When the productive potential of soil, especially on arid or semiarid land, falls by 10% or more because of prolonged drought and human activities, occurs. When the productive potential of soil, especially on arid or semiarid land, falls by 10% or more because of prolonged drought and human activities, occurs.

desertification

Explanation:

Desertification is a type of land degradation in which a relatively dry land region becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife. It is caused by a variety of factors, such as climate change and human activities.occurs. When the productive potential of soil, especially on arid or semiarid land, falls by 10% or more because of prolonged drought and human activities, desertification occurs.

desertification

Explanation:

Desertification can be described or explained as a situation whereby the fertile lands becomes desert due to climatic variation such as drought, and human activities like deforestation, overgrazing and tillage practices that makes the soil to be vulnerable to wind or water.

This is known to be common in regions known to be arid or semiarid. Arid region can be described as a region that receives little precipitation, that is ,less than 10 inches (25 centimeters) of rain per year, while Semi-arid regions receive 10 to 20 inches (25 to 50 centimeters) of rain per year.

In this case, there are things that can be done to prevent desertification from occurring. These include

* Protecting the vegetative cover, which can be a major instrument for soil conservation against wind and water erosion.

* Integrating the use of land for grazing and farming where conditions are favorable, allowing for a more efficient cycling of nutrients within the agricultural systems.

* Integrating land and water management to protect soils from erosion, and other forms of degradation.
