AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
Shifting cultivation is a mode of farming long followed in the humid tropics of Sub-Saharan Africa, Southeast Asia, and South America. In the practice of “slash and burn”, farmers would cut the native vegetation and burn it, then plant crops in the exposed, ash-fertilized soil for two or three seasons in succession. It increases soil erosion rate.
