Agriculture in India

Long Answer Type Questions

1. Briefly discuss the important characteristics of Indian agriculture.

Ans. The important characteristics of Indian agriculture are discussed below-

Subsistence farming: India being a highly populated country, most of the food grains grown here are mainly consumed by the farmers and their families. Not much agricultural produce is left for the purpose of export and sale.
Importance of food crops: In India, priority is given to cultivation of food crops rather than cash crops to meet the needs of the growing population. More than 75% of cultivated land in India is used for growing food crops. About 52% of the total income from agricultural products comes only from food crops.
Use of animals: Indian agriculture is not yet developed to an extent that use of modern machineries such as tractors and harvesters would be popular everywhere. Till date, in many regions farmers are dependent on animals like bullocks and buffaloes for ploughing agricultural plots.
Dependence on monsoon winds: Agricultural activities in most places of India are carried out once a year depending on the arrival of monsoons. However, advent of monsoon winds may also lead to certain natural calamities such as floods, drought and excessive heavy rainfall which adversely affect agricultural activities.
Irrigation: Most agricultural plots in India have been brought under the scope of irrigation. In these plots, two to three crops are grown per year.
Small land holdings: Most agricultural plots in India are small and fragmented mainly due to different laws of succession. Such small land holdings are not suitable for using modern agricultural equipments. Hence, crop yield per hectare remains low.
Uncontrolled use of chemical fertilisers and insecticides: Indiscriminate use of chemical fertilisers and pesticides to increase crop production has led to soil and water pollution.
Lack of fodder crops: Although Indian agriculture mainly focuses on the cultivation of food crops, no importance as such has been given to the cultivation of fodder crops.
Variety of crops: Different types of crops are extensively cultivated in India such as food crops (rice, wheat, millets, corn), oilseeds (mustard, sunflower, groundnut), cash crops (tea, coffee, jute, rubber), pulses, spices etc.

2. Mention the problems of Indian agriculture along with its remedial measures.

Ans. There are numerous problems pertaining to agriculture in India. Those problem along with their probable remedial measures are discussed below-

Low yield per hectare: Yield of crops per hectare is quite low in India. This is due to lack of-use of HYV seeds; good quality chemical fertilisers, pesticides and insecticides; proper irrigation facilities and modern machineries.
Solution: Post independence, many policies have been adopted in the Five-Year Plans in order to improve the agriculture sector in India. This has increased crop yield per hectare to some extent.
Low per capita land ownership: Per capita land ownership in India is only 0.3 hectare which is quite less than other developed countries (where it is 11 hectare per capita). Also, fragmented and small land holdings are not suitable for using modern farming equipments and techniques.
Solution: Small land holdings should be consolidated so that co-operative farming. can be practiced to increase crop yield.
Soil erosion: Unscientific agricultural methods, uncontrolled grazing by animals and indiscriminately cutting down trees have led to soil erosion and loss of soil fertility.
Solution: Terrace cultivation, contour ploughing, use of scientific methods of farming are being encouraged to minimise soil erosion. Also, organic fertilisers and vermicompost are used to maintain soil fertility. Crop rotation is also practiced to maintain the fertility of soil. The Indian Institute of Soil and Water Conservation is also taking an active part in preventing soil erosion and conserving soil fertility.
Lack of knowledge about agriculture and poverty: Farmers do not have adequate knowledge about modern methods of farming and agricultural equipments. Uncontrolled use of chemical fertilisers and pesticides without assessing the extent of requirement or the nature of soil lead to both soil and water pollution. Apart from these, poor economic condition of farmers prevent them from investing in agriculture. All these have led to low crop production.
Solution: Proper education regarding agricultural techniques and machineries should be imparted to the farmers. Simultaneously, co-operative farming methods need to be popularised and agricultural loans must be sanctioned as per need to the farmers.
Faulty land distribution system in India: Faulty land distribution by the government has created many marginal or landless farmers in India.
Solution: Laws have been passed to rectify the land distribution system so that the economic conditions of marginal and landless farmers can improve.
Investment based on moneylenders: Most farmers in India are poor and so they often have to take loans from moneylenders. In order to repay the loans, the farmers are forced to sell off their crops at very low prices.
Solution: The government has instructed several nationalised banks and rural banks to sanction agricultural loans at low interests for poor farmers. Also, necessary arrangements have been made so that farmers can sell their produce directly at reasonable prices. In these ways, the farmers can achieve a good profit.

3. Discuss the suitable geographical conditions required for cultivating rice.

Or, Discuss the suitable geographical conditions for growing rice in the northern plains or the Gangetic plains of India.

Ans. The suitable geographical conditions required for cultivating rice are discussed below-

1. Physical conditions

Climate: Rice grows best in hot and humid tropical monsoon climate. An average temperature of 20-30°C and annual rainfall of 100-200 cm favour rice cultivation. During the growing phase, approximately 12.5 cm more of monthly rainfall is desirable. Dry sunny weather is best during maturation and harvesting of the crop.
Soil: Fertile loamy soil and alluvial soil found in river valleys are best suited for rice cultivation. Presence of a layer of non- porous clayey soil beneath the alluvial soil helps in water retention, which in turn, is favourable for rice cultivation.
Topography: Rice grows best on land flooded with water. Hence, flat river valleys and deltaic plains are preferred for growing rice.
Elevation of land: Generally rice grows on lands which are at sea level or only a few metres above sea level. However, there are certain exceptions to this fact. In Kerala, rice grows below sea level in Alappuzha district. In Dehradun, rice grows at an altitude of 435 m, in Mussourie at an altitude of 2006 m while in Kashmir valley region, it grows at an altitude of 1850 m.

2. Economic conditions

Labour: Cheap and skilled labour is required for ploughing land, weeding, sowing saplings, threshing grains and other activities.
Others: High yielding variety seeds, chemical and organic fertilisers, irrigation facilities and modern farming equipments are required for rice cultivation. All these things require huge capital investment. Also, market demand plays an important role in rice production.

4. Discuss the reasons for prosperity of agriculture in Punjab and Haryana.

Ans. Punjab and Haryana are two states in India which have flourished due to agriculture. The reasons for agricultural prosperity of these two states are discussed below-

Soil: The region comprises of rich alluvial soil deposited by the Indus river and its five famous tributaries. Although in some places the soil is a little sandy, but the mineral content of the soil makes it very fertile and highly suitable for agriculture.
Irrigation: The largest multi-purpose river valley project, i.e. the Bhakra-Nangal project provides irrigation water to all the agricultural fields of both the states. Due to such ready availability of water, three to four crops are grown every year.
HYV seeds: High Yielding Variety seeds were first used in this region in India during the Green Revolution. Use of such seeds in case of rice, wheat, cotton and other crops have increased crop yield to a large extent.
Use of machineries: In Punjab and Haryana, there are many large agricultural tracts. So, different modern agricultural machineries like tractors, harvesters, etc. can be easily used. This helps in higher crop production.
Use of chemical fertilisers and insecticides: In India, the maximum amount of chemical fertilisers and insecticides are used in the states of Punjab and Haryana. This results in high crop yield.
Agricultural education: Education regarding different aspects of agriculture such as modern farming techniques, types of fertilisers to be used depending on nature of soils, irrigation techniques etc., are imparted to farmers by several governmental and non-governmental organisations. Research works are conducted on regular basis in different universities for further betterment of agriculture.
Others: Facilities like power supply, market, transport, godowns etc. has helped in improving agriculture in Punjab and Haryana. Also, the government has taken initiative to fix the price of the crops so that the farmers gain profits.

5. Discuss suitable geographical conditions for cultivation of tea.

OR, Discuss the physical factors favourable for growth of tea plantation in India.

Ans. Tea is the main beverage crop of India. India occupies the second position in global tea production. The suitable geographical conditions required for tea cultivation are discussed below-

1. Physical conditions

Climate: Tea grows best in warm and wet, tropical monsoon climate. [i] Temperature: An average temperature ranging from 16-30°C is suitable for tea cultivation. Although tea can tolerate moderately high and low temperatures, hailstorms in summer and snowfall in winter are harmful for tea. [ii] Rainfall: An average annual rainfall of 150-250 cm is favourable for tea cultivation. [iii] Others: Sultry weather with low rainfall, dense fog, frost and scorching sunlight adversely affect growth of tea.
Soil: Fertile loamy soil rich in iron is suitable for tea plants. Chernozem soil found in the grassland of hill slopes is also favourable for the cultivation of tea as it is rich in humus.
Sloping land: Tea plants cannot tolerate water stagnation near their roots. So hill slopes and rolling plateaus are preferred for cultivating tea.
Elevation: High mountain slopes where the climate is cool and have no chances of snowfall are highly preferable for tea cultivation. In India, tea gardens are seen at an altitude varying from 90m in the Terai region to about 1980 m in Darjeeling.

2. Economic conditions

Labour: Tea being a labour-intensive crop require huge number of skilled labourers. Especially women labourers are employed for plucking tea leaves as they are quick and nimble. They also look after the tea plants and tend to the tea gardens.
Others: Tea is a plantation crop. Modern machineries, fertilisers, insecticides as well as adequate capital investment, good transport network, national and international demand, are some factors on which tea cultivation depends.

6. Discuss the suitable geographical conditions required for cultivation of coffee.

Ans. Coffee is the second most important beverage crop of India right after tea. The suitable geographical conditions required for the cultivation of coffee are discussed below-

1. Physical conditions

Climate: Coffee grows best in hot and humid tropical climate. Especially equatorial climate is favourable for coffee cultivation. [i] Temperature: An average temperature ranging from 20-25°C is ideal for coffee. [ii] Rainfall: An annual average rainfall of 150-250 cm is required for growing coffee. [iii] Shade trees: Coffee plants are sensitive to direct sunlight. So trees with broad canopy are planted in between coffee plants so that they can provide shade.
Soil: Fertile laterite soil of volcanic origin and red loamy soil are best suited for coffee cultivation.
Type of land: Sloping highlands, especially foothills of mountains are ideal for coffee cultivation. Large quantities of coffee are grown in the southern region of Karnataka, mountainous region of Andhra Pradesh, hilly regions of north Kerala and northern part of Tamil Nadu.

2. Economic conditions

Labour: Coffee being a plantation crop require abundant cheap labour for transplanting, plucking coffee berries, drying the coffee beans etc.
Others: Coffee is a plantation crop. The plantations need to have proper infrastructure so that all processes involved in preparing coffee can be carried out in the plantation itself. This includes transplantation of seedlings to processing the beans and finally packing the coffee powder. For this, adequate capital investment is necessary. Apart from these, transportation of coffee from the coffee plantations to nearby ports (for exporting) require a well-built transport network.

7. Discuss the suitable geographical conditions required for cultivation of cotton.

Ans. Cotton is the most important fibre crop of India. The geographical conditions required for growing cotton are discussed below-

1. Physical conditions

Climate: Cotton is a crop native to the tropical and sub-tropical regions. [i] Temperature: An average temperature of 20-26°C is ideal for cultivating cotton. [ii] Rainfall: An average annual rainfall of 60-100 cm is required for growing cotton. However, in north-west and south India, cotton is also cultivated in areas receiving less than 60cm rainfall with the help of irrigation. [iii] Sea winds: Saline winds from the seas are good for cotton cultivation.
Soil: Fertile loamy soil rich in lime is good for cotton. Chernozem soil and black soil (regur) of volcanic origin found in the Deccan Plateau region are favourable for cotton cultivation.
Type of land: Plain lands or gently rolling plains with proper drainage pattern are suitable for growing cotton as cotton cannot withstand water logging.

2. Economic conditions

Labour: Abundant skilled labourers are required for sowing the seeds, picking the cotton bolls, pressing the cotton into bales which are then sent to factories for making threads.
Fertilisers: Cotton being a soil-exhausting crop require suitable quantities of chemical and organic fertilizers.
Insecticides: Cotton plants are susceptible to pests like boll weevil, pink bollworm and spotted bollworm. Thus, large quantities of insecticides are required during cultivation of cotton crop.
Others: HYV seeds, proper irrigation facilities, modern agricultural equipments and huge capital are some factors on which cotton cultivation depends. Apart from these, market demand for cotton and well-connected transport system also influence cotton production.

8. Discuss the suitable geographical conditions required for cultivation of sugarcane. Write a short note on the trade of sugarcane in India.

Ans. Sugarcane is a very important cash crop of India, as it is the main source for producing sugar. The suitable geographical conditions required for cultivation of sugarcane are discussed below-

1. Physical conditions

Climate: Sugarcane is a kharif crop and is grown in tropical regions. [i] Temperature: An average temperature of 20-27°C is suitable for growing sugarcane. Higher temperature may damage the crop. [ii] Rainfall: An average annual rainfall of 75-150 cm is required for cultivation of sugarcane. However, it can also be grown in areas receiving low rainfall with the help of irrigation. [iii] Coastal climate: This type of climate with saline environment influence the sweetness of the sugarcane juice as well as the overall growth of the plants. So sugarcane is widely cultivated in the western region of India. [iv] Fog: Sugarcane is highly susceptible to fog, smog and frost.
Soil: Fertile loamy soil rich in lime and black soil are best for growing sugarcane.
Type of land: Gently rolling plains with proper drainage facility are most suitable for growing sugarcane as there is less possibility of water stagnation.

2. Economic conditions

Labour: Abundant cheap and skilled labourers are required for sowing the seeds and harvesting the crop. So, sugarcane is usually cultivated in densely populated regions.
Transport: A well-connected transport system is extremely essential for sugarcane cultivation as the juice needs to be extracted within 24 hours of cutting the plants and transported to the sugar factories. If it is not done, both the quantity and sugar content of the juice get affected. For this reason, most sugar factories are established in the vicinity of the sugarcane plantations.
Capital: Sugarcane is a soil-exhausting crop. Hence, a substantial amount of fertilisers is required. Also, insecticides, irrigation facilities, labour supplies needed for cultivating the crop require a huge amount of capital.
Market demand: Sugarcane is a crop which cannot be stored in godowns or cold storages. It has to be processed instantly. Hence, market demand of sugar is a great controlling factor of sugarcane cultivation. In recent times, sugarcane cultivation is expanding keeping in mind the huge population of India.

Short Explanatory Answer Type Questions

1. Classify the crops of India according to their sowing season.

Ans. According to their sowing season, crops of India can be classified into three categories which have been tabulated below-

Crop	Sowing Season	Examples
Kharif crops	Crops are sown just before the arrival of the monsoons, i.e., in the month of June and harvested after the autumn season, i.e., in the month of November.	Aman rice, jute, cotton, sugarcane, jowar, bajra, ragi, maize.
Rabi crops	Crops are sown just before the arrival of the winter season, i.e., in the month of December and harvested before the arrival of the summer season, i.e., in the month of March.	Wheat, barley, oat, mustard, lentils.
Zaid crops	Crops are sown before the arrival of the summer season, i.e., in the month of March and harvested before the arrival of the monsoons, i.e., in the month of June.	Watermelon, tomato, brinjal, cucumber, muskmelon.

2. How can you classify rice?

Ans. Rice can be classified into three categories according to the season in which it is grown. These are—

Type of rice	Growing season
Aaus	This variety of rice is sown during the summer season (April-May) and harvested during the monsoons (August-September). The meaning of the word ‘aus’ is early. This crop matures rapidly.
Aman	This variety of rice is sown during the monsoons (June) and harvested during the winter season (December-January). This crop is also known as ‘Aghrani rice’ in West Bengal.
Boro	This variety of rice is sown during the winter season (November-December) and harvested during the summer season (April-May).

3. Classify the crops of India according to their nature of uses.

Ans. Crops grown in India can be broadly classified into two types according to their nature of uses-1. Food crops and 2. Cash crops.

Food crops can be further classified into three categories- (1) Grain crops: Rice, wheat. (2) Beverage crops: Tea, coffee. (3) Other food crops: Sugarcane, spices, lentils, fruits.
Cash crops can be also further classified into three categories- (1) Oilseeds: Mustard, sesame, groundnut. (2) Fibre crops: Cotton, jute. (3) Other crops: Rubber,

4. How can you classify wheat?

Ans. Wheat can be classified into two types according to the season in which it is grown. These are-

Type of wheat	Growing season
Winter wheat	This type of wheat is sown in the autumn season and harvested before the onset of the summer season.
Spring wheat	This type of wheat is sown during the spring season and harvested at the end of the summer season.

In India, mostly winter wheat is cultivated. However, spring wheat is also cultivated in some scattered regions of Uttarakhand and Himachal Pradesh.

5. Why does wheat dominate in the agriculture of north India?

Ans. The reasons behind the predominance of wheat in the agriculture of north India are discussed below-

Temperature in the Punjab plains as well as in the upper and middle Gangetic plains remain around 14°-20°C during winter, which is ideal for wheat cultivation.
Rainfall caused by western disturbances in the wheat producing regions of north India during winter season is highly favourable for wheat cultivation. Also, improved irrigation facilities provide the necessary water required for growing wheat.
The fertile heavy loamy soils and clayey alluvial soils of north India are highly suitable for wheat cultivation.
The gently rolling plains of north India favour wheat cultivation.
Majority of the population in Punjab, Haryana and Uttar Pradesh is engaged in agriculture. This huge workforce positively helps in wheat cultivation.

6. Name the important plantation crops of India and mention the regions where they are cultivated.

Ans. Important plantation crops of India: The two most important plantation crops grown in India are-tea and coffee.

Regions of tea and coffee cultivation:

Tea: Approximately 80% of the total tea production in India comes from the states of Assam and West Bengal. The southern states of India namely Tamil Nadu, Kerala and Karnataka account for the remaining 20%. The sloping plains of the Brahmaputra Valley and the Terai region in Assam which includes the districts of Darrang, Sivasagar, Lakhimpur and Cachar are well known for tea cultivation. Apart from this, tea is also grown in the mountainous and Terai region of West Bengal which includes the districts of Darjeeling, Kalimpong, Jalpaiguri, Cooch Behar and North Dinajpur.
Coffee: Karnataka (70%) , Kerala (21%) and Tamil Nadu (6%) are the leading coffee producing states of India.
Chikmagalur, Kodagu, Hassan, Shimoga and Mysore districts of Karnataka; Palakkad, Wayanad, Idukki and Kollam districts of and Kerala; Madurai, Salem and Coimbatore districts of Tamil Nadu are well known for coffee cultivation.

7. Why is coffee cultivation predominant in south India?

OR, Mention any two reasons for the growth of coffee cultivation in south India.

Ans. The hilly regions of Karnataka, Andhra Pradesh, Tamil Nadu and Kerala are famous for coffee cultivation in India. The reasons behind the predominance of coffee cultivation in these states of south India are as follows-1. The weather in this region is favourable for coffee cultivation since the average temperature ranges between 20-30°C and the annual rainfall is approximately 150-250 cm. 2. Fertile laterite soil of volcanic origin is found here which is highly suitable for coffee cultivation. 3. The hill slopes of this region (elevation ranging from 800-1600 m) are ideal for the growth of coffee as they help in avoiding water stagnation. 4. Since cultivation of tea as a beverage crop has not gained popularity in south India, coffee as an alternative beverage crop has taken its place.

8. What do you mean by Green Revolution?

Ans. In post-Independent India, during the late ’60s, several measures were adopted to increase agricultural produce by implementing modern methods. Using high yielding variety (HYV) seeds, applying chemical fertilisers and insecticides, using modern farming equipments (such as tractors and harvesters) and implementing irrigation facilities and improved agricultural techniques were some of the highlights of this revolution. This led to a sharp increase in crop production. From 1968 to 1978, there was a rapid increase in wheat production mostly in the states of Punjab and Haryana which was famously called the ‘Green Revolution’. In 1960-61, total wheat production in India was 1 crore 10 lakh ton which tripled to an amount of 3 crore 63 lakh ton in 1980-81.

9. Why is wheat cultivated in north-west India in spite of being a crop of the temperate region?

OR, Why wheat is cultivated during winter in India?

Ans. Wheat is the second most important food crop of India. In spite of being a crop of the temperate region, wheat is grown in large areas in north-west India during winter because of the following reasons-

Climate: As north-west India lie in the sub-tropical and temperate zones, the climate prevalent here is ideal for wheat cultivation during the winters.
Temperature: An average temperature ranging between 14-20°C is favourable for wheat cultivation. Such temperature condition is found in north-west India during winter.
Availability of water: Generally, an average annual rainfall of 50-100 cm is best suited for wheat cultivation. The north- western parts of India receive rainfall during winter caused by western disturbances. However, this rainfall is not sufficient enough for growing wheat. So, the need of extra water is fulfilled by improved irrigation facilities.
Sunny and cool weather: In case of wheat cultivation, moist moist and cool climatic conditions are necessary while sowing the seeds, dry and warm climate when the panicle comes out, light rainfall when the grains mature and sunny and cool climate while harvesting. Such kind of climatic conditions prevail in north-west India.
Frost-free days: Wheat cultivation requires 110 frost-free days. Although the states of north-west India experience extreme cold weather in winter, there is no occurrence of snowfall in most of these regions. This provides a condition suitable enough for wheat cultivation.

Apart from the above-mentioned reasons, extensive plainlands and fertile alluvial soil of north-west India are highly favourable for wheat cultivation.

10. Mention three important characteristics of Indian agriculture.

Ans. Three important characteristics of Indian agriculture are as follows-

Subsistence farming: India being a highly populated country, most of the food grains grown are mainly consumed by the farmers and their families. Not much agricultural produce is left for the purpose of export and sale.
Importance of food crops: In India, priority is given to cultivation of food crops rather than cash crops to meet the needs of the growing population. More than 75% of cultivated land in India is used for growing food crops. About 52% of the total income from agricultural products comes only from food crops.
Use of animals: Indian agriculture is not yet developed to an extent that the use of modern machineries such as tractors and harvesters would be popular everywhere. Till date, in many regions farmers are dependent on animals like bullocks and buffaloes for ploughing agricultural plots.

11. Discuss any three problems of Indian agriculture.

Ans. Three problems of Indian agriculture are discussed below-

Low yield per hectare: In India, yield per hectare of crops is quite low. In the year 2016-17, yield of rice was only about 2550 kg per hectare. The causes behind such low yield of crops per hectare are- (1) limited irrigation facilities, (2) less use of fertilisers, insecticides and pesticides, (3) limited use of modern machineries and (4) poor knowledge of farmers regarding modern and improved agricultural practices.
Ownership of agricultural lands: Most Indian farmers are either marginal farmers or landless farmers. This is because large tracts of land are owned by few rich farmers. The landless peasants lose interest in cultivating crops as they earn no substantial benefit from it.
Dependence on monsoon: Agriculture in India is heavily dependent on the monsoons. Irregularity in the onset and retreat of monsoon along with occurrence of floods and drought adversely affect crop production in the country.

12. What are the reasons behind the low yield of crops per hectare in India?

Ans. The different reasons behind the low yield of crops per hectare in India are as follows-

Small land holdings: Most of the agricultural plots in India are quite small in size. This restricts the use of modern machineries and implementation of improved farming techniques. As a result, crop yield per hectare becomes low.
Limited use of HYV seeds: In India, high yielding variety seeds of different crops are still not used extensively. Thus, yield of crops per hectare remains low.
Less use of fertilisers and insecticides: Fertilisers and insecticides are less used while cultivating crops in India. This leads to low crop yield per hectare.
Lack of irrigation facilities: Not all agricultural plots in India are benefited by irrigation facilities. So, in that case, cultivation of crops becomes dependent on rainfall only. This too, causes low yield of crops per hectare.
Subsistence farming: Most farmers in India produce crops that are sufficient for their own consumption only. There is insufficient surplus left for sale or export. This leads to low yield of crops per hectare.

13. Why is Assam Assam famous for tea cultivation?

Ans. The reasons for which Assam is famous for tea cultivation are as follows-

Favourable climate: Tea is a tropical plant. An average temperature of 20-30°C and annual rainfall of 200 cm are favourable for tea cultivation. Such weather conditions prevail in this state. Almost in every month, rainfall occurs to some extent here.
Sloping land: The undulating and sloping landscape of this state is ideal for tea cultivation.
Soil: Tea thrives well in the slightly acidic friable loamy soil found here.
Other reasons: Investors have invested large sums of money in tea estates of Assam. Apart from this, Guwahati Tea Auction Centre, proximity to the Kolkata port and modern infrastructure have facilitated tea cultivation in Assam.

14. Mention the solutions for the problems of Indian agriculture.

Ans. The solutions for the problems of Indian agriculture are as follows-

Use of HYV seeds: The Indian Council of Agricultural Research (ICAR) has taken initiative to popularise the use of high yielding variety seeds among farmers to increase crop yield. The National Seeds Corporation Limited (NSCL), State Farms Corporation of India Limited (SFCI) and numerous other non-governmental organisations are working to increase the use of HYV seeds all over India. About 500 HYV seeds of rice and 250 HYV seeds of wheat are being currently used in Indian agriculture.
Use of chemical fertilisers: Use of chemical fertilisers such nitrogenous fertilisers, phosphate-based fertilisers and potash has been encouraged to increase crop yield. Many government organisations have set up units which manufacture different chemical fertilisers. However, the produce is not sufficient enough to meet the demand of fertilisers in India. Hence, huge amounts of fertilisers are imported. Application of fertilisers have led to an increase in crop yield in recent times.
Soil conservation: Several steps have been adopted for conservation of soil in India which includes terrace cultivation, contour farming and different modern methods of farming. The Indian Institute of Soil and Water Conservation (IISWC) has been established to look after matters pertaining to soil conservation. Apart from these, the state governments too have taken initiatives to bring about soil conservation.

15. What is the importance of agriculture in India?

Ans. The importance of agriculture in India is discussed below-

Employment: Agriculture is one of the most important means of employment in India. A majority of the population is either directly or indirectly dependent on agriculture.
Source of food: Agriculture caters to the food requirement of the Indian population.
Source of National Income: In India, agriculture is one of the main source of National Income.
Source of raw materials: Different raw materials required for agro-based industries such as, tea, coffee, cotton textile, jute textile, sugar, edible oil and food processing are provided by agriculture.
Source of foreign currency: Agricultural products like jute, tea, coffee, sugar, cashew nuts, tobacco and spices are exported to foreign countries. Thus, agriculture is a chief source of foreign currency.
Expansion of transport and business: Agriculture has helped in the expansion of trade and commerce as well as transport and communication in India. Agricultural products are transported to markets and agro-based raw materials are transported to industries across the country through roadways and railways.
Market: Different markets and trading centres have come up in different regions of India for the purpose of trading agricultural products. Thus, agriculture in India has a great economic importance.

Short Answer Type Questions

1. What do you mean by the term ‘agriculture’?

Ans. Agriculture was the very first step towards a settled human civilisation and has been a primary economic activity of man. The word ‘agriculture’ originates from two Latin words-‘ager meaning field or land and ‘culture’ meaning growing or cultivation. So, agriculture literally means cultivation of land. However, in recent times, agriculture is not only limited to growing crops but it also includes animal rearing, pisciculture, planting trees and other related activities. These are done with a motive to sustain and enhance human life.

8. Write short note on plantation agriculture.

Ans. The concept of plantation agriculture was introduced in the tropical and sub-tropical areas of Asia, Africa and America by the different colonial powers of Europe. In India, plantation agriculture was introduced by the British during the 19th century. Various cash crops such as rubber, tea and coffee are grown on plantation farms across many states of India like Karnataka, Tamil Nadu, Kerala, West Bengal and Assam. The main objective of plantation agriculture is to grow crops meant for sale using modern machinery, fertilisers and specialised labour. This results in greater yield of crops. Monoculture is seen in this form of agriculture.

9. Name some HYV seeds of cotton.

Ans. Some HYV seeds of cotton commonly used are-Sujata, Bharati, MCU-4, MCU-5.

10. What do you mean by cash crops?

Ans. The crops which are cultivated by farmers for sale and to earn profit are called cash crops. For example, sugarcane, cotton and jute are cultivated as cash crops in India.

11. What is crop rotation?

Ans. Crop rotation is the practice of successive cultivation of different crops in a particular sequence over a definite period of time on the same agricultural tract. For example, if wheat is grown in the first year on a piece of land, then in the next successive years potato, barley and pulses are grown on that piece of land. In the fifth year, wheat is again grown there. In this way, crop rotation is successively carried out.

12. What are the objectives of crop rotation?

Ans. The different objectives of crop rotation are-1. Maintaining soil fertility, 2. Protecting crops against pests, 3. Surplus crop production and 4. Preserving crop diversity.

13. How can you classify cotton?

Ans. According to the length of the fibre, cotton can be classified into four categories- 1. Very long staple cotton (equal to or more than 35 mm), 2. Long staple cotton (30-35 mm), 3. Medium staple cotton (25-30mm), 4. Short staple cotton (less than 25 mm). In India, the production of medium staple cotton is more.

30. What do you mean by subsistence agriculture?

Ans. The farming practice in which crops are grown with the sole purpose that the agricultural produce will be consumed by the farmers and their family members only is called subsistence agriculture. This type of agriculture is seen in some parts of Africa and south-east Asia.

31. State the importance of terrace cultivation.

Ans. The steep slope of land in hilly regions increases the speed of soil erosion. In terrace cultivation, the slope is cut into steps or stairs (resembling a terrace). Thus, the general slope of the land is reduced and flat stretches of land are created along the hills. This helps to reduce the speed of running water, thus reducing soil erosion. Terrace cultivation is commonly practiced for the cultivation of rice, wheat, soybean etc. Hence, terrace cultivation is of immense importance in reducing soil erosion and helping in soil conservation in the mountainous areas.

TOPIC – 2

Industries in India

Long Answer Type Questions

1. Discuss the factors which influence the location of industries.

OR, Which factors should be considered before choosing a location for setting up an industry?

Ans. Industries cannot be established anywhere and everywhere on the earth. The factors which must be considered before setting up an industry are discussed below-

Raw materials: Location of an industry primarily depends upon the type of raw materials that are being used in that particular industry. Raw materials are of two types-
1. Pure raw materials: The raw materials which do not lose weight during their processing into finished products are called pure raw materials. Example-Cotton, jute. One tonne of cotton or jute will produce one tonne of cotton fabric or jute goods. Thus, industries dependent on pure raw materials can be established anywhere in between the source of raw materials and the market as the transportation cost remains same.
2. Impure raw materials: The raw materials which lose weight during their processing into finished products are called impure raw materials. Example- Sugar manufactured from sugarcane have less weight than that of the raw material. So to reduce transportation cost, industries dependent on impure raw materials are established in the vicinity of the source of the raw material.
Water: Availability of water is essential for all industries for the industrial processes as well as for the workers. So industries are usually set up near waterbodies like rivers and lakes. Example-The iron and steel plant at Durgapur has been established near the Damodar river in West Bengal.
Power: Power is extremely important for the proper functioning of an industry especially thermal and hydroelectric power resources. For this reason, many industries in Europe and America have grown up centring the coalfields. In India also, there are many industries which have been built close to thermal and hydel power plants.
Transport: A well-connected transport system is required for sourcing the raw materials, taking the finished products to the nearby market or port (for importing and exporting purpose) and movement of ·labourers and other people associated with the industry. It is best to set up an industry at a location where cost of transportation is minimum..
Availability of labour: Establishment of an industry requires abundant supply of skilled and cheap labour. Availability of labour is such an important factor that Bangladesh has progressed in the cotton textile industry only due to the presence of abundant labour although adequate amount of cotton is not grown in this country.
Market: An industry develops depending on the market demand of a certain product. Wherever there is a demand for a particular product, industries based on that product are generally set up. Example-Although cotton is not cultivated in West Bengal, the cotton textile industry has flourished in the Hooghly region because of the large population that led to high demand for cotton clothes.
Capital: Huge capital investments are essential for setting up an industry. Adequate amount of capital is required to buy the plot, to set up the industry, to buy equipments and raw materials, to establish factory shade, to pay the wages of labourers and to provide continuous power supply. Example-Cotton textile industry has flourished to a great extent in western India due to huge capital investment by Gujarati and Parsi businessmen.

2. Explain in brief the factors responsible for development of cotton textile industry in Western India.

OR, Discuss the causes of concentration of cotton textile industries in the Mumbai-Ahmedabad region.

OR, Justify the concentration of cotton textile industry in the black soil region of Western India.

Ans. At present, there are many cotton textile mills concentrated in the western region of India (in the black soil region of western India) mainly in Maharashtra including the districts of Mumbai, Pune, Nagpur, Sholapur, Akola and Jalgaon and Gujarat including the districts of Ahmedabad, Surat, Bharuch, Vadodara and Rajkot. The causes behind the concentration of cotton textile industries in Western India are discussed below-

Best cotton-producing region: The black soil region of Maharashtra and Gujarat is extremely suitable for cotton cultivation. Hence, the raw materials (i.e., cotton) for cotton textile industry is readily available in this region.
Humid climate: Hot and humid climate of this region due to proximity to the Arabian Sea is favourable for cutting the yarn.
Power resources: Hydroelectric power plants in Ukai, Kadana (Gujarat) and Bhivpuri, Khopoli, Koyna (Maharashtra); thermal power plants in Trombay and Nasik (Maharashtra) provide the necessary power to the cotton textile mills.
Nearness to ports: Three important ports of India-Mumbai, Kandla and Nhava Sheva (Jawaharlal Nehru port) and other smaller ports namely Surat and Porbander are located in this region. These ports help in the export of cotton fabric and import of raw materials and necessary equipments.
Well-connected transportation system: The Western, Central and Konkan railways as well as the National Highways 3, 4, 6, 7 and 8 pass over this region thereby forming a well-connected transportation system. This transport network helps in acquiring raw materials and sending the finished products to different parts of the country.
Capital: Wealthy Gujarati, Parsi and Bhatia businessmen have invested huge capitals in the cotton textile industry. Apart from this, Mumbai being the ‘financial capital’ of India is advantageous in terms of acquiring capital for the cotton textile industry.
Easy availability of labour: Abundant supply of skilled and cheap labour is found in the Mumbai-Ahmedabad region as this region is densely populated.
Infrastructure: Suitable infrastructure required for the development of cotton textile industry is available here which has helped the industry flourish.
High demand: There is a huge demand for cotton clothes in our country because of the large population. Also, high demand of cotton fabric in foreign markets has helped this industry grow.

3. Discuss the problems of cotton textile industry in India and their remedial solutions.

Ans. The problems of cotton textile industry are discussed below-

Lack of raw materials: Long staple cotton (suitable for making best quality cotton fabric) is not available in adequate quantities in India.
High cost of production: Long staple cotton is imported from different countries which has led to an increase in the production cost.
Old machineries: Most of the cotton textile. industries have old and outdated machineries which produce low quality fabric. This has ultimately led to high cost of production.
Stiff competition in the global market: Sale of cotton fabrics from India is limited in the European countries. India also faces stiff competition from other countries in selling cotton fabric to the global market.
Competition with synthetic fibres: Synthetic fibres such as rayon, nylon, polyester, acrylic are popularly used nowadays to make different fabrics. This has, to some extent, decreased the demand of cotton fabric.
Irregular power supply: Sometimes inadequate power supply to the cotton textile mills hampers the production.

The remedial solutions of the problems faced by cotton textile industry in India are as follows-

Modernisation of the industry: The Government of India has set up the Textile Modernisation Fund which will help in replacing the old and outdated machineries with the advanced ones and implement modern technologies in the production process.
Cultivation of long staple cotton: To reduce the import of long staple cotton from other countries, it is being cultivated in the north-western region of India with the help of irrigation.
Reduction in excise duty: As per the recommendation of the Joshi Committee, the government has reduced the excise duty on cotton-based commodities.
Use of automated power looms: Fully automated power looms are being used nowadays in order to increase the rate of production and reduce the price of the finished product.
Establishment of the Cotton Textile Export Promotion Council: The Cotton Textile Export Promotion Council has been established in order to facilitate the export of cotton-based commodities.
Establishment of research institutes: of Many research institutes like Ahmedabad Textile Research Association, Mumbai Textile Research Association and South India Textile Research Association have been set up to focus on the betterment of the cotton fabrics.
Establishment of the National Textile Corporation: The National Textile Corporation (NTC) has been established to revive the sick cotton industries by introducing new machineries and advanced technology.

4. Briefly discuss the causes that have influenced the development of cotton textile industry in India.

Ans. The cotton textile industry in India is a flourishing industry and there are at present, many cotton textile mills distributed all over the country. Cotton textile industries in India can be divided into four categories on the basis of their location- 1. Western region, 2. Southern region, 3. Northern region and 4. Eastern region. The causes that have influenced the development of cotton textile industries in these regions are discussed below-

Availability of raw materials: Adequate amount of cotton is grown in the black soil region of India which is used as the raw material in the cotton textile industry. Apart from this, the southern states of India have taken initiative to start the cultivation of long and very long staple cotton.
Humid climate: Hot and humid climate prevail in the states of peninsular India, especially the southern states which is highly favourable for cotton cultivation. This type of climate also helps in cutting the yarns. Nowadays, humid atmosphere is artificially created in the factories using humidifiers.
Easy power supply: A number of thermal power plants and hydel power plants have been established in this region in post- independent India. These power plants supply the requisite power to the cotton textile industries. Example-Ukai, Koyna in western India; Hirakud, Talcher, Bandel in eastern India; Bhakra-Nangal, Rihand, Bhatinda in northern India; Mettur, Sivasamudram, Nagarjunasagar in southern India.
Proximity to ports: The raw materials are imported and the finished products are exported through the various ports situated close to the cotton textile mills. Example-Mumbai, Kandla (west coast of India); New Mangalore, Kochi, Chennai (south coast of India); Visakhapatnam, Kolkata, Haldia (east coast of India).
Well-connected transport system: Numerous railway lines, national highways and other important roads have been linked in such a way that a well-connected transport system has developed in India. Thus, it has become easy to collect the raw materials from different parts of the country and distribute the finished products all over the country.
Capital: Wealthy businessmen from the Parsi, Bhatia and Gujarati communities as well as several government and non-governmental organisations have invested huge capital in the cotton textile industries of India.
Cheap labour: India is a highly populated country. Thus availability of cheap and skilled labour is a favourable factor that promotes the development of cotton textile industries in India.
High demand: There is a huge demand for cotton fabrics in both national and international markets. This has helped in the development of the cotton textile industry in India.

The petrochemical industrial centres including the refineries have grown in proximity to the ports in order to save the cost in transporting crude petroleum to the refineries (from oil tankers that bring petroleum to our country from foreign lands) and sending the finished products to the port for exporting.

33. What is meant by engineering industry?

Ans. The industries which mainly use different metals as raw materials, specially iron and steel to manufacture various instruments, machineries and appliances are called engineering industries. Engineering industries can be of two types-1. Heavy engineering industries (like automobile industry) and 2. Light engineering industries (like wrist watch industry).

34. Why is the petrochemical industry known as the ‘sunrise industry’?

Ans. The importance of petrochemical industry is growing day-by-day as both the refined petroleum (the major finished product) and other by-products of this industry have immense use in our lives. The by-products are extensively used as raw materials in other industries. So, the petrochemical industry helps in the development of several other industries and itself is emerging as a fast-progressing industry. Thus, it is known as the ‘sunrise industry’.

Population of India

Long Answer Type Questions

1. Why distribution of population density not equal all over India?

OR, Discuss the reasons of uneven distribution of population of different regions in India.

OR, Discuss the geographical causes of unequal distribution of population density in India.

Ans. The distribution of population density is not equal throughout the India. In some regions there is a very high concentration of people while in some regions it is sparse. The main causes of this uneven distribution of population density in India are-

1. Physical causes

Topography: The mountainous regions of India in the north, north-east and in the southern states have very rugged and rough topography. These areas have less population. On the other hand, the Northern Plains and the Coastal Plains have gentle topography that support agriculture, industrial development, and other economic activities. These areas have high density of population.
Climate: India broadly enjoys tropical monsoon climate. Climatic conditions over the Northern Plains, coastal regions and the Peninsular Plateau is moderate and suitable for living. These areas have high population densities. On the other hand, dry and harsh climate in the Kutch region of Gujarat, desert region of Rajasthan and the severe cold climate in the Himalayan mountainous region repel population concentration.
Rivers: High concentrations of population are found in the river valleys of the Ganga, Indus, Brahmaputra in the north and the Mahanadi, Godavari, Krishna, Kaveri, etc., in the south. This is because the rivers provide water for drinking, irrigation, navigation, pisciculture, hydroelectric power generation, etc. They also help to spread fertile alluvial soil for agriculture.
Soil: The regions having rich fertile soils densely populatd than the infertile regions. E.g. Alluvial soil of the river valleys and the rich black soil of the Deccan plateau region attract huge concentrations of population for agriculture.
Forests: Presence of dense forests in the foothills of the Himalayas and the western slope of the Western Ghats lead to a low density of population in these regions.
Mineral resources: Presence of mineral resources lead to the development of industries and provide employment to a huge population. Hence, the presence of huge reserves of mineral resources in the Chota Nagpur region and other adjoining regions have a huge density of population.

2. Economic causes

Transport and communication: The plains of northern India are suitable for the construction of roadways, railways and other means of transport. Thus, these regions are highly populated. Transport system has a remarkable impact upon population movement and distribution.
Industries: Development of industries provide employment to a huge number of people. Hence, the industrial areas like Durgapur, Asansol, Jamshedpur, etc., are densely populated.

3. Others: Population may concentrate in some regions for certain special reasons. E.g.

Tourism: Darjeeling, Srinagar
Medical treatment: Vellore, Chennai
Historical places: Lucknow, Agra, Delhi, Mahabalipuram
Education: Shantiniketan, Nalanda, Aligarh
Religious centres: Ajmer, Varanasi, Puri
Military bases: Gwalior
Administrative centres: Delhi, Kolkata
Temporary Migration: Kolkata, Delhi, Joshimath
Communication centres: Nagpur

2. Describe the different regions of India according to the distribution ofpopulation.

Ans. The distribution of population in India is influenced by topography, rivers, soil, climate, etc. of the different parts of the country. According to the distribution of population, India can be classified into four regions-

The riverine plains of north India: The Indus-Ganga-Brahmaputra plains of north India is the most populated region of India. The causes of high concentrations of population in this region are-gentle topography, rich fertile alluvial soil, perennial rivers, sufficient rainfall, moderate tempera- ture, etc. These help in the development of agriculture, industries, and cause urbanisation. The states of Uttar Pradesh, Bihar and West Bengal lie in this region.
The eastern and western coastal plains: The coastal plains along the eastern and western margins of the Indian peninsula is the second most highly populated region of India. This is due to the presence of fertile soil, agricultural and industrial development, trade and commerce, development of transport facilities, etc. The Eastern Coastal Plains are gentler and wider than the Western Coastal Plains. Density of population is higher in the Eastern Coastal Plains than the Western Coastal Plains. Many ports like Mumbai, Chennai, Visakhapatnam and Kochi have been built in this region.
Deccan plateau region: This region is mainly rich in mineral resources. But some ports are highly suitable for agriculture as well due to presence of fertile black soil. Medium density of population is found in the states of Maharashtra, Karnataka, Tamil Nadu, and Andhra Pradesh.
Mountainous, desert and forest regions: The Himalayan mountainous region, the eastern mountainous region, Meghalaya plateau, Marusthali of Rajasthan, forest regions of Madhya Pradesh, Chattisgarh and Odisha have very less density of population. Rugged terrain, infertile soil, very less rainfall, presence of forest, absence of vegetation in these regions make them less densely populated. Jammu and Kashmir, Himachal Pradesh, Arunachal Pradesh, Sikkim, Uttarakhand and the states of north- east India fall under this category.

3. Discuss the various favourable conditions that lead to the gradual development of towns and cities.

Or, Discuss the causes of Urbanisation in India.

Ans. The favourable conditions that gradually lead to the formation of towns and cities are-

Administrative centres: If a place is found suitable for administrative works, several educational, business and trade and other service centres develop around it. This leads to development of roads, buildings and concentration of population. Thus a town is formed, which may grow into a big city. E.g. Chandigarh, Bhopal, Gandhinagar, etc.
Mineral resources: Availability of mineral resources in certain regions attract population due to provision of employment in the mines and industries and related sectors. These centres gradually grow into large towns and cities. E.g. Asansol, Dhanbad, etc.
Industrial centres: The regions where industries have developed, attract population due to availability of employment. E.g. Jamshedpur, Bhilai, etc.
Business centres: The places where consumer goods are accumulated for business and trade, develop as business centres. The buyers and sellers gather in the same place leading to huge concentration of population. E.g. Hisar in Haryana, Hapur in Uttar Pradesh, etc.
Communication centres: The places where the different modes of transport and communication are available, which help to develop big towns and cities as there is a large accumulation of population. E.g. Siliguri, Kharagpur, etc.
Pilgrimage centres: Pilgrimage centres like Haridwar, Varanasi, Gaya, Mathura and Brindavan have gradually developed into large towns and cities.
Educational and cultural centres: Places like Shantiniketan, Aligarh, Varanasi have emerged as educational and cultural centres and have grown into big cities.
Historical places: Concentration of high population in the historical places lead to the development of towns and cities in those regions. E.g. Agra, Murshidabad, etc.
Tourist spots: The scenic beauty and marvellous landscapes of some regions lead them to develop into attractive tourist spots. Thus they grow into towns and cities. E.g. Darjeeling, Digha, etc.
Military centres: Some military centres have grown into towns and cities. E.g. Meerut, Barrackpore, etc.
Ports: Towns and cities have developed around important ports. E.g. Paradweep, Haldia, etc.
Junction of mountainous and plain lands: Places like Haridwar has developed as a town due to its physical location at the junction of the mountainous and plain lands.
In a nutshell, it can be said that in the long run a combination of numerous factors lead to the formation of a town or a city.

4. What are the problems of urbanisation in India?

Ans. Urbanisation is the process of conversion of rural regions into urban regions like towns and cities. The various problems of urbanisation in India are-

Unplanned urbanisation: The rapid increase in the population of India has led to rapid and unplanned urbanisation. Agricultural fields, forest lands and fallow lands have been quickly converted into urban regions. Unplanned growth of towns lead to construction of narrow streets, poor drainage systems, scarcity of drinking water and unhealthy conditions of living.
Preference of people to move from rural to urban centres: The smooth and luxurious lifestyle of towns and cities attract a huge population from rural areas to come and settle in urban areas. A huge number of rural people flow towards urban centres due to attraction of employment, high standards of living and a fascinating lifestyle. Thus towns and cities develop.
Lack of space: Inflow of population in urban centres result in lack of space for proper accommodation. Thus slums develop adjacent to railway lines, canal sides and along busy roads. E.g. Problems of slums are predominant in cities like Mumbai and Kolkata.
Traffic problems: Unplanned growth of towns lead to formation of narrow streets and shortage of footpaths. This leads to traffic congestions and frequent jams on the roads of towns and cities.
Degradation of the environment: Development of towns and cities lead to industrialisation and excessive use of motor vehicles. This leads to high levels of pollution and spread of diseases due to disposal of wastes in canals, fields and in street corners.
Lack of proper education medical and other facilities: Due to urbanisation there is an overcrowding occurring in the educational institution and hospitals, which affects the quality of education and health together.
Power supply: Unplanned development of towns lead to unplanned use of power resources, which lead to a disbalance between production and demand for power supply in a town or city.
Drainage problems: Unplanned urbanisation leads to drainage problems in towns and cities. Disposal of wastes and plastics in drainage canals lead to blockages and water logging in towns and cities even after a little rain. Also, the rapid growth of insects and pests in the drainage lines result in occurrence of diseases and health hazards.

Short Explanatory Answer Type Questions

1. What are the causes of increase in population of India?

OR, Discuss the causes leading to rapid increase of population in India.

Ans. The population of India has increased rapidly over the last few decades. The causes for this increase of population are-

High birth rate: Birth rate in India is very high. In 2011, birth rate in India was 21.8 people per 1000 persons. Lack of education and consciousness, poverty, superstitions, religious beliefs, child marriage, etc., are responsible for this.
Low death rate: In the last few decades, death rates have minimised considerably due to major development in medical facilities and general health of people. Also, development of transport and communication systems played a crucial role in this context. These facilitates in reaching the places affected by flood, drought or natural disasters as well as helped in providing relief and rescue the casualties. In 2011, death rate in India was only 7.1 persons per 1000 persons.In
Immigration: The rapid migration of refuges from the neighbouring countries, especially after the partition of the country, has increased the total population of India rapidly all of a sudden.
Economic development: The increase in the production of agricultural and industrial goods over the last few decades helped to improve the economic conditions of the people. Thus total population has increased considerably.
Science and technology: Advancement in science and technology has made an overall improvement in the conditions of living. Moreover, forecast of disasters and climatic hazards before hand has made it possible to become alert and take necessary steps to save life and property. These also contribute to increase the total population.

2. Why does Himachal Pradesh lie in the category of low population density zone?

Ans. Himachal Pradesh is a state in India with a low population density. According to the 2011 Census, the total population of the state was only 68,56,509 people and population density was only 123 persons per sq.km. The causes for low density of population in this state are listed below-

Rugged topography: The topography or landform of Himachal Pradesh is mostly rugged and hilly. This indicates a lack of availability of agricultural land and also difficulty for people to build houses in the region.
Infertile soil: The land being rugged and hilly, the soil is immature and not so fertile. This soil is not suitable for good agriculture.
Climate: The climate of Himachal Pradesh is generally cold, with chilling and harsh winters. This is not a suitable climate for settlement of a large population.
Lack of raw materials for industries: Lack of mineral resources as raw materials for industries have left the place with very low growth of industries.
Lack of power resources: Lack of power resources has hindered the growth of mineral as well as agro-based industries.
Poor transport and communication system: Poor transport and communication system also keep the state devoid of high population concentrations.

3. Discuss the trend in increase of population in India.

Ans. India is the second most populated country of the world. Rate of increase in population of India was quite low in the pre- independence period, but it started rising rapidly in the post-independence period. The total population increased from 23.84 crore in 1901 to about 36.11 crore in 1951. That means, the total increase in population of India in the first half of the 20th century was 12.27 crore. The rate of increase in population or the growth rate of population was quite low during this time, the lowest being -0.31% (1911-1921) and the highest being 14.22% (1931-1941). In the second half of the 20th century, population increased from 36.11 crore in 1951 to 102.9 crore in 2001. The total increase in population was 66.79 crore. The growth rate of population was also very high during this period, the lowest being 21.64% (1951-1961) and the highest being 24.79% (1961-1971). Between 2001-2011, the population of India increased by 18.15 crore and counted to 121.02 crore in total. The rate of increase in population was 17.64%. As a matter of fact, the increase in population of India between 1991 and 2001, is higher than the total population of the neighbouring country of Pakistan (world’s 7th largest populated country). This shows very clearly that the total population of India is increasing very rapidly decade by decade.

4. What are the causes of high density of population in India?

Ans. India is the second most populated country of the world (after China). According to the census of 2011, the total population of India is about 121 crore 2 lakh. Population density is 382 people per sq.km. The causes of high density of population in India are-

Presence of plain lands: The northern plains and coastal plains of India are suitable for agriculture, transport, industrialisation, etc. Hence, these areas encourage high density of population as compared to mountain region.
Climate: Most of the regions of India are influenced by tropical monsoon climate. The hot and humid weather over the plains is suitable for agriculture, industrialisation and other economic activities. Hence, high density of population are seen here.
Fertile soil: The plain lands of India are mostly formed by deposition of fertile alluvial soil brought down by numerous rivers. It helps in development of agriculture and supports higher population density.
Availability of water: The rivers of India supply water for irrigation, hydroelectric power generation, pisciculture, water transport, etc. Hence, the river valleys are densely populated.
Economic causes: The regions which are rich in mineral resources promote the growth of industries and provide employment to a huge number of people. Hence, these areas also are highly populated.

5. Discuss the main characteristics of population distribution in India according to the Census of 2011.

Ans. The main characteristics of population distribution in India according to the 2011 Census are-

Uttar Pradesh is the most populated state of the country. (19 crore 96 lakh people)
Sikkim is the least populated state of the country. (6 lakh 8 thousand people)
Population of the national capital of Delhi is 1 crore 68 lakh and that of the Union Territory of Puducherry is 12 lakh 44 thousand.
West Bengal is the fourth most populated state. (9 crore 13 lakh people)
About 1/3rd of the Indian population lived in the fertile Northern Plains or the Gangetic Plains. This area is about 1/9th of the total area of the country.
The desert region of Rajasthan and the mountainous regions of the Himalayas are the regions of very scanty population.
31.2% of the total population of India reside in urban areas while about 68.8% reside in rural areas.

6. Discuss the main characteristics of the density of population of India according to the census of 2011.

Ans. The main characteristics of the density of population of India according to the Census of 2011 are-

Population density of India in the year 2011 was 382 people per sq.km.
Bihar is the most densely populated state of India (1,102 persons per sq.km).
Arunachal Pradesh has the lowest density of population (17 person per sq.km)
Amongst the Union Territories, the highest density of population is noticed in Delhi (11,297 persons per sq.km). Chandigarh has a population density of 9,252 persons per sq.km. The lowest density of population is noticed in Andaman and Nicobar Islands (46 persons per sq.km).

7. Why does Arunachal Pradesh have the lowest density of population in India?

Ans. Arunachal Pradesh has the lowest density of population amongst all the states and Union Territories of India. The reasons for this low density of population in this region are-

Topography: The general topography of Arunachal Pradesh is rugged and mountainous. It is difficult to carry out any economic activity over here.
Infertile soil: The mountainous and sloping land has immature and less fertile soil, which is not suitable for agriculture.
Climate: Climate here is both cold in the higher altitudes and humid in the lower altitudes with very cold winters. Such conditions are not suitable for economic activities and living.
Dense forests: The hill slopes of this region are covered with dense forests, which are filled with wild animals. This is not suitable condition for dense population.
Raw materials for industries: Industries have not developed here due to lack of both minerals and agricultural raw materials. Few small scale and cottage industries can be seen here.
Power resources: Non-availability of power resources have also hindered the growth of large industries in this region.
Transport and communication: Transport and communication system is not developed in this region due to the rugged terrain. Hence, development of economic activities is hindered, which in turn fails to attract a large population.

8. ‘The Himalayan mountainous region of India is sparsely populated’-State the geographical reasons for this.

Ans. The Himalayan mountainous region has very low or sparse population. Here the average density of population is around 100 people per sq.km. The causes of such sparse population in the region are-

Rugged topography: The whole region is mountainous and have rugged topography. It is difficult to carry out any economic activity over here.
Infertile soil: The region has mountain soil which is less fertile and not quite suitable for agriculture.
Harsh climate: The Himalayan region experiences cold weather all through the year and very harsh winters. Such climate is not suitable for the settlement of population.
Dense forests: About 90% of the Himalayan region, especially the sloping lands are covered with dense forests, which have influenced the population densities in these areas.
Transport and communication systems: The rugged terrain and harsh cold climate prevented the development of good transport and communication system. Most of the forest regions are inaccessible. Hence, density of population has remained low.
Lack of raw materials: The Himalayan region lacks mineral resources that can be used as raw materials in industries. Whatever minerals are found here, is difficult to be excavated due to rugged terrain. Lack of agriculture results in lack of agro-based industries. The forest-based raw materials are also difficult to be utilised. Hence, there is a lack of industrial development in this region.
Lack of power resources: Lack of power resources also hinder the development of industries. All these together hinder the settlement of huge population in this region.

9. Why is the Gangetic Plains of India highly populated?

Ans. The Gangetic Plains or the Northern Plains of India is the highest populated region of the country. Average population density here is more than 500 people per sq.km. The causes for the high concentration of population in this region are-

Plain land: The topography of the region is a plain land with almost no ruggedness. This is suitable for agriculture, industrialisation, development of transport and communication and other economic activities.
Climate: The moderate temperature and rainfall of the Gangetic Plains are highly suitable for agriculture in the region. This also provides suitable conditions of living.
Soil: The Northern Plains is covered with rich fertile alluvial soil brought down by the Ganga and its tributaries. This soil is highly suitable for cultivation of crops, especially rice, wheat, jute, sugarcane and oilseeds.
Transport and communication: The plain nature of the land helps in development of roadways, railways and other means of transport and communication. This results in high population density in the region.
Power resources: A number of thermal power and hydel power stations have been established here which provide the necessary power supply for industrialisation, agriculture as well as livelihood.

All these factors together help to result in a high concentration of population in the Gangetic Plains.

10. ‘Social and political stability of a region influence population density’.-Explain.

Ans. Social and political stability of a region are two important factors that influence the population density of a region.

Social conditions: The social conditions can be categorically viewed as religious and cultural conditions. Religious causes may lead to in-migration or out-migration of population that influences the population density of the region. Cultural developments like spread of education, vocational trainings, scientific outlook and technological development help to discover new resources and hence attract population.
Political conditions: People prefer to settle in the places where there is political stability. E.g. during 1947, after India’s independence and partition of Bengal, a severe political disturbance was seen in the eastern part of Bengal, which later came to be known as Bangladesh. On the other hand, political conditions were better in the western part of Bengal. Hence, huge influx of refuges resulted in Bengal, Tripura and the nearby states. This resulted in high density of population in the region.

11. What are the causes of reduction of death rates in India in the post-independence period?

Ans. The average death rate in India in the pre-independence period was about 30 per 1000 persons, which reduced to about 7.1 per 1000 persons in 2011. The causes of reduction of death rates are-

Medical facilities: Development of medical facilities in the post-independence period led to improve health conditions of people. Thus it influenced to reduce the death rates.
Standard of living: Availability of nutritious food and proper medical treatments helped to reduce death rates.
Education and health consciousness: Increase in education of the people increased consciousness about health, which helped to control diseases and the rate of death.
Superstitions: Previously people used to take diseased people to witch doctors and other places for treatment due to superstitions and lack of knowledge. But nowadays, they became aware of latest medical facilities and take the diseased people to doctors and hospitals.

12. Discuss the influence of rivers on the disparity in distribution of population in India.

Ans. Water is a basic requirement of living. It is noticed that all major civilisations of the world came up along the banks of large rivers. In India, large population are seen in the valleys of the major rivers like Ganga, Indus, Brahmaputra, Mahanadi, Godavari, Krishna and Kaveri. The causes of high density of population in the river valleys are-

Rivers provide the water necessary for drinking, bathing, washing, cooking, etc.
Rivers provide water for irrigation.
Rivers carry and spread alluvial soil on the adjacent lands and make them fertile and highly suitable for agriculture.
Rivers are used for water transport.
Rivers help in production of hydroelectric power.
Fish cultivation or pisciculture can be done in rivers.
Rivers design the drainage system of an area and ensure availability of water for various purposes.

13. What are the causes of high birth rate in India?

Ans. The birth rate in India is quite high compared to the other countries of the world. In 2011, the birth rate was high as 21.8 persons per 1000 persons. The causes of high birth rate in India are-

Low literacy rate: In India, about 26% of the population is still illiterate. They have not understood the pros and cons of the increasing population of the country.
Child marriage: Early marriage is one of the major cause for the high birth rate.This generally leads to larger number of children being born. Thus, results in high birth rate.
Religious causes: Religious beliefs and superstitions stop the people from using preventive measures of birth control. Also many people believe that more number of children means more blessings of the God.
Social status of women: In a country like India, where patriarchy prevails, women have a low social status. Often they cannot even voice their wish of birth control due to pressures from family and society.
Lack of social awareness: There is a lack of consciousness and awareness among the people of India regarding the consequences of the huge increase in population and the need of birth control.
Lack of government policies: The government has not yet taken up enough initiatives to spread the consequences of rapidly increasing population. Whatever policies have been taken up till date have not given satisfactory results due to lack of execution.
High death rates: In some cases, high death rates in some regions of the country indirectly initiate high birth rates.
Demand for a male child: Even in the 21st century, a male child in the family is seen as a boon.

14. Is India a highly populated country?

OR, Why is India designated as a highly populated country?

Ans. India ranks second in the world with respect to the total population of the country (after China). By the census of 2011, the total population of India was 121 crore 1 lakh 93 thousand 422 people. About 17.5% of the total population of the world reside in India. That means, there is an Indian in very 6 people in the world. But India occupies only 2.42% of the total land surface of the world. This indicates that there is a high pressure of population on land in India. It can be mentioned that, although the population of China in 2011 was about 134 crore, i.e., 13 crore people more than that of India, it does not suffer from tremendous population pressure like India as total area of China is about three times that of India.

Not only the total population, but the rate of increase in population in India per year is also very high. The rate of increase in population in India in 2011 was 17.64%, whereas in case of China was only 5.6%. During 2001-2011, population of India increased by more than 18 crore, i.e., more than 1.80 crore per year. All these facts help to prove that India is definitely a highly populated country with tremendous pressure of population on land.

15. What are the problems of the rapidly increasing population in India?

Ans. The problems caused by the rapidly increasing population in India are-

High price of food crops: The rate of increase in population in India is much higher than the rate of increase of food crop production. Hence, due to excessive demand of food crops, the price of food crops goes up at a high rate.
Problems of settlement: The rate of increase in population in India giving rise to space problems. There is huge demand of space available for the construction of building, houses ,etc. Infact, accommodations in large towns and cities have become too much costly.
Unemployment: Increase in population leads to increase in number of unskilled and uneducated people. This further leads to problems of unemployment.
Medical facilities: Medical facilities are inadequate for this rapidly increasing population. Many people die due to lack of hospitals and health centres, lack of doctors and medicines.

16. What is the relation of sustainable development with increase in population?

Ans. Sustainable development refers to that kind of development where the basic needs of the population can be met and their welfare can be continued in the long run by the judicious use of available resources. The major factors of sustainable development are-1. Social welfare, 2. Economic upliftment, 3. Cultural prosperity, 4. Ecological balance, 5. Improvement of geographical conditions. In a country like India, where the population is increasing in leaps and bounds, a persistant condition of poverty and distress will follow, if sustainable development is not given enough importance.

Rapid growth of population exerts pressure on sustainable development. For example, increase in population influences the quality and quantity of components like water, air, power resources, ecosystem, food crops, nutrition levels, mineral resources, etc. The levels of pollution and wastes are also high. Infact, it is estimated that if the population goes on increasing at this alarming rate, the mass of the whole population of the world will be equal to the mass of the earth itself by the next 5000 years.

In 1951, the population of India was about 36.11 crores. At that time production of rice was about 3.46 crore tonnes, production of wheat was about 0.64 crore tonnes, amount of irrigated land was 2.7 crore hectares. According to census 2011, the population of India was 121.02 crore. At that time, production of rice rose to 15 crore tonnes, production of wheat rose to 8.68 crore tonnes, and amount of irrigated land rose to 10.4 crore hectares. Thus, we see that a remarkable growth in the production of food grains is seen through the decades with the rapid rise in population. This is an example of sustainable development.

9. How does an urban centre develop as an ‘administrative centre’?

Ans. Some urban centres may be found to be at such a location that they help in carrying out administrative works. These centres grow into administrative centres by the virtue of their location. These centres gradually attract people and grow into small towns. These small towns grow into large towns and then into big cities gradually. E.g. Delhi and Kolkata have grown as administrative centres for their locations.

10. How does transport and communication help in developing an urban centre?

Ans. The places with well developed transport and communication systems are easily accessible and hence people are attracted to work and live there. Thus large urban centres may develop. E.g. Siliguri has grown as a big town due to the good network of roadways and railways. It is the doorway to the north-eastern states of India as well as to Nepal, Bhutan and Bangladesh.

11. How does growth of industries help in the development of towns?

Ans. Development of industries provide employment to a huge population. This leads to the dense collection of a population in the surrounding areas. This helps in the development of large towns in the industrial areas. E.g. Jamshedpur, Durgapur, Ahmedabad, etc.

12. Mention two problems of urbanisation in India.

Ans. Two problems of urbanisation in India are-

Health hazards: The pollution caused by industries, motor vehicles, etc., create unhealthy conditions in the urban areas which may cause health hazards in the long-run.
Traffic jams: The huge number of vehicles plying in the cities, the encroaching of footpaths by shops and stalls, etc., altogether lead to very slow traffic movement. This creates frequent traffic jams.

13. What do you mean by rapid increase of population?

Ans. The positive increase of population in leaps and bounds over a small period of time is known as rapid increase in population. This is also known as ‘Population explosion’. In India, a huge increase in the size of population was noticed between 1951 and 1981 (2.16% to 2.47% every year). This rapid increase led to the condition of population explosion. Development of education, medical facilities, agriculture, industries and standard of living, etc., are responsible for this condition.

14. What do you mean by the ‘stagnation or stationary phase of population growth’?

Ans. When the population of a region does not change but remain constant over a period of time, it is known as ‘stagnation of population growth’. This may happen when the positive increase of population is balanced by the negative increase of population. E.g.

Stagnation of population= Birth rate + In- migration = Death rate + Out-migration.

Stagnation of population can be seen in Sweden and Switzerland.

Transport and Communication System in India

Long Answer Type Questions

1. Discuss the importance of transportation system.

Ans. Transportation system is very important for the socio-economic and political development of the country.

1. Economic importance

Exchange of goods: Transportation system helps in exchange of goods between countries. Example-India exports tea, jute, spices and several other items to the world market and imports necessary goods from different countries.
Decentralisation of industries: Transportation system helps in the decentralisation of industries. Raw materials and finished products can be transported to the factory and market respectively and the industries can be located at locations that incur minimum costs.
Hazard management: Transportation system helps in the rescue of victims and distribution of relief and medical aid in times of hazards like floods, droughts, earthquakes or tsunamis.
Development of agriculture: Transportation system helps to transport necessary seeds, fertilisers and agricultural equipments from towns to rural areas. It also helps to transport agricultural products to the markets and the agro-based industries in the urban areas.
Collection of natural resources: Collection of forest resources, mineral resources and animal resources largely depend upon the transportation system. E.g.-Dense forest of the Amazon basin and northern Canada have yet remained unexplored due to lack of development of transportation system.
Balance in price of goods and commodities: The transportation system helps to carry various commodities to the markets all over India. Hence, availability of the commodity can be ensured and the price can be kept at par all over the country.

Short Explanatory Answer Type Questions

1. List the advantages of road transport.

Ans. The advantages of road transport are-

Speed: Light and less bulky commodities can be easily transported via roadways and at greater speed.
Anytime transportation: Road transport does not have to depend on a fixed schedule as rail and air transport. They can be availed at any time of the day as per need.
Security: Roadways are used to provide security in border regions of the country. They are also used for transporting food, medical aids, war equipments, etc., to the border areas.
Variety of vehicles: A number of vehicles can ply over the same roadway. E.g.- Buses, trucks, cycles, auto rickshaws, etc., can use the same road and carry different types of commodities and varied volumes of passengers.
Easiest transport: Roadways provide the easiest mode of transport for movement of raw materials to production areas and carry the finished products to markets.
Door to door transport: Roadways help in the door to door transportation of goods and passengers.

2. What are the disadvantages of road transport?

Ans. The disadvantages of road transport are-

Cost of construction: Cost of construction of roads is quite high and the process is also time consuming. Roadways cannot be developed properly unless the country has a stable and developed economic condition.
High maintenance cost: Roadways are prone to damage due to rainfall, flood, snowfall and even due to plying of heavy loaded vehicles on a regular basis. Hence, they require regular monitoring and maintenance. This incurs high costs.
Lack of bridges hamper roadways: India is a land of numerous rivers spreading like a network all over the land. Lack of bridges over these rivers hamper the spread of roadways in these regions.
High cost of transportation: Transportation of goods as well as passengers by road is comparatively costlier than transportation by rail and waterways. The high cost of transportation through roadways creates an impediment for sure.
Lack of comfort: Journey by road over long distances is tedious and less comfortable than journey by rail. Hence, passengers tend to avoid road for long distance journeys.

3. Write a short note on the Golden Quadrilateral, the East-West and North-South Corridors.

Ans. Golden Quadrilateral: The Golden Quadrilateral is a National Highway project taken up with the aim of connecting the four metropolitan cities of India, namely, Kolkata, Delhi, Mumbai and Chennai. This is the largest national highway project of India and the fifth largest of the world. Under this project, 5846 km of roadways have been built by the National Highway Development Project (NHDP). The length of roads between the metropolitan cities are-1. Delhi to Kolkata-1453 km, 2. Chennai to Mumbai-1290 km, 3. Kolkata to Chennai-1684 km, 4. Mumbai to Delhi-1419 km (Source: NHAI) These highways are of 4-6 lanes and form the backbone of the transportation system of India. The project has been executed with the help of modern technology and advanced equipments imported from Malaysia.

North-South and East-West Corridors: The North-South Corridor of India extends from Srinagar of Jammu and Kashmir in the north to Kanyakumari of Tamil Nadu in the south. This is an important highway spreading for 4000 km, that connects the extreme northern and southern regions of the country. The East-West corridor extends from Silchar of Assam in the east to Porbander of Gujarat in the west. This 3300 km long highway connects the extreme eastern and western regions of India. Presently, these corridors are the largest among the running roadway projects in India. These are managed by the National Highways Authority of India.

4. Discuss the importance of road transport in the economic development of India.

Ans. Road transportation system plays a very important role in the economy of a developing country like India. The importance of roadways in the economic development of India are-

Development of rural areas: About 69% of the population of India live in rural areas. Roads help in the transportation of agricultural products from rural to urban areas and promote intra-regional trade and commerce. Roads also help in transporting fertilisers, insecticides and modern agricultural equipments from towns and cities to rural areas for the development of agriculture.
Raw materials: Roadways help in acquiring raw materials, both agro-based and mineral-based from different regions for development of industries. E.g.-Coal from Raniganj and Asansol regions is transported to the Hooghly industrial region through the National Highway NH-19.
Development of hilly areas: The hilly regions of northern India, north-eastern India and the Deccan plateau regions are not fit for the construction of railways. Hence, roadways are very important for the development of these regions. Also, beacuse of the rugged terrain and the absence of proper railway network in this region, roadways help to establish communication between different parts of this region.
Low cost of construction: Construction of roads incur lower cost than construction of railways. Hence, development of roadways put less pressure on the economy of the country.
Border security: The border areas of India have rugged terrain and harsh climatic conditions. Construction of railways is impossible in those regions. Hence, roadways are very important in these regions as they help to maintain and establish an environment of safety and security in the border regions of India.
Connection with small industrial centres: The large industrial regions of India are connected to the raw material regions as well as to the markets mostly through railways. But there are numerous small industrial centres in India which are dependent only on roadways for the supply of their raw materials and for their business and trade.

5. Name the different means of transport in India.

(1) Inland waterways, (2) Coastal waterways and (3) International waterways.

Airways is further sub-divided into-

(1) Domestic airways and (2) International airways.

6. What is the importance of National Highways?

Ans. National Highways are very important for transportation of goods across the lengths and breadths of India. Presently, the length of National Highways in India is about 96261 km. They spread through all the states like a network, providing road connectivity throughout the country. National Highways form only 2.91% of the total length of roadways in India. They help to transport about 40% of the total transport plying through roadways in the country. They are maintained by the central government of India. E.g.-1. Delhi and Kolkata are connected via the National Highway NH-19. 2. Kolkata and Mumbai are connected via the National Highway NH-6. 3. The longest National Highway of India is NH-44, that connects Srinagar in the north to Kanyakumari in the south.

7. Write a short note on the State Highways of India.

Ans. The State Highways are spread within particular states and help to connect with the National Highways. They are constructed and maintained by the state government. These roads generally connect the capitals of the states to the adjacent National Highways. They play an important role in transportation of goods and commodities, trade and commerce within the state. The total length of state highways in India is about 131899 km. E.g.-B.T. Road is a state highway in West Bengal.

8. What are border roads?

Ans. In the post-independence period, the ‘Border Roads Organisation’ was formed in 1960 for the construction of roads in the border regions of the country in order to provide security.

Time consuming: Railways in India ply in different gauges in different regions. Loading and unloading of goods and boarding and unboarding of passengers into different train coaches consume too much time and become costly.
Lack of modern technology: Indian railways lack the use of modern and advanced technology in signalling systems and train coordinations, so that all kinds of signalling problems and accidents due to head-on collisions can be controlled and avoided.
Lack of railway wagons: Lack of the required numbers of wagons for aboo transporting goods and commodities hamper trade and commerce activities. In many cases, people tend to depend more on road transportation than railways.
Journey without ticket: A huge number of people have a tendency of travelling in trains without ticket or paying less fare. Thus, the income of the railways from passengers is lowered and the railways incur huge loss due to this. Also, several malpractices are seen in transporting goods and commodities, which significantly reduce the income of the railways.
Lack of security of life and property: Train robberies, thefts and accidents show that there is lack of security of life and property in train journeys.
Lack of railway employees: Railways have been the organisation employing the highest number of employeess in India. But recently, this organisation is facing a dearth in number of employees due to irregular recruitments. Hence, the present employees are forced to work for longer hours.
