Shifting cultivation is an agricultural practice in which a plot of land is temporarily cultivated and then abandoned to allow vegetation to grow freely while the cultivator moves to another plot. It is also known as slash and burn' agriculture. The process involves clearing a land parcel by felling and burning trees. Shifting cultivation has both positive and negative environmental impacts. On the positive side, it reduces the intensity of land use and the rate of environmental degradation. However, its negative impact includes loss of soil fertility, accelerated deforestation, and out of control forest fires.
