Jhum cultivation is also known as slash and burn agriculture in the hills of the north-east India. According to recent estimates, India’s 0.59 percent of the total geographical area is under shifting cultivation. The effects of shifting cultivation are devastating and far-reaching in degrading the environment and ecology of these regions. The earlier 15–20 years cycle of shifting cultivation on a particular land has reduced to two or three years now. This has resulted in large-scale deforestation, soil and nutrient loss, and invasion by weeds and other species. The indigenous biodiversity has been affected to a large extent. The current statistics say that India’s largest area under shifting cultivation is in the state of Odisha.
