SHELTERBELTS Meaning and
Definition
-
Shelterbelts, also known as windbreaks or windshields, are rows of tall and densely planted trees, shrubs, or other vegetation specifically designed to protect crops, livestock, buildings, or other structures from wind erosion or damage caused by strong winds. Their primary purpose is to create a barrier that reduces wind speed and turbulence, thus providing a more favorable microclimate within their vicinity.
Generally, shelterbelts are strategically placed perpendicular to the prevailing wind direction, commonly found in areas with wind or soil erosion issues. The vegetation in shelterbelts functions as a barrier, slowing down and redirecting the wind, which helps to minimize soil loss, protect against windbreak for agricultural fields, reduce wind chill on livestock, prevent wind damage on buildings, and even improve the quality and yield of crops by reducing moisture evaporation.
Shelterbelts are often established using a combination of trees, shrubs, and grasses that can effectively intercept and diffuse the wind, while also providing other environmental benefits such as wildlife habitat and aesthetic appeal. Popular tree species used in shelterbelts include evergreens like spruces, pines, or firs, as they maintain their foliage year-round. Deciduous trees like willows and poplars may also be used, as they provide additional benefits like shade during the summer months.
Overall, shelterbelts play a crucial role in sustainable land management and provide a range of benefits, making them an essential component of protecting ecosystems, agriculture, and infrastructure from the damaging effects of strong winds.
