Wind erosion occurs whenever conditions are favorable for detachment and transportation of soil material by wind. Five factors influence the intensity of soil erosion:
1. soil erodibility,
2. surface roughness,
3. climatic conditions (wind velocity and humidity),
4. length of exposed surface,
Little can be done to change the climate of an area but it is usually possible to alter one or more of the other factors to reduce erosion. Regardless of the type of procedure, the aims or principles for success in control of soil drifting are the same, in all areas where wind erosion occurs. These are
• to reduce wind velocity near the ground level below the threshold velocity that will initiate soil movement,
• to remove the abrasive material from the wind stream,
• to reduce the erodibility of the soil.
Any practice that accomplishes one or more of these objectives, therefore, will reduce the severity of wind erosion. In this section, the most common measures are described. More detailed information on wind erosion mechanics and methods for wind erosion control can be found in the literature [1, 11, 39, 46-58].
