The correct answer is: d) Shifting cultivation.
Shifting cultivation, also known as swidden agriculture or slash-and-burn agriculture, is a traditional agricultural system in which the natural vegetation is cleared and the soil is cultivated for a short period of time. After a few years, the land is abandoned and allowed to regenerate, while the farmers move on to clear a new area.
Shifting cultivation is a sustainable form of agriculture that has been practiced for centuries by many different cultures around the world. However, it is often misunderstood and criticized by outsiders. Some people believe that shifting cultivation is a destructive practice that leads to deforestation and soil erosion. However, this is not always the case. When practiced correctly, shifting cultivation can be a sustainable way to manage land and produce food.
