Chapter 4: Primary Activities

Introduction

Economic activities are grouped as primary, secondary, tertiary and quaternary. Primary activities depend directly on the environment. They use the earth's land, water, vegetation, building materials and minerals, and include hunting and gathering, pastoral activities, fishing, forestry, agriculture, and mining and quarrying. People in primary activities are called red-collar workers because their work is outdoors.

Key Concepts

1. Hunting and Gathering

These are the oldest economic activities.

  • Gathering happens in harsh climates. It needs little capital, uses very low technology, and gives low yield per person with little or no surplus.
  • 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 of South-east Asia.
  • Chicle, the base of chewing gum, comes from the milky juice of the zapota tree.
  • Gathering has little chance of becoming important globally, because synthetic products have replaced many gathered items.

    • 2. Pastoralism

    Nomadic herding (pastoral nomadism) is a primitive subsistence activity. Herders rely on animals for food, clothing, shelter, tools and transport. They move with pastures and water, each within a traditional territory.

  • 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: South-west Africa and Madagascar.
  • Transhumance is seasonal movement between plains and mountain pastures. In the Himalaya, the Gujjars, Bakarwals, Gaddis and Bhotiyas move up in summer and down in winter. Tundra herders move south to north in summer.
  • Nomads are declining because of political boundaries and new settlement plans.

    • Commercial livestock rearing is organised, capital intensive and associated with western cultures.

  • It uses permanent ranches divided into fenced parcels, stocked according to carrying capacity.
  • One type of animal is reared: sheep, cattle, goats or horses.
  • The emphasis is on breeding, genetic improvement and disease control.
  • Main countries: New Zealand, Australia, Argentina, Uruguay and the USA.

    • 3. Agriculture

    (a) Primitive subsistence agriculture (shifting cultivation)

  • It is practised in the tropics of Africa, South and Central America and South-east Asia.
  • Land is cleared by fire, so it is also called slash and burn.
  • Patches are small and tools are primitive (sticks and hoes).
  • After 3 to 5 years fertility falls and the farmer shifts. The jhum cycle keeps getting shorter.
  • Names: Jhuming in north-eastern India, Milpa in Central America and Mexico, Ladang in Indonesia and Malaysia.

    • (b) Intensive subsistence agriculture (monsoon Asia)

  • (i) Wet paddy dominated: tiny holdings, family labour, farmyard manure, high yield per unit area but low labour productivity.
  • (ii) Other crops dominated: wheat, soyabean, barley and sorghum in northern China, Manchuria, North Korea and North Japan; wheat in the western Indo-Gangetic plains; millets in dry western and southern India. Irrigation is often used.

    • (c) Plantation agriculture was introduced by Europeans in tropical colonies.

  • Features: large estates, large capital, managerial and technical support, scientific methods, single-crop specialisation, cheap labour and good transport.
  • 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 held a monopoly on sugarcane in Indonesia.
  • Brazil: coffee fazendas.

    • (d) Extensive commercial grain cultivation

  • It is found in semi-arid mid-latitude interiors, with wheat as the main crop.
  • Farms are huge and fully mechanised: low yield per acre but high yield per person.
  • Regions: Eurasian steppes, Canadian and American Prairies, Pampas of Argentina, Velds of South Africa, Australian Downs and the Canterbury Plains of New Zealand.

    • (e) Mixed farming

  • It is found in north-western Europe, eastern North America, parts of Eurasia and the temperate southern continents.
  • Crops and animals get equal emphasis, and capital expenditure is high.

    • (f) Dairy farming

  • It is the most advanced rearing of milch animals.
  • It is capital and labour intensive, has no off season, and is located near urban markets.
  • Three regions: north-western Europe (largest), Canada, and south-eastern Australia with New Zealand and Tasmania.

    • (g) Mediterranean agriculture

  • It is found on both sides of the Mediterranean, in North Africa from Tunisia to the Atlantic, southern California, central Chile, south-western South Africa and south-western Australia.
  • It produces citrus fruits and specialises in viticulture; inferior grapes become raisins and currants. Olives and figs are also grown.
  • Winter fruit and vegetables supply European and North American markets.

    • (h) Market gardening and horticulture

  • High-value vegetables, fruits and flowers are grown for urban markets.
  • The Netherlands grows tulips.
  • Vegetable-only farming is called truck farming, because the distance is set by how far a truck can go overnight.
  • Factory farming raises poultry and cattle in stalls on manufactured feed.

    • (i) Farming organisation

  • Collective farming (Kolkhoz): social ownership in the former Soviet Union, with small private plots allowed.
  • Co-operative farming: voluntary pooling. It is most successful in Denmark, where practically every farmer is a member.

    • 4. Mining

  • Physical factors: size, grade and mode of occurrence of the deposit.
  • Economic factors: demand, technology, capital, and labour and transport costs.
  • Open-cast (surface) mining is the easiest and cheapest, with large and rapid output.
  • Shaft (underground) mining uses vertical shafts and galleries. It is risky because of poisonous gases, fires, floods and caving in.
  • Developed economies are retreating from mining. Several African countries earn over 50% of their income from minerals.

    • Map Work

    Mark the following on a world map:

  • The nomadic herding regions.
  • The extensive grain regions: steppes, prairies, pampas, velds, Downs and Canterbury.
  • The three dairy regions.
  • The Mediterranean agriculture areas.
  • The places named for shifting cultivation (north-east India, Mexico, Indonesia and Malaysia).

    • Key-Facts Sheet

  • Primary workers are red-collar workers.
  • Shifting cultivation lasts a 3–5 year cycle.
  • Co-operative farming is most successful in Denmark.
  • Kolkhoz belongs to the former Soviet Union.
  • Chicle comes from zapota.
  • The largest dairy region is north-western Europe.
  • The truck-farming distance is one night's truck journey.

    • Board Exam Focus

    MCQs in the exercises:

  • Wheat is not a plantation crop.
  • Co-operative farming is most successful in Denmark.
  • Growing flowers is called floriculture.
  • Plantation agriculture was developed by European colonists.
  • There is no extensive grain farming in the Amazon Basin.
  • Citrus belongs to Mediterranean agriculture.
  • Slash and burn is primitive subsistence agriculture.
  • Mixed farming does not follow monoculture.

    • Outline: Nomadic herding versus commercial livestock rearing (150 words).

  • Compare subsistence with commercial.
  • Compare movement with permanent ranches.
  • Compare many animal types with one type.
  • Compare traditional territory with fenced parcels by carrying capacity.
  • Compare regions: North Africa to Mongolia versus NZ, Australia, Argentina, Uruguay and the USA.

    • Outline: Features of plantation agriculture.

  • List the seven features.
  • Name the European powers and their crops.

    • Outline: The future of shifting cultivation is bleak (30 words).

  • The jhum cycle is shrinking and fertility is lost.
  • Primitive tools give a poor yield.

    • Key Terms

  • Primary activity (प्राथमिक क्रियाकलाप): an activity directly dependent on the environment.
  • Red-collar workers (लाल कॉलर श्रमिक): outdoor primary workers.
  • Pastoral nomadism (चलवासी पशुचारण): herding while moving.
  • Transhumance (ऋतु-प्रवास): seasonal vertical migration.
  • Shifting cultivation (स्थानांतरी कृषि): slash and burn.
  • Plantation agriculture (रोपण कृषि): European-introduced estates.
  • Mixed farming (मिश्रित कृषि): crops with livestock.
  • Viticulture (अंगूर की खेती): grape cultivation.
  • Truck farming (ट्रक कृषि): vegetables for urban markets.
  • Co-operative farming (सहकारी कृषि): voluntary pooling of resources.
  • Collective farming (सामूहिक कृषि): Kolkhoz.
  • Open-cast mining (विवृत खनन): surface mining.
  • Shaft mining (कूपकी खनन): underground mining.

    • Common Mistakes

  • Calling transhumance "nomadic herding". Transhumance is seasonal movement between plains and mountains.
  • Saying extensive grain farming has high yield per acre. It is low per acre and high per person.
  • Treating mixed farming as monoculture. It combines crops and animals.
  • Naming Russia or the Netherlands for co-operative success. The textbook answer is Denmark.
  • Writing that shaft mining is cheaper. Open-cast mining is the cheapest and easiest.

    • 💡 Key Learning Points

    • ✓Define primary activities and red-collar workers, and describe hunting and gathering zones.
    • ✓Contrast nomadic herding and transhumance with commercial livestock rearing.
    • ✓Classify the agricultural systems from primitive subsistence to market gardening with their regions.
    • ✓Identify the features and European origins of plantation agriculture.
    • ✓Explain the factors affecting mining and compare open-cast and shaft mining.

    👨‍🏫 Teaching Tips

    • →Use an outline world map as a running wall chart: shade each farming type as you teach it.
    • →Ask students to connect the local names for shifting cultivation (jhuming, milpa, ladang) to their countries in a matching drill.
    • →Pose the textbook puzzle 'low yield per acre but high yield per person' and let students reason it out from farm size and mechanisation.
    • →Compare nomadic herding and ranching with a two-column comparison on the board (movement, capital, animals, regions).
    • →Show a chewing gum wrapper and reveal chicle from the zapota tree to make gathering memorable.
    • →Link transhumance to Indian communities (Gujjars, Bakarwals, Gaddis, Bhotiyas) and ask students where they have seen herders move.
    • →Before tests, drill all eight textbook MCQs, since boards reuse them often.
