Primary Activities
Start here: why this chapter matters
Human activities that generate income are economic activities, grouped as primary, secondary, tertiary and quaternary. This chapter opens Unit III with the primary ones. Because they use land, water, vegetation and minerals directly, they are where the environment shapes human life most clearly — Chapter 1's human–nature relationship in its most practical form.
- Builds on Class 11: Koeppen's climates (Chapter 11) and natural vegetation (Chapter 14) explain where each farming type is found — Mediterranean agriculture in Cs climates, plantations in humid tropics, grain on mid-latitude grasslands.
- Builds on Chapters 1–3: possibilism (people adapting the land), population density (intensive farming of crowded Asia), and human development (plantations and cheap labour).
- Leads into Chapters 5–8: raw materials feed industry; products feed trade.
- Pairs with India: People and Economy (land resources and agriculture, mineral and energy resources).
- UPSC: GS1 (distribution of key natural resources, cropping patterns, factors of location of the primary sector), GS3 (agriculture), and many prelims questions on farming types and regions.

At a glance — the six ideas to carry away
- Primary activities depend directly on the environment; their workers are called red-collar workers (NCERT).
- Nomadic herding: three regions — N Africa–Arabia–Mongolia, Eurasian tundra, SW Africa and Madagascar; transhumance = plains in winter, mountain pastures in summer.
- Shifting cultivation = slash and burn: jhuming (NE India), milpa (Central America, Mexico), ladang (Indonesia, Malaysia).
- Intensive subsistence (monsoon Asia): high yield per area, low per worker; extensive grain: low per acre, high per person.
- Plantations: European colonists, large estates, single crop, cheap labour, export transport; mixed farming = crops + livestock.
- Co-operative farming most successful in Denmark; kolkhoz = Soviet collective; mining = open-cast or shaft.
1. Primary activities and hunting–gathering
Primary activities use the earth's resources — land, water, vegetation, building materials, minerals — and so depend directly on the environment. They include hunting and gathering, pastoral activities, fishing, forestry, agriculture, and mining and quarrying.
The earliest humans lived on animals they hunted and edible plants they gathered. People in very cold and very hot climates survived on hunting; coastal people still fish, though fishing has modernised. Early hunters used stones, twigs and arrows, so few animals were killed; illegal hunting (poaching) has since made many species extinct or endangered.
Gathering is practised in regions with harsh climates, often by primitive societies, for food, shelter and clothing. It needs little capital and very low technology; yield per person is very low and there is little or no surplus. It survives in high latitudes — northern Canada, northern Eurasia, southern Chile — and low latitudes — the Amazon Basin, tropical Africa, the northern fringe of Australia and interior South-east Asia.
Some gathering is now commercial: barks give quinine, tannin extract and cork; leaves give materials for beverages, drugs, cosmetics, fibres, thatch and fabrics; nuts give food and oils; tree trunks give rubber, balata, gums and resins. Still, gathering has little future globally: its products cannot compete in world markets, and synthetic substitutes are often better and cheaper.
- Opener photo: a huge flock of sheep packed beside a stream, watched by a single herder — pastoralism at a glance.
- Question box: why do coastal people fish and plains people farm, and what physical and social factors decide the primary activity of a region? (Answered in the in-text section.)
- Do You Know 1: people in primary activities are called red-collar workers because they work outdoors. (This is NCERT's usage; the label is not used consistently elsewhere, so learn it in NCERT's sense.)
- Fig. 4.1 — Women gathering oranges in Mizoram: two young women in traditional dress pick fruit from a laden tree, a basket on one's back — gathering as part of everyday life in north-east India.
- Do You Know 2: the part of chewing gum left after the flavour has gone is chicle, made from the milky juice of the zapota (sapodilla) tree.
- A world map with gathering areas shaded. The largest patches are the Amazon Basin and the Congo Basin of central Africa.
- Thin strips along the Arctic edge of Canada and Siberia and a strip in southern Chile make up the high-latitude zone.
- Smaller patches lie in interior South-east Asia and the large islands (Borneo, New Guinea) and on the northern fringe of Australia.
- Pattern to remember: the two extremes — dense equatorial forest and cold subpolar lands — where farming is hardest.
2. Pastoralism: nomadic herding and transhumance
Once people realised that hunting was unsustainable, they domesticated animals suited to their climate. Animal rearing today is either subsistence or commercial.
Nomadic herding (pastoral nomadism) is a primitive subsistence activity: herders rely on animals for food, clothing, shelter, tools and transport, and move with them according to the amount and quality of pasture and water. Each community has a traditionally recognised territory.
| Region | Main animals (NCERT) |
|---|---|
| Tropical Africa | Cattle |
| Sahara and Asiatic deserts | Sheep, goats, camels |
| Tibet and the Andes (mountains) | Yak, llamas |
| Arctic and sub-Arctic | Reindeer |
- Core region: from the Atlantic shores of North Africa eastwards across the Arabian peninsula into Mongolia and Central China.
- Second region: the tundra of Eurasia.
- Southern hemisphere: small areas in South-west Africa and on Madagascar.
Movement is either over vast horizontal distances or vertical, between elevations. Migration from plains to mountain pastures in summer and back to the plains in winter is transhumance. In the Himalaya, Gujjars, Bakarwals, Gaddis and Bhotiyas practise it; in the tundra, herders move north in summer and south in winter. Pastoral nomads are declining because of political boundaries and settlement plans by governments.
- Fig. 4.3: two herders drive a large flock of sheep up a road between pine-covered slopes ‘at the onset of summer’ — transhumance in action.
- Fig. 4.4 (map): one huge continuous belt from the Sahara through Arabia, Iran and Central Asia to Mongolia and the Tibetan plateau.
- Further shading: the Horn of Africa and the dry lands of East Africa; Namibia–Kalahari in south-west Africa; a small patch on Madagascar; and a long strip along the Arctic coast of Eurasia.
- The map shows almost no nomadic herding in the Americas or Australia — there, dry grasslands went to commercial ranching instead (compare Fig. 4.6).
- Transhumance is seasonal and vertical (plains ↔ mountains), with a fixed base — UPSC 1988's answer for ‘seasonal migration of men and animals from lower to higher altitudes in summer’.
- Tundra herders go north in summer, not south.
- The southern-hemisphere nomadic areas are in south-west Africa and Madagascar, not Australia or South America.
3. Commercial livestock rearing
Commercial livestock rearing is more organised and capital intensive. Ranching, associated with western cultures, is done on permanent ranches divided into fenced parcels; animals move from one parcel to the next as the grass is grazed, and their number is kept within the pasture's carrying capacity. Only one type of animal is reared — sheep, cattle, goats or horses. Meat, wool, hides and skins are processed, packed and exported. The emphasis is on breeding, genetic improvement, disease control and health care. Main countries: New Zealand, Australia, Argentina, Uruguay and the USA.
- Fig. 4.5 shows a herd of reindeer racing through a snowy corral with herders behind. Its caption says that in the northern regions of Alaska most of the ‘Eskimos’ own about two-thirds of the stock — commercial rearing in a land usually linked with nomadism. (In Alaska the peoples concerned are usually called Iñupiat and Yupik today — Beyond NCERT.)
- Fig. 4.6 (map): the western interior of the USA, the interior of eastern Brazil down to Argentina, Uruguay and Patagonia, the dry interior of southern Africa, most of Australia's interior, New Zealand, and the Kazakh steppe of Central Asia.
- Pattern: semi-arid grasslands in the ‘new’ lands settled by Europeans, plus the former Soviet steppe.
4. Subsistence agriculture: shifting and intensive
Agriculture takes many forms because physical and socio-economic conditions combine in many ways. In subsistence agriculture the farming area consumes all or nearly all of what it grows. It has two kinds: primitive and intensive.
Primitive subsistence agriculture (shifting cultivation) is practised by many tribes in the tropics — Africa, South and Central America and South-east Asia. Vegetation is cleared by fire, and the ashes add fertility: hence slash-and-burn agriculture. Patches are very small, tools are sticks and hoes. After 3 to 5 years the soil loses fertility and the farmer clears a new patch, perhaps returning later. A major problem: the cycle of jhum keeps getting shorter as parcels lose fertility. Local names: jhuming (north-eastern India), milpa (Central America and Mexico), ladang (Indonesia and Malaysia).
Intensive subsistence agriculture is found in the densely populated regions of monsoon Asia. Two types:
| (i) Dominated by wet paddy | (ii) Dominated by crops other than paddy | |
|---|---|---|
| Main crop | Rice | Wheat, soyabean, barley, sorghum; millets in dry India |
| Where (NCERT) | Wet monsoon lands | Northern China, Manchuria, North Korea, northern Japan; western Indo-Gangetic plains (wheat); dry western and southern India (millets) |
| Why | Abundant water, high density | Relief, climate and soil make paddy impractical |
| Features | Tiny holdings; family labour; little machinery; farmyard manure; high yield per area, low productivity per worker | Same, except that irrigation is often used |
- Fig. 4.7: the Amazon Basin and much of tropical South America, Central America and southern Mexico, a broad belt across tropical Africa from the west coast to East Africa, eastern Madagascar, and in Asia the hills of Myanmar and north-east India, mainland South-east Asia, Indonesia, the Philippines and New Guinea. Its legend says only ‘Subsistence agriculture’, though the caption says ‘primitive’.
- Fig. 4.8 uses two shades. Wet rice dominant (black): the Ganga–Brahmaputra plains and eastern and southern coasts of India, Bangladesh, Myanmar, Thailand, Vietnam, southern and eastern China, Java, the Philippines and southern Japan.
- Other crops dominant (grey): north and north-east China (Manchuria), the Korean peninsula, north-west India and Pakistan, and the drier Deccan.
- Nothing is shaded outside Asia: intensive subsistence farming is a monsoon-Asia system.
- Jhum is linked with tribal people of the north-eastern hills (UPSC 1979).
- Shifting cultivation is not eco-friendly in its shortened modern form; organic farming is (UPSC 1999).
- Intensive subsistence = high yield per hectare, low per worker — the reverse of extensive grain farming.
- ‘Slash and burn’ = primitive subsistence, not ‘extensive subsistence’ (exercise Q1-vii).
5. Plantation agriculture
Europeans who colonised many parts of the world introduced profit-oriented, large-scale plantations in their tropical colonies. Crops: tea, coffee, cocoa, rubber, cotton, oil palm, sugarcane, bananas, pineapples.
| Colonists | Plantations (NCERT) |
|---|---|
| French | Cocoa and coffee in West Africa |
| British | Tea in India and Sri Lanka; rubber in Malaysia; sugarcane and bananas in the West Indies |
| Spanish and Americans | Coconut and sugarcane in the Philippines |
| Dutch | Once a monopoly of sugarcane in Indonesia |
| Europeans (still today) | Some coffee fazendas in Brazil |
Today most plantations are owned by governments or nationals of the countries concerned.
- The two largest cocoa producers are Côte d'Ivoire and Ghana (UPSC 2024) — the West African cocoa belt that grew from colonial plantations.
- Africa does grow tea: Kenya is one of the world's largest tea exporters, so ‘there are no tea plantations in any African country’ is false (UPSC 2007).
- Rubber, a plantation crop of humid equatorial lands, comes mainly from South-east Asia — Thailand and Indonesia lead, followed by producers such as Vietnam, Côte d'Ivoire, India, China and Malaysia; its environmental costs include clearing of tropical forest and loss of biodiversity (UPSC Mains 2022).
6. Extensive commercial grain cultivation and mixed farming
Extensive commercial grain cultivation is practised in the interior of semi-arid mid-latitude lands. Wheat is the main crop, with corn, barley, oats and rye. Farms are very large, so everything from ploughing to harvesting is mechanised: low yield per acre, high yield per person. It 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.
- Fig. 4.11: three combine harvesters move through a wheat field, each emptying grain into a truck alongside; the caption says combine crews can harvest grain over many hectares in a single day.
- Fig. 4.12 (map): the Canadian Prairies and the US Great Plains, the steppe from Ukraine through southern Russia into Kazakhstan, the Pampas, a patch in the South African Veld, the wheat belts of south-west and south-east Australia, and New Zealand's Canterbury Plains.
- Every patch is a mid-latitude grassland — the natural vegetation link from Class 11.
Mixed farming is found in highly developed regions: north-western Europe, eastern North America, parts of Eurasia and the temperate southern continents. Farms are moderate in size; crops are wheat, barley, oats, rye, maize, fodder and root crops. Crop rotation and intercropping maintain fertility. Equal emphasis falls on crops and animals — cattle, sheep, pigs and poultry give the main income. It needs high capital for machinery and buildings, heavy use of chemical fertilisers and green manures, and skilled farmers.
- A broad belt across western and central Europe continuing as a band into Russia, and the US Midwest and East into south-eastern Canada.
- Small southern-hemisphere patches in south-eastern Brazil–Uruguay, south-east Africa and New Zealand, and patches in north-east China and Japan.
- Compare with Fig. 4.12: mixed farming lies on the wetter side of the grain belts.
- Mixed farming = crops + livestock together (UPSC 1984, 1986, 2012) — not two crops in one field (that is mixed cropping or intercropping).
- Mixed farming is not monoculture (exercise Q1-viii); plantation, grain and dairy farming are specialised.
- The Amazon Basin has no extensive grain farming (exercise Q1-v); the Pampas are in South America (UPSC 1980).
7. Dairy, Mediterranean agriculture and market gardening
Dairy farming is the most advanced and efficient rearing of milch animals. It is highly capital intensive (sheds, fodder storage, feeding and milking machines; breeding, health care, veterinary services) and highly labour intensive (rigorous feeding and milking, no off season). It lies near urban and industrial centres that buy fresh milk; transport, refrigeration, pasteurisation and other preservation have lengthened storage. Three regions: north-western Europe (largest), Canada, and south-eastern Australia, New Zealand and Tasmania.
- Fig. 4.13: black-and-white dairy cows in a long indoor shed in Austria, each in its own stall at a feeding rail — the capital-intensive, stall-fed system.
- Fig. 4.16 (map): in black, north-western Europe (Britain, the Low Countries, Denmark, southern Scandinavia and the Baltic), the Great Lakes–St Lawrence region of the USA and Canada, and south-eastern Australia, Tasmania and New Zealand.
- The map puts the North American belt across the north-eastern USA as well as Canada, while the text names only ‘Canada’ — learn it as north-eastern USA and south-eastern Canada.
Mediterranean agriculture is highly specialised commercial farming on both sides of the Mediterranean in Europe and in north Africa from Tunisia to the Atlantic coast, southern California, central Chile, south-western South Africa and south and south-western Australia. It supplies citrus fruits; viticulture is its speciality — the best wines from high-quality grapes, with inferior grapes dried into raisins and currants — and it also grows olives and figs. Its advantage: valuable fruits and vegetables grow in winter, when European and North American demand is high.
- (a): a vineyard in Switzerland — rows of vines on a slope running down to a lakeside town.
- (b): workers sorting crates of grapes on a collective farm in Kazakhstan — viticulture beyond the Mediterranean, and an example of collective farming (section 8).
Market gardening and horticulture grow high-value vegetables, fruits and flowers solely for urban markets. Farms are small, with good transport to cities with high-income buyers; farming is labour and capital intensive — irrigation, HYV seeds, fertilisers, insecticides, greenhouses, artificial heating in cold regions. It is developed in north-west Europe, the north-eastern USA and the Mediterranean; the Netherlands specialises in flowers, especially tulips, flown to European cities. Where farmers grow only vegetables it is truck farming — the distance from the market is what a truck can cover overnight. Factory farming in western Europe and North America rears poultry and cattle in stalls and pens on manufactured feed, with heavy capital for buildings, machinery, veterinary care, heating and lighting, and stress on breed selection and scientific breeding.
- (a): neat vegetable plots right on the edge of a city, with factory chimneys on the skyline.
- (b): sacks of vegetables loaded on to a truck and on to cycle carts for city markets. The scene looks Indian — market gardening for Indian cities, with small transport links of every size.
- Citrus fruit is the hallmark of Mediterranean agriculture (exercise Q1-vi).
- Growing flowers is floriculture (exercise Q1-iii); truck farming is vegetables only.
- Dairying is both capital intensive and labour intensive.
8. Farming by organisation: co-operative and collective
| Co-operative farming | Collective farming (kolkhoz) | |
|---|---|---|
| Basis | Farmers voluntarily pool resources in a society | Social ownership of the means of production and collective labour |
| Land | Individual farms remain intact | Land, livestock and labour pooled; only very small private plots kept for daily needs |
| What it does | Buys inputs, sells produce on the best terms, processes quality products cheaply | Meant to end the inefficiency of older methods and boost output for self-sufficiency |
| Where | Western Europe — Denmark, Netherlands, Belgium, Sweden, Italy; in Denmark practically every farmer is a member | The former Soviet Union |
- Soviet collectivisation was forced through from 1929 under Stalin; besides the kolkhoz (collective farm) there was the sovkhoz (state farm, with paid workers). The upheaval contributed to the famine of the early 1930s.
- Denmark's co-operative movement grew from the 1880s, especially in dairying. India's best-known example is the Anand (Amul) dairy co-operative model of Gujarat.
9. Mining
Human history is marked by minerals — the copper, bronze and iron ages. In ancient times minerals made tools, utensils and weapons; real development of mining began with the Industrial Revolution, and its importance keeps rising.
Surface (open-cast) mining is the easiest and cheapest way to mine minerals near the surface; overheads such as safety and equipment are low, and output is large and rapid. When ore lies deep, underground (shaft) mining is used: vertical shafts are sunk and galleries radiate to the ore; it needs lifts, drills, haulage vehicles and ventilation, and it is risky — poisonous gases, fires, floods and caving-in cause fatal accidents.
Developed economies are retreating from mining, processing and refining because of high labour costs, while developing countries with large labour forces are becoming more important. Several countries of Africa and a few of South America and Asia earn over 50 per cent of their earnings from minerals alone.
- Fig. 4.18: two oil-stained workers in hard hats wrestle a heavy pipe section on a rig floor, under the massive drilling gear — oil drilling in the Gulf of Mexico, showing the hard, risky labour of extraction.
- Fig. 4.19: a cross-section of rock layers. On the left, a shallow pit labelled open-cast or strip mining exposes a near-surface deposit.
- On the right, a vertical shaft topped by a winding tower beside a house drops through several layers, with side passages reaching the ore.
- The drawing shows the key difference: depth of the deposit decides the method.

What to remember
Numbers
One-liners
- Primary = directly from nature; red-collar workers (NCERT).
- Transhumance: plains in winter, mountain pastures in summer.
- Jhuming (NE India) · milpa (Central America) · ladang (Indonesia, Malaysia).
- Intensive subsistence: high yield per area, low per worker.
- Extensive grain: low yield per acre, high per person.
- Plantations: European colonists, single crop, cheap labour, export.
- Mixed farming = crops + livestock; not monoculture.
- Co-operative: farms stay individual; collective (kolkhoz): pooled.
Traps to avoid
- Mixed farming ≠ mixed cropping.
- Tundra herders go north in summer.
- Wheat is not a plantation crop.
- Plantations were developed by European colonists, not kolkhoz or viticulture.
- Citrus → Mediterranean agriculture; flowers → floriculture; vegetables only → truck farming.
- No extensive grain farming in the Amazon Basin.
- Dairying is both capital- and labour-intensive.
- The text names ‘Canada’ for the second dairy belt; the map shows NE USA too.
How to strategise
Prelims — what UPSC asks
- Definitions are the favourites: mixed farming asked three times (1984, 1986, 2012); transhumance (1988); jhum and tribal people (1979); classifying activities into sectors — dairy and mineral exploration are primary (2024).
- Regions: the Pampas (1980); plantation crops vs cash and horticulture crops (1992); tea in Africa (2007); cocoa's two leaders (2024). Learn each farming type with its regions from the maps.
- Sustainability angle: shifting cultivation is not eco-friendly in its modern, shortened form (1999).
Mains — where it appears and how to answer
- GS1: distribution of rubber-producing countries and their environmental issues (2022); non-farm primary activities and their link with India's physiography (2025).
- Answer frame for any ‘type of agriculture’ question: definition → physical conditions (climate, relief, soil) → economic features (capital, labour, technology, market) → regions with examples → problems and trends. Draw a world sketch map from your atlas or the idealised continent above.
- Link farming types to Koeppen climates (Class 11, Chapter 11) and to human development (plantation labour, nomads and borders) for higher-order answers.
