The system in which a farmer uses a piece of land for a period and then abandons it for another land is called shifting cultivation. This system involves clearing a piece of land, planting crops on it for a few years until the soil fertility declines, and then abandoning it to allow the land to regenerate naturally. The farmer then moves on to a new piece of land and repeats the process. This system is often used in areas with poor soil fertility and limited access to fertilizers, as it allows the farmer to continue to produce crops without exhausting the land completely. However, shifting cultivation can lead to soil erosion and loss of biodiversity if not managed properly.
