| Summary: | In many parts of the world, crop damage is the primary problem caused by wind erosion. Tree shelterbelts are established to reduce wind speed, thus reducing stress on plants growing to their leeward side. Shelterbelts usually consist of combinations of trees, shrubs, annual crops, or grasses. This chapter reviews the microclimatic modification by tree shelterbelts and their effects on the growth and development of crops in agroforestry systems. Today, tree shelterbelts are receiving renewed interest as part of the movement to create a more sustainable agroforestry system. The beneficial effects of shelterbelts in crop production in agroforestry systems is well documented, including increased yields due to the favorable growing condition and improved microclimate. Various researchers reported improved growth of crops to the leeward side of shelterbelts. However, the results vary considerably, depending on shelterbelt design, crop species, and climate conditions. The literature on shelter effects on crop growth indicates that plant growth and yield are beneficially affected by wind shelter. Tree shelter is shown to increase the growth and yield of various horticultural and field crops in the 6%–56%. The review suggests a positive relationship between tree shelterbelts and crop growth and development attributed to modifying microclimate conditions. This will hopefully provide strategies for farmers, natural resources managers, and rural planners to make informed decisions in incorporating tree shelterbelts for sustainable agroforestry. © 2024 Elsevier Inc.
