in India is known as jhum cultivation.
Technique and crops
In the month of January, the jhummias cut down the forest on the slope of the hill. Afterwards, they clean the land and dry the wood, bamboo and plants they have cut down in the sun. Later around March–April, the dried material is burnt and made suitable for jhum cultivation.

Jhum cultivation requires that farmers move their plots from year to year to allow the land to recover. Previously, natural forests of the hills were kept uncultivated for a long time. In recent times, however, the uncultivated period has been dangerously reduced from the traditional ten years to two to three years. This is due to depletion of agricultural land and loss of available land due to population pressure, the
Kaptai reservoir, and large-scale non-tribal settlement.
Drawbacks

habitat, and flooding of rivers and lakes. As a result, production declines so much that a Jhummia family cannot survive in one place. The most widely followed minimum seven to eight-year cycle is currently reduced to three to four years which is not at all sufficient. Due to these reasons, the crop yield has now declined at a huge rate, making it critical to devise suitable alternatives to jhum cultivation.
