SPECIALISED TYPOLOGIES
SUB-WORLD I — PURPOSE & OUTPUT DESTINATION
The Subsistence to Commercial Continuum (06.01 – 06.09)
MICRO-REALM 06.01
Primitive Subsistence
- Production entirely for family survival
- Slash-and-burn (Shifting cultivation)
- Zero capital, primitive tools
Intensive Subsistence (Rice)
- High population density regions
- Paddy-dominated monsoon Asia
- Maximum yield per hectare, low per capita
Intensive Subsistence (Non-Rice)
- Wheat, soybean, barley, sorghum
- Lower rainfall regions (North China, NW India)
- Heavy reliance on irrigation & manual labour
Semi-Commercial Transition
- Family consumption + Market surplus
- Cash crops introduced alongside food crops
- Increasing market integration
Commercial Grain Farming
- 100% production for market sale
- Highly mechanized, capital-intensive
- Prairies, Pampas, Steppes, Downs
Plantation Agriculture
- Large estates, single cash crop (Tea, Rubber)
- Colonial origins, export-oriented
- High capital + large wage-labour force
Agribusiness & Corporate
- Farming as a large-scale corporate enterprise
- Integration of production, processing, distribution
- Vertical integration monopolies
Contract Farming
- Agreement between farmer and buyer (MNC)
- Pre-agreed price, quality, and quantity
- Reduces price risk but limits farmer autonomy
Export-Oriented Agriculture
- Production specifically for foreign markets
- High-value crops (Flowers, Berries, Spices)
- Requires cold-chain logistics
SUB-WORLD II — FACTOR PROPORTIONS
Intensive vs Extensive Mechanics (06.10 – 06.18)
MICRO-REALM 06.10
Land-to-Labour Ratio
- The core determinant of intensity
- High labor/Low land = Intensive
- Low labor/High land = Extensive
Capital-Intensive Farming
- High financial input per hectare
- Machinery, fertilizers, advanced irrigation
- Maximizes yield per unit of labor
Labour-Intensive Farming
- High human input per hectare
- Common in densely populated developing nations
- Maximizes yield per unit of land
Extensive Pastoral Nomadism
- Vast land areas, very low capital/labor inputs
- Herding animals across arid/semi-arid regions
- Transhumance (seasonal migration)
Extensive Commercial Grain
- Huge farm sizes (thousands of hectares)
- Low yield per hectare, massive total output
- Highly mechanized, low labor requirement
HYV Intensification
- High-Yielding Varieties (Green Revolution)
- Biological & chemical intensification
- Requires assured irrigation & fertilizers
Precision Agriculture
- Tech-intensive, data-driven farming
- GPS, IoT sensors, drone mapping
- Micro-targeted inputs (water/fertilizer)
Controlled Environment (CEA)
- Greenhouses, polyhouses, net-houses
- Hyper-intensive spatial use
- Climate insulation & year-round production
Hydroponics & Vertical
- Soil-less farming (water nutrient solutions)
- 3D spatial intensification (stacked layers)
- Maximum yield per square meter of footprint
SUB-WORLD III — ENTERPRISE DIVERSITY
Mixed & Diversified Systems (06.19 – 06.27)
MICRO-REALM 06.19
Mixed Farming
- Cultivation of crops + Rearing of livestock
- Equal emphasis on both enterprises
- Symbiotic: Manure for crops, fodder for animals
Crop Diversification
- Growing a variety of crops on one farm
- Shift from regional dominance of one crop
- Reduces market & ecological vulnerability
Intercropping Systems
- Two or more crops grown simultaneously
- Distinct row arrangements (e.g., 2:1 ratio)
- Optimizes spatial & light resources
Crop Rotation Cycles
- Successive cultivation of different crops
- Same piece of land over seasons/years
- Maintains soil fertility (e.g., legume inclusion)
Agro-Pastoral Systems
- Integration of crops and pasture lands
- Livestock graze on crop stubble post-harvest
- Common in semi-arid transition zones
Silvi-Pastoral Integration
- Trees (silvi) + Pasture/Animals (pastoral)
- Trees provide shade and fodder (lopping)
- Prevents overgrazing degradation
Integrated Farming (IFS)
- Complex multi-enterprise systems
- Crops + Poultry + Fish + Apiary + Dairy
- Waste of one is input for another (Circular)
Polyculture vs Monoculture
- Monoculture: Single crop over vast areas (fragile)
- Polyculture: High biodiversity, mimicking nature
- Reduces pest outbreaks and nutrient depletion
Risk Buffering & Resilience
- Primary economic reason for diversification
- Protection against total crop failure (climate)
- Protection against price crashes (market)
SUB-WORLD IV — MARKET SPECIALISATION & TYPOLOGIES
Economic Focus & Agricultural Systems (06.28 – 06.36)
MICRO-REALM 06.28
Specialised Horticulture
- Market Gardening & Truck Farming
- High-value fruits and vegetables
- Peri-urban locations, daily urban demand
Viticulture
- Specialised cultivation of grapes
- Highly capital and labor intensive
- Strong link to wine production regions
Floriculture
- Commercial cultivation of flowers
- Highly specialized, tech-heavy (Greenhouses)
- Netherlands (Tulips) as a prime example
Commercial Dairy Farming
- Highly specialised animal husbandry
- Capital intensive (sheds, milking machines)
- Requires proximity to markets or strong cold-chains
Factory Farming (CAFOs)
- Concentrated Animal Feeding Operations
- Industrial-scale indoor livestock rearing
- Maximum efficiency, severe ethical/ecological concerns
Mediterranean Agriculture
- Highly specialised regional farming
- Adapted to dry summers / wet winters
- Olives, figs, citrus, viticulture
Organic Farming Systems
- Zero synthetic fertilizers or pesticides
- Relies on crop rotation, compost, biological pest control
- Premium market pricing (Certification)
Zero-Budget Natural Farming
0
- No external inputs (Zero credit/cost)
- Jivamrita (microbial culture from cow dung/urine)
- Acchadana (Mulching) & Waaphasa (Soil aeration)
Whittlesey’s Typology
- Derwent Whittlesey (1936)
- 13 major agricultural regions of the world
- Based on crop/livestock combo, intensity, disposal, structures
Core Ontological Distinctions
Intensive vs. Extensive FarmingIntensive farming applies high amounts of labor and/or capital to a small land area to maximize yield per hectare (e.g., Asian paddy fields, Dutch greenhouses). Extensive farming applies minimal labor/capital to vast tracts of land, resulting in low yield per hectare but high overall output (e.g., US wheat plains, nomadic herding).
Subsistence vs. CommercialSubsistence agriculture is driven by survival; the output is consumed directly by the farmer's family. Commercial agriculture is driven by profit; 100% of the output is sold into national or global markets.
Mixed vs. Diversified FarmingMixed farming specifically combines crop cultivation with livestock rearing as equal, symbiotic enterprises. Diversified farming means growing many different types of crops on the same farm to spread risk, but doesn't necessarily include animals.
