Types of Farming
Master the classification of agricultural systems, from subsistence (shifting, nomadic, intensive) to commercial (plantation, mixed, extensive) and sustainable farming models.
1. Subsistence Farming Systems
Subsistence farming is categorized into primitive and intensive systems, depending on the level of technology and land availability.
Primitive Subsistence (Shifting Cultivation & Nomadic Herding): Characterized by small plots, use of primitive tools (hoe, dao, digging sticks), and reliance on monsoon/natural fertility. Also known as slash-and-burn or Jhuming in Northeast India.Intensive Subsistence: Found in densely populated regions of monsoon Asia. Farms are small, but high inputs of labor, manures, and irrigation are used to get maximum yield from the limited land. Double or triple cropping is common.
2. Commercial Farming Systems
Commercial farming uses modern inputs like HYV seeds, chemical fertilizers, and insecticides to achieve higher yields for sale in national or international markets.
Commercial Grain Cultivation: Practiced in temperate grasslands (Prairies, Steppes, Pampas). Farms are massive (hundreds of hectares), highly mechanized, and specialize in single grains like wheat or maize.Mixed Farming: Common in Europe and North America. Crops (wheat, barley, oats, fodder) are grown alongside animal husbandry. Crop rotation is strictly followed to maintain soil fertility.Plantation Agriculture: Introduced by Europeans in the tropics. Characterized by large estates, single-crop specialization, heavy capital investment, scientific methods, and processing facilities on or near the estate.
3. Shifting Cultivation: Regional & Global Nomenclature
Shifting cultivation is known by different local names globally and within India. It is a frequent area of questioning in competitive exams:
Region
Local Name
Northeast India (Assam, Meghalaya, Mizoram) Jhum / Jhuming
Madhya Pradesh Bewar, Dahiya, Mashan
Andhra Pradesh / Odisha Podu, Penda
Western Ghats (Kerala, Karnataka) Kumari
Mexico & Central America Milpa
Venezuela Conuco
Brazil Roca
Central Africa Masole
Malaysia & Indonesia Ladang
Vietnam Ray
4. Modern & Sustainable Farming Methods
To feed growing populations while preserving ecosystems, agriculture is adopting sustainable farming systems:
Organic Farming: Replaces chemical inputs with organic manures, bio-fertilizers, and natural pest control to maintain eco-health.Precision Agriculture: Uses technology (GPS, remote sensing, drones) to supply exact amounts of water, seeds, and nutrients, avoiding wastage.Dryland Farming: Adopted in regions with less than 75 cm annual rainfall. Focuses on moisture conservation and drought-resistant crops (millets, pulses).Vertical Farming & Hydroponics: Cultivating plants indoors in stacked layers, using nutrient-rich water solutions without soil. Highly space and water efficient.
Evolution of Farming Systems
10,000 BCE — Neolithic Revolution : Transition from hunting-gathering to settled primitive subsistence farming. Domestication of crops and animals begins.Pre-Colonial Era — Traditional Shifting Cultivation : Widespread practice of slash-and-burn agriculture (Jhuming) across forest communities globally, adapted to low population densities.17th-19th Century — Colonial Plantation Era : European colonizers introduce commercial plantation agriculture (tea, coffee, rubber, cotton) in tropical colonies for export markets.1960s-1970s — Green Revolution : Introduction of High-Yielding Varieties (HYV), synthetic fertilizers, and mechanical inputs, giving rise to intensive commercial and subsistence farming.2000s-Present — Precision & Sustainable Agriculture : Rise of organic farming, vertical hydroponics, and precision farming using IoT, GPS, and drones to optimize resource efficiency.
Key Questions & Answers
What is the primary objective of subsistence farming? To meet the consumption needs of the **farmer's family**, with little or no surplus left for sale in the market.
Which agricultural system is characterized by a single cash crop on a massive estate? **Plantation Agriculture**. Examples include tea in Assam, coffee in Brazil, and rubber in Malaysia.
What is Nomadic Herding (Pastoral Nomadism)? A primitive subsistence system where herders move from place to place with their animals for fodder and water along defined routes (e.g. Bhotiyas/Gujjars in Himalayas).
Why is Shifting Cultivation highly criticized in modern environmental science? Because it causes **deforestation**, loss of biodiversity, and severe **soil erosion** due to the continuous clearing of forest patches.
Memory Aids
Mnemonic 1: Shifting Cultivation Global Names : Remember the regional terms for slash-and-burn farming: 1. **Milpa** — Mexico & Central America 2. **Ladang** — Malaysia & Indonesia 3. **Roca** — Brazil 4. **Jhum** — Northeast IndiaMnemonic 2: Shifting Cultivation Indian Names : Local Indian names for shifting cultivation: • **Podu / Penda** — Andhra Pradesh • **Bewar / Dahiya / Mashan** — Madhya Pradesh • **Kumari** — Western Ghats (Kerala/Karnataka) • **Kuruwa** — JharkhandMnemonic 3: Mixed Farming vs Mixed Cropping : Never confuse mixed cropping (growing two crops together) with **Mixed Farming**. Mixed farming strictly means growing **crops** AND rearing **livestock** (cows, sheep, poultry) on the same agricultural holding.
Common Exam Traps
Trap 1: Confusing Mixed Farming with Mixed Cropping. Mixed farming is crop production + animal husbandry. Mixed cropping is simply growing two or more crops simultaneously on the same land.
Trap 2: Believing Extensive Commercial Grain Cultivation has high yield per hectare. In extensive farming, yield per hectare is **low** (due to huge farm sizes and less intensive input per unit area), but yield per worker is **very high**.
Trap 3: Assuming plantation crops are food crops for local subsistence. Plantation agriculture is entirely commercial, capital-intensive, export-oriented, and usually run as an industrial estate.
Trap 4: Thinking shifting cultivation is permanently settled. It is a migratory form of farming where the fields shift every 2-3 years, while the farmer's settlement may or may not move.
