Answer:
Shelter belts can reduce and in some cases prevent wind erosion by intercepting wind and consequently reducing wind speed as wind passes through or over the belt. Even narrow or open belts can reduce wind speed for a distance many times the height of the belt and therefore have a considerable impact on wind erosion.
An example is where wind speed at 0.5mts above the ground, at a distance of 12 times the height (12H) of a shelter belt was measured at a modest 60% of the open wind speed. The erosive force of the wind there was estimated to be reduced to 25% of that in open areas (Bird et al. 1992).
