Subsistence farming is practised to meet the needs of the farmer’s family. Low levels of technology and household labour are used to produce a small output.
In Intensive subsistence the farmer cultivates a small plot of land using simple tools and more labour. More than one crop is grown annually, on the same plot, as the climate is favourable and the soil is fertile. Rice is the main crop; other crops include wheat, maize, pulses and oilseeds.
Intensive subsistence agriculture is prevalent in the thickly populated areas of the monsoon regions of south, southeast and east Asia.
What is Nomadic herding?
Nomadic herding is practised in the semi-arid and arid (dry) regions of Sahara, Central Asia and some parts of India, like Rajasthan and Jammu and Kashmir.
In nomadic farming, herdsmen move from place to place with their animals for fodder and water, along a definite route. The nomads move from place to place due to the restraints of the climate and land.
Sheep, camel, yak and goats are most commonly reared by the nomads. These animals provide milk, meat, wool, hides and other products to the herders and their families.
