Exercise 20.1India: People and Economy — Transport and Communication
Q1
What is the transport network in India? Describe the road and railway network.
Solution
India's Transport Network:
• India has one of the largest transport networks in the world — reflecting its size, population, and diversity.
• A good transport network is essential for: Moving agricultural produce to markets, distributing industrial goods, enabling migration, national integration.
Road Transport:
• India has one of the world's largest road networks — about 6.5 million km (including rural roads).
• Road transport carries about 90% of passenger traffic and 65% of freight.
Classification of Roads:
1. Expressways: Modern, high-speed, access-controlled highways — under NHAI.
2. National Highways (NH): Major roads connecting states — maintained by NHAI (National Highways Authority of India); about 1.45 lakh km.
3. State Highways: Secondary roads within states — maintained by state PWDs.
4. District Roads: Connecting district headquarters to towns and villages.
5. Village Roads (Rural Roads): Connecting villages — Pradhan Mantri Gram Sadak Yojana (PMGSY) has constructed lakhs of km.
Key National Highways:
• NH 44 (formerly NH 7): Srinagar to Kanniyakumari — India's longest NH (3,745 km).
• Golden Quadrilateral: Delhi–Mumbai–Chennai–Kolkata — high-speed corridor.
• North-South and East-West Corridors: Extending the GQ.
Railway Transport:
• Indian Railways is one of the world's largest railway networks — about 68,000 km of route.
• About 13,000 passenger trains and 8,000 freight trains daily.
• Organised into 17 zones — headquartered in major cities.
• Indian Railways carries about 8 billion passengers and 1.5 billion tonnes of freight annually.
Gauge:
• Broad gauge (1,676 mm): 90%+ of network — most passenger and freight lines.
• Metre gauge (1,000 mm): Being converted to broad gauge.
• Narrow gauge: Some hilly railways (Darjeeling Himalayan, Nilgiri, Matheran).
Key Developments:
• Dedicated Freight Corridors: Eastern (Ludhiana–Dankuni) and Western (JNPT–Dadri) DFCs — separating freight trains from passenger trains for speed.
• High-speed rail: Ahmedabad–Mumbai bullet train project (Shinkansen technology).
• Metro rail: Delhi, Mumbai, Bengaluru, Chennai, Hyderabad, Kolkata — expanding urban metro networks.
Q2
Describe the waterways and airways in India. What is the significance of ports?
Solution
Inland Waterways:
• India has about 14,500 km of navigable inland waterways — rivers, canals, backwaters, creeks.
• Inland Waterways Authority of India (IWAI) develops and maintains National Waterways.
• Major National Waterways:
- NW-1: Ganga–Bhagirathi–Hooghly system (Allahabad/Prayagraj to Haldia, 1,620 km) — most important.
- NW-2: Brahmaputra (Sadiya to Dhubri, 891 km) — Assam.
- NW-3: West Coast Canal + Champakara + Udyogamandal canals in Kerala (205 km).
- NW-4: Kakinada to Pondicherry canals (1,095 km).
• Advantages of water transport: Cheapest mode; eco-friendly; reduces road congestion.
• Limitations: Seasonal (rivers dry up in summer); slow; limited to navigable rivers.
Coastal Shipping:
• India has a 7,517 km coastline and over 200 ports.
• Coastal shipping moves goods between Indian ports — coal from Odisha to Tamil Nadu power plants, for example.
• Cheaper and less polluting than road transport for coastal routes.
Major Ports (12 Major Ports):
• Deendayal (Kandla, Gujarat): Largest port by cargo handled — major gateway for northwest India; oil, fertilisers, chemicals.
• Mumbai (JNPT — Jawaharlal Nehru Port): India's busiest container port — handles most of India's container traffic.
• Chennai: Major port for automobiles (Hyundai, Ford export through Chennai); containers.
• Vishakhapatnam: Largest deep-water port — iron ore exports, naval base.
• Kolkata (with Haldia): Major port for northeastern India; coal, jute, foodgrains.
• Paradip (Odisha): Major port for mineral exports.
• Marmagao (Goa): Iron ore exports (historically India's largest).
Air Transport:
• India has about 150 airports — operated by AAI (Airports Authority of India).
• Major international airports: Delhi (Indira Gandhi International — world's 10th busiest), Mumbai (CSIA), Bengaluru, Chennai, Hyderabad, Kolkata.
• Domestic aviation: India is the world's third-largest domestic aviation market — dominated by IndiGo, Air India.
• UDAN (Ude Desh Ka Aam Nagrik) scheme: Connecting smaller towns by subsidised air service.
• Air cargo: Growing rapidly for high-value goods (pharmaceuticals, electronics, fresh produce).
Q3
What are the major communication developments in India? What is the digital revolution and its impact?
Solution
Communication in India:
Pre-digital Communication:
• India Posts: One of the world's largest postal networks — 1.55 lakh post offices (2023); serves rural areas. Speed Post, Money Order, rural banking through post offices.
• Telecom: BSNL and MTNL (government); later private operators.
Telecom Revolution:
• India has the world's second-largest telecom subscriber base — about 1.2 billion subscribers.
• Mobile phone penetration is transforming rural India — information, banking, entertainment.
• Jio Effect (2016): Reliance Jio's entry with cheap 4G data caused a revolution — data costs in India became the world's lowest; data usage exploded.
Digital India:
• Digital India programme (launched 2015): Aims to transform India into a digitally empowered knowledge economy.
• Key pillars: Broadband highways, universal mobile connectivity, public internet access, e-governance, digital literacy.
• BharatNet: Optical fibre network connecting all gram panchayats — rural broadband.
Key Digital Developments:
1. UPI (Unified Payments Interface): India's real-time digital payment system — processes billions of transactions monthly. India leads the world in real-time digital payments.
2. Aadhaar: Biometric identity for 1.3 billion people — enables direct benefit transfers, reducing leakages in welfare schemes.
3. E-governance: Online applications for services — passports, driving licences, land records, tax filing.
4. EdTech: Online education platforms — Byju's, Unacademy; SWAYAM (government MOOCs); PM e-Vidya.
5. CoWIN: COVID-19 vaccination management — over 2 billion vaccine doses tracked.
6. Digital health (ABHA): Ayushman Bharat Digital Mission — digital health ID for every Indian.
Digital Divide:
• Urban India is digitally connected; rural India, especially women and elderly, lags.
• States with low literacy and poor infrastructure (Bihar, UP) have lower digital penetration.
• BharatNet and PMGDISHA (digital literacy) aim to bridge this gap.
Satellite Communication:
• ISRO: India's space programme has launched communication satellites (INSAT) and navigation satellites (NavIC/IRNSS).
• INSAT satellites support: TV broadcasting, weather forecasting, disaster warning, remote sensing.
