Explain the ‘slash and burn’ agriculture. How is it known in different parts of the country?

Under this system, farmers clear a patch of land and produce cereals and other food crops to sustain their family. As the fertility of the soil decreases, the land is abandoned. The farmers move to new areas and clear a fresh patch of land for cultivation. It is known as ‘shifting agriculture’. The shifting of farmers to new area allows nature to replenish the fertility of the soil through natural processes. As farmers do not use fertilisers and high yielding variety of seeds, the land productivity is low.
