Answer Details
Semi-arid areas are regions that receive very little rainfall and are prone to wind erosion. Wind erosion is a process that occurs when the wind picks up soil particles from the surface and moves them away, which can lead to the loss of topsoil and decreased fertility.
One solution to wind erosion in semi-arid areas is the establishment of "shelter belts." Shelter belts are rows of trees or shrubs planted in the direction of the prevailing wind. They act as a barrier, reducing wind speed and protecting the soil from erosion.
The trees and shrubs in the shelter belts also provide other benefits. They can help to reduce the impact of sandstorms, provide shade for livestock, and create habitats for wildlife. Additionally, they can help to improve soil quality by adding organic matter and nutrients through their fallen leaves and other debris.
In contrast, crop strips, terrace bounds, and diversion channels are also methods used to control erosion, but they are not specifically designed to combat wind erosion in semi-arid areas. Crop strips are used to reduce water erosion on sloping land, terrace bounds are used to reduce soil loss on steep slopes, and diversion channels are used to redirect water flow and prevent flooding.
