• Climate conditions such as monsoon rainfall support multiple cropping.
• Human factors include labour, technology, irrigation and capital.

3. Types of farming

• Farming is mainly divided into subsistence farming and commercial farming.
• The classification depends on purpose of production and scale.
• Subsistence farming focuses on family needs.
• Commercial farming aims at market sale.
• Both types depend on climate and resources.

4. Subsistence farming

• Practised to meet the needs of the farmer’s family.
• It involves small land holdings and simple tools.

• More than one crop is grown in a year.
• Major regions include India, China and Bangladesh.
• Main crops are rice, wheat and pulses.
• Rice cultivation is common in West Bengal and Bihar.

6. Primitive subsistence farming

• It is an old form of farming practised with simple tools.
• Includes shifting cultivation and nomadic herding.
• It depends on natural fertility of soil.
• Production is low and uncertain.
• It often leads to environmental issues.

7. Shifting cultivation

• Forest land is cleared and burnt for cultivation.
• Land is used for a few years and then abandoned.
• It is called Jhumming in Assam and Meghalaya.
• It is known as Milpa in Mexico, Roca in Brazil and Ladang in Malaysia.
• It causes deforestation and soil erosion.

8. Nomadic herding

• People move with animals in search of fodder and water.
• Practised in the Sahara Desert, Central Asia and Rajasthan.
• Common animals include sheep, goat, camel and yak.
• It depends on climatic conditions.

• Livestock provides manure and income.
• Practised in UK, France and New Zealand.
• It ensures balanced income for farmers.
• It reduces risk of crop failure.

12. Plantation agriculture
