“…In the aforementioned study (32), soil moisture content exerted a strong influence on the rate of wind erosion, accounting for 13% of the variation in erosion. Last but not least, vegetation cover can significantly reduce the magnitude of erosion caused by surface runoff.…”

Traditional Chinese approaches to ecosystem restoration have focused on afforestation as an important tool for controlling desertification. However, the long-term results of this practice increasingly show that these projects are actually increasing environmental degradation in arid and semiarid regions, with ecosystems deteriorating and wind erosion increasing. Rather than focusing solely on afforestation, it would be more effective to focus on re-creating natural ecosystems that are more suitable for local environments and that can thus provide a better chance of combating desertification.Arid and semiarid regions make up ~40% of the earth's land surface and are home to ~20% of the human population, but these areas are increasingly being affected by desertification (1).

The decreased vegetation cover can offset this advantage by increasing wind erosion.

“…a. The relationship between the mechanical properties of the soil and the rate of wind erosion is exponential, as has been verified on the basis of the plot-sized measurements (Li et al, 2005;Skidmore, 1994). The relationship between the two factors is "J-shaped" and monotonically increasing (Fig.…”

“…The relation between the wind speed and the rate of wind erosion is logarithmic (Böhner et al, 2003;Li et al, 2005). However, due to the available data, the frequency of erosive winds (number of days with a maximum daily wind speed > 9 m s −1 ) was used.…”

Abstract. In Hungary, wind erosion is one of the most serious natural hazards. Spatial and temporal variation in the factors that determine the location and intensity of wind erosion damage are not well known, nor are the regional and local sensitivities to erosion. Because of methodological challenges, no multi-factor, regional wind erosion sensitivity map is available for Hungary. The aim of this study was to develop a method to estimate the regional differences in wind erosion sensitivity and exposure in Hungary.Wind erosion sensitivity was modelled using the key factors of soil sensitivity, vegetation cover and wind erodibility as proxies. These factors were first estimated separately by factor sensitivity maps and later combined by fuzzy logic into a regional-scale wind erosion sensitivity map. Large areas were evaluated by using publicly available data sets of remotely sensed vegetation information, soil maps and meteorological data on wind speed. The resulting estimates were verified by field studies and examining the economic losses from wind erosion as compensated by the state insurance company. The spatial resolution of the resulting sensitivity map is suitable for regional applications, as identifying sensitive areas is the foundation for diverse land development control measures and implementing management activities.

“…In areas of reclaimed grasslands, the variations in wind activity were also a key factor that controlled sandy desertification, because the vegetation cover during the windy season is very low [57], and provides little protection for the erodible fine particles against the wind; as a result, these particles are eroded and the surface soils are impoverished. At present, especially in arid and semiarid China, most studies have mainly focused on spatial variations in the intensity of wind erosion [97,98], and there have been few studies of its association with sandy desertification.…”

Sandy desertification is both an inherently interesting bioscience and geoscience topic and an important topic from the perspectives of the ecological environment and food security. It has therefore increasingly attracted the attention of the public, in addition to researchers, government officials, and international organizations. This paper reviews the development of knowledge on sandy desertification, research progress in understanding the physical and biological processes involved in sandy desertification, and the significance of wind activity in determining the increases and decreases in sandy desertification. Based on this review of current research on the mechanisms and processes of sandy desertification, combining geological and biological sciences appears likely to improve our understanding of this complex system, thereby providing a more holistic understanding of sandy desertification at a range of temporal and spatial scales. aeolian desertification, sandy desertification, wind activity, dune activity, physical processes, biological processes Citation:Wang X M.
