A combine harvester sweeping through the Canadian Prairies can clear hundreds of hectares of wheat in a single day. A Dutch dairy farmer milks cows by machine twice a day, all year, with no off-season. A Californian orchardist dries grapes into raisins for the European market. These are the high-capital, high-output systems of commercial agriculture — and this part of Chapter 4 walks you through five of them: extensive grain cultivation, mixed farming, dairy farming, Mediterranean agriculture, and market gardening.
Extensive commercial grain cultivation? is practised in the interior parts of the semi-arid mid-latitudes. Wheat is the principal crop, though corn, barley, oats and rye are also grown. The size of the farm is very large — therefore the entire chain of operations from ploughing to harvesting is mechanised. There is low yield per acre but high yield per person.
Figure 4.6: Extensive commercial grain farming 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.
Figure 4.7: Approximate share of world wheat production by major belt. Most wheat actually comes from intensive Asian belts (China, India), but in terms of the extensive commercial model the Prairies, Pampas and Steppes lead.
Mixed farming? is found 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 defining feature is that equal emphasis is laid on crop cultivation and animal husbandry; one income stream feeds the other.
Mixed farms are moderate in size. The crops associated with mixed farming are wheat, barley, oats, rye, maize, fodder and root crops. Fodder crops are an important component of the system, since they feed the livestock that simultaneously fertilise the soil. Crop rotation and intercropping play an important role in maintaining soil fertility.
Animals like cattle, sheep, pigs and poultry provide the main farm income alongside crops. Mixed farming is characterised by high capital expenditure on farm machinery and farm buildings, extensive use of chemical fertilisers and green manures, and the skill and expertise of the farmers themselves.
| Region | Example Countries / Areas | Why Suitable |
|---|---|---|
| North-western Europe | UK, Ireland, France, Belgium, Netherlands, Germany, Denmark | Cool temperate climate, fertile soils, dense urban markets, long farming tradition |
| Eastern North America | Eastern USA & Eastern Canada (corn-belt fringe) | Diversified climate, urban demand, transport networks |
| Parts of Eurasia | Western Russia, Belarus, parts of Ukraine | Forest-steppe transition, mixed soils |
| Temperate Southern continents | Parts of South Africa, Australasia (Australia & New Zealand) | Mid-latitude temperate climate, European settler heritage of mixed practice |
NCERT highlights that mixed farming gives equal emphasis to crops and livestock. Examine why this balance is economically and ecologically clever, drawing on at least two arguments from each side.
Dairy farming? is the most advanced and efficient type of rearing of milch animals. It is highly capital-intensive. Animal sheds, storage facilities for fodder, feeding and milking machines all add to the cost of running a dairy. Special emphasis is laid on cattle breeding, health care and veterinary services.
Dairy is also highly labour-intensive, because feeding and milking demand rigorous, daily care. Unlike crop farming, there is no off-season during the year — cows must be milked every day of the calendar.
Dairy farming is practised mainly near urban and industrial centres, which provide a neighbourhood market for fresh milk and dairy products. The development of three technologies has steadily extended the supply chain:
Figure 4.8: The three major dairy belts: (1) NW Europe — the largest, (2) Canada and the bordering NE United States, and (3) South-eastern Australia, New Zealand and Tasmania.
Mediterranean agriculture? is a highly specialised commercial agriculture, practised in countries on either side of the Mediterranean Sea — in Europe (Italy, Spain, Greece, southern France) and in north Africa from Tunisia to the Atlantic coast — as well as in lookalike climatic regions elsewhere: southern California, central Chile, the south-western parts of South Africa, and the south and south-western parts of Australia.
This region is an important supplier of citrus fruits — oranges, lemons, mandarins. Viticulture, or grape cultivation, is a special speciality of the Mediterranean region. The world's best-quality wines, with distinctive flavours, are produced from high-quality grapes here. The inferior grapes are dried into raisins and currants. The region also produces olives and figs.
Market gardening? and horticulture specialise in the cultivation of high-value crops — vegetables, fruits and flowers — solely for the urban markets. Farms are small and located where there are good transportation links with the urban centre, and where high-income consumers live. The activity is both labour and capital intensive, and lays emphasis on the use of irrigation, HYV seeds, fertilisers, insecticides, greenhouses and artificial heating in colder regions.
This type of agriculture is well developed in the densely populated industrial districts of north-west Europe, north-eastern United States of America and the Mediterranean regions. The Netherlands specialises in growing flowers and horticultural crops — especially tulips, which are flown to all major cities of Europe.
Where farmers specialise in vegetables only, the activity is called truck farming?. The distance of truck farms from the market is governed by the distance that a truck can cover overnight — hence the name. The farmer must reach the city wholesaler before the morning auction; if the produce is not at the market by sunrise, it cannot fetch a fair price.
Alongside market gardening, a modern development in the industrial regions of Western Europe and North America is factory farming?. Livestock — particularly poultry and cattle — are reared in stalls and pens, fed on manufactured feedstuff, and carefully supervised against diseases.
This requires heavy capital investment in buildings, machinery for various operations, veterinary services, heating and lighting. One of the important features of poultry farming and cattle rearing is breed selection and scientific breeding. Adjacent to factory farming is the rise of organic agriculture and community-supported agriculture (CSA) — small-scale, ecologically managed farms that supply boxes of seasonal produce directly to subscribing urban households.
| System | Principal output | Capital | Labour | Yield character |
|---|---|---|---|---|
| Extensive Grain | Wheat, corn, barley, oats, rye | High (machines) | Very low | Low/acre, high/person |
| Mixed Farming | Wheat & livestock — equal emphasis | High | Moderate | Diversified income |
| Dairy Farming | Milk & dairy products | Very high | Very high | No off-season |
| Mediterranean | Citrus, grapes, olives, figs | High | Moderate-High | High off-season prices |
| Market Gardening | Vegetables, fruits, flowers | Very high | Very high | High value/area |
NCERT instructs you to locate 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 on the world map. On a blank world map, mark each of these belts with a yellow shade and label the principal grain.
NCERT asks: Why does extensive commercial grain farming have low yield per acre but high yield per person? Build a four-step explanation, and add one consequence for the world wheat market.
NCERT highlights that the development of transportation, refrigeration, pasteurisation and other preservation processes have increased the duration of storage of dairy products. Critically evaluate how a small Anand-style cooperative would have fared without these technologies, and what each technology specifically enabled.
Large-scale, highly mechanised farming of wheat (also maize, barley, oats, rye) on big farms in mid-latitude grasslands. Yield per acre is low but yield per labourer is high. Examples: Prairies of Canada, Steppes of Russia, Pampas of Argentina.
Mixed farming combines crop cultivation and animal husbandry on the same farm, found in highly developed regions like North-Western Europe, USA and New Zealand — wheat, oats, fodder along with cattle, pigs and poultry.
Dairy farming is the most advanced rearing of milch animals for milk products — capital and labour intensive, near urban centres. Three belts: North-Western Europe, North-Eastern USA-Canada, and South-Eastern Australia.
Highly specialised commercial farming around the Mediterranean Sea, in Central California, central Chile, south-west South Africa and south-west Australia. Citrus fruits, olives and grapes (viticulture) are key crops; floriculture is also important.
Market gardening (horticulture) and truck farming grow high-value vegetables, fruits and flowers for urban markets. Truck farming is named after overnight trucks — the distance a truck travels in a night is the truck-farming radius.
Large-scale livestock rearing in stalls and pens with scientifically formulated food and disease protection. Animals are reared in industrial conditions for mass production of meat, eggs and dairy.
Viticulture is the cultivation of grapes, mostly for wine. Hot dry Mediterranean summers are ideal — France, Italy and Spain are leading wine producers and viticulture is a Mediterranean speciality.
