Question
How Jhum cultivation has lead to deforestation in recent years?
✓

Answer

  1. Because in the Jhum cultivation, the forest trees are burnt to make space for farming and for obtaining ash as fertilizer, it leads to loss of precious forest cover.
  2. Once the trees are destroyed, farmers use this land for farming. After the cultivation and harvest, the land is left barren.
  3. It is used for cattle grazing.
  4. Since long period is required for the recovery of land back into forest patch, the deforestation results.
