Lifelines of National Economy: Class 10 Geography · Chapter 7

Think about your breakfast this morning. The tea leaves may have been plucked in Assam, the wheat in your roti grown in Madhya Pradesh, and the cooking gas brought hundreds of kilometres by pipe. The news on your phone reached it through towers and cables, and the money your family paid moved through a bank in seconds. Nobody carried all this by hand. Behind an ordinary morning lies a web of roads, rails, pipes, river and sea routes, flight paths and wires.

This chapter looks at that web. It shows how goods, people and messages move within India and between India and the world, and why these networks are called the lifelines of the national economy.

7.1 Why we need transport

What we need is rarely made where we live. The places that grow or make a thing are its supply points; the places that want it are its demand points. Goods and services do not drift from one to the other on their own. Something must carry them, and that is the job of transport (परिवहन). Traders work in between: they buy where a thing is plentiful and sell where people want it, using transport to close the gap.

A bumper harvest is of little use if it rots for want of a road. So development needs two things together: making more goods and services, and moving them quickly and cheaply to where they are wanted. Good transport is not a reward that follows growth; it has to come first.

Goods and people travel over three parts of the Earth: land, water and air. Transport is grouped in the same three ways.

For most of history, trade and transport stayed within a small area, because a bullock cart or a sailing boat could cover only so much ground. Engines, steamships, aircraft and, later, electronic communication stretched that reach across continents. Today a shirt can be designed in one country, stitched in another and sold in a third. The world feels far smaller than it did a century ago.

Transport cannot do this alone. A truck is sent only after an order arrives, and the seller is paid only after the goods reach the buyer. Orders and payments travel by communication, goods travel by transport, and the exchange itself is trade. Each needs the other two (Fig. 7.1).

Look at what this web has done for India. A fishing town in Kerala and a village in Ladakh, with different languages and ways of life, now belong to one national market. Railways, airways and waterways move people and goods; newspapers, radio, TV, cinema and the internet move news and ideas. Every kind of trade, from the weekly haat to deals with distant countries, needs transport and communication networks that are dense and work well. In return, trade brings jobs, choice and comforts that earlier generations could not easily get.

7.2 Roadways

India has the second-largest road network in the world. Your textbook gives its length as about 62.16 lakh km in 2020–21. The Economic Survey 2025–26 lists about 65.9 lakh km for 2021–22 (provisional), counting every class of road from expressways to village tracks 11Economic Survey 2025–26, Statistical Appendix Table 1.28 (Ministry of Road Transport and Highways). Use the textbook's 62.16 lakh km in exam answers..

Roads came long before railways in India, and in many situations they still win, mainly because they are far easier to build and keep in repair. Here is why road transport keeps gaining ground on rail:

• Door to door. A truck loads at the factory gate and unloads at the shop, so little is spent on loading and unloading.
• Cheap for small loads. Moving a few people or a small load over a short distance costs less by road.
• A feeder to other modes. Roads link railway stations, airports and seaports with the places where people live and work.
• Cheaper to build. A kilometre of road costs much less than a kilometre of railway track.
• Fits rough country. A road can wind across broken, uneven land where laying a railway would be very hard.
• Climbs steep slopes. Roads can take much sharper gradients, so they cross high mountains such as the Himalayas (Fig. 7.2).

7.2.1 Classes of roads

Indian roads are grouped into six classes, according to what they can carry and which places they join (Fig. 7.3).

Golden Quadrilateral super highways. How do you cut the travel time between India's biggest cities? Build wide, fast roads between them. That was the aim of the Golden Quadrilateral (स्वर्णिम चतुर्भुज): a loop of multi-lane super highways, about 5,846 km long, around Delhi, Kolkata, Chennai and Mumbai 22Length as given in the Economic Survey 2006–07, which put the two corridors at about 7,300 km.. The National Highways Authority of India (NHAI) carries out the work. Two long corridors are part of the same project. The North–South corridor joins Srinagar (Jammu and Kashmir) with Kanniyakumari (Tamil Nadu), and the East–West corridor joins Silchar (Assam) with Porbandar (Gujarat). They cross at Jhansi (Fig. 7.4).

The backbone of the system is the network of National Highways (राष्ट्रीय राजमार्ग). In an atlas you will see them running both north–south and east–west, joining the farthest corners of the country to the state capitals and ports. India had about 1.46 lakh km of National Highways in December 2025, according to the Ministry of Road Transport and Highways.

Inside each state, the capital is tied to every district headquarters by State Highways. From each district headquarters, district roads fan out to the towns and other places of that district. The last link is made of other roads, mostly rural roads that join villages to towns. Since 2000, the Pradhan Mantri Gram Sadak Yojana (PMGSY) has been building such roads. Its aim: a bus or truck should reach every eligible village in any season and link it with a nearby town.

Along the northern and north-eastern frontiers, roads matter for defence as well as for daily life. Since 1960 the Border Roads Organisation (BRO), a Government of India body, has built and maintained these strategic border roads. In mountains and forests where travel was once very hard, they now carry soldiers, traders, tourists and villagers alike, and the economy of these areas has grown.

7.2.2 Metalled and unmetalled roads

A road's surface decides when it can be used. Roads with a hard top of cement concrete or bitumen (tar) are metalled roads (पक्की सड़कें): rain does not stop them, so they are all-weather roads. Unmetalled roads of earth or loose gravel turn to mud in the rains and often cannot be used for weeks.

7.3 Railways

Every day about two crore journeys begin on Indian trains: people going to work, on holiday, on pilgrimage or home for a festival. Meanwhile goods trains haul coal, grain and cement across the country. Railways are India's principal mode for both passengers and freight, above all over long distances. They have done more than move things. For over 150 years they have tied distant regions and cultures together, and by carrying raw materials and products cheaply they have helped farming and industry grow.

The Indian Railways is the country's largest public sector undertaking. Your textbook gives its route length as 67,956 km. By 2024–25 it had grown to about 69,440 route km, of which about 68,700 km was electrified. That year it carried about 729 crore passenger journeys and over 1,600 million tonnes of freight 33Economic Survey 2025–26, Statistical Appendix Table 1.26 (Ministry of Railways)..

To run such a large system, the railway is divided into zones, each with its own headquarters. Your textbook counts 17 zones. A new zone, South Coast Railway, with its headquarters at Visakhapatnam, began work on 1 June 2026, making 18.

7.3.1 Where the railways run

The railway map of India is uneven. Three kinds of factors shaped it: physiographic (the lie of the land), economic (where people, farms and industries are) and administrative. Some regions made building easy; others made it slow, costly or not worth it.

Along the west coast, the Konkan Railway (opened in 1998) runs through Maharashtra, Goa and Karnataka, between the Sahyadri and the sea. Rain-soaked slopes make it hard to run: landslides block the line, and some stretches of track have sunk. Even so, it has made travel and trade far easier along this busy economic belt.

Some of the railways' worst problems are caused by the public. Think of ticketless travel, theft and damage of railway property, and needless chain pulling that halts trains and delays thousands of passengers. That is a pity, because the railways now matter more to the national economy than all the other means of transport put together.

7.3.2 Rail gauges

The distance between the inner faces of the two rails is called the gauge (आमान). India built three gauges (Fig. 7.5): broad gauge (1.676 m), metre gauge (1.000 m) and narrow gauge (0.762 m or 0.610 m). A train cannot run from one gauge onto another, so goods once had to be shifted between wagons wherever two gauges met. That is why most metre and narrow gauge lines are being converted to broad gauge. In the textbook's table, broad gauge already made up about 94 per cent of the route length.

7.4 Pipelines

Imagine moving crude oil to a refinery far inland by tanker trucks: thousands of trips, spills and delays. A pipeline does the same job quietly, day and night. That is why refineries could be built far from the coast, at Barauni, Mathura and Panipat, along with gas-based fertiliser plants deep inland. A pipeline costs a lot to lay, but once it is in place, running it is cheap. And because the oil never changes carrier on the way, there are no trans-shipment losses or delays.

Pipelines are a recent addition to India's transport network. Earlier they were laid mainly to supply water to towns and factories. Today they move crude oil and natural gas out of the fields, and petroleum products onward. They feed refineries, fertiliser factories and large thermal power stations. Even solids can travel by pipe once they are crushed and mixed with water into a slurry.

India has three important pipeline networks (Fig. 7.6):

1. Upper Assam to Kanpur. It starts at the oil field of upper Assam and passes Guwahati, Barauni and Prayagraj on the way to Kanpur in Uttar Pradesh. Branches run from Barauni to Haldia through Rajbandh, from Rajbandh to Maurigram, and from Guwahati to Siliguri.
2. Salaya to Jalandhar. It starts at Salaya on the Gujarat coast and passes Viramgam, Mathura, Delhi and Sonipat on the way to Jalandhar in Punjab. Branches reach Koyali (near Vadodara), Chakshu and other places.
3. Hazira–Vijaipur–Jagdishpur (HVJ). India's first cross-country gas pipeline, about 1,700 km long. It linked the Mumbai High and Bassein gas fields with fertiliser, power and industrial plants in western and northern India.

Your textbook says India's cross-country gas pipelines grew from 1,700 km to 18,500 km. By 31 December 2025 about 27,400 km of natural gas pipelines were working, with about 8,500 km more being built 44Petroleum and Natural Gas Regulatory Board, Natural Gas Pipeline Networks in India, December 2025: 27,427 km operational and 8,489 km under construction..

7.5 Waterways

A barge uses far less fuel per tonne than a truck, so water transport is the cheapest mode and the gentlest on the environment. It is slow, but ideal for heavy, bulky goods. This is nothing new for India: since ancient times its sailors and merchants carried goods and ideas across the seas.

India has about 14,500 km of navigable inland waterways. The government wants river and canal transport to grow into a cheap, clean partner to rail and road. So the National Waterways Act, 2016 declared 111 National Waterways (राष्ट्रीय जलमार्ग), including the five declared earlier 55Source quoted in the textbook: Annual Report 2022–23, Ministry of Ports, Shipping and Waterways.. The first five are compared in Fig. 7.7.

• NW-1: the Ganga between Prayagraj and Haldia (1,620 km).
• NW-2: the Brahmaputra between Sadiya and Dhubri (891 km).
• NW-3: the West Coast Canal in Kerala: Kottapuram–Kollam, with the Udyogamandal and Champakkara canals (205 km).
• NW-4: stretches of the Godavari and Krishna, with the Kakinada–Puducherry canals (1,078 km).
• NW-5: stretches of the Brahmani and Matai rivers, the delta channels of the Mahanadi and Brahmani, and the East Coast Canal (588 km).

Several other inland waterways also carry a lot of traffic. They include the Mandovi, Zuari and Cumberjua in Goa, the Sunderbans in West Bengal, the Barak in Assam and the backwaters of Kerala. In the north-eastern states, boats on the rivers are part of everyday travel.

Cargo on the National Waterways has grown quickly in recent years (Table 7.4).

For trade with other countries, the sea matters even more. Your textbook notes that about 95 per cent of India's trade by volume, and about 68 per cent by value, moves by sea.

7.5.1 Major sea ports

India's coastline is about 11,098.81 km long. Along it lie 12 major ports and about 200 notified non-major ports (minor and intermediate ports). The major ports come under the central government; the non-major ports come under the coastal states (Fig. 7.8).

Partition in 1947 put Karachi, the port that had served north-western India, inside Pakistan, and Mumbai was left overloaded. The answer was Deendayal Port (Kandla) in Kachchh, the first port developed after Independence. It is a tidal port. Its hinterland (पृष्ठप्रदेश) is the land whose goods pass through it. Here that is a rich belt of farms and industries across Jammu and Kashmir, Himachal Pradesh, Punjab, Haryana, Rajasthan and Gujarat.

The other west coast ports, from north to south:

• Mumbai (Maharashtra): a roomy natural harbour, well sheltered from the sea; your textbook calls it India's biggest port.
• Jawaharlal Nehru Port (Navi Mumbai): built across the harbour to ease the crowding at Mumbai, and a hub port for the region.
• Mormugao (Goa): ships out more iron ore than any other Indian port; the textbook puts its share at about half of India's iron ore exports.
• New Mangalore (Karnataka): the outlet for iron ore concentrates from the Kudremukh mines.
• Kochi (Kerala): in the far south-west, a natural harbour where a lagoon opens to the sea.

The east coast ports, from south to north:

• V.O. Chidambaranar (Tuticorin, Tamil Nadu): in the far south-east; a natural harbour with a rich hinterland, handling varied cargo for Sri Lanka, the Maldives and India's own coastal regions.
• Chennai (Tamil Nadu): one of India's oldest artificial (man-made) harbours. The textbook ranks it second only to Mumbai in trade and cargo.
• Kamarajar Port (Ennore) (Tamil Nadu): just north of Chennai.
• Visakhapatnam (Andhra Pradesh): the deepest landlocked port, sheltered from the open sea; first planned for exporting iron ore.
• Paradip (Odisha): specialises in exporting iron ore.

Far up the Hooghly lies Syama Prasad Mookerjee Port, Kolkata, a river port well inland from the sea. The river drops silt and the tides stir it, so dredgers must keep deepening the channel for ships. The effort pays: the port serves the vast, rich Ganga–Brahmaputra basin. To ease its load, a subsidiary port was developed downstream at Haldia.

Which ports are busiest today? In 2025–26 the 12 major ports together handled about 915 million tonnes of cargo. Deendayal and Paradip handled the most, over a third of it between them, while Mumbai came fifth (Fig. 7.9). For exam answers, follow the textbook: Mumbai is described as the biggest port, with its spacious natural harbour. By cargo weight, the bulk-cargo ports now lead.

7.6 Airways

When speed matters most, people fly: air travel is the fastest mode, as well as the most comfortable and prestigious. Nothing on the ground stands in its way, so a plane crosses snowy ranges, deserts, forests and oceans as easily as plains.

This matters most in the north-eastern states (Fig. 7.10). There, large rivers, deeply cut hills, thick forests, frequent floods and long international borders make roads slow and railways hard to build. Flights and helicopters have made the region far easier to reach.

Pawan Hans Helicopters Ltd flies helicopters for the Oil and Natural Gas Corporation (ONGC) to its offshore oil platforms. It also serves hard-to-reach places such as the north-eastern states and the interior of Jammu and Kashmir, Himachal Pradesh and Uttarakhand.

Flying is no longer only for the rich. India had 165 operational airports on 15 July 2026, up from 74 in 2014, and Indian airports handled about 41 crore passengers in 2024–25 66Airports: PIB backgrounder on the Modified UDAN scheme, July 2026. Passengers: Economic Survey 2025–26, Statistical Appendix Table 1.29 (Ministry of Civil Aviation)..

7.7 Communication

A video call to a cousin in Dubai, a message to a classmate, the evening news on TV: every day you communicate over long distances without leaving home. People have always sent messages, by drums, runners, smoke signals and letters, but change has never been as fast as in modern times.

Communication is of two kinds (Fig. 7.12). Personal communication is between individuals: letters, phone calls and messages. Mass communication (जनसंचार) reaches huge numbers of people at once, through television, radio, the press and films.

Letters do not all travel the same way. Cards and envelopes are first-class mail: they are flown between stations, so they move by land and air. Book packets, registered newspapers and periodicals are second-class mail, carried by surface over land and water. Behind this is the biggest postal network on Earth, handling parcels as well as letters. In big cities, six special mail channels speed up delivery: Rajdhani, Metro, Green, Business, Bulk Mail and Periodical.

India's telecom network is among the biggest in Asia. Your textbook notes that STD (long-distance) telephone service reached more than two-thirds of villages, at a uniform rate across India, because space technology was joined with communication technology. Mobile phones have since carried this much further. At the end of March 2026, India had about 133 crore telephone connections and 109 crore internet subscriptions. Rural areas still lag, with only about 60 telephone connections per 100 people 77TRAI, Indian Telecom Services Yearly Performance Indicators 2025–26, released 5 October 2026: 1,330.58 million telephone and 1,092.79 million internet subscribers; rural tele-density 60.46 per cent..

Radio and television do two jobs: they entertain, and they tell people about national programmes and policies. Akashvani (All India Radio) has stations across the country whose programmes, in national, regional and local languages, serve farmers, students, children and many other listeners. Doordarshan, the national television channel, reaches the whole country through a land-based transmitter network that ranks among the world's biggest. It shows entertainment, education and sports for viewers of every age.

Films are big in India: the country makes more feature films than any other, besides short films and video films. Every film, Indian or foreign, needs a certificate from the Central Board of Film Certification (CBFC) before it is shown. The press is just as varied. Newspapers and periodicals, some daily and others weekly or monthly, appear in about 100 languages and dialects; Hindi has the most titles, then English, then Urdu.

7.8 International trade

When goods are swapped for money or other goods, whether between people, states or countries, we call it trade; the place where this happens is a market. Buying and selling inside a city, town or village is local trade. Trade that crosses from one state into another is state-level trade. Trade that crosses a national border is international trade (अंतर्राष्ट्रीय व्यापार), and it may go by sea, air or land.

Resources are tied to places: no country has every mineral, crop and skill it needs. So no country can do without international trade. How fast a country's international trade is growing says a lot about its prosperity, which is why it is called the economic barometer of a country.

Trade has two parts. Exports are goods and services a country sells abroad; imports are those it buys from abroad. The balance of trade (व्यापार संतुलन) is the difference between the value of its exports and the value of its imports (Fig. 7.13).

• Favourable balance of trade: exports are worth more than imports.
• Unfavourable balance of trade: imports are worth more than exports.

India trades with all the major trading blocs and with every region of the world. The textbook lists its exports as gems and jewellery, chemicals and related products, and agricultural and allied products, among others. Its imports include crude petroleum and petroleum products, gems and jewellery, chemicals, base metals, electronic items, machinery, and agricultural and allied products. Gems and jewellery appear on both lists: India buys rough diamonds and gold, and sells cut and polished stones and finished jewellery.

India has also become a software giant, earning large amounts of foreign exchange by exporting information technology and other services. In 2025–26, services exports were estimated at about US$ 418 billion, almost as much as goods exports (Ministry of Commerce estimate, April 2026).

7.9 Tourism as a trade

When a family from Germany pays for a houseboat holiday in Kerala, money comes into India from abroad for a service sold here. Tourism is therefore a kind of trade. Over the last twenty years, tourism in India has boomed. Government initiatives, new airports, roads and hotels, and campaigns selling India abroad have all played a part.

To boost it further, the government has started several schemes. They include Swadesh Darshan 2.0, the Vibrant Villages Programme, PRASHAD (Pilgrimage Rejuvenation and Spiritual Heritage Augmentation Drive) and Paryatan Mitra.

Tourism does more than earn money (Fig. 7.14). It creates jobs in hotels, transport and guiding, and it supports local handicrafts and cultural traditions. It builds national integration as people from different regions meet, and it helps people abroad understand India's culture and heritage. Foreign tourists come to India for heritage, eco, adventure, cultural, medical and business tourism.

In 2025, India received about 91.5 lakh foreign tourists, fewer than the 99.5 lakh of 2024, and earned about US$ 31.7 billion in foreign exchange from tourism 88Ministry of Tourism, India Tourism Data Compendium 2026: foreign tourist arrivals 91.49 lakh in 2025 and 99.52 lakh in 2024; foreign exchange earnings US$ 31.69 billion in 2025.. Almost every state has something to offer, from deserts and beaches to hill stations and temples, so the scope for growth is huge.
