In arid areas, where the availability of water is limited, the most effective method of soil conservation is the shelter belt. A shelter belt is created by planting a row of trees and shrubs along the boundaries of agricultural fields or in strategic locations to protect the soil from erosion caused by strong winds. The dense vegetation acts as a barrier, reducing the speed of the wind and preventing it from eroding the topsoil. Additionally, the shelter belt provides shade, reducing evaporation and conserving moisture in the soil. This method is particularly effective in arid areas because it helps retain the limited water resources and prevents soil degradation. Therefore, option 2, shelter belt, is the correct answer.
