What are ‘Lifelines of National Economy’?

"Lifelines of National Economy" refers to the essential infrastructure that supports a country's economic activities.

Lifelines Of National Economy Class 10 Notes

A nation's development depends on producing and moving goods and services. Modern transport and communication systems transform the world into a global village. India relies on these systems for its national economy. Below are the Class 10th Geography Chapter 7 Notes:

Transport

Movement of goods and services occurs across land, water, and air. Transport modes are classified based on these domains.

Roadways

India possesses a vast road network, over 54.7 lakh km long. Road transport offers several advantages over railways.

Advantages of Road Transport:

  • Road construction costs less than railway lines.

  • Roads reach more difficult geographic areas.

  • They can handle steeper slopes and build across mountains.

  • Road transport is economical for short distances.

  • It provides convenient door-to-door service.

  • Roads connect railway stations, airports, and seaports.

Classification of Roads:

  • Golden Quadrilateral Super Highways: Connects Delhi, Kolkata, Chennai, and Mumbai. NHAI implements these projects.

  • National Highways: Trunk roads maintained by the CPWD. NH-1 runs between Delhi and Amritsar.

  • State Highways: Link state capitals with district headquarters. Maintained by the State PWD.

  • District Roads: Connect district headquarters to other district places. Maintained by Zila Parishad.

  • Other Roads: Rural roads linking villages to towns. Promoted under Pradhan Mantri Grameen Sadak Yojana.

  • Border Roads: Constructed and maintained by the Border Roads Organisation (established 1960) in border areas for strategic reasons.

  • Road Types by Material:

  • Metalled Roads: Made of cement, concrete, or bitumen. These are all-weather roads.

  • Unmetalled Roads: Become unusable during the rainy season.

Railways

Railways are a primary transport mode for heavy and bulky goods over long and short distances in India. They are vital to the Indian economy. However, challenges exist.

Problems with Rail Transport:

  • Requires bridge construction over wide river beds.

  • Tracks in peninsular hilly regions need low hills, gaps, or tunnels.

  • Himalayan regions are difficult due to high elevation, sparse population, and limited economic scope.

  • Laying railway lines on sandy plains is hard.

Pipelines

Pipeline networks use pipes, usually underground, to move fluids. They transport crude oil, petroleum products, natural gas, and water. Solids become slurry for pipeline transport.

  • Key Pipeline Networks:

  1. Oil fields in Upper Assam to Kanpur (Uttar Pradesh).

  2. Salaya in Gujarat to Jalandhar in Punjab.

  3. Hazira in Gujarat to Jagdishpur in Uttar Pradesh.

Waterways

Waterways offer the cheapest transport. They suit heavy and bulky goods best. This mode is fuel-efficient and eco-friendly.

National Waterways (NW):

  • NW No. 1: Ganga River between Allahabad and Haldia (1620 km).

  • NW No. 2: Brahmaputra River between Sadiya and Dhubri (891 km).

  • NW No. 3: West-Coast Canal in Kerala (Kottapurma-Kollam, Udyogamandal, Champakkara canals - 205 km).

  • NW No. 4: Specific stretches of Godavari and Krishna rivers, with Kakinada-Puducherry canal stretch (1078 km).

  • NW No. 5: Specific stretches of Brahmani River, Matai River, Mahanadi, and Brahmani delta channels, and East Coast Canal (588 km).

  • Inland waterways include Mandavi, Zuari, Cumberjua, Sunderbans, Barak, and Kerala's backwaters.

Major Sea Ports

India's foreign trade relies on its ports. There are 12 major and 200 non-major (minor/intermediate) ports.

Notable Major Ports:

  • Kandla (Deendayal Port): First port developed after independence, in Kachchh.

  • Mumbai: Biggest port with a natural, sheltered harbor.

  • Marmagao (Goa): Premier iron ore exporting port.

  • Kolkata: Inland riverine port.

  • Haldia: Subsidiary port to ease pressure on Kolkata.

Airways

Air travel is the fastest, most comfortable, and prestigious transport mode. It easily reaches challenging areas like high mountains and deserts. Air transport was nationalized in 1953. Air India provides domestic and international services. Pawan Hans Helicopters Ltd. offers services for offshore operations and difficult terrains. However, air travel remains expensive for many.
