There are three types of economic activities. These are:
1. Primary Activities: Connected with extraction and production of natural resources like forestry, agriculture, mining, animal husbandry, etc.
2. Secondary Activities: Connected with processing and manufacturing of primary goods into finished goods. They get raw material from the Primary sector. For e.g. Iron ore into tools & machines, sugar cane into sugar, etc.
3. Tertiary Activities: Provides support to Primary and Secondary sectors through services, e.g. transportation, banking, tourism, etc.

Lifelines of National Economy:
• Transport plays an important role in the economy.
• Because of transport raw materials reach the factory and finished products reach to the consumer.
• The pace of development of a country depends upon the production of goods and services as well as their movement over space.
• Therefore, efficient means of transport are pre-requisites for fast development.
• Apart from transport, the ease and mode of communications, like telephone and internet makes seamless flow of information possible.
• Today, India is well-linked with the rest of the world despite its vast size, diversity and linguistic and socio-cultural plurality.
• Railways, airways, waterways, newspapers, radio, television, cinema and internet, etc. have been contributing to its socio-economic progress in many ways.
• The trades from local to international levels have added to the vitality of its economy.
• It has enriched our life and added substantially to growing amenities and facilities for the comforts of life.

 

ROADWAYS:

• India has one of the largest road networks in the world, aggregating to about 2.3 million km at present.
• In India, roadways have preceded railways.
• They still have an edge over railways in view of the ease with which they can be built and maintained.
• The growing importance of road transport against the transport is rooted in the following reasons:
(a) Construction cost of roads is much lower than that of railway lines.
(b) Roads can pass through comparatively more dissected and undulating topography.
(c) Roads can negotiate higher gradients of slopes and as such can traverse mountains such as the Himalayas.
(d) Road transport is economical in transportation of few persons and relatively smaller amount of goods over short distances.
(e) It also provides door-to-door service, thus the cost of loading and unloading is much lower.
(f) Road transport is also used as a feeder to other modes of transport such as they provide a link between railway stations, air and sea ports.

In India, roads are classified in the following six classes according to their capacity:

(a) Golden Quadrilateral:

• The government has launched 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.
• The major objective of these super highways is to reduce the time and distance between the mega cities of India.
• These highway projects are being implemented by the National Highway Authority of India (NHAI).

(b) National Highways:
• National highways link extreme parts of the country.
• These are the primary road systems and are laid and maintained by the Central Public Works Department (CPWD).
• A number of major national highways run in north-south and east-west directions.

(c) State Highways:
• Roads linking a state capital with different district headquarters are known as state highways.
• These roads are constructed and maintained by the state Public Works Department (PWD) in state and union territories.

(d) District Roads:
• These roads connect the district headquarters with other places of the district.
• These roads are maintained by the Zila Parishad.

(e) Other Roads:
• Rural roads, which link rural areas and villages with towns, are classified under this category.
• These roads received special momentum under the Pradhan Mantri Grameen Sadak Yojana.
• Under this 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.

(f) Border Roads:
• Apart from these, Border Roads Organization a government of India undertaking constructs and maintains roads in the bordering areas of the country.
• This organization was established in 1960 for the development of the roads of strategic importance in the northern and northeastern border areas.
• These roads have improved accessibility in areas of difficult terrain and have helped in the economic development of these areas.

 

Roads can also be classified on the basis of the type of material used:
(a) Metalled Road.
(b) Unmetalled Road.
(a) Metalled Road: These roads can be made of Cement, Concrete or even bitumen of coal, therefore, these are all weather roads.
(b) Unmetalled Road: These roads go out of use in the rainy season.

Road Density:
• The length of road per 100 sq. Km of area is known as density of roads.
• Distribution of road is not uniform in the country.
• Density of all roads varies from only 10.04 km in Jammu & Kashmir to 532.27 km in Uttar Pradesh (2007-08) with national average of 125.02 km (2007-08).
• In the year 1996-97, the national average density of road was 75 km.
• Road transportation in India faces a number of problems.
• Keeping in view the volume of traffic and passengers, the road network is inadequate.
• About half of the roads are unmetalled and this limits their usage during the rainy season.
• The national highways are inadequate too.
• Moreover, the roadways are highly congested in cities and most of the bridges and culverts are old and narrow.
• In the recent years, fast development of road network has taken place in different parts of India.

 

RAILWAYS

• Railways are the most important mode of transportation for freight and passengers in India.
• Railways also make it possible to conduct different activities like business, sightseeing, pilgrimage, etc. along with transportation of goods over longer distances.
• Apart from an important means of transportation the Indian railways have been a great integrating force for more than 150 years.
• The first train ran between Mumbai to Thane in the year 1853 covering an area of 34 kms.
• Railways in India bind the economic life of the country as well as accelerate the development of the industry and agriculture.

Rail Network:
• The Indian railways have a network of 7,133 stations spread over a route length of 64,460 km.
• With a fleet of 9,213 locomotives,
• 53,220 passenger service vehicles,
• 6,493 other coach vehicles and 2,29,381 wagons as on March 2011.

 

DISTRIBUTION OF RAILWAYS

• The Indian railway is now reorganized into 16 zones.

Development of Railways:

1. The distribution pattern of the railway network in the country has been largely influenced by physiographic, economic and administrative factors.
2. The northern plains with their vast level land, high population density and rich agricultural resources provided the most favourable condition for their growth. However, a large number of rivers requiring construction of bridges across their wide beds posed some obstacles.
3. In the hilly terrains of the peninsular region, railway tracts are laid through low hills, gaps or tunnels.
4. The Himalayan mountainous regions too are unfavourable for the construction of railway lines due to high relief, sparse population and lack of economic opportunities.
5. Likewise, it was difficult to lay railway lines on the sandy plain of western Rajasthan, swamps of Gujarat, forested tracks of Madhya Pradesh, Chhattisgarh, Orissa and Jharkhand.
6. The contiguous stretch of Sahyadri could be crossed only through gaps or passes (Ghats).
7. In recent times, the development of the Konkan railway along the west coast has facilitated the movement of passengers and goods in this most important economic region of India. It has also faced a number of problems such as sinking of track in some stretches and landslides.
8. Today, the railways have become more important in our national economy than all other means of transport put together.
9. However, rail transport suffers from certain problems as well:
    (a) Many passengers travel without tickets.
    (b) Thefts and damaging of railway property has not yet stopped completely.
    (c) People stop the trains, pull the chain unnecessarily and this causes heavy damage to the railway.

 

PIPELINES

• Pipeline transport network is a new arrival on the transportation map of India.
• In the past, these pipelines 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.
• The far inland locations of refineries like Barauni, Mathura, Panipat and gas based fertilizer plants could be thought of only because of pipelines.
• Initial cost of laying pipelines is high but subsequent running costs are minimal.
• It rules out trans-shipment losses or delays.

MANUFACTURING: Production of goods in large quantities after processing from raw material to more valuable products is called "Manufacturing".

INDUSTRY: Industry refers to an economic activity that is concerned with the production of goods, extraction of minerals or the provision of services.

 

THE ECONOMIC STRENGTH OF A COUNTRY IS MEASURED BY THE DEVELOPMENT OF MANUFACTURING INDUSTRIES.

 

IMPORTANCE OF MANUFACTURING INDUSTRIES:
(a) Industrial growth helps in modernising the agricultural activities by providing machinery, chemicals, irrigation facilities, insecticides, pesticides, etc..
(b) Industrial growth helps in reducing the unemployment and poverty.
(c) Industrial growth can earn foreign exchange by exporting the finished goods and thus, can expand its trade and commerce.
(d) Any country with high level of manufacturing activities becomes prosperous.

 

CONTRIBUTION OF INDUSTRY TO NATIONAL ECONOMY:
(a) The share of manufacturing sector in the GDP (Gross Domestic Product) has been stagnant at 17% over the last two decades.
(b) The total contribution of industry to the GDP is 27% out of which 10% comes from mining, quarrying, electricity and gas.
(c) The growth of the manufacturing sector had been 7% in the last decade. Since 2003, the growth rate has been 9 to 10% per annum. The desired growth rate over the next decade is 12%.
(d) The National Manufacturing Competitiveness Council (NMCC) has been set with the objectives of improving productivity through proper policy interventions by the government and renewed efforts by the industry.

 

INDUSTRIAL LOCATION
Factors effecting the location of an Industry:
(a) Physical Factors
(b) Human Factors
(c) Key to decision of industrial location is "LEAST COST".
(d) Government policies and specialized labours also influence the location of industry.

Agglomeration Economies: Many Industries tend to come together to make use of the advantages offered by the urban centre's known as agglomeration economies. Gradually, a large industrial agglomeration takes place.

• Industrialization leads to Urbanization.

 

INDUSTRIAL SYSTEM

• An industrial system consists of inputs, processes and outputs.

Input: Raw materials, labour, costs of land, transport, power and other infrastructure.

Process: All activities that convert the raw material into finished products.

Output: End/ Final/Finished product and the income earned from it.

 

INDUSTRY – MARKET LINKAGE

 

CLASSIFICATION OF INDUSTRIES:

1. On the basis of Raw Materials:
These types of industries are classified depending on the type of raw materials they use.
(a) Agro Based Industries: Use plant and animal based products as their raw materials. E.g. Food processing, vegetable oil, cotton textile, dairy products, etc.
(b) Mineral Based Industries: Primary industries that use mineral ores as their raw materials. The products of these industries feed other industries. Iron made from iron ore is the product of mineral based industry. E.g. Iron& Steel, Cement, Machine Tools, etc.

According to their main role:
1. Basic or Key Industries: These industries supply their products or raw materials to manufacture other goods, e.g. iron and steel, copper smelting, aluminium smelting, etc.
2. Consumer Industries: These industries produce goods which are directly used by consumers, e.g. sugar, paper, electronics, soap, etc.

2. On the basis of Investment:
These types of industries are classified depending on the amount of capital invested, number of people employed and the volume of production.
(a) Large Scale Industries: In India, on an industry, if the capital invested is more than 1 crore, then it is called Large Scale Industry. e.g. Iron & Steel Industries, Automobile Industries, etc.
(b) Small Scale Industries: In India, on an industry, if the capital invested is less than 1 crore, then it is called Small Scale Industry. E.g. Silk weaving, Food processing industries, etc.

INDUSTRIAL POLLUTION AND ENVIRONMENTAL DEGRADATION
• Industries are responsible for majorly four types of pollution: Air, Water, Land and Noise.
• The polluting industries also include thermal power plants.

(a) Air Pollution: High proportion of carbon dioxide, sulphur dioxide and carbon monoxide create air pollution. Suspended particulate matters also create problems. Smoke is emitted from chimneys of various factories. Some industry also pose the risk of leak of hazardous chemicals; the way it happened during the Bhopal Gas Tragedy. Air pollution has adverse effect on human health, animals, plants, buildings, and the atmosphere as a whole.

(b) Water Pollution: Organic and inorganic industrial wastes and effluents cause water pollution. Paper, pulp, chemical, textile, dyeing, petroleum refineries, tanneries, etc. are the main culprits of water pollution.

(c) Thermal Pollution: It occurs when hot water from factories or thermal plants is drained into rivers and ponds before cooling. This plays havoc with the aquatic life.
Waste from nuclear power plants contains highly radioactive materials and it needs to be properly stored. Any leakage of radioactive material can cause short term and long term damages to humans as well as to other life forms.

(d) Noise Pollution: Noise pollution can result in constant irritation, hypertension and hearing impairment. Factory equipments, generators, electric drills, etc. are the major sources of noise pollution.

 

Preventing Environmental Degradation by Industry:
(a) Industries are responsible for majorly four types of pollution: Air, Water, Land and Noise.
(b) Water should be reused and recycled in the industry.
(c) This will help in minimizing the use of freshwater.
(d) Rainwater harvesting should be promoted.
(e) Hot water and effluents should be treated before being released in rivers and ponds.

(b) Amarkantak Plateau, Maikal hills and the plateau region of Bilaspur-Katni are the main areas of bauxite deposits.
(c) In 2009-10 Orissa was the largest producer of bauxite in India with 34.97%.
(d) Panchpatmali in Koraput district is the most important centre of bauxite deposit in Orissa.
(e) Aluminum is incredibly popular because it is Lightweight, Strong, Durable, Ductile, Malleable, etc.
(f) Aluminum is used in: Automobiles, Aircraft, Spacecraft, Packaging (Cans, Foil, frame, etc). Food and beverage containers, etc.

Q5. Write a note on Geo Thermal Energy.
Ans: Geo thermal energy refers to the heat and electricity produced by using the heat from the interior of the Earth. Geothermal energy exists because; the Earth grows more and more hot with increasing depth. Where the geothermal gradient is high, high temperatures are found at shallow depths. Groundwater in such areas absorbs heat from the rocks and becomes hot. It is so hot that when it rises to the earth's surface, it turns into steam. This steam is used to drive turbines and generate electricity.
There are several hundred hot springs in India, which could be used to generate electricity. Two experimental projects have been set up in India to harness geothermal energy. One is located in the Parvati valley near Manikarn in Himachal Pradesh and the other is located in the Puga Valley, Ladakh.

Q6. Differentiate between Hydro Electricity and Thermal Electricity.
Ans:

Q7. Minerals are essential part of our life, it is important to know about the occurrence of minerals. Mention different modes where minerals occur?
Ans: Minerals are usually found in ores. Minerals generally occur in the following forms:
(a) In Igneous and Metamorphic Rocks: The smaller occurrences are called veins and the larger occurrences are called lodes. They are usually formed when minerals in liquid/molten and gaseous forms are forced upwards through cavities towards the earth's surface. Examples: tin, copper, zinc, lead, etc.

(b) In Sedimentary Rocks: In these rocks, minerals occur in beds or layers. Coal, iron ore, gypsum, potash salt and sodium salt are the minerals found in sedimentary rocks.

(c) By Decomposition of Surface Rocks: Decomposition of surface rocks and removal of soluble constituents leaves a residual mass of weathered material which contains ores. Bauxite is formed in this way.

(d) As Alluvial Deposits: These minerals are found in sands of valley floors and the base of hills. These deposits are called placer deposits. They generally contain those minerals which are not corroded by water. Examples; gold, silver, tin, platinum, etc.

(e) In Ocean Water: Most of the minerals in ocean water are too widely diffused to be of economic importance. But common salt, magnesium and bromine are mainly derived from ocean waters.

Q8. Describe the distribution of iron ore in India.
Ans: Iron ore is the basic mineral and the backbone of industrial development. The major iron ore belts in India are:
(a) Orissa Jharkhand Belt: Badampahar mines in the Mayurbhanj and Kendujhar districts of Orissa have high grade hematite ore. Additionally, hematite iron ore is mined in Gua and Noamundi in Singhbhum district of Jharkhand.

(b) Durg Bastar Chandrapur Belt: This belt lies in Chhattisgarh and Maharashtra. The Bailadila range of hills in the Bastar district of Chhattisgarh have very high grade hematite ore. This hilly range has 14 deposits of super high grade hematite ore. Iron from these mines is exported to Japan and South Korea via Vishakapatnam port.

(c) Bellary Chitradurga Chikmaglur Tumkur Belt: This belt lies in Karnataka. The Kudremukh mines located in the Western Ghats are a 100 percent export unit. The ore from these mines is transported as slurry through a pipeline to a port near Mangalore.

(d) Maharashtra Goa Belt: This belt includes the state of Goa and Ratnagiri district of Maharashtra. The ores in these mines are not of very high quality. They are exported through Marmagao port.
