Detailed explanation-1: -Apart from these problems of human misery, shifting cultivation, as currently practised in many areas, is wasteful of scarce land resources and frequently leads to intolerable erosion, particularly of hillsides and sloping lands.
Detailed explanation-2: -But, cases of the transition from shifting cultivation to more intensive land uses reveal drastic negative impacts on the ecosystems leading to permanent deforestation and biodiversity loss including disappearance of local varieties and breeds of plants and animals.
