“…The PWER gradually decreased in different land types (Table S4). Although this pattern differs from those of other regions (Table 2; Mandakh et al, 2016;Touré et al, 2019;Qi et al, 2008), it is consistent with the law of wind erosion changes in the arid region of northwest China (Table 2; Chi et al, 2019;Gong, 2014;Li et al, 2020;. The traditional opinion is that cultivated land is more vulnerable to wind erosion than grassland because farming activities (ploughing, leveling beds, planting, etc.)…”

To reduce the damage caused by wind erosion, the accurate evaluation of wind erosion dynamics and revelation of their driving mechanism are crucial. In this study, the revised wind erosion equation was applied for the estimation of the potential wind erosion rate (PWER) from 1982 to 2015 in the Hexi region, China. Geographic detection, variable control, and correlation analysis were used to determine the contributions of climatic factors and land use patterns to wind erosion. The results showed that the PWER decreased remarkably from 1982 to 2015 (annual average of 67.7 t ha −1 yr −1 for the entire region). Each year a severe and a mild wind erosion period occurred from October to May and from June to September, respectively. Spatially, the PWER was strong in the eastern, western, and northern regions (especially in the west) and less severe in the central and southern regions, and there was a decreasing tendency in 95% of the area. The PWER of Mongolia (north) was highest, while that of Minle was lowest. Climatic factors primarily determined the PWER in Hexi, among which wind speed was the main factor controlling the intensity of wind erosion. The area with a land use inhibiting wind erosion (3,240 km 2 ) was four times larger than that with a land use promoting wind erosion (800 km 2 ). Meanwhile, the total area with a changing land cover was less than 2% of the study area; therefore, this factor did not significantly affect the PWER in the short term.

“…Climate change exacerbates land degradation by influencing several of the processes that alter soil quality and quantity in a way that hampers agricultural yield. For example, climate change accelerates topsoil loss by increased erosion (Li et al, 2020). Topsoil is endangered by both wind and water erosion (Li et al, 2020; Sulaeman & Westhoff, 2020).…”

Climate change‐triggered land degradation and planetary health: A review

et al. 2021

Land is a vital natural resource for human socio‐ecological wellbeing. Around the world, land is being degraded due to various natural and anthropogenic factors such as flooding, wind erosion, agriculture and human settlement, and anthropogenic climate change. While significant research has been conducted on the separate dyads of: (1) anthropogenic climate change and land degradation and (2) land degradation and health, limited consideration has been given to the cause‐and‐effect relationships between anthropogenic climate change‐triggered land degradation and planetary health consequences. Using a systematic literature review and the driving force, pressure, state, exposure, effect (DPSEE) framework, this study synthesizes the complex causal relationships of anthropogenic climate change‐triggered land degradation and its planetary health consequences. Our findings demonstrate that anthropogenic climate change has induced and accelerated natural and anthropogenic land degradation through an array of pathways, resulting in planetary health consequences that can be grouped into six categories: (1) food and nutritional insecurity, (2) communicable and noncommunicable diseases, (3) livelihood insecurity, (4) physical and mental health, (5) health hazards related to extreme weather events, and (6) migration and conflict. Interlinkages exist between these six planetary health impact categories, adding to the complexity of the causal pathways. These collective impacts are hampering the realization of the UN Sustainable Development Goals around the world. The findings of this study and our DPSEE framework can help policymakers identify and integrate actions to better manage the planetary health impacts of climate change‐induced land degradation.

“…The long dormant season, along with strong winds in spring, makes exposed croplands more vulnerable to wind erosion, especially those without crop residues or wind breaks [12][13][14][15]. The wind erosion modulus of rain-fed cropland will continue to increase more than that of grassland under future climate change scenarios [16]. Land degradation caused by wind erosion reduces soil productivity and weakens ecosystem services such as soil conservation and crop production [17].…”

Understanding soil erosion responses to cropland expansion/shrinking plays a crucial role in regional agriculture sustainability development in drylands. We selected Inner Mongolia, a typical water resource constraints region with acute cropland expansion, as the study area in China. Spatial cropland evolution and its impact on wind-driven soil erosion were investigated with the help of field sampling data, remotely sensed retrieved data, and the revised wind erosion model (RWEQ). Results showed that the cropland area of Inner Mongolia presented an increased growth trend, with a net increase area of 15,542.9 km2 from 1990 to 2018. Cropland characteristics in Inner Mongolia presented continuous growth in its eastern region, basically constant growth in its central region, and declined in its western region. Most cropland declines occurred after 2000 when the Grain for Green project began, which means that acute cropland expansion happened from 1990 to 2000. The soil wind erosion modulus showed a net increase with cropland expansion. The reclamation of forests and grasslands contributed to an increase of 5.0 million tons of the soil wind erosion modulus, 80% of which was produced in the eastern part of the region. The conversion from croplands to grasslands/forests caused a decrease of approximately 2.7 million tons, 62% of which was in the east and 25% in the west of the region. Considering the constraints of water shortage and over-exploitation of groundwater, we provide a path based on a balance between ”resource-production-ecosystem” to achieve ecologically sustainable agriculture development in the drylands of China.
