Primary Activities: The Base of the Economic Pyramid

Human activities that generate income are called economic activities, and they are broadly grouped into primary, secondary, tertiary and quaternary activities (NCERT, p. 22). Primary activities are directly dependent on the environment, because they refer to the utilisation of the earth’s resources — land, water, vegetation, building materials and minerals (NCERT, p. 22).

They include hunting and gathering, pastoral activities, fishing, forestry, agriculture, and mining and quarrying.

Think of an economy as a building. Primary activities are the ground floor — the only floor that directly touches the earth. Secondary activities process what the ground floor produces, tertiary activities serve it, and quaternary activities design the services. If the ground floor stops producing, every floor above is idle.

That is why this chapter is studied first: it is the base of the whole economic pyramid.

People engaged in primary activities are called red-collar workers, because of the outdoor nature of their work (NCERT, p. 22). The label is a memory anchor: primary work happens in fields, forests, pastures and mines, not in an office.

The chapter opens by asking why people in coastal regions fish while people in the plains farm. The frame for the answer is the definition itself: the physical environment decides which primary activity a region can practise, and social factors such as technology and capital then shape how it is practised.

The chain continues upward — the raw materials extracted here feed directly into Secondary Activities, where they are processed into goods.

Hunting and Gathering: The Oldest Economic Activity

The earliest human beings depended on their immediate environment for their food: they hunted animals, and gathered edible plants from the forests around them. People in very cold and extremely hot climates survived on hunting, while coastal communities took to fishing — which continues today, though modernised by technological progress (NCERT, p. 22).

Early hunters used primitive tools made of stones, twigs and arrows, so the number of animals killed was limited. Illegal hunting (poaching) has since made many species extinct or endangered — which is why the chapter leaves you the question of why hunting has been banned in India.

Gathering and hunting together are the oldest economic activity known. Gathering goes on in regions with harsh climatic conditions and often involves primitive societies extracting both plants and animals to satisfy needs for food, shelter and clothing. Its four markers:

• Capital: requires a small amount of capital investment.
• Technology: operates at a very low level of technology.
• Yield: yield per person is very low.
• Surplus: little or no surplus is produced (NCERT, p. 23).

The map and photo below show where and how gathering survives today:

Fig. 4.1 is a reminder that gathering is not only a prehistoric activity — in Mizoram, women still collect oranges from forests, and similar collection continues in tropical regions today. Subsistence gathering is practised in two sets of zones (NCERT, p. 23):

• High-latitude zones: northern Canada, northern Eurasia and southern Chile.
• Low-latitude zones: the Amazon Basin, tropical Africa, the northern fringe of Australia and the interior parts of Southeast Asia.

In modern times, some gathering is market-oriented and has become commercial. Gatherers collect valuable plants such as leaves, barks of trees and medicinal plants, process them simply, and sell the products.

The plant parts and their uses (NCERT, p. 23): bark supplies quinine, tanin extract and cork; leaves supply materials for beverages, drugs, cosmetics, fibres, thatch and fabrics; nuts provide food and oils; and the tree trunk yields rubber, balata, gums and resins.

A famous example sits in your pocket: the part of a chewing gum that remains after the flavour is gone is called chicle, made from the milky juice of the zapota tree (NCERT, p. 23). When the flavour fades, you are left holding a product of gathering.

Gathering has little chance of becoming important at the global level. Its products cannot compete in the world market, because synthetic substitutes — often of better quality and at lower prices — have replaced many items supplied by gatherers in tropical forests (NCERT, p. 24). Fig. 4.2, the distribution map for subsistence gathering, is read step by step in the map-reading section below.

Pastoralism: Two Ways of Rearing Animals

At some stage in history, humans realised that hunting is unsustainable and began domesticating animals. Depending on geographical factors and technological development, animal rearing today happens either at the subsistence level or at the commercial level (NCERT, p. 24).

Nomadic herding

Nomadic herding (or pastoral nomadism) is a primitive subsistence activity in which herders rely on animals for food, clothing, shelter, tools and transport. They move from place to place with their livestock, depending on the amount and quality of pastures and water, and each community occupies a well-identified territory as a matter of tradition.

Animal rearing varies by region (NCERT, p. 24):

Pastoral nomadism is associated with three important regions (NCERT, p. 24):

• The core region extends from the Atlantic shores of North Africa eastwards across the Arabian peninsula into Mongolia and Central China.
• The second region covers the tundra region of Eurasia.
• In the southern hemisphere there are small areas in South-west Africa and on the island of Madagascar.

Movement in search of pastures is undertaken either over vast horizontal distances or vertically from one elevation to another in mountainous regions. This vertical pattern has a precise name: transhumance — migration from plains to pastures on mountains during summers, and back from mountain pastures to plains during winters (NCERT, p. 24).

Fig. 4.3 captures transhumance in a single frame: sheep being taken up to the mountains at the onset of summer. When winter returns, the herders bring the animals back down to the plains.

In the Himalayas, Gujjars, Bakarwals, Gaddis and Bhotiyas practise this seasonal vertical movement; in the tundra, nomadic herders move south to north in summers and north to south in winters.

The number of pastoral nomads is decreasing and their areas are shrinking for two reasons: the imposition of political boundaries, and new settlement plans by different countries (NCERT, p. 24).

Commercial livestock rearing

Unlike nomadic herding, commercial livestock rearing is more organised and capital intensive. It is essentially associated with western cultures and is practised on permanent ranches. Its key features (NCERT, pp. 24-25):

• Ranches cover large areas divided into fenced parcels; when one parcel is grazed, animals are moved to another.
• The number of animals is kept according to the carrying capacity of the pasture — like a lift’s passenger limit, exceed it and the system stops working.
• It is a specialised activity — only one type of animal (sheep, cattle, goats, horses) is reared.
• Products such as meat, wool, hides and skin are processed and packed scientifically and exported to world markets.
• Rearing is organised on a scientific basis: breeding, genetic improvement, disease control and health care (NCERT, p. 25).

In northern Alaska, reindeer rearing shapes the local economy — most Eskimos there own about two-thirds of the stock. The important countries are New Zealand, Australia, Argentina, Uruguay and the United States of America (NCERT, p. 25).

Fig. 4.5, titled Commercial Livestock Rearing, shows animals raised on permanent ranch land — the organised setting that separates this activity from nomadic herding.

Comparison table — nomadic herding vs commercial livestock rearing (six criteria):

Fig. 4.4 (areas of nomadic herding) and Fig. 4.6 (areas of commercial livestock rearing) are read together in the map-reading section below — one map shows dry and cold belts, the other shows temperate New World and Australasian ranges.

Subsistence Agriculture: Shifting Cultivation and Intensive Farming

Agriculture is practised under multiple combinations of physical and socio-economic conditions, which gives rise to different agricultural systems (NCERT, p. 25). In subsistence agriculture, the farming area consumes all, or nearly all, of the products grown locally. It has two categories: primitive subsistence agriculture and intensive subsistence agriculture.

Primitive subsistence agriculture (shifting cultivation)

Shifting cultivation is the label for primitive subsistence agriculture, and tribes across the tropics still practise it — the main clusters are Africa, south and central America, and southeast Asia (NCERT, p. 25). How it works:

• The vegetation is cleared by fire, and the ashes add to the fertility of the soil — hence the name slash and burn agriculture.
• The cultivated patches are very small, and cultivation is done with primitive tools such as sticks and hoes.
• After about 3 to 5 years, the soil loses its fertility and the farmer shifts to another patch, clearing fresh forest for cultivation.
• The farmer may return to the earlier patch after some time.
• The major problem is that the cycle of jhum becomes shorter and shorter, because fertility is lost in different parcels (NCERT, p. 27).

Memory device — J-M-L: Jhuming, Milpa, Ladang — read the initials as Just Move Lands. That is exactly what shifting cultivators do: when a plot loses fertility, they just move to another patch of forest. Storing the idea with the initials fixes all three regional names in one step.

Intensive subsistence agriculture

This type is largely found in the densely populated regions of monsoon Asia. There are two types (NCERT, p. 27):

Type 1 — Wet paddy intensive subsistence agriculture. Dominated by the rice crop. Land holdings are very small because population density is high, so farmers work with family labour and the land is used intensively. Machinery use is limited and most operations are manual; farm yard manure maintains soil fertility.

The result is the chapter’s key contrast: high yield per unit area but low per-labour productivity.

Fig. 4.9 (rice transplantation) shows why wet-paddy farming is labour intensive: seedlings are transplanted into the field by hand. Many family workers cultivate a very small holding, so output per hectare is high while output per worker stays low.

Type 2 — Intensive subsistence agriculture with crops other than paddy. Because relief, climate and soil differ across monsoon Asia, paddy cannot be grown everywhere.

Wheat, soyabean, barley and sorghum are grown in northern China, Manchuria, North Korea and North Japan; in India, wheat is grown in the western parts of the Indo-Gangetic plains and millets in the dry parts of western and southern India. Most features match the wet-paddy type, except that irrigation is often used.

Fig. 4.7 maps the tropical belt of primitive subsistence agriculture, and Fig. 4.8 maps intensive subsistence farming in monsoon Asia; both are read step by step in the map-reading section.

Commercial Agriculture I: Plantation and Extensive Grain Cultivation

When Europeans colonised many parts of the world, they introduced profit-oriented, large-scale production systems — the plantations (NCERT, p. 28).

Plantation agriculture

Plantation agriculture was introduced by the Europeans in colonies situated in the tropics. Important plantation crops include tea, coffee, cocoa, rubber, cotton, oil palm, sugarcane, bananas and pineapples. Its characteristic features (NCERT, p. 28):

• Large estates or plantations.
• Large capital investment, with managerial and technical support.
• Scientific methods of cultivation and single-crop specialisation.
• Cheap labour.
• A good transport system linking estates to factories and markets for export.

The colonial origins are easy to remember as a table (NCERT, p. 28):

Fig. 4.10 shows a tea plantation on hill slopes. The chapter text gives the reason: slopes of hills are used for tea plantations because of favourable geographical conditions — the land drains well and the cooler slope climate suits the crop.

Today, ownership of the majority of plantations has passed into the hands of the government or the nationals of the countries concerned (NCERT, p. 28).

Extensive commercial grain cultivation

Extensive commercial grain cultivation is practised in the interior parts of semi-arid lands of the mid-latitudes, with wheat as the principal crop; corn, barley, oats and rye are also grown. The defining features (NCERT, pp. 28-29):

• Farm size is very large, so entire operations from ploughing to harvesting are mechanised. The chapter notes that combine crews can harvest grain over many hectares in a single day.
• It gives a low yield per acre but a high yield per person.

Why does this happen? The farm is so large and so fully mechanised that one worker cultivates a huge area, so output per person is high. But the land is worked extensively, with inputs spread over enormous acreages, so the yield per acre remains low.

The two phrases describe the same system from two sides: little per unit of land, a lot per unit of labour.

This agriculture is best developed in the Eurasian steppes, the Canadian and American Prairies, the Pampas of Argentina, the Velds of South Africa, the Australian Downs and the Canterbury Plains of New Zealand (NCERT, p. 29). Fig. 4.12 maps these six belts; it is read in the map-reading section below.

Commercial Agriculture II: Mixed, Dairy, Mediterranean and Market Gardening

Four more commercial systems complete the agricultural picture. Their core ideas, regions and exam-ready points sit in one table:

Mixed farming

Mixed farms are moderate in size and grow wheat, barley, oats, rye, maize, fodder and root crops. Fodder crops are an important component, and crop rotation and intercropping maintain soil fertility. Equal emphasis is laid on crop cultivation and animal husbandry — cattle, sheep, pigs and poultry provide the main income along with crops (NCERT, p. 29).

The system is characterised by high capital expenditure on farm machinery and buildings, extensive use of chemical fertilisers and green manures, and the skill and expertise of farmers. Fig. 4.14 maps its distribution in the developed world.

Dairy farming

Dairy farming is the most advanced and efficient type of milch-animal rearing. It is highly capital intensive — animal sheds, fodder storage, feeding and milching machines add to the cost — and highly labour intensive, because feeding and milching need rigorous care (NCERT, p. 29).

Unlike crop raising, there is no off season during the year. Dairying is practised mainly near urban and industrial centres, which provide a neighbourhood market for fresh milk and dairy products. The development of transportation, refrigeration, pasteurisation and other preservation processes has increased the duration for which dairy products can be stored (NCERT, p. 30).

Fig. 4.13, a dairy farm in Austria, shows the fixed investment — sheds and fodder storage — that makes dairy farming capital intensive before a single litre of milk is sold.

The three main commercial dairy regions are North-western Europe (the largest), Canada, and a third belt joining South-eastern Australia, New Zealand and Tasmania (NCERT, p. 30). Fig. 4.16 maps these belts.

Mediterranean agriculture

Mediterranean agriculture is highly specialised commercial agriculture, practised on either side of the Mediterranean sea in Europe and north Africa, from Tunisia to the Atlantic coast, and also in southern California, central Chile, the south-western parts of South Africa, and the south and south-western parts of Australia (NCERT, p. 31).

It is an important supplier of citrus fruits, and also produces olives and figs.

Viticulture (grape cultivation) is a speciality of the region — its high-quality grapes produce the best-quality wines, while inferior grapes are dried into raisins and currants. The region’s advantage is timing: more valuable crops such as fruits and vegetables are grown in winters, when there is great demand in European and North American markets (NCERT, p. 31).

Fig. 4.15(a) shows a vineyard in Switzerland and Fig. 4.15(b) shows grape collection on a collective farm in Kazakhstan — proof that grape cultivation extends beyond the Mediterranean basin itself.

Market gardening and horticulture

Market gardening and horticulture specialise in high-value crops — vegetables, fruits and flowers — grown solely for urban markets. Farms are small and located where good transport links exist with the urban centre where high-income consumers live. It is both labour and capital intensive, relying on irrigation, HYV seeds, fertilisers, insecticides, greenhouses and artificial heating in colder regions (NCERT, p. 31).

It is well developed in the densely populated industrial districts of north-west Europe, north-eastern USA and the Mediterranean regions. The Netherlands specialises in flowers and horticultural crops, especially tulips, which are flown to all major cities of Europe (NCERT, p. 31).

The two parts of Fig. 4.17 tell the location story of market gardening: (a) vegetables growing in the vicinity of the city, and (b) the produce being loaded into trucks and cycle carts for transport to city markets.

The farm sits near the market, and the transport is quick — in India, that can mean a cycle cart as much as a truck.

Truck farming and factory farming

Where farmers specialise in vegetables only, the activity is called truck farming. The name is a distance rule: the distance of a truck farm from the market is governed by the distance that a truck can cover overnight, so that vegetables reach the city market fresh (NCERT, p. 31).

Factory farming is a modern development in the industrial regions of Western Europe and North America. Poultry and cattle are reared in stalls and pens, fed on manufactured feedstuff, and carefully supervised against diseases. It demands heavy capital in buildings, machinery, veterinary services and heating and lighting, and its important features are breed selection and scientific breeding (NCERT, p. 32).

Co-operative and Collective Farming: Two Ownership Models

Types of farming can also be categorised by farming organisation — the way farmers own their farms and the government policies that help run them (NCERT, p. 31). The two ownership models are often confused, so keep them apart with this contrast:

Co-operative farming originated over a century ago and has been successful in many western European countries (NCERT, p. 32). Collective farming was introduced in the erstwhile Soviet Union to improve upon the inefficiency of previous methods and to boost agricultural production for self-sufficiency (NCERT, p. 32).

Mining: Profit Factors and Methods of Extraction

The history of mineral use in human development is reflected in the copper age, bronze age and iron age. In ancient times minerals were largely used for tools, utensils and weapons, but the actual development of mining began with the Industrial Revolution, and its importance has kept increasing (NCERT, p. 32).

Factors affecting mining activity

The profitability of mining depends on two main groups of factors (NCERT, p. 32):

• Physical factors: the size, grade and mode of occurrence of the deposits.
• Economic factors: the demand for the mineral, the technology available and used, the capital to develop infrastructure, and the labour and transport costs.

Methods of mining

Why is underground mining risky? Miners work inside the earth, so they face poisonous gases, fires, floods and caving — all of which cause fatal accidents. That is why ventilation and safety equipment are essential (NCERT, p. 33).

Fig. 4.18, an oil drilling operation in the Gulf of Mexico, shows mining under extreme conditions — the same capital and technology logic applies whether the mineral lies under a few metres of rock or under a sea.

Fig. 4.19 summarises the two methods in one diagram: open-cast mining works from the surface downwards for shallow deposits, while shaft mining sinks vertical shafts and radiating galleries to reach deep ores.

Finally, note the global shift: developed economies are retreating from the mining, processing and refining stages because of high labour costs, while developing countries with large labour forces and a drive for a higher standard of living are becoming more important.

Several countries of Africa, and a few of South America and Asia, earn over fifty per cent of their income from minerals alone (NCERT, p. 33).

Key Terms and Definitions You Must Know

Every definition the chapter expects you to recall, in order of appearance:

Quick Facts and Figures to Memorise (No Formulas Here)

This is a concept chapter, so there are no formulas to plug values into. Instead of a formula box, revise these pattern facts — they are the numbers and relationships that keep appearing in answers:

• People engaged in primary activities are red-collar workers, because of the outdoor nature of their work.
• Gathering is the oldest economic activity known.
• A shifting-cultivation plot is abandoned after 3 to 5 years, when the soil loses fertility.
• Intensive subsistence agriculture gives a high yield per unit area, but low per-labour productivity.
• Extensive commercial grain farming gives a low yield per acre, but high yield per person.
• Commercial dairy farming has three main belts: North-western Europe, Canada, and South-eastern Australia–New Zealand–Tasmania.
• Several African countries, and a few South American and Asian countries, earn over fifty per cent of their income from minerals alone.
• Gathering products cannot compete globally because synthetic substitutes are often better in quality and lower in price.
• Ownership of most plantations has passed to governments or nationals of the countries concerned.

Worked Example: Identify the Farming Type, Then Build a Differentiation Answer

Worked Example 1 — Identify the farming type from a description

Stimulus: A farm on the Canterbury Plains of New Zealand grows only wheat across thousands of hectares. Sowing and harvesting are done by combine crews, and the farm employs very few permanent workers.

1. Check the scale. “Thousands of hectares” means the farm is very large — this is a size marker.
2. Check the technology. Combine crews and few permanent workers mean full mechanisation — a technology marker.
3. Check the location. The Canterbury Plains of New Zealand appear in the chapter’s list of extensive commercial grain regions.
4. Conclude. This is extensive commercial grain cultivation, a commercial system of the semi-arid mid-latitudes.
5. Add the textbook markers. Wheat is the principal crop; the system gives a low yield per acre but a high yield per person, because one mechanised worker covers a vast area.

Final answer: The farm practises extensive commercial grain cultivation — large, mechanised, wheat-based and located in one of the six named mid-latitude grain belts.

Worked Example 2 — Skeleton for a 150-word differentiation answer

For a question that asks you to differentiate two systems, use this structure. It works for nomadic herding versus commercial livestock rearing and for any other pair in the chapter:

1. Opening line (one sentence): state the core difference in level — one is a primitive subsistence activity, the other is organised and capital intensive.
2. Body (about five points of contrast): compare movement (migrating with livestock vs rotating animals between fenced parcels), capital and technology, organisation of land (community territory vs permanent ranches), animals raised, and products and their destination (daily needs vs processed exports).
3. Conclusion (one line): both systems rear animals, but one is a way of life tied to pasture, while the other is a business tied to world markets.

The six-criteria comparison table in the pastoralism section supplies the exact content for every point in this skeleton — learn the table, and the 150-word answer writes itself.

Common Mistakes Students Make in Primary Activities

How to Approach the Textbook Exercises

Multiple-choice section (Exercise 1). Work by elimination — define each option, then match the question’s clause.

For example, floriculture is the term for growing flowers, so options describing other farm types drop out immediately; mixed farming is the system that deliberately mixes crops and animals, so it does not follow monoculture; and in the grain-region question, the Amazon Basin is the odd option because it appears nowhere in the chapter’s list of commercial grain belts.

30-word answers (Exercise 2). Keep a fixed shape: a one-line definition or position, one reason from the chapter, and one supporting point. The three prompts in your textbook — the future of shifting cultivation, market gardening near urban areas, and large-scale dairy farming as a result of transportation and refrigeration — all fit this shape.

Notice each is a ‘why’ or ‘evaluate’ prompt, so the reason, not the definition, is the heart of the answer.

150-word answers (Exercise 3). For a differentiation question, build a comparison table of about five criteria on the answer page, then close with a short conclusion. The chapter’s model question is nomadic herding versus commercial livestock rearing, and the six-criteria table on this page is exactly the material you would lay out.

For a ‘discuss the features’ question such as plantation agriculture, open with its defining features, name the plantation crops from the colonial examples table here, and end with today’s ownership picture.

Project/Activity. The chapter suggests a fieldwork option: visit a nearby village, observe the cultivation of some crops, ask the farmers, and list the various operations they perform. Use it as hands-on revision of the agricultural systems you have read about (NCERT, p. 35).

Map Reading: How to Use the Distribution Figures

All the distribution figures in this chapter are world maps with shaded belts. Use a two-step read: first, locate the latitude band of the shading; second, attach the region names the text lists for that belt. For every map, run three revision questions: where (latitude and environment), why (the environmental logic), and which local names (the regions).

Fig. 4.2 — Areas of subsistence gathering

Fig. 4.2 shows gathering as scattered pockets rather than one connected belt. The high-latitude pockets are northern Canada, northern Eurasia and southern Chile; the low-latitude pockets are the Amazon Basin, tropical Africa, the northern fringe of Australia and the interior parts of Southeast Asia. Read the pattern as: gathering survives where climate is harsh or forests kept settlement out.

Fig. 4.4 — Areas of nomadic herding

Fig. 4.4 shows three areas. The core region runs from the Atlantic shores of North Africa eastwards across the Arabian peninsula into Mongolia and Central China. The second region covers the tundra of Eurasia. Small southern-hemisphere patches appear in South-west Africa and on the island of Madagascar.

Fig. 4.6 — Areas of commercial livestock rearing

Fig. 4.6 concentrates in the New World and Australasia — the countries named in the text (New Zealand, Australia, Argentina, Uruguay and the USA) fall inside the shaded belts. Compare with Fig. 4.4: the old-world dry and cold belts belong to nomads, while the New World temperate grasslands belong to commercial ranches.

Fig. 4.7 — Areas of primitive subsistence agriculture

Fig. 4.7 shades the tropics — Africa, south and central America, and southeast Asia. Check yourself: why the tropics? Because forest dominates there, and slash-and-burn is the way tribal groups clear small patches for cultivation.

Fig. 4.8 — Areas of intensive subsistence farming

Fig. 4.8 shows one compact belt in the densely populated parts of monsoon Asia. Link the shading to the text’s logic: high population density makes holdings tiny and family labour the main input.

Fig. 4.12 — Areas of extensive commercial grain farming

Fig. 4.12 shows six named belts, all mid-latitude grasslands: the Eurasian steppes, the Canadian and American Prairies, the Pampas of Argentina, the Velds of South Africa, the Australian Downs and the Canterbury Plains of New Zealand. Notice the shading sits in the interiors of continents — matching the text’s phrase “interior parts of semi-arid lands of the mid-latitudes.”

Fig. 4.14 — Areas of mixed farming

Fig. 4.14 places mixed farming in the highly developed parts of the world: north-western Europe, eastern North America, parts of Eurasia and the temperate latitudes of the southern continents. The shading follows wealthy, industrialised regions rather than a single climate belt.

Fig. 4.16 — Areas of dairy farming

Fig. 4.16 shows the three dairy belts: North-western Europe (the largest), Canada, and the third belt joining South-eastern Australia, New Zealand and Tasmania. Read the belts next to major urban and industrial populations — that is the neighbourhood-market logic on a map.

Practice tip: trace each shaded belt on a blank world map and label it with the region names from the chapter. When a map question gives you a blank outline, the labelled belts are your answer.

FAQs: Primary Activities Class 12 Doubts

What is the difference between nomadic herding and commercial livestock rearing?

Nomadic herding is a primitive subsistence activity — herders depend on animals for food, clothing, shelter, tools and transport, and migrate with their livestock to pastures and water. Commercial livestock rearing is organised and capital intensive — permanent fenced ranches, a single type of animal, scientific breeding and health care, with products processed and exported.

The core difference is subsistence versus commercial organisation.

Why is shifting cultivation also called slash and burn agriculture?

Because the cultivator first cuts (slashes) the vegetation, then clears it by fire, and the ashes add to the fertility of the soil (NCERT, p. 27). The same system is called jhuming in north-eastern India, milpa in Central America and Mexico, and ladang in Indonesia and Malaysia.

What is transhumance and which Indian communities practise it?

Transhumance is the seasonal vertical migration from plains to mountain pastures in summers and back from high-altitude pastures to the plains in winters (NCERT, p. 24). In the Himalayas, the Gujjars, Bakarwals, Gaddis and Bhotiyas practise it.

What is truck farming and why is it called that?

Truck farming is market gardening that specialises in vegetables. It is called truck farming because the farm’s distance from the market is governed by the distance a truck can cover overnight, so the vegetables arrive in the city market fresh (NCERT, p. 31).

Why is dairy farming practised near urban and industrial centres?

Because towns and industrial areas are the neighbourhood market for fresh milk and dairy products (NCERT, p. 30). Fresh milk is perishable, so proximity matters; transportation, refrigeration, pasteurisation and other preservation processes have increased how long dairy products can be stored.

What are the two main factors that affect the profitability of mining?

Physical factors — the size, grade and mode of occurrence of the deposits — and economic factors — demand for the mineral, available technology, capital to develop infrastructure, and labour and transport costs (NCERT, p. 32).
