Summary: This study compares the spatio-temporal distribution and degree of aeolian desertification in the Moltsog and Ujimqin dune fields over the past 30 years. The results show that the degree and development rate of aeolian desertification in Ujimqin were generally higher than those in Moltsog, and the former had a high degree of fragmented aeolian desertification patches with an expanding range. Ujimqin is mainly driven by anthropogenic activities, while Moltsog is mainly affected by climatic factors.

Summary: Parabolic dunes are found in various climate and geographic zones worldwide. Understanding their development, activity, and link with climates is important for constraining past climate models and predicting future activity. This review analyzes the morphology and wind regimes of parabolic dunes globally, and explores the link between dune activity and climates over the past 20,000 years. It finds that dune migration is triggered by changes towards drier conditions and is currently influenced by human disturbances.

Summary: This study examines the desertification status and control needs in the Hotan desert oasis by analyzing and comparing vegetation index data. The results show that desertification mainly occurs in the transition zone between the oasis and the desert. By using vegetation index as a reference, appropriate measures can be taken to combat desertification at regional and global levels.

Summary: This study investigated the reaction processes of microbially induced magnesium carbonate precipitation (MIMP) with Sporosarcina pasteurii and its feasibility for controlling desertification in Northwest China. Results showed that excess Mg2+ slightly stimulated bacterial growth, and MIMP had a higher relative chemical conversion efficiency in Mg medium compared to Ca medium. MIMP has the potential to overcome traditional sand fixing methods and could be particularly useful for controlling desertification in areas with abundant Mg resources.

Summary: Salt lakes are important sources of dust, and efforts to reduce dust efflux often involve chemical stabilization with conventional additives. However, this can disrupt soil biogeochemical cycles. This research explores the use of ground rubber and colloidal nanosilica to create a thin, porous crust on calcareous lake sand, which shows promising strength and post-peak response.

Summary: Grazing exclusion is an important policy in China for recovering degraded grasslands, but its effects on sand dune ecosystems vary by topographic location. Long-term grazing exclusion leads to increased plant density, cover, species richness, soil organic carbon, and total nitrogen across different areas in sand dune systems.

Summary: This study used Salep biopolymer to stabilize dune sandy soil in the Kerman desert. The results showed that the highest dry unit weight was obtained with 5% replacement by weight of Salep biopolymer. The saturated CBR strength of the biopolymer-treated dune sand increased three times compared to untreated sand.

Summary: The patterns and driving factors of vegetation expansion during dune stabilization were examined in three coastal dunefields in Victoria, Australia. The trajectory of vegetation expansion was found to be determined by dunefield topography, with colonization occurring at different parts of the dunefield. Pre-existing vegetation played a critical role in dune re-vegetation and subsequent expansion, as it provided seeds and changed the micro-climates. This research provides important insights into vegetation expansion during dune stabilization and can help identify management intervention opportunities.

Summary: The study comprehensively analyzed the dynamic changes, material sources, dust activity history, and influencing factors of sand dunes in the Hexi Corridor. The results showed that climate is the primary influencing factor of dune landform changes and the source materials of sand dunes mainly come from alluvial/proluvial and palaeo-fluvial sediments. The movement direction of sand dunes is controlled by the regional-scale wind system. The warming and humidification of the Hexi climate is a synchronous response to global warming and the strengthening of the Asian Summer Monsoon, and it is also the main reason for the reduction of dust storms in the study area, while desertification in oasis areas is caused by groundwater fluctuation affected by human activities.

Summary: The detrimental effects of sand storms, such as on agriculture, human health, transportation network, and infrastructures, are considered a global challenge. This study introduces and compares the performance of calcium formate-bacteria and calcium acetate-bacteria compositions for non-ureolytic microbially induced carbonate precipitation. The results show that the calcium formate-based compositions performed better in producing CaCO3, and Bacillus subtilis produced more CaCO3 than Bacillus amyloliquefaciens. All compositions significantly reduced wind erosion.

Summary: This study investigates the variations and influencing factors of Center Pivot Irrigation (CPI) farmlands in the southeastern part of the Mu Us dune field in China. The results show an increasing trend in the number and area of CPI farmland units, with topography, temperature, and geological substratum identified as the major natural factors driving the development of CPI farmlands. The study suggests strict management of CPI farmland through effective long-term planning and land-use policies to achieve sustainable development of agriculture and ecological significance in dune field areas.

Summary: This study evaluated the effect of alternative filtering materials and bed aeration on the retention of nutrients and fecal bacteria in woodchip bedded stand-off pads for cows. The results showed that the alternative biofilters were more efficient in removing COD, SS, TN, and NO3-N, while conventional biofilters were more efficient for PO4-P removal. Aeration did not have a significant effect under the tested temperature conditions.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: In this study, an electron beam excitation multi-wavelength ultraviolet (EBE-MW-UV) system was established and found to have significantly higher microbial inactivation effects compared to single-wavelength UV-LEDs in water. Mechanism analysis revealed that EBE-MW-UV damaged microbial DNA and proteins, and generated additional reactive oxygen species, leading to microbial inactivation.

Summary: This study focuses on the development of an air-lift bio-electrochemical reactor (ALBER) with a continuous feeding regime to enhance nitrogen removal from synthetic wastewater. The effect of temperature, hydraulic retention time (HRT), N -NH+4 /TN ratio, and current density on the reactor performance was investigated, and the ALBER achieved a maximum TN removal of 73%. The results suggest that the ALBER has potential for treating industrial wastewater at low temperatures.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
