Shelterbelts

Belts of trees, planted in a rectangular grid pattern or in strips within, and on the periphery of, farmland to act as windbreaks. Shelterbelts are a specific type of agroforestry system that help reduce natural hazards including sandstorms, wind erosion, shifting sand, droughts and frost.

They also improve the microclimate (reduced temperature, wind speed, soil water loss and excessive wind-induced transpiration) and create more favourable conditions for crop production. The establishment of shelterbelts plays a crucial role in the sandy drylands that are affected by wind and resultant desertification.
