What are the types of land degradation?
For the purpose of this study, the many and varied processes of land degradation have been grouped into six classes: water erosion, wind erosion, soil fertility decline, salinization, waterlogging, and lowering of the water table.
What are the effects of land degradation?
Its impacts can be far-reaching, including loss of soil fertility, destruction of species habitat and biodiversity, soil erosion, and excessive nutrient runoff into lakes. Land degradation also has serious knock-on effects for humans, such as malnutrition, disease, forced migration, cultural damage, and even war.

Answer: Terrace farming is not responsible for land degradation.
What are the causes of land degradation how we solve this problem?
Afforestation and proper management of grazing can help to check land degradation. Planting of shelter belts help in checking the sand causing land degradation near the deserts. Overgrazing can be checked and avoided. Stabilisation of sand dunes by growing thorny bushes can also check land degradation.
