Transport, Communication and Trade

(Class 12 Geography – Human Geography, CBSE 2025–26)

1. Introduction

Geography is not only about studying land, people, and resources – it is also about how people connect with each other.
This connection happens through Transport, Communication, and Trade.

• Transport = movement of goods, people, and ideas from one place to another.
• Communication = exchange of information, ideas, and messages.
• Trade = buying, selling, and exchanging goods and services.

👉 Together, these three make the lifelines of human civilization, ensuring economic growth, cultural exchange, and global integration.

2. Importance of Transport and Communication

Transport and communication are called the “wheels of economy”.

✨ Why important?

🔹 Facilitate movement of raw materials, finished products, and people.
🔹 Connect producers and consumers → strengthen markets.
🔹 Spread knowledge, culture, and technology.
🔹 Promote national integration and international cooperation.
🔹 Essential for defence, disaster relief, and emergencies.
🔹 Backbone of globalisation.

Example:

• Indian IT industry (Bengaluru) thrives only because of fast communication (internet, satellites).
• Agriculture in Punjab and Haryana connects with markets in Delhi via roads & railways.

3. Modes of Transport

Transport is mainly of 3 types:

A. Land Transport

1. Roadways
   • Flexible & door-to-door service.
   • Cheap for short distance & light goods.
   • India’s Golden Quadrilateral connects Delhi, Mumbai, Chennai, and Kolkata.
   • Limitations: traffic, accidents, pollution.
2. Railways
   • Best for bulky & long-distance goods.
   • Developed first in 19th century (England, 1825).
   • India has world’s largest passenger rail network.
   • Examples of global routes:
     • Trans-Siberian Railway (Moscow–Vladivostok, longest in world).
     • Trans-Canadian Railway (Montreal–Vancouver).
3. Pipelines
   • For oil, gas, water.
   • Safe & cheap once established.
   • Example: Druzhba pipeline (Russia to Europe),
   • In India → Hajira–Vijaipur–Jagdishpur Gas Pipeline (HVJ).

B. Water Transport

1. Inland Waterways
   • Rivers, canals, lakes.
   • Cheap but slow.
   • Example: Ganga–Bhagirathi–Hooghly system, Mississippi River, Rhine River.
2. Ocean Routes
   • Carry bulk of world trade (almost 70% goods by volume).
   • Examples:
     • North Atlantic Route (most important, connects N. America & Europe).
     • Suez Canal Route (connects Mediterranean Sea with Red Sea, saves 7000 km).
     • Panama Canal Route (connects Atlantic & Pacific Oceans).

C. Air Transport

• Fastest & best for high-value, perishable goods.
• Connects remote, inaccessible regions.
• Expensive, affected by weather.

Examples:

• Dubai International Airport – world’s busiest for international passengers.
• India’s Indira Gandhi International Airport (Delhi) – busiest in South Asia.

4. Global Transport Networks

Transport creates a global web of connectivity.

✨ Major Networks:

🔹 Trans-Siberian Railway – 9,334 km, links Russia west to east.
🔹 Trans-African Highways – connects north to south of Africa.
🔹 Pan-American Highway – Alaska (USA) to Chile (S. America).
🔹 Silk Route (Historical) – trade of silk, spices, ideas, culture.

5. Communication

Communication = transmission of ideas, messages, news, and information.

A. Traditional Communication

• Postal system, letters, radio, newspapers.
• Still important in rural areas.

B. Modern Communication

• Telecommunication – landline, mobile, satellite phones.
• Internet – fastest medium, global connectivity.
• Satellite Communication – GPS, weather forecasting, TV, DTH.
• Social Media & Digital Platforms – WhatsApp, X (Twitter), Instagram → instant global communication.

Example:

• India’s ISRO satellites support TV, GPS, weather, disaster alerts.
• Digital India Mission promotes internet penetration in villages.

6. Trade – Meaning and Types

Trade = exchange of goods and services between producers and consumers.

Types of Trade

1. Internal Trade – within a country.
   • Local markets, wholesale, retail.
   • Example: Vegetables sold in a local mandi.
2. International Trade – between countries.
   • Imports = goods purchased from outside.
   • Exports = goods sold to outside.
   • Example: India exports IT services, imports crude oil.

7. World Trade Patterns

Trade is uneven because of unequal resource distribution.

✨ Major commodities traded:
🔹 Oil & petroleum products → Middle East, Russia.
🔹 Machinery, electronics → USA, Germany, Japan, China.
🔹 Agricultural products → Brazil (coffee), India (tea, rice), Vietnam (rice).
🔹 Services → India (IT, BPO).

✨ Major trade partners:

• USA–China (largest bilateral trade).
• India–UAE, India–USA, India–China.

✨ World Trade Organisation (WTO):

• Formed in 1995.
• Promotes free & fair global trade.

8. Transport, Communication and Trade in India

India = a fast-growing economy where transport and communication are lifelines.

✨ Transport in India

• Roads → National Highways (NH 44 longest).
• Railways → 4th largest in world.
• Waterways → NW-1 (Allahabad to Haldia, Ganga).
• Airways → Expansion under UDAN scheme (regional airports).

✨ Communication in India

• World’s second-largest telecom network.
• Digital India → promotes e-governance, rural internet.
• ISRO satellites → vital for telecommunication.

✨ Trade in India

• Exports: petroleum products, IT services, textiles, gems.
• Imports: crude oil, gold, machinery, electronics.
• Major partners: USA, UAE, China, EU.

9. Factors Affecting Development

Development of transport, communication, and trade depends on:

🔹 Physical factors – relief, climate, natural barriers.
🔹 Economic factors – industrialization, trade demand.
🔹 Political factors – stability, government policies.
🔹 Technological factors – availability of modern infrastructure.
🔹 Social factors – population density, urbanization.

10. Problems and Challenges

✨ Transport challenges: congestion, pollution, poor infrastructure.
✨ Communication challenges: digital divide, cybercrimes, privacy.
✨ Trade challenges: imbalance, WTO disputes, tariffs, geopolitical tensions.
✨ Environmental challenges: greenhouse gases, deforestation for highways, oil spills.

11. Case Studies / Examples

📌 Suez Canal – cut travel time between Europe & Asia by 7,000 km.
📌 Panama Canal – key for US–Asia trade.
📌 Trans-Siberian Railway – backbone of Russia’s economy.
📌 Golden Quadrilateral (India) – improved road connectivity.
📌 Mumbai Port – India’s busiest port.

12. Key Terms for Exam

• Globalisation – integration of world economy.
• E-commerce – trade via internet.
• Balance of Trade – difference between exports & imports.
• Trade Surplus – exports > imports.
• Trade Deficit – imports > exports.
• Digital Divide – inequality in access to ICT.
