World Economic Geography – NDA Geography Notes

Exam Relevance: High Frequency | City-Industry Match, Canal Connections, Straits Match, World Rivers, Caspian Sea Landlocked, Victoria Falls

Reading Time: 25–30 minutes | Last Updated: 2026

Economic geography studies where economic activities take place and why: where industries locate, which trade routes connect the world, and which straits and canals are critical chokepoints for global commerce.

For NDA, this chapter is tested primarily through two types of questions: city-industry match questions (Detroit – automobiles, Antwerp – diamond cutting) and straits-canals questions (Kiel Canal connects which seas, which strait separates which countries). These are direct factual questions. The chapter also covers world rivers flowing to their seas and specific islands.


Major Industrial Centres of the World

CityCountryFamous IndustryNDA Tag
DetroitUSAAutomobiles (“Motor City”: GM, Ford, Chrysler)[NDA 2008-II]
AntwerpBelgiumDiamond cutting and trade
RotterdamNetherlandsShipbuilding + largest port in Europe[NDA 2014-II]

EdmontonCanadaOil; capital of Alberta
CairnsAustraliaTourism, tropical gateway
LeipzigGermanyPublishing, trade fairs
LorraineFranceIron and steel
CumberlandUKIron and steel (historical)
HarbinChinaSteel
TokyoJapanShipbuilding, electronics

Detroit = Automobiles. [NDA 2008-II] Rotterdam = Shipbuilding. [NDA 2014-II] These two are most directly tested and most commonly confused with each other.

Macau (China’s Special Administrative Region) is situated close to the Pearl River Estuary: near Hong Kong.

Orient Express: the famous railway historically connecting Western Europe to Istanbul, passing through Germany, France, Austria, Hungary, and Romania.


World Canals

Suez CanalMediterranean Sea ↔ Red SeaEgyptSea-level (no locks); opened 1869[NDA 2008-II
Kiel CanalBaltic Sea ↔ North SeaGermanyWorld’s busiest artificial waterway by ship count[NDA 2008-II]
Panama CanalCaribbean (Atlantic) ↔ PacificPanamaHas locks; opened 1914

Strategic importance of Suez Canal, Strait of Hormuz, and Strait of Gibraltar: they control access to vital trade routes. [NDA 2012-I]


Major Straits of the World

Palk StraitBay of Bengal ↔ Gulf of MannarBetween India and Sri Lanka

Dover StraitNorth Sea ↔ English ChannelBetween UK and France
Florida StraitAtlantic OceanBetween USA (Florida) and Cuba

Cook Strait separates the North and South Islands of New Zealand. [NDA 2009-II]

Bass Strait is NOT in Asia: it is between mainland Australia and Tasmania.


Landlocked Water Bodies

The Caspian Sea is completely landlocked: surrounded by Kazakhstan, Russia, Azerbaijan, Iran, and Turkmenistan. It has no natural connection to any ocean. It is technically the world’s largest lake.

Caspian Sea is a landlocked water body. [NDA 2024-II]

The Mediterranean connects to the Atlantic (through Gibraltar). The Black Sea connects to the Mediterranean (through Bosporus). The Red Sea connects to the Indian Ocean.


World Rivers and Their Destinations

European Rivers

RiverDrains IntoKey Notes
DanubeBlack SeaFlows through Vienna, Budapest, Belgrade: NOT Prague
RhineNorth SeaRotterdam at mouth; major industrial transport route
RhoneMediterranean SeaFrance
LoireBay of BiscayFrance
VolgaCaspian SeaRussia’s longest river: NOT the Black Sea
DnieperBlack SeaUkraine/Russia
DonBlack SeaRussia

The Volga does NOT drain into the Black Sea: it drains into the Caspian Sea.

Which river does NOT drain into the Black Sea? = Volga. The Dnieper, Don, and Danube all drain into the Black Sea.

Prague is on the Vltava River: NOT the Danube. The Danube flows through Vienna, Bratislava, Budapest, and Belgrade.

Asian and African Rivers

Irrawaddy River: flows through Myanmar; major city on its banks is Yangon (Rangoon). [NDA 2007-I]

Victoria Falls: on the Zambezi River: on the border between Zambia and Zimbabwe. One of the world’s largest waterfalls, named by explorer David Livingstone in 1855. [NDA 2007-II]

Mekong Delta: in Vietnam: the river flows from Tibet through China, Myanmar, Laos, Thailand, Cambodia, and forms its delta in Vietnam before emptying into the South China Sea.

Buenos Aires and Montevideo: on the banks of River Plate (Río de la Plata). Montreal: on the St Lawrence River, Canada.


Island Geography

Isle of Youth (Isla de la Juventud): found near Cuba: the second largest island belonging to Cuba. [NDA 2012-I]

Faroe Islands: in the Atlantic Ocean between Scotland and Iceland: a self-governing territory of Denmark. The name comes from Old Norse meaning “sheep”, also known as the Sheep Islands. [NDA 2014-I]

Bermuda Islands: in the North Atlantic Ocean: a British Overseas Territory.New Guinea: among Borneo, Madagascar, New Guinea, and Sumatra: New Guinea is the largest. It is the world’s second largest island (after Greenland). Borneo is third, Madagascar fourth, Sumatra sixth
