Chapter 7 · Question 3
Explain the importance of waterways and airways.
Answer
Direct Answer
Waterways are suitable for cheap transport of heavy goods and international trade through ports. Airways are the fastest means of transport and are useful for long distances, difficult terrain, emergencies, and high-value goods, though they are costlier than other modes.
Simple Explanation
Waterways are the cheapest way to move heavy, bulky goods and handle international trade. Airways are the fastest, ideal for long distances, remote areas, emergencies, and high-value items, but they are the most expensive mode.
Exam-Ready Structure
Importance of waterways:
• Cheapest mode of transport: Fuel cost per tonne-kilometre is the lowest among all modes for moving heavy, bulky, and non-perishable goods.
• Suited for international trade: India's long coastline and major ports (Mumbai, Chennai, Kolkata, Kochi, Vishakhapatnam, Kandla) handle most of the country's overseas cargo — exports and imports of oil, ores, food grains, and manufactured goods.
• Inland waterways: Navigable rivers and canals (National Waterway 1 on the Ganga, NW 2 on the Brahmaputra, NW 3 in Kerala) provide low-cost freight movement within the country.
• Environmental benefit: Water transport has a lower carbon footprint compared to road and air transport.
Importance of airways:
• Fastest mode of transport: Covers long distances in hours that would take days by land or sea.
• Reaches difficult terrain: Essential for the north-eastern states, Jammu and Kashmir, Himachal Pradesh, and island territories (Andaman and Nicobar, Lakshadweep) where surface transport is limited or seasonal.
• Emergency and disaster response: Air ambulances, relief supply drops, and evacuation flights are critical during floods, earthquakes, and other calamities.
• High-value and perishable goods: Fresh flowers, fruits, seafood, electronics, and medicines are transported by air to preserve quality and reduce spoilage.
• Tourism and business connectivity: Airways link India to the world, supporting trade, investment, and the tourism industry.
Limitations: Airways are the costliest mode of transport and are not suitable for bulk, heavy goods. Both waterways and airways depend on good port and airport infrastructure.
Key Points
- Waterways are suitable for cheap transport of heavy goods and international trade through ports.
- Airways are the fastest means of transport and are useful for long distances, difficult terrain, emergencies, and high-value goods, though they are costlier than other modes.
