Question

Suggest some measures to prevent desertification.

Answer 1

Preventive actions include:Integrating land and water management to protect soils from erosion, salinization, and other forms of degradation.
Protecting the vegetative cover, which can be a major instrument for soil conservation against wind and water erosion.

Answer 2

In order to prevent and reverse desertification, major policy interventions and changes in management approaches are needed. Such interventions should be implemented at local to global scales, with the active engagement of stakeholders and local communities.

Societal and policy actions need to adjust to the degree of desertification that a society faces or is likely to face. In areas where desertification processes are at the early stages or are relatively minor, it is possible to stop the process and restore key services in the degraded areas. Prevention is a lot more cost-effective than rehabilitation, and this should be taken into account in policy decisions.
