Jhum cultivation is one of the methods of farming that is mainly practised in northeast India. It is also called shifting cultivation. Jhum cultivation is a method in which the farmers or people of the forest shift their agricultural field from one place to another by clearing the forest with fire. Furthermore, the burned and cleared forest provides ash for manure. In addition, this fertile soil also provides high yields. After continuous cultivation, the soil loses its fertility, and weeds increase. Therefore, the land is then left fallow for years, and these people move to another land for cultivation, repeating the same process of clearing the forest. Meanwhile, the left land is converted into a secondary forest. After a few years, these secondary forests can also be reused for cultivation.
