Major Causes of Deforestation Shifting cultivation In this practice a patch of land is cleared, vegetation is burned, and the ash is mixed with the soil thus adding nutrients to the soil. This patch of land is used for raising crops for two to three years, and the yield is modest. Then this area is abandoned and is left to recover its fertility, and the same practice is repeated elsewhere on a fresh piece of land. This agricultural practice has become unsustainable due to rapid increase in population pressure in the forested areas. 521 views12:32
