“…Shelterbelt density is closely related to wind speed, which could change crop evapotranspiration and farmland soil erosion and thus affect crop yield [20,65]. Many previous studies [16,56] had reported the significant impact of shelterbelt density on crop yield. Our results further indicated that the variation pattern of shelterbelt density on yield increase effect also applied to the legacy effect.…”

“…Although the soil effect was found to be an important mechanism for crop yield through the study of the legacy effect, investigations into the influence of shelterbelts on farmland soil properties are rare [23] compared to a large number of shelterbelt-induced microclimate observation studies [1,12,65]. The existing models [16,19,71] mainly consider the microclimate effect on crop yield but ignore the shelterbelt-induced soil effect and its impact on yield, leading to an underestimation. It is necessary to conduct the investigation of soil structure and composition on the shelterbelt-adjacent farmland so as to provide a soil parameterization scheme for the models.…”

“…Microclimate modulation and soil quality improvement are considered the two main aspects favoring crop growth brought by a shelterbelt [12][13][14]. Although the mechanisms have been explored by many previous studies [2,15,16], the individual contribution of these two factors is still unclear. The shelterbelt-induced microclimate changes, such as the reduction of wind speed and the increase of air humidity, are short-term effects that disappear immediately when the shelterbelt is removed [17][18][19][20], while the soil effects, such as the improvement of soil quality, are accumulated processes that cannot vanish with shelterbelt-cutting [21][22][23].…”

Shelterbelts (or windbreaks) can effectively improve the microclimate and soil conditions of adjacent farmland and thus increase crop yield. However, the individual contribution of these two factors to yield changes is still unclear since the short-term effect from the microclimate and the accumulated effect from the soil jointly affect crop yield. The latter (soil effect) is supposed to remain after shelterbelt-cutting, thus inducing a post-cutting legacy effect on yield, which can be used to decompose the shelterbelt-induced yield increase. Here, we develop an innovative framework to investigate the legacy effect of post-cutting shelterbelt on corn yield by combining Google Earth and Sentinel-2 data in Northeastern China. Using this framework, for the first time, we decompose the shelterbelt-induced yield increase effect into microclimate and soil effects by comparing the yield profiles before and after shelterbelt-cutting. We find that on average, the intensity of the legacy effect, namely the crop yield increment of post-cutting shelterbelts, is 0.98 ± 0.03%. The legacy effect varies depending on the shelterbelt–farmland relative location and shelterbelt density. The leeward side of the shelterbelt-adjacent farmland has a more remarkable legacy effect compared to the windward side. Shelterbelts with medium–high density have the largest legacy effect (1.94 ± 0.05%). Overall, the legacy effect accounts for 47% of the yield increment of the shelterbelt before cutting, implying that the soil effect is almost equally important for increasing crop yield compared to the microclimate effect. Our findings deepen the understanding of the mechanism of shelterbelt-induced yield increase effects and can help to guide shelterbelt management.

“…In Hokkaido, Japan, windbreaks and shelterbelts have been established to prevent wind damage to crops (Tsuji et al, 2007), to prevent wind erosion (Tsuji et al, 2005), and to increase the temperature of farmland (Iwasaki et al, 2021). In Japan, there are two types of woodlands for wind protection, which each requiring completely different management systems.…”

A considerably large number of shelterbelts were established in Japan to increase crop yields in agricultural landscapes. Shelterbelt landscapes have multiple functions; they not only help to control wind damage but also to conserve biodiversity, including forest and grassland species. However, previous studies on biodiversity conservation in shelterbelts, and the target taxa were limited since this aspect of shelterbelts has not received much attention in Japan. This study examines the effects of shelterbelts and their regeneration on the diversity of butterflies and flowering plants in the Tokachi region of Hokkaido, Japan. Using a transect method, we compared environmental factors, butterfly, and flowering plant diversity in four habitats: inside forest, forest edge, regeneration sites, and semi‐natural grasslands which include shelterbelts and surrounding landscapes. There were significant differences in photosynthetically active radiation (PAR) among habitats, with higher PAR corresponding to higher numbers of butterfly species and individuals, and flowering plant species and flowers. Nonmetric multidimensional scaling results also showed that the species composition of flowering plants and butterflies differed among habitats. In addition, indicator value analysis showed that semi‐natural grasslands and regeneration sites were characterized by endangered butterflies and their host plants. Our results indicated that shelterbelt regeneration and the surrounding environment (e.g., semi‐natural grasslands) contributed to the diversity of butterflies and flowering plants, including endangered species. Future studies evaluating the diversity of various taxa would provide a more comprehensive understanding of the effects of shelterbelts on biodiversity conservation.

Winter cold wave adaptation strategies in hot climates due to climate change didn’t receive the deserved attention from previous studies. Therefore, this study comprehensively investigates the impact of various windbreak parameters on mitigating winter cold stress in hot steppe-arid climate. A microclimate model for a residential campus was built and validated through on-site measurement on a typical winter day to assess thirty-two scenarios for tree characteristics and spatial configuration windbreak parameters based on PET, wind speed, and Air Temperature (AT). Moreover, four configurations, that had best results on mitigating cold stress in winter, were tested during typical summer conditions to couple the assessment of cold and hot seasons. Additionally, environmental analysis for all scenarios was conducted. The results revealed that the most effective parameters for mitigating cold stress are tree distribution, Leaf Area Density (LAD), row number, spacing, and shape. Double rows of high LAD and medium height trees with small spacing yielded the best cold stress mitigation effect. Furthermore, the windbreak reduced the cold stress in the morning and night by 19.31% and 18.06%, respectively. It reduced AT and wind speed at night by 0.79 °C and 2.56 m/s, respectively. During summer, very hot PET area was reduced by 21.79% and 19.5% at 12:00 and 15:00, respectively.
