Summary: Enhanced rock weathering (ERW) is considered a promising negative emissions technology in croplands. However, the carbon sequestration potential and sensitivity of ERW to climate conditions need further understanding. Through modeling and experiments, ERW on approximately 1,000 agricultural sites globally is simulated. The application of 10 tons of basalt dust per hectare on these sites can sequester 64 gigatons of CO2 over a 75-year period, and extrapolated to all agricultural land, ERW can sequester 217 gigatons of CO2. However, optimization of application strategies is necessary for cost effectiveness.

Summary: This study investigates the effects of the discharge from an intact rock glacier on a high-elevation stream in the NW Italian Alps. Despite draining only 39% of the watershed area, the rock glacier contributes a large amount of discharge to the stream, particularly in late summer and early autumn. Ice melt is not a significant component of the discharge due to the insulating debris mantle. The sedimentological characteristics and internal hydrological system of the rock glacier play a major role in storing and transmitting groundwater.

Summary: The presence and characteristics of rock fragments (RFs) have significant impacts on soil hydrological processes (SHPs). The position, content, coverage area, mulching thickness, and size of RFs have different effects on SHPs. Completely inserted RFs improve saturated hydraulic conductivity and runoff rate, while reducing evaporation rate, infiltration rate, and soil water content. RFs resting on the surface and partially covering soil surface improve infiltration rate, but reduce evaporation rate, surface runoff rate, and soil loss rate. Completely mulched RFs reduce evaporation rate and infiltration rate, while improving soil water content and storage. Partially embedded RFs increase surface runoff rate, soil loss rate, and soil water content, but reduce infiltration rate.

Summary: The presence of pyrite-bearing rocks promotes naturally occurring acid rock drainage (ARD) in permafrost environments. The interaction between solid ice, meltwater, and pyrite causes the formation of sulfuric acid and the mobilization of toxic elements. Field and laboratory studies showed that intact rock glaciers act as efficient chemical reactors, leading to high concentrations of toxic elements in high-alpine streams. The water quality downstream of intact rock glaciers with pyrite-bearing rocks should be carefully monitored to assess the future environmental hazard.

Summary: This study examines the changes in human well-being in China from 1995 to 2017 by revising the genuine progress indicator (GPI). The results show that the per capita GPI of China increased with an annual growth rate of 12.43%. The increase in well-being was mainly driven by economic growth, but it was most sensitive to social factors. Factors such as income inequality and the cost of lost leisure time had negative impacts, while personal consumption expenditures and other factors accelerated the rise in the GPI. Overall, policy adjustments counteracted negative impacts and led to a significant increase in the per capita GPI.

Summary: Soil erosion is a global soil degradation problem that endangers land, freshwater, and oceans. Rainfall erosivity has led to an increase in soil erosion rate worldwide, while vegetation restoration serves as a protective measure against soil erosion. Therefore, studying the impact of precipitation and vegetation on the spatial distribution of soil erosion is crucial for understanding the erosion mechanism. Based on the RUSLE model, a global soil erosion dataset from 2000 to 2015 (0.25 degrees x 0.25 degrees) was created to assess the extent of global soil erosion. The data revealed that soil erosion was on the rise in 70.80% of the study area, with precipitation being the predominant factor. Spatially, erosion was mainly concentrated in Asia and North America, with Asia experiencing a decreasing trend in erosion during the study period. Results also showed that erosion primarily occurred in the temperate zone, accounting for 39.97% of the area. Precipitation and vegetation significantly increased in 24.43% and 16.74% of the regions, respectively. However, in 29.12% and 53.81% of the regions, precipitation and vegetation had a negative impact on erosion. These findings contribute to a deeper understanding of the erosion mechanism.

Summary: China has the largest distribution of carbonate karst in the world, with the southwest region centered in Guizhou being a critical ecological security barrier. Scientific diagnosis of the health and sustainability of karst ecosystems is essential for ecological restoration and sustainable development. In this paper, the evolution and development of karst landforms are summarized, along with five aspects related to the calculation of weathering and soil formation rate, diagnosis of soil water, evaluation of soil and water loss, interpretation and evolution of rocky desertification, and measurement of ecosystem services. The methods and models for diagnosing the health of karst ecosystems must be improved and innovated to accurately depict the response process of karst ecosystems to climate change and human activities.

Summary: This study investigated the migration regulation of Cd during soil formation and erosion in karst areas. The results demonstrate that soil Cd concentration and bioavailability are both significantly higher in alluvium compared with those in eluvium. The Cd isotopic fingerprint revealed that the active Cd in the alluvium of the study profile was probably derived from the corrosion of carbonate rocks rather than by eluviation of the eluvium. The corrosion of carbonate rocks is a substantial natural Cd source and poses significant potential risks to the ecological environment.

Summary: Karst ecosystems are crucial for billions of people, and accurately diagnosing and evaluating their health is necessary for socioeconomic development. However, current evaluation methods have limitations, particularly in considering the impact of soil formation rate on ecosystem health. A new index was established to represent the actual health status of karst ecosystems, revealing that the soil formation rate threatens the health of 28% of global karst ecosystems, covering an area of 594 km2. A dataset of karst ecosystem health index values from 2000 to 2014 was created, showing that 75.91% of the areas were unhealthy. This study emphasizes the contribution of soil formation rate to karst ecosystem health and provides a new method for accurate evaluation, enhancing future research and management.
