📖 PART 1: Introduction to Economic Activities
The transformation from a plant to a finished product involves three types of economic activities: Primary, Secondary, and Tertiary.
- Primary Activities: Involve extraction and production of natural resources (Agriculture, fishing, gathering).
- Secondary Activities: Involve the processing of these resources (Manufacturing steel, baking bread, weaving cloth).
- Tertiary Activities: Provide support to primary and secondary sectors through services (Transport, trade, banking, insurance, advertising).
Favourable topography of soil and climate are vital. The land on which crops are grown is known as arable land.
🚜 PART 2: Types of Farming

Right side: A massive American wheat farm with a huge green combine harvester machine covering acres of land.
Farming can be classified into two main types depending upon geographical conditions, demand of produce, labour, and level of technology:
1. Subsistence Farming
This type of farming is practised to meet the needs of the farmer's family. It uses low levels of technology and household labour.
- Intensive subsistence agriculture: The farmer cultivates a small plot of land using simple tools and more labour. Climate with a large number of days with sunshine and fertile soils permit growing more than one crop annually (mainly rice). Practised in thickly populated areas of monsoon regions of Asia.
- Primitive subsistence agriculture: Includes:
- Shifting cultivation (slash and burn): Clearing a patch of land by felling trees and burning them, mixing ash with soil to grow crops like maize, yam, potatoes. Then moving on.
- Nomadic herding: Herdsmen move from place to place with their animals for fodder and water along defined routes (sheep, camel, yak, goats in Sahara, Central Asia, Rajasthan).
2. Commercial Farming
In commercial farming crops are grown and animals are reared for sale in the market. The area cultivated and amount of capital used is large. Most work is done by machines.
- Commercial grain farming: Crops (wheat, maize) are grown for commercial purpose. Practised in temperate grasslands of N. America, Europe, Asia. Large farms spread over hundreds of hectares.
- Mixed farming: The land is used for growing food and fodder crops and rearing livestock (Europe, Argentina, Australia).
- Plantations: A type of commercial farming where a single crop of tea, coffee, sugarcane, cashew, rubber, banana, or cotton is grown. Requires large amount of labour and capital.
🌾 PART 3: Major Crops
A large variety of crops are grown to meet the requirement of the growing population and supply raw materials for agro-based industries.
| Crop | Category | Requirements | Leading Producers |
|---|---|---|---|
| Rice | Food Crop (Major diet of world) | High temperature, high humidity, high rainfall. Needs clayey soil that retains water. | China, India, Japan, Sri Lanka |
| Wheat | Food Crop | Moderate temperature & rainfall during growing season. Bright sunshine at harvest. Well-drained loamy soil. | USA, Canada, Argentina, Russia, Ukraine, India (grown in winter) |
| Millets | Food Crop (Coarse grains) | Less fertile/sandy soils. Low rainfall. High to moderate temperature. | India (Jowar, bajra, ragi), Nigeria, China, Niger |
| Maize | Food Crop | Moderate temperature, rainfall, lots of sunshine. Well-drained fertile soils. | North America, Brazil, China, Russia, Canada, India |
| Cotton | Fiber Crop | High temperature, light rainfall, 210 frost-free days and bright sunshine. Black/alluvial soil. | China, USA, India, Pakistan, Brazil, Egypt |
| Jute | Fiber Crop (Golden Fiber) | High temperature, heavy rainfall, humid climate. Alluvial soil. | India, Bangladesh |
| Coffee | Beverage Crop | Warm and wet climate, well-drained loamy soil. Hill slopes are more suitable. | Brazil, Columbia, India |
| Tea | Beverage Crop | Cool climate, well-distributed high rainfall throughout year for tender leaves. Well-drained loamy soil and gentle slopes. | Kenya, India, China, Sri Lanka |
📈 PART 4: Agricultural Development

- This can be achieved by:
- Increasing the cropped area
- Increasing the number of crops grown
- Improving irrigation facilities
- Use of fertilisers and high yielding variety (HYV) of seeds
- Mechanisation of agriculture (using tractors, harvesers).
- Farming in India vs USA:
- A Farm in India: Small size (1.5 hectares), farmer buys HYV seeds from market, uses tractors on rent or bullocks, depends heavily on monsoon, takes credit from local banks, lack of storage facilities forces selling at unfavourable market times.
- A Farm in the USA: Much larger (250 hectares), farmer lives on the farm, relies heavily on scientific testing of soil, uses computers linked to satellites for precise fertilizer application, owns massive combine harvesters/tractors, stores grain in automated grain elevators. The farmer works like a businessman.
📌 Chapter Summary
- Economic Activities: Primary (agriculture/mining), Secondary (manufacturing), Tertiary (services).
- Subsistence Farming: For family needs. Can be intensive (using max labour on small land) or primitive (shifting cultivation/nomadic herding).
- Commercial Farming: For market sale. High capital, machines, large lands. Includes plantations (single crop focus).
- Major Crops: Rice (requires standing water/high temp), Wheat (loamy soil/moderate temp), Cotton (black soil/210 frost-free days), Jute ("Golden fiber", alluvial soil/heavy rain).
- Agricultural Development: Aimed at increasing production. Contrast between small, labour-intensive Indian farms and massive, highly mechanised US farms highlights differing levels of development.
