The two main types of farming are:Subsistence farming and commercial farming.
Subsistence farming is practised solely to meet the needs of the farmer’s family. Therefore, the practices involved are usually old- fashioned. Use of modern technology is minimum and most work is done by household labour.
In intensive, subsistence agriculture, simple tools and huge labour are used by a farmer to cultivate a small plot of land. More than one crop is grown annually in favourable conditions. Rice is the major crop. This form of agriculture is seen in the thickly populated areas of the monsoon regions of south, south-east and east Asia. Shifting cultivation is a class of primitive subsistence agriculture. In this, a plot of land is cleared by felling the trees and burning them. The ashes are then mixed with soil and crops are grown. After some time, the land is abandoned and the farmers move to a different place. This type of farming is common in the thickly forested areas of the Amazon basin, tropical Africa, parts of south-east Asia and north-east India. It is also called “slash and burn” agriculture.
Nomadic herding refers to the practice in which herdsmen move from place to place with their animals for fodder and water. Animals usually reared are the yak, sheep, camel and goats.
