The problems caused by wind blown sand can be tackled in four ways: (1) by enhancing its deposition, using ditches, fences or tree belts; (2) by enhancing its transport, using streamlining techniques, creating a smooth texture over the land surface, or by erecting panels to deflect the air flow;

Millions of hectares of crops are exposed to wind blown sand abrasion each year, and in many instances the damage is thought to be severe enough to require replanting. The goal of this study was to determine the effects of wind blown sand abrasion duration on cotton (Gossypium hirsutum L.) seedlings.
