Summary: The study in the desert steppe of Inner Mongolia, China, found that finer soil particles generally had higher SOC contents, leading to a proposed method to calculate SOC content in aeolian sediment. The calculated results were highly consistent with the measured results, providing a more precise estimation of SOC loss induced by wind erosion. Simulated results showed SOC loss induced by dust emissions ranging from 0 to 39 g/m(2)/y during the period of 2001 to 2017, which could be valuable for carbon budget estimation in the desert steppe.

Summary: This study compared the dust emission ability of sand desert, Gobi, and farmland in northern China. Results showed that under low friction velocities, sand desert had the greatest emission ability, but as wind speed increased, farmland gradually exceeded sand desert in emission ability. This highlights the importance of considering wind velocity and dust size when comparing the emission ability of different land types.

Summary: Many important ecosystem services exhibit spatial flow characteristics, which are essential for environmental process studies. The Baijitan Nature Reserve experienced an increase in vegetation coverage and a decline in wind speed over the past 20 years. Sand erosion only affected the nature reserve and adjacent communities, with limited impact on downstream administrative regions.

Summary: Urmia Lake, the second hypersaline lake in the world, has experienced an increase in susceptible areas to wind erosion due to decreasing water input caused by human activities. The study found that wind erosion on the edge of Urmia Lake was influenced by the water level of the lake and conservation practices, resulting in a decreasing trend in wind erosion rate from 2017 to 2019.

Summary: This study investigates the dust concentration, emission characteristics, and physical factors of sand dunes in the Taklimakan Desert (TD). The results show that dust emissions in the TD dunes are larger than in other areas and have a good correlation with friction velocity. The wind speed at the top of dunes is higher, leading to the accumulation of PM10, and the turbulence weakens after sunset, contributing to the retention of dust in the air.

Summary: The rapid drying of the Aral Sea has caused complex environmental changes and a significant amount of aeolian dust to be released from the exposed bottom. This study used models to investigate the emission and transport characteristics of the Aral Sea dust. The results show that the dust emission is concentrated in the eastern Aral Sea basin and exhibits seasonal variation, with the highest value and widest spatial range in spring. The dust can be transported over 4,000 km and affect a land area of more than 38.5 x 106 km2, reaching as far as the Arctic Ocean, Iran, the Atlantic Ocean, and the Pacific Ocean.

Summary: This study in the GCC region near two major airports reports seasonal variations in meteorological parameters, atmospheric dust, and dust-borne heavy metals concentrations. The concentrations of heavy metals, PM2.5, and PM10 fluctuated with meteorological conditions, with potential harm to human health. The chemical correlation between atmospheric dust and regional desert sand implies the localized origin of smaller dust particles.

Summary: The study found significant changes in vegetation and soil properties at different degradation stages of alpine grasslands in the source region of the Yellow River. Soil bulk density was the main driver for changes in plant biomass and diversity at the intact to moderate degradation stages, while soil organic carbon and nitrate nitrogen content became the main drivers at severe and very severe degradation stages.

Summary: This study used remote sensing and climate data to analyze the restoration and reversal of aeolian desertification in the Shiyang river basin. Through land rehabilitation and watershed management projects, the area of farmland increased, the area of shifting sand decreased, and the water area expanded. The severity of desertification in the Shiyang river basin is influenced by climate and land-use management systems. Overall, the area of Aeolian Desertified Land (ADL) decreased, and the intensity of desertification reversed in some parts of the basin, but there were also areas of land degradation. Land management, water allocation, and conservation measures play a crucial role in reversing desertification and maintaining a sustainable ecosystem in the Shiyang river basin.

Summary: This study evaluates the stability of the main sandy land regions in Northern China by combining time-series Net Primary Productivity (NPP) data and the AutoRegression (ARx) model. The results show strong correlations among stability metrics, such as a significant negative correlation between resilience and resistance. The unstable low or moderate-cover grassland and slightly desertified area require more attention to meet the challenges of more intense climate extremes in the future.

Summary: Increasing salinization poses a threat to the growth of halophytes in saline habitats. Soil beneficial microorganisms, such as arbuscular mycorrhizal fungi (AMF) and plant growth-promoting rhizobacteria (PGPR), have the potential to promote salt tolerance of halophytes. However, the responses of different halophytes to microbial inoculations vary. Co-inoculation of AMF and PGPR can enhance biomass accumulation, nutrient absorption, ion homeostasis, and selective ion transportation in halophytes, reducing the negative effects of salt stress.

Summary: Land use changes can significantly impact the magnitude and distribution of wind erosion. The cultivation of reclaimed lands reduces erodible particles and mitigates wind erosion. The extent of wind erosion in cultivated lands is influenced by cultivation years, as well as soil organic carbon and total nitrogen content. New cultivated lands are more susceptible to wind erosion compared to lands with medium cultivation years. Adopting conservative cultivation practices is crucial in protecting new cultivated lands from wind erosion hazards.

Summary: Dust emission is an important part of material circulation between lithosphere, atmosphere, and ocean systems. However, there have been few studies on dust emission in alpine areas, leading to large uncertainties in the global dust budget and challenges in controlling aeolian hazards in these regions. This study improves a dust emission model by considering air density as an important factor and accurately depicts the spatial and temporal distribution of dust emission in the Qinghai-Tibetan Plateau. The results provide valuable data for estimating the global dust budget and offer new insights into dust emission in environments with lower air temperature and lower air pressure.

Summary: The yardangs surrounding the Suoyang City ruins are wind-eroded landforms developed in an oasis used for agriculture in history. Research suggests that their formation possibly started in the mid-13th century and quickly evolved into desert land after being abandoned. Human activities and climate change both played significant roles in the process of desertification.

Summary: The highest sand dunes in the world are located in the Badain Jaran Desert in northwestern China, reaching heights of 200-300 meters and some even as high as 500 meters. Through sedimentary records and high-resolution optical dating, it was found that these giant transverse dunes migrated downwind over tens of thousands of years, with a migration rate of only a few centimeters per year, and are closely linked to global climate change. These findings highlight the significant role of global climate change in the formation and migration of megadunes during the last glacial cycle.

Summary: Human activity is a major cause of uncertainties in the global dust budget. The division of natural and anthropogenic dust sources is controversial, and their effects on dust emissions are difficult to distinguish. A model was used to simulate dust emission processes over the Qinghai-Tibetan Plateau, identifying natural and anthropogenic dust sources. The study found that land use changes had slightly larger effects on dust emissions compared to climatic fluctuations.

Summary: In recent decades, wind erosion has become a concern due to a declining trend in wind speed in northern China. The reclamation of grassland and sandy land into cropland has raised questions about the potential increase in wind erosion. This study used the Revised Wind Erosion Equation (RWEQ) to simulate the wind erosion in the Mu Us Sandy Land (MUSL) from 2000 to 2020 and analyzed the effects of different reclamation patterns on wind erosion. The results showed a decrease in wind erosion during the simulated period, and the WEM of croplands reclaimed by herdsmen was higher than that reclaimed by enterprises.
