The system in which a farmer uses a piece of land for a period and abandons it for another land is called "shifting cultivation". In this system, a farmer will clear a piece of land for farming, use it for a few seasons until the soil becomes less fertile, and then move on to another piece of land and repeat the process. This allows the abandoned land to recover its fertility and biodiversity. Shifting cultivation is often used by small-scale farmers in tropical regions where the soil is less fertile and where there are few other options for agriculture.
