The kaingin system of farming is a traditional method of slash-and-burn agriculture commonly practiced in Southeast Asia. It involves clearing land by cutting down vegetation and burning it to create nutrient-rich soil for planting crops. While effective in the short term, this practice can lead to deforestation, soil degradation, and loss of biodiversity.
