LIFELINES OF NATIONAL ECONOMY CLASS X GEOGRAPHY CHAPTER 7 NOTE AND EXERCISE

7: LIFELINES OF NATIONAL ECONOMY


1. INTRODUCTION

  • We use materials and services in daily life — some are available locally, others come from far-off places.
  • Goods and services do not move on their own from supply locations (production centres) to demand locations (consumption centres). This movement requires transport.
  • People who help goods reach consumers through transportation are called traders.
  • Pace of development of a country depends on:
    1. Production of goods and services
    2. Efficient movement of these goods and services over space
  • Movement of goods/services takes place over three domains of the earth:
    • Land
    • Water
    • Air
  • Based on these domains, transport is classified as land, water, and air transport.
  • Transport, communication, and trade are complementary to each other — a dense and efficient network of transport and communication is a prerequisite for local, national, and global trade.
  • Hence, transport, communication, and trade are called the "Lifelines of the National Economy."

2. ROADWAYS

Importance

  • India has the second largest road network in the world — about 62.16 lakh km (2020–21).
  • Roadways preceded railways in India and still have an edge over rail transport.

Merits of Roads over Railways

Reason

Explanation

(a) Lower construction cost

Roads are cheaper to build than railway lines

(b) Suitable for varied terrain

Can traverse dissected and undulating topography

(c) Negotiate steep slopes

Can cross mountains like the Himalayas

(d) Economical for short distance

Best for transporting few persons/small goods over short distances

(e) Door-to-door service

Lower loading/unloading costs

(f) Acts as a feeder

Links railway stations, airports, and seaports with other transport modes

Classification of Roads (Six Classes)

  1. Golden Quadrilateral Super Highways
    • Six-lane superhighways connecting Delhi–Kolkata–Chennai–Mumbai.
    • North-South Corridor: links Srinagar (J&K) to Kanniyakumari (Tamil Nadu).
    • East-West Corridor: connects Silchar (Assam) to Porbandar (Gujarat).
    • Objective: reduce time and distance between mega cities.
    • Implemented by the National Highways Authority of India (NHAI).
  2. National Highways (NH)
    • Link extreme parts of the country.
    • Primary road system running North-South and East-West.
  3. State Highways
    • Roads linking a state capital with various district headquarters.
  4. District Roads
    • Connect district headquarters with other places in the district.
  5. Other Roads
    • Rural roads linking villages and rural areas with towns.
    • Boosted under the Pradhan Mantri Grameen Sadak Yojana — aims to connect every village to a town by an all-season motorable road.
  6. Border Roads
    • Constructed and maintained by the Border Roads Organisation (BRO), a Government of India undertaking, established in 1960.
    • Built for strategic importance in northern and north-eastern border areas.
    • Improved accessibility in difficult terrain and aided economic development.
    • Example: Atal Tunnel (9.02 km) — world's longest highway tunnel, connects Manali to Lahaul-Spiti valley, built in the Pir Panjal range at 3,000 m MSL.

Roads by Material Used

  • Metalled Roads: made of cement, concrete, or bitumen; all-weather roads.
  • Unmetalled Roads: go out of use during the rainy season.

3. RAILWAYS

Importance

  • Principal mode of transport for freight and passengers.
  • Enables business, sightseeing, pilgrimage, and long-distance transport of goods.
  • Has been a great integrating force for over 150 years.
  • Binds the economic life of the country and accelerates industrial and agricultural development.
  • Indian Railways is the largest public sector undertaking in India.
  • First train ran from Mumbai to Thane in 1853, covering 34 km.
  • Indian Railway is reorganised into 17 zones.

Factors Influencing Distribution of Railway Network

Region

Effect

Northern Plains

Level land, high population density, rich agriculture most favourable for railway growth (though rivers required many bridges)

Hilly/Peninsular region

Tracks laid through low hills, gaps, or tunnels

Himalayan region

High relief, sparse population unfavourable

Western Rajasthan (sandy), Gujarat (swampy), MP/Chhattisgarh/Odisha/Jharkhand (forested)

Difficult to lay lines

Sahyadri (Western Ghats)

Crossed only through gaps/passes (Ghats)

West Coast

Konkan Railway facilitates movement of goods/passengers, though it faces problems like track sinking and landslides

2. Answer in about 30 words

(i) State any three merits of roadways. 

Road construction costs are low; roads can traverse hilly and dissected terrain as well as steep gradients; they provide door-to-door service, lowering loading and unloading costs; and they act as a feeder to other modes of transport like railways, airports, and ports.

(ii) Where and why is rail transport the most convenient means of transportation? 

Rail transport is most convenient on the level Northern Plains, where vast plains, high population density, and rich agricultural resources make railway construction easy and profitable, enabling movement of both passengers and bulky goods over long distances.

(iii) What is the significance of the border roads? 

Border roads, built and maintained by the Border Roads Organisation (established 1960), improve accessibility in the difficult terrains of northern and north-eastern border areas, help in the economic development of these regions, and are of great strategic importance for national defence.

(iv) What is meant by trade? What is the difference between international and local trade? 

Trade is the exchange of goods among people, states, and countries. Local trade is carried out within cities, towns, and villages, while international trade takes place between two or more countries through sea, air, or land routes, and reflects a nation's economic prosperity.


3. Answer in about 120 words

(i) Why are the means of transportation and communication called the lifelines of a nation and its economy?

Goods and services do not move on their own from places of production to places of consumption — this movement requires an efficient transport network. Similarly, communication allows the exchange of information without physical movement of people. Together, transport and communication enable trade at local, national, and international levels, connecting producers with consumers across the country and the world. Railways, roadways, airways, and waterways move raw materials to industries and finished goods to markets, while postal services, telecommunication, radio, television, and the internet spread information and awareness rapidly. This integration accelerates industrial and agricultural development, promotes national integration despite India's vast size and diversity, and strengthens the country's international trade. Since a nation's economic progress depends entirely on this dense, efficient network functioning smoothly, transport, communication, and trade are rightly called the "lifelines of the national economy."

(ii) Write a note on the changing nature of the international trade in the last fifteen years.

International trade in India has changed remarkably in recent years. Traditionally dependent on the export of primary and agricultural products, India's trade basket has diversified to include gems and jewellery, chemicals, machinery, electronic items, and agricultural products, while imports now include petroleum crude, base metals, and industrial machinery. The most significant change has been India's emergence as a global leader in information technology and software services, earning substantial foreign exchange through IT exports. Trade is no longer restricted to the exchange of physical goods; it has expanded to services such as software, business process outsourcing, and tourism. Tourism itself has grown into a major trade activity, promoted through schemes like Swadesh Darshan 2.0 and PRASHAD, attracting foreign tourists for heritage, eco, adventure, medical, and business purposes. India today maintains trade relations with all major trading blocks and geographical regions, reflecting deeper integration with the global economy.
