Mixed farming, dairy farming and Mediterranean agriculture

Detail

1. Mixed farming: what it is

• Mixed farming means growing crops and rearing livestock on the same farm. Both get equal importance.
• Crops grown: wheat, barley, oats, rye, maize, fodder crops and root crops (for example turnips and beet).
• Animals reared: cattle, sheep, pigs and poultry.

• Many of the crops become animal feed, and animal dung goes back to the fields. Each part supports the other.

• Farms are moderate in size. They are smaller than the huge wheat farms of the prairies or steppes, but much bigger than subsistence plots.

• Exam trap: mixed farming is not monoculture. Monoculture means growing a single crop on a field year after year, as on plantations or extensive wheat farms. Mixed farming spreads its output across many crops and animals.

2. Where mixed farming is found (Fig. 4.14)

It is found only in highly developed parts of the world:

• North-western Europe (UK, France, Germany, Benelux, Denmark)
• Eastern North America (north-eastern USA and south-eastern Canada, including the Corn Belt)
• Parts of Eurasia
• Temperate parts of the southern continents (for example the Argentine Pampas, South Africa and south-eastern Australia)

3. How mixed farming keeps soil fertile

• Crop rotation: different crops are grown one after another on the same field, season by season.
• Cereals use up nitrogen. Legumes and fodder crops put nitrogen back.
• Changing crops also breaks the life cycle of pests and diseases.

• The result is that soil fertility lasts without the field being left empty.

• Intercropping: two or more crops are grown together on the same field at the same time.

• Plants with deep roots and plants with shallow roots draw on different soil layers.

• The ground stays covered, so less soil is washed away.

• Chemical and green manures: green manure means growing a crop such as clover and ploughing it back into the soil to enrich it.

4. What mixed farming needs

• High capital spending on farm machinery, buildings (barns, sheds, silos), and chemical and green manures.
• Skilled and well-trained farmers who can run crop and animal work together.
• Good access to city markets through roads and railways.

5. Beyond NCERT: the US Corn Belt

• Location: the Corn Belt is a large, fertile area on the north-central plains of the USA. It runs from western Ohio to eastern Nebraska [4]. Its core states are Iowa, Illinois, Indiana and Nebraska.
• Why it suits farming:
• Deep, dark prairie soils (mollisols, rich in humus)
• Hot, wet summers

• Flat land that machines can work easily

• What it grows and why:

• Maize and soybeans are grown mainly to feed hogs (pigs) and cattle. This makes it a classic crop-plus-livestock (mixed) system.
• Iowa's main farm products are corn (maize), soybeans, hogs and cattle, and Iowa usually ranks first in US corn output [4].

• Nearly 80% of the USA's corn and soybeans come from the Midwestern Corn Belt [5].

• World position: the USA is the world's largest maize producer, with more than 40% of world corn output. China, the European Union and Brazil come next [6].

6. Dairy farming: what it is

• Dairy farming is the most advanced and efficient way of rearing milch animals (animals kept for their milk).
• It is highly capital intensive. Farmers must pay for:
• Animal sheds
• Storage for fodder (silage pits, silos)

• Feeding and milking machines

• It is highly labour intensive.

• Cows must be fed and milked twice a day, every day.

• So there is no off-season, unlike crop farming.

• There is strong stress on animal breeding (high-yield breeds such as Holstein-Friesian and Jersey), health care and veterinary services.

7. Why dairies sit near cities

• The chain from cause to result:
• Fresh milk spoils quickly.
• So dairies grew up close to urban and industrial centres, where people buy milk and milk products every day.
• Better transport, refrigeration and pasteurisation (heating milk to kill germs, then cooling it fast) now keep dairy products fresh much longer. This has stretched the distance between farm and market.

8. Dairy regions of the world (Fig. 4.16)

Rank / region	Area covered	Main advantage
1. North-western Europe (largest)	Denmark, Netherlands, UK, France, Germany, Switzerland	Cool, moist climate, rich grass and large city markets
2. Canada	South-east, Great Lakes and St Lawrence area	Markets in nearby cities and in the USA
3. South-eastern Australia, New Zealand and Tasmania	Victoria and New South Wales, New Zealand, Tasmania	Rain all year and grass for grazing all year; dairy goods are exported

9. Beyond NCERT: India's co-operative dairy model

• India ranks 1st in the world in milk production. It produces about 25% of world milk [2][3].
• Output was 247.87 million tonnes in 2024-25, up 3.58% on 2023-24 [2][3].
• Output grew at a CAGR of 5.41% (CAGR: compound annual growth rate, the average yearly growth rate) from 146.31 million tonnes in 2014-15 to 247.87 million tonnes in 2024-25 [3].
• Per capita milk availability in 2024-25 was 485 grams per day. The world average was 328 grams per day in 2024 [3].
• Operation Flood (1970) set up Anand-pattern co-operatives in milk-producing districts. Milk collected by these co-operatives was sent to cities. This made India the world's largest milk producer [3].
• Milk output was 21.2 million tonnes in 1968-69, before Operation Flood [3].
• It rose to 30.4 million tonnes in 1979-80 and 51.4 million tonnes in 1989-90 [3].
• Anand pattern: a three-tier set-up of village society, district union and state federation, as in Amul of Anand, Gujarat.

Feature	Western dairying (NW Europe, NZ)	Indian dairying
Farm unit	Large, mechanised farm	Smallholder with 1-5 animals
Capital	Very high (machines, sheds)	Low per farmer; co-operative pools the money
Animals	Mostly exotic high-yield cows	Cows and buffaloes, many indigenous breeds
Organisation	Private, commercial	Village co-operatives (Anand pattern)

10. Mediterranean agriculture: where and why

• Mediterranean agriculture is highly specialised commercial farming. It is practised wherever the Mediterranean climate is found. In the Köppen system this climate is Csa/Csb:
• C means a mild climate.
• s means a dry summer.

• a means a hot summer, and b means a warm summer.

• What causes the climate:

• In summer the subtropical high-pressure belt moves towards the pole and sits over these areas. This gives dry, sunny summers.
• In winter the belts move towards the equator, and the westerlies bring rain from cyclones.
• The result is a mild, rainy winter and a dry summer, found mostly on the western sides of continents at about 30°-45° latitude.

Region	Continent / location
Both sides of the Mediterranean Sea: southern Europe, and North Africa from Tunisia to the Atlantic coast	Europe and Africa
Southern California	North America (west coast)
Central Chile	South America (west coast)
South-western South Africa (Cape region)	Africa
South and south-western Australia (around Perth and Adelaide)	Australia

11. Mediterranean crops

• Citrus fruits (oranges, lemons) are an important supply. In Spain, Sicily and Cyprus, citrus depends on irrigation, because summers are dry [7].
• Viticulture (growing grapes) is the speciality of the region.
• High-quality grapes make the world's best wines.
• Poorer grapes are dried into raisins and currants.

• In Europe, vines grow widely south of about latitude 50° N. Italy, France and Germany are especially important [7].

• Olives and figs are other main crops.

• Olive trees are found only in Mediterranean-climate regions. They are often planted on sloping, broken and terraced land [7].

• Their deep roots and thick, waxy leaves help them survive the dry summer.

• The winter advantage:

• Winters are mild, so valuable fruits and vegetables can be grown in winter.
• This is when demand in Europe and North America is highest, because farms there are frozen or idle.
• So the region earns high prices from exporting these winter crops.

Prelims Hooks

• Mixed farming gives equal weight to crops and livestock. It is not monoculture, which is a common "which is NOT a feature" trap.
• Crop rotation means different crops one after another on the same field. Intercropping means two or more crops on the same field at the same time.
• Corn Belt core states: Iowa, Illinois, Indiana and Nebraska. The belt runs from western Ohio to eastern Nebraska. Iowa leads the USA in corn. The maize mostly feeds hogs and cattle.
• The USA is the largest maize producer, with more than 40% of world output [6].
• Dairy farming is both capital intensive and labour intensive, with no off-season. Its largest region is north-western Europe. The other regions are Canada and SE Australia, New Zealand and Tasmania.
• India ranks 1st in milk: 247.87 million tonnes in 2024-25, about 25% of world output [2][3]. Operation Flood began in 1970 and was built on Anand-pattern co-operatives (Amul).
• Mediterranean climate = Köppen Csa/Csb: dry summer and rainy winter, on the western side of continents at about 30°-45° latitude.
• Match each Mediterranean region with its country: Central Chile, southern California (USA), SW South Africa (Cape), S and SW Australia, and North Africa from Tunisia to the Atlantic.
• Viticulture is the speciality of Mediterranean agriculture. Poorer grapes become raisins and currants.
• Mediterranean farmers make money by selling fruit and vegetables in winter, when demand in Europe and North America is at its peak.

Mains Points

• Why commercial farming types are found where they are:
• Mixed farming and dairying need capital, skill, markets and transport. That is why they are concentrated in developed temperate regions (NW Europe, eastern North America).

• Mediterranean agriculture follows a climate (Csa/Csb), not a level of development. This is why it is found on five continents.

• Mixed farming is a sustainable model: crop rotation, intercropping, green manure and recycling of dung keep the soil fertile. This holds lessons for India's soil-health and crop-diversification efforts, for example moving away from rice-wheat monoculture in Punjab and Haryana.

• Two models of dairying: the Western model uses large, mechanised, capital-heavy farms. India's model is smallholder and co-operative (Operation Flood, Anand pattern). It took output from 21.2 million tonnes in 1968-69 to 247.87 million tonnes in 2024-25 [2][3]. It spreads income to the countryside, but milk yield per animal is still low (GS-I and GS-III).
• Climate risk to Mediterranean agriculture: the region depends on a dry summer and winter rain, and citrus needs irrigation [7]. This makes it exposed to drought and heatwaves (for example in California, Spain and Chile). Water management is the key policy concern.
