Desertification, also called desertization, the process by which natural or human causes reduce the biological productivity of drylands (arid and semiarid lands).

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

ANSWER ⋇⋆✦⋆⋇　

Removal of top layer of soil exposes the lower, hard layers of soil. This soil has less humus and is less fertile. Gradually, the fertile land gets converted into deserts. This is called desertification.

measures that can be taken to prevent Desertification

• 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.
• Turning to alternative livelihoods that do not depend on traditional land uses, such as dryland aquaculture, greenhouse agriculture and tourism-related activities, is less demanding on local land and natural resources, and yet provides sustainable income.
• Applying a combination of traditional practices with locally acceptable and locally adapted land use technologies.
• Giving local communities the capacity to prevent desertification and to manage dryland resources effectively.
