The ashes are then mixed with the soil and crops are grown. After the land has lost its fertility, it is abandoned. The farmers then move to a new place.
Disadvantages of shifting cultivation:

Loss of fertility of a particular land
Leads to Soil erosion
Burning of trees causes air pollution
Insufficient cultivation of crops for a large population.

(ii) Subsistence farming and intensive farming.
Answer: Subsistence farming is a type of farming that the farmer practices to meet the needs of his family. The cultivation of crops is done for personal consumption.

Rice, wheat, maize, pulses and oilseeds are the crops grown in this type of farming. Intensive subsistence agriculture is prevalent in the thickly populated areas of the monsoon regions.
