Chapter 7: Lifelines of National Economy

Overview

Transportation, communication, and trade are essential for the development of a nation. These are considered the lifelines of a country’s economy as they facilitate movement, connectivity, and exchange of goods and services. This chapter explores different modes of transportation, communication systems, and the importance of international trade and tourism in India’s economic development.

Transportation in India

Efficient transportation systems are crucial for economic growth and social development. The various modes of transportation in India include:

A. Roadways

  • India has one of the largest road networks in the world, covering over 5.5 million kilometers.
  • Roads are classified into Golden Quadrilateral, National Highways, State Highways, District Roads, Rural Roads, and Border Roads.
  • Golden Quadrilateral: Connects Delhi, Mumbai, Chennai, and Kolkata, facilitating fast movement of goods and people.
  • National Highways (NH): Managed by the National Highways Authority of India (NHAI), they connect major cities and industrial hubs.
  • State Highways: Constructed and maintained by state governments, linking district headquarters.
  • District Roads: Provide connectivity between local towns and rural areas.
  • Rural Roads: Constructed under schemes like the Pradhan Mantri Gram Sadak Yojana (PMGSY) to enhance rural connectivity.
  • Border Roads: Constructed by the Border Roads Organisation (BRO) to facilitate defense and trade along border areas.
  • Advantages of Road Transport:
    • Provides door-to-door service.
    • Suitable for short and medium distances.
    • Essential for remote and hilly areas.
    • More flexible compared to railways.

B. Railways

  • Indian Railways is one of the largest rail networks in the world, covering over 68,000 km.
  • Plays a vital role in long-distance travel and goods transportation.
  • Classification based on Gauge:
    • Broad Gauge: Widely used for passenger and freight transport (1.676 m).
    • Meter Gauge: Found in some rural and hilly areas (1.0 m).
    • Narrow Gauge: Used in mountainous regions (0.762 m and 0.610 m).
  • Electrification and Modernization:
    • Reduces dependency on fossil fuels.
    • Enhances efficiency and speed of trains.
    • Introduction of bullet trains and semi-high-speed trains like Vande Bharat.
  • Challenges:
    • Overcrowding in passenger trains.
    • High maintenance costs.
    • Delays and outdated infrastructure in some areas.

C. Airways

  • The fastest mode of transport, mainly used for passengers, express cargo, and emergency services.
  • Domestic and International Connectivity:
    • India has over 137 operational airports, managed by the Airports Authority of India (AAI).
    • Major international airports include Indira Gandhi International Airport (Delhi), Chhatrapati Shivaji Maharaj International Airport (Mumbai), and Kempegowda International Airport (Bengaluru).
  • Public and Private Airlines:
    • Air India (national carrier) and private airlines like Indigo, SpiceJet, and Vistara dominate air travel.
  • Advantages of Airways:
    • Reduces travel time significantly.
    • Ideal for remote and inaccessible areas (Northeast India, Andaman & Nicobar Islands).
    • Essential for disaster relief and medical emergencies.
  • Challenges:
    • High operational costs.
    • Expensive fares compared to other modes.
    • Environmental concerns due to carbon emissions.

D. Waterways

  • The cheapest and most eco-friendly mode of transport, mainly used for bulky goods and trade.
  • Types of Waterways:
    • Inland Waterways: Rivers, canals, lakes, and backwaters (e.g., Ganga, Brahmaputra, and Godavari).
    • Oceanic Routes: Used for international trade via major ports.
  • Major Ports in India:
    • India has 12 major ports and over 200 minor ports.
    • Key ports: Mumbai, Chennai, Kolkata, Visakhapatnam, Cochin, and Kandla.

E. Pipelines

  • Used for transporting crude oil, petroleum, natural gas, and minerals.
  • Major Pipelines:
    • Hajira-Vijaipur-Jagdishpur (HVJ) pipeline: Carries natural gas.
    • Crude oil pipelines: Transport oil from oilfields to refineries.
  • Advantages of Pipelines:
    • Reduce transportation costs.
    • Minimize losses in transit.
    • Environmentally safe compared to road and rail transport.

Communication

Communication plays a vital role in economic and social development by ensuring information exchange and connectivity.

A. Personal and Mass Communication

  • Personal Communication: Includes postal services, telephone, and mobile networks.
  • Mass Communication: Includes radio, television, newspapers, magazines, and the internet.

    • Widespread use of social media platforms (Facebook, Twitter, WhatsApp).
    • Online news portals and streaming services.

B. International and Satellite Communication

  • India has developed a robust satellite communication system through INSAT and GSAT satellites.
  • Internet and mobile penetration have increased significantly, contributing to global connectivity.
  • Challenges: Digital divide between urban and rural areas.

International Trade

  • Trade is essential for economic growth as it allows the exchange of surplus goods and resources.
  • Exports and Imports:
    • India exports agricultural products, textiles, software, and pharmaceuticals.
    • Imports crude oil, machinery, electronic goods, and chemicals.
  • Special Economic Zones (SEZs): Promote trade and attract foreign investments.
  • Major Ports and Airports for Trade:
    • Jawaharlal Nehru Port (Mumbai) and Chennai Port handle large cargo volumes.
    • Indira Gandhi International Airport (Delhi) and Chhatrapati Shivaji Maharaj International Airport (Mumbai) handle air cargo.

Tourism as a Trade

  • Tourism contributes significantly to India’s GDP and employment.
  • Major Tourist Attractions:
    • Cultural Heritage: Taj Mahal, Jaipur forts, Khajuraho temples.
