BharatNotes Why this chapter matters for UPSC: Primary activities — particularly agriculture — are central to both GS1 (world agriculture types, location factors) and GS3 (Indian agriculture, food security, crop patterns). GS1 Mains regularly asks about the geography of specific agricultural types (plantation, shifting cultivation, Mediterranean) and their environmental consequences. Mining geography connects to GS3 (mineral resources, environment) and GS2 (tribal rights, displacement). This chapter provides the global comparative framework that enriches Indian-context answers.
Contemporary hook: Shifting cultivation (jhum in northeast India) is caught between two imperatives: it is an ecologically sophisticated traditional system that allows forest regeneration, and it is increasingly seen as forest cover loss and a driver of carbon emissions. The debate about modernising shifting cultivation vs preserving it as traditional knowledge mirrors broader tensions between development and environmental justice.

PART 2 — Detailed Notes
Gathering and Hunting
Gathering and hunting represent the oldest form of human economic activity. Gatherers collect roots, berries, leaves, and nuts; hunters pursue animals. These activities are non-market, rely on local ecological knowledge, and leave minimal environmental footprint.
Modern remnants: Surviving gathering-hunting societies — Amazon tribes, Andaman Islanders, Inuit, !Kung San of Kalahari. These are often in protected status, and their land rights are legally contested.
UPSC link: India's Particularly Vulnerable Tribal Groups (PVTGs) — 75 groups notified, including Jarawas and Sentinelese of Andaman, Birhors of Jharkhand — still practice substantial gathering and some hunting. Protection of their land rights (Forest Rights Act 2006) is a recurring GS2 issue.
Pastoral Nomadism and Transhumance
Pastoral nomadism involves moving with livestock (camels, goats, sheep, cattle) in a seasonal circuit to find pasture and water. It is adapted to semi-arid and arid environments. Regions: Sahel zone (Africa), Central Asian steppes (Kazakhstan, Mongolia), Arabian Peninsula, Rajasthan-Gujarat (India).
Transhumance is the seasonal movement between mountain pastures (summer) and valley/plain pastures (winter). It is a response to altitudinal climate variation. Examples: Swiss Alps (cow to mountain pasture in summer); Himalayan transhumance (Gujjars and Bakarwals of J&K — move from Jammu winter grounds to Kashmir/Himalayan summer pastures).
💡 Explainer: Types of Subsistence Agriculture
Primitive/Shifting Cultivation: Known as jhum (NE India), milpa (Mexico), chena (Sri Lanka), ladang (Southeast Asia). Forest is cleared by burning, crops grown for 2–3 years, then left fallow for 10–20 years. Ecologically, this mimics natural forest disturbance cycles if the fallow period is long enough. Problem: as population grows, fallow periods shorten, soils exhaust, forest cover disappears.
Intensive Subsistence Wet Rice Cultivation: The dominant mode in monsoon Asia (India, China, Bangladesh, Japan, SE Asia). Flooded paddy fields support extraordinary population densities. Key features: bunds and irrigation, transplanting seedlings, double/triple cropping where water permits, enormous labour inputs.
Intensive Subsistence Dry Farming: In areas where water is insufficient for paddy, coarse cereals, wheat, and pulses are grown. The Chinese loess plateau, parts of the Deccan, semi-arid NW India are examples.
Commercial Agriculture Types
Commercial Grain Farming: Mechanised monoculture of wheat or corn for market. The "wheat belts" — Canadian Prairies, USA Great Plains, Argentinian Pampas, Australian Riverina — are large family farms or agribusiness operations.
Mixed Farming: Common in NW Europe (UK, Denmark, Germany) — combines crop cultivation (wheat, barley, root crops) with livestock raising (cattle, pigs). Provides stable income through diversification.
Dairy Farming: Highly intensive, market-oriented milk/butter/cheese production. Located near urban markets because milk is perishable. Denmark, Netherlands, Switzerland, New Zealand are major dairy exporters.
Mediterranean Agriculture: The classic "Garden of the World" — grapes (wine), olives (oil), citrus fruits, figs, wheat. The Mediterranean climate (hot dry summer, mild wet winter) is perfectly suited. Extends to California's Central Valley, Chilean central valley, and SW Australia.
Plantation Agriculture: Large, capital-intensive, single-crop estates growing cash crops for export. A legacy of colonial systems. Tea in India (Assam, Darjeeling — introduced by British), rubber in Malaysia (British), coffee in Brazil, sugar in Caribbean, cotton in American South (slave labour legacy).
🎯 UPSC Connect: Plantation Agriculture and Colonial History
Plantation agriculture's geography is literally a map of colonialism. Crops moved with colonial powers: tea from China to India (1840s East India Company); rubber from Amazon to SE Asia (British colonial transfer); sugarcane from New Guinea to Caribbean (Spanish/Portuguese/British plantations with African slave labour). Understanding this history contextualises current inequalities in agricultural land ownership, labour rights, and trade terms for these commodities.
Mining: Surface vs Underground
Open-cast / Surface mining: Earth above the ore body (overburden) is removed. Lower cost, safer, suitable for shallow deposits. Environmental impact: massive land disturbance, dust, chemical runoff.
Underground mining: Vertical shafts and horizontal tunnels. Higher cost, dangerous (cave-ins, gas explosions), but limited surface footprint. Used for deep deposits.
Environmental and Social Issues: Mining causes deforestation, groundwater contamination, displacement of tribal communities (Odisha bauxite mines, Jharkhand coal), air and water pollution. The "resource curse" — regions rich in minerals often have poor governance and low development outcomes (Niger Delta, Chotanagpur historically).
Fishing: Three Zones
Inshore fishing: Nearshore, small boats, artisanal. India's 4,000 km coastline hosts millions of small-scale fisherfolk.
Offshore fishing: Medium-distance, mechanised boats, trawlers. Depletes fish stocks if unregulated.
Deep Sea / Pelagic fishing: Long-distance factory ships. Japan, Norway, Russia, China are major deep-sea fishing nations. Concerns: overfishing of high-seas stocks, illegal, unreported, unregulated (IUU) fishing.
Aquaculture: Farming fish, shrimp, oysters in controlled water bodies. India is the 3rd largest aquaculture producer globally (FAO SOFIA 2024), after China and Indonesia. Concern: mangrove destruction for shrimp farms.
🔗 Beyond the Book: Blue Economy
"Blue Economy" refers to sustainable use of ocean resources for economic growth — fisheries, aquaculture, marine tourism, offshore wind, seabed mining, shipping. India's Blue Economy Policy (2023 draft) targets doubling the sector's contribution to GDP. The Indian Ocean region's fisheries, especially in EEZ waters, are economically vital but threatened by Chinese overfishing and climate change.

Exam Strategy
For Prelims: Know types of subsistence and commercial agriculture, their regions, and key crops. Know the difference between slash-and-burn names globally. Know top mining regions for coal, iron ore, bauxite.
For Mains GS1: Distinguish subsistence from commercial agriculture clearly. Use the locational factor framework. For plantation agriculture, bring in the colonial history — it differentiates answers. For mining, link to tribal displacement and Forest Rights Act.
For Mains GS3: India's agricultural types (kharif-rabi, Green Revolution areas, plantation belt) should be linked to this global framework. Blue Economy is a hot GS3 topic.
Map-based questions: Know where Mediterranean agriculture is practised (not just Mediterranean basin — also California, Chile, SW Australia, S. Africa's Cape region).
