Lifelines of National Economy Class 10 Notes Social Science Geography Chapter 7
Means of transport and communication—lifelines of our national economy:
They help in—
- increasing cooperation and assistance between countries;
- easy movement of goods and material between countries;
- trade and commerce within the country;
- reducing distances thus bringing the world closer;
- both production and distribution of goods; and
- movement of large number of people and over long distances.
Importance of road transport vis-a-vis rail transport—
- Construction cost of roads is much lower than that of railway lines.
- Roads can traverse comparatively more dissected and undulating topography.
- Roads can negotiate higher gradients of slopes and as such can traverse mountains such as the Himalayas.
- Road transport is economical in transportation of few persons and relatively smaller amount of goods over short distances.
- It also provides door-to-door service, thus the cost of loading and unloading is much lower.
- Road transport is also used as a feeder to other modes of transport.
Six classes of roads in India according to their capacity:
- Golden Quadrilateral Super Highways: It’s a major road development project linking Delhi- Kolkata-Chennai-Mumbai and Delhi by six-lane Super Highways.
- The North-South corridors linking Srinagar (Jammu & Kashmir) and Kanyakumari (Tamil Nadu), and East-West Corridor connecting Silcher (Assam) and Porbander (Gujarat) are part of this project. ‘
- They are made to reduce the time and distance between the mega cities of India.
National Highways link all Major cities of extreme parts of the country. These are the primary road systems and are maintained by the Central Public Works Department (CPWD). The National Highway 7 between Varanasi and Kanyakumari is the longest highway of India.
- State Highways: Roads linking a state capital with different district headquarters. These roads are constructed and maintained by State Public Works Department in State and Union Territories.
- District Roads: These roads connect the district headquarters with other places of the district. These roads are maintained by the Zila Parishad.
- Other Roads: Rural roads, which link rural areas and villages with towns, are classified under this category. Under the Pradhan Mantri Grameen Sadak Yojana scheme special provisions are made so that every village in the country is linked to a major town in the country by an all season motorable road.
- Border Roads: Border Roads Organisation constructs and maintains roads in the bordering areas of the country. These roads are of strategic importance in the northern and northeastern border areas.
Importance of Railways in India:
They are the principal mode of transportation for freight and passengers in India. Railways also make it possible to conduct different activities like business, sightseeing, and pilgrimage along with transportation of goods over longer distances. Indian Railways plays a role of national integration. Railways in India bind the economic life of the country as well as accelerate the development of the industry and agriculture.
Factors which influence the distribution pattern of Railway network in India:
The distribution pattern of the Railway network in the country has been largely influenced by physiographic, economic and administrative factors. The density railway network is high in the northern plains because they are vast level land, have high population density and rich agricultural resources. In the hilly terrains of the peninsular region, railway tracts are laid through low hills, gaps or tunnels therefore it difficult to construct railway lines. The Himalayan mountainous regions too are unfavorable for the construction of railway lines due to high relief, sparse population and lack of economic opportunities. It was difficult to lay railway lines on the sandy plain of western Rajasthan, swamps of Gujarat, forested tracks of Madhya Pradesh, Chhattisgarh, Odisha and Jharkhand.
Importance of Pipelines in India:
In the past, these were used to transport water to cities and industries. Now, these are used for transporting crude oil, petroleum products and natural gas from oil and natural gas fields to refineries, fertilizer factories and big thermal power plants. Solids can also be transported through a pipeline when converted into slurry. Because of pipelines refineries like Barauni, Mathura, Panipat and gas based fertilizer plants could be located in the interiors of India. Initial cost of laying pipelines is high but subsequent running costs are minimal. It rules out trans-shipment (during transportation) losses or delays.
Three important networks of pipeline transportation in the country:
- From oil field in upper Assam to Kanpur (Uttar Pradesh).
- From Salaya in Gujarat to Jalandhar in Punjab.
- Gas pipeline from Hazira in Gujarat connects Jagdishpur in Uttar Pradesh,
Importance of water transport:
Waterways are the cheapest means of transport. They are most suitable for carrying heavy and bulky goods. It is a fuel-efficient and environment friendly mode.
The National Waterways by the Government
- The Ganga river between Allahabad and Haldia (1620 km)-N.W. No.1
- The Brahmaputra river between Sadiya and Dhubri (891 km)-N.W. No.2
- The West-Coast Canal in Kerala (Kottapurma-Komman, Udyogamandal and Champakkara canals-205 km)-N.W. No.3
