Control of Land Degradation
1. Restoring forest and grass cover to check erosion and floods.
2. Shifting cultivation can be replaced by crop rotation, mixed cropping, plantation cropping to improve fertility and meet larger demands.
3. Shifting sand can be controlled by mulching(use of artificial protective covering) or by planting trees as wind breaks.
4. Salt affected lands can be recovered by leaching them with water.

Land and water management in India
| India’s total land mass of this half is covered by waste land. |
305 million hectares (ha) |
| Land under urban and productive use |
18 million ha |
| Rocky and hilly area |
21 million ha |
| Culturable waste land |
17 million ha |
| Fallow land |
23 million ha |
| Forest land and pasture land |
83 million ha |
| Agriculture land |
143 million ha |
|
Due to high population per capita available land is 0.48ha.
The cope up with the growing scantiness of land we should treat catchment areas on environmentally sound basis. Land must be conserved by planting economically and socially useful trees and grasses chosen according to edaphic and climatic conditions and local needs. Proper drainage and desalination practices can overcome water logging and salinity.
