How can we stop, reduce or prevent desertification?

Hint: Desertification is a type of land degradation in drylands in which biological productivity is lost due to natural processes or induced by human activities whereby fertile areas become increasingly arid.

Complete answer:
 Variations in climate and Human activities are the two main causes of desertification. Cutting of forest or natural vegetation be humans for fuel wood. Mass scale agriculture in the area with less remaining of nutrients supplements leads to the vanish of fertility of that area.

Important steps to control desertification:
- Integrating land and water management to protect soils from erosion, salinization, and other forms of degradation irrigation of land and water management should be done frequently.
Protection of vegetative cover, which can be one of the best ways for soil conservation against wind and water erosion.
- Use of land should be integrated for grazing and farming where conditions are favorable, allowing for a more efficient cycling of nutrients of the agricultural systems.
- Applying a combination of traditional practices with locally acceptable and locally adapted land use technologies.
- Managing dryland resources effectively and giving local communities the capacity to prevent desertification. livelihoods should not be dependent on traditional land uses, there should be some alternative methods such as dryland aquaculture, greenhouse agriculture and tourism-related activities..

Note: Sometimes geographic reasons are the reason for desertification. The Thar desert of India had lost its cloud holding capacity millions of years ago due to the Aravalli hills geographical position.
