What is shifting cultivation? What are its disadvantages?

Answer: Shifting cultivation or Slash-and-burn cultivation is generally practiced in dense forest areas. These are  areas with heavy rainfall and rapid vegetation regeneration. Land is wiped out by cutting down trees and burning them. The ashes are then mixed with the earth.

After the soil loses  fertility, the land is abandoned and the farmers move to  new plots. The main drawback of shifting cultivation is that many trees are cut down in the forest. This increases the fertility of the soil and causes soil erosion.
