Khali (Empty Quarter) | Southern Saudi Arabia, UAE, Oman, Yemen | World's largest continuous sand desert (~650,000 sq km) |
| Syrian Desert | Syria, Iraq, Jordan | Semi-desert/steppe between Euphrates and Mediterranean |
| Negev Desert | Southern Israel | Strategic importance; Israel uses drip irrigation here |
4. Key Rivers of the Middle East
| River | Origin | Course | Significance |
|---|---|---|---|
| Nile | East African highlands (Burundi/Rwanda — White Nile source; Ethiopian Highlands — Blue Nile source) | Flows north through Sudan and Egypt to Mediterranean | Traditionally considered world's longest river at 6,650 km (though the Amazon is now measured similarly); lifeblood of Egypt; 97% of Egypt's population lives in Nile Valley |
| Tigris | Eastern Turkey (Taurus/Pontic mountains) | Flows SE through Turkey and Iraq; joins Euphrates at Shatt al-Arab | Ancient Mesopotamia; Baghdad is on the Tigris |
| Euphrates | Eastern Turkey | Flows through Syria then Iraq; meets Tigris at Shatt al-Arab estuary into Persian Gulf | Longest river in western Asia (~2,800 km) |
| Jordan River | Mount Hermon (Lebanon/Syria) | Flows south through Sea of Galilee to Dead Sea | Holy significance; source of Israeli-Palestinian water conflict |
Shatt al-Arab: The confluence waterway where the Tigris and Euphrates join before entering the Persian Gulf; forms part of Iran-Iraq border; contested (Algiers Agreement 1975).
5. Strategic Geographical Features
Dead Sea: Landlocked lake on the Jordan-Israel-Palestinian Authority border. It sits at approximately 430 metres below sea level — the lowest point on Earth's land surface. Its high salinity (~34%) makes it impossible to sustain aquatic life. It is shrinking rapidly due to water diversion.
Bosphorus and Dardanelles Straits: Controlled by Turkey; connect Black Sea to Mediterranean; governed by the Montreux Convention (1936).
6. Oil and Gas — The Middle East's Defining Resource
The Persian Gulf region is the world's most hydrocarbon-rich area:
| Feature | Data |
|---|---|
| Share of world's proven oil reserves | ~50% of global proven oil reserves in the Gulf region |
| Strait of Hormuz oil flow (2024) | ~20 million barrels/day = about 20% of global petroleum liquids consumption; ~27% of global seaborne oil trade |
| Saudi Arabia | World's largest crude oil exporter; home of Saudi Aramco — world's most profitable company |
| Qatar | World's largest LNG exporter |
OPEC (Organisation of Petroleum Exporting Countries): Founded 14 September 1960 in Baghdad. The five original founding members were Iran, Iraq, Kuwait, Saudi Arabia, and Venezuela. The UAE joined later (1967), as did Qatar (1961, withdrew 2019), Libya (1962), Algeria (1969), Nigeria (1971), and others. Headquartered in Vienna since 1965.
India's energy dependency: India imports ~87% of its crude oil; the Middle East accounts for approximately 60–65% of India's crude oil imports. Energy security is thus central to India-Middle East relations.
7. Strategic Waterways
Strait of Hormuz:
- Narrow strait between Iran and Oman at the mouth of the Persian Gulf
- Minimum width: ~34 km; the navigable channel is only ~3 km wide in each direction
- In 2024, approximately 20% of global petroleum liquids consumption passed through this strait
- Any closure would devastate global oil markets — the world's most critical energy chokepoint
Suez Canal:
- Artificial sea-level waterway in Egypt connecting the Mediterranean Sea to the Red Sea through the Isthmus of Suez
- Length: 193.3 km; opened 17 November 1869 under Egyptian Khedive Ismail; built by Ferdinand de Lesseps
- Nationalised by Egypt's Nasser in 1956 (triggering the Suez Crisis); controlled by Suez Canal Authority
- Importance: Reduces the sea voyage between Europe and Asia by ~7,000 km versus going around the Cape of Good Hope
- 2021 Ever Given blockage: Six-day blockage by a container ship cost global trade ~$9.6 billion/day
Bab el-Mandeb:
- Strait connecting the Red Sea to the Gulf of Aden (and onwards to the Arabian Sea/Indian Ocean)
- Located between Djibouti (Horn of Africa) and Yemen
- Width: ~29 km at narrowest point
- Importance: All traffic through the Suez Canal must also pass through Bab el-Mandeb; Houthi attacks on shipping (2023–2025) in this area disrupted global supply chains and forced ships to reroute around Africa
8. India-Middle East Relations — Geographic Dimensions
- IMEC (India-Middle East-Europe Economic Corridor): Announced at G20 New Delhi Summit (September 2023); aims to connect India through UAE, Saudi Arabia, Jordan, Israel, to Europe via rail and sea — a strategic alternative to China's BRI
- Energy security: Persian Gulf oil and Gulf diaspora remittances ($129.1 billion total remittances, large share from GCC)
- Indian Ocean security: India's naval presence in the Arabian Sea monitors Strait of Hormuz approaches and Bab el-Mandeb
Part B: Africa — Physical Geography
9. Major Physical Regions

| Great Rift Valley | East Africa (Ethiopia to Mozambique) | Tectonic feature caused by diverging plates; contains Africa's Great Lakes |
| Ethiopian Highlands | Ethiopia | "Roof of Africa"; source of Blue Nile; highest plateau |
| Congo Basin | Central Africa (DRC) | World's 2nd largest tropical rainforest (after Amazon); 3.4 million sq km |
| Sahel | Sub-Saharan semi-arid belt | Transition zone between Sahara and savanna; desertification, food insecurity |
| Horn of Africa | NE Africa | Strategic; Somalia, Ethiopia, Eritrea, Djibouti |
| Cape Region | South Africa | Mediterranean climate; biodiversity hotspot |
10. Mountains of Africa
| Range/Peak | Location | Elevation |
|---|---|---|
| Mt. Kilimanjaro | Tanzania | 5,895 m — Africa's highest peak; dormant volcano |
| Mt. Kenya | Kenya | 5,199 m |
| Atlas Mountains | Morocco, Algeria, Tunisia (NW Africa) | Fold mountains; separate Mediterranean coast from Sahara |
| Drakensberg | South Africa/Lesotho | Highest range in Southern Africa; ~3,482 m |
| Ethiopian Highlands | Ethiopia | Dissected plateau; average elevation 1,800–2,400 m |
| Rwenzori Mountains | Uganda/DRC | "Mountains of the Moon"; glaciated |
11. Major Rivers of Africa
| River | Length | Key Features |
|---|---|---|
| Nile | 6,650 km (traditionally world's longest) | Two tributaries: White Nile (source in Great Lakes region) + Blue Nile (from Lake Tana, Ethiopia — provides ~85% of volume); flows N through Sudan, Egypt |
| Congo (Zaire) | ~4,700 km | World's deepest river (depths to 220 m); 2nd largest by discharge (after Amazon); drains the Congo rainforest basin |
| Niger | ~4,180 km | "Boomerang river" — flows NE into the Sahel then SE to Gulf of Guinea; supports the Inland Niger Delta in Mali |
| Zambezi | ~2,574 km | Flows east to Indian Ocean; site of Victoria Falls (world's largest waterfall by width — 1,708 m) |
| Orange (Gariep) | ~2,200 km | South Africa; flows west to Atlantic |
| Limpopo | ~1,750 km | Southern Africa; "great grey-green, greasy Limpopo River" (Kipling) |
Victoria Falls: Located on the Zambezi River at the Zambia-Zimbabwe border; local name Mosi-oa-Tunya ("The Smoke That Thunders"). The falls are approximately 108 m high and 1,708 m wide — considered the world's largest waterfall by combined width and height.
12. Major Deserts of Africa
| Desert | Location | Area/Feature |
|---|---|---|
| Sahara | North Africa | World's largest hot desert (~9 million sq km; roughly the size of the USA); covers Algeria, Libya, Egypt, Mali, Niger, Chad, Sudan, Mauritania, Morocco, Tunisia |
| Namib | Coastal Namibia/Angola | World's oldest desert (55–80 million years old); fog desert; coastal |
| Kalahari | Botswana, Namibia, S. Africa | Semi-arid savanna (not a true desert); receives some rainfall |
13. African Great Lakes — The Great Rift System
The Great Rift Valley is the defining geological feature of East Africa — a tectonic rift where the African Plate is slowly splitting. It contains Africa's most significant lakes:
| Lake | Key Fact | Countries |
|---|---|---|
| Victoria | Africa's largest lake; world's 2nd largest freshwater lake by surface area (after Lake Superior, N. America); ~59,947 sq km | Tanzania, Uganda, Kenya |
| Tanganyika | World's longest lake (~676 km); world's 2nd deepest freshwater lake (1,470 m) | DRC, Tanzania, Burundi, Zambia |
| Malawi (Nyasa) | 3rd deepest freshwater lake | Malawi, Tanzania, Mozambique |
| Turkana | World's largest permanent desert lake; alkaline | Kenya (and Ethiopia) |
| Albert, Edward, Kivu | Smaller Rift Valley lakes | Uganda/DRC |
Note for Prelims: Lake Victoria is Africa's largest and the world's 2nd largest freshwater (not 3rd — a common error in older study materials). It is the world's largest tropical lake.
14. Climate Zones of Africa (Equator Outward)
| Zone | Location | Characteristics |
|---|---|---|
| Equatorial/Tropical Rainforest | Congo Basin, Coastal West Africa | Heavy rainfall year-round (>2,000 mm); dense forest |
| Tropical Savanna (Sudan-type) | North and south of equatorial belt | Wet season + dry season; tall grass, scattered trees; elephants, lions |
| Semi-arid (Sahel) | Belt south of Sahara | 250–500 mm rainfall; droughts; desertification; food insecurity |
| Desert | Sahara (N), Namib/Kalahari (S) | <25 mm rainfall; extreme temperatures |
| Mediterranean | NW Africa (Morocco, Tunisia) and SW Africa (Cape) | Hot dry summers, cool wet winters |
| Subtropical Highland | Ethiopian Highlands, E. Africa | Cooler due to elevation |
15. Africa's Strategic Resources
| Resource | Country/Region | Global Significance |
|---|---|---|
| Cobalt | Democratic Republic of Congo (DRC) | DRC produced ~74% of global cobalt in 2024 (some estimates higher); critical for EV batteries |
| Gold and platinum | South Africa | Witwatersrand Basin; historically world's largest gold producer; leading platinum producer |
| Oil and gas | Nigeria, Angola, Libya, Algeria, Egypt | Nigeria = Africa's largest oil producer; major OPEC member |

| Chromium and manganese | South Africa | Critical minerals for steel and batteries |
| Rare earth elements | DRC, Madagascar, South Africa | Growing strategic competition (China vs West) |
| Geothermal energy | Kenya | Africa's largest geothermal power capacity; ~700 MW installed |
16. India-Africa Relations — Geographic Dimensions
- African Union membership in G20 (2023): India championed AU's permanent membership in the G20, granted at the New Delhi Summit — a significant diplomatic achievement
- India-Africa Forum Summit (IAFS): Third summit held in 2015 in New Delhi; announced $600 million in grants and $10 billion credit lines; fourth summit pending
- IMEC and Africa: The India-Middle East-Europe Corridor connects through Africa's adjacent Red Sea corridor
- DRC cobalt: Critical for India's EV transition; India's KABIL (Khanij Bidesh India Ltd) is seeking cobalt and lithium overseas
- Strategic chokepoints: Bab el-Mandeb (between Africa and Yemen), Mozambique Channel (Indian Ocean shipping), Cape of Good Hope (alternative to Suez) — all affect India's maritime security

- Africa geography connects to India's strategic interests, critical minerals, IAFS, G20 AU membership
- Always connect physical geography to economic and geopolitical dimensions for full marks
Recent Developments (2024–2026)
Red Sea Crisis — Houthi Attacks Disrupt 8.7% of Global Trade (2024–2025)
Since November 2023, Houthi rebel attacks on commercial shipping in the Red Sea and Gulf of Aden have triggered the most severe maritime chokepoint disruption since the 1973 oil crisis. Over 190 attacks were recorded through October 2024; ships passing through the Suez Canal fell from 2,068 in November 2023 to approximately 877 by October 2024, and Bab-el-Mandeb transits hit a record low in June 2025 — down 65% from June 2023. The Red Sea corridor normally handles 8.7% of global seaborne trade (over $2 trillion in cargo value); rerouting via the Cape of Good Hope adds 11,000 nautical miles, ~10 days, and $1 million in fuel per voyage. Oil flows through Bab-el-Mandeb fell from 8.8 million barrels/day to ~4 million barrels/day by August 2024. A US–Houthi bilateral ceasefire was announced on May 6, 2025, and Houthi attacks on international shipping halted following a Gaza peace plan (October 2025). India's energy imports, fertiliser supplies (Middle East accounts for ~1/3 of global urea exports), and diaspora remittance flows are all directly affected.
UPSC angle: Red Sea disruption links physical geography (Bab-el-Mandeb, Suez Canal) to India's energy security, logistics costs, and West Asia policy — a high-probability GS2/GS3 Mains theme. AIKEYME (Africa-India Key Maritime Engagement) naval exercise, inaugurated April 13, 2025 in Tanzania, reflects India's deepening strategic role in African waters.
Sudan Civil War and Africa's Humanitarian Crisis (2023–2025)
The Sudanese civil war (SAF vs. RSF), which began April 2023, has become Africa's largest humanitarian emergency by 2025 — 9.6 million internally displaced, 4.3 million refugees in neighbouring countries, and 30.4 million Sudanese requiring humanitarian assistance. The SAF regained Khartoum by March 2025 after RSF had controlled it. Sudan's position astride the Nile, bordering 7 countries, and proximate to the Red Sea gives this conflict major geostrategic significance. The AU's inclusion in the G20 (South Africa summit, 2023) marks Africa's growing multilateral weight; PM Modi's MAHASAGAR vision (March 2025, announced in Mauritius) extends India's blue economy and cooperative model across the Indian Ocean rim, encompassing East African nations.
UPSC angle: Sudan crisis connects physical geography (Nile basin, Sahel corridor) to GS2 displacement and regional security. India–Africa engagement (IAFS, AIKEYME, MAHASAGAR) is a recurring GS2 bilateral theme; Africa's critical mineral wealth (DRC cobalt, South Africa PGMs, Tanzania lithium) increasingly drives geopolitical competition.
