Environmental factors—including parent material, climate, vegetation, topography, soil, and human activities—inevitably drive SOC variations. However, vegetation and climate are likely the two most influential factors impacting SOC variations. To test this hypothesis, we conducted experiments using 31 environmental variables combined with the recursive feature elimination (RFE) algorithm. These experiments showed that RFE retained all vegetation variables [Land cover types (LCT), normalized difference vegetation index (NDVI), leaf area index (LAI), and gross primary productivity (GPP)] as well as two climate variables [Moisture index (MI) and drought index (DI)], supporting our hypothesis. We then analyzed the relationship between SOC and the retained vegetation and climate variables using random forest (RF), Shapley additive explanations (SHAP), and GeoDetector models to quantify the independent and interactive drivers of SOC distribution and to identify the optimal conditions for SOC accumulation. The RF model explained 68% and 42% of the spatial variability in SOC at depths of 0–1 m and 1–2 m, respectively, with SOC stocks higher in the southeast and lower in the northwest. Additionally, SOC stock at 0–1 m was significantly higher (<i>p</i> &lt; 0.05) than at 1–2 m in alpine meadows, alpine wet meadows, and swamp meadows. Conversely, SOC stock in alpine deserts, steppe meadows, and barren land did not differ significantly between the two depths (<i>p</i> &gt; 0.05). Spearman correlation coefficients results indicated that NDVI, LAI, GPP, and MI had highly significant positive correlations with SOC (<i>p</i> &lt; 0.01), whereas DI had a highly significant negative correlation with SOC (<i>p</i> &lt; 0.01). SHAP analysis revealed environmental thresholds for SOC variations, with notable shifts at NDVI (0.40), LAI (7), GPP (250 g C m⁻² year⁻¹), MI (0.40), and DI (0.50). The spatial distribution of these thresholds aligns with the 400 mm equivalent precipitation line. Additionally, GeoDetector results emphasized that interactions between climate and vegetation factors enhance the explanatory power of individual variables on SOC variations. The swamp meadow type, with an NDVI range of 0.73–0.84, LAI range of 11.06–15.94, and MI range of 0.46–0.56, was identified as the most favorable environment for SOC accumulation. These findings are essential for balancing vegetation and climate conditions to sustain SOC levels and mitigate climate change-driven carbon release.</p></div>","PeriodicalId":542,"journal":{"name":"Environmental Earth Sciences","volume":"84 12","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a simple and reliable method to measure the sediment accretion rate remains limited. In this study, sediment profiles in the restored wetlands in the Yellow River Delta (YRD) were collected, and a change point technique (CPT) was proposed to determine the recently accreted sediment (RAS). The variables including TOC, TN, TP, and δ¹³C, which were related to the accumulation of soil organic matter, were more suitable for calculating the depth of the RAS in the restored wetlands. The sediment accretion rate was calculated with the RAS in conjunction with the operational years of the wetland. The results showed that the average sediment, TOC, TN, and TP accretion rates were 0.49 ± 0.08 cm a⁻¹, 138 ± 24 g m⁻² a⁻¹, 15.8 ± 2.6 g m⁻² a⁻¹, and 2.8 ± 0.4 g m⁻² a⁻¹, respectively, for the restored wetlands since 2006 (RW2006). For the restored wetlands since 2002 (RW2002), the sediment, TOC, TN, and TP accretion rates were 0.68 ± 0.05 cm a⁻¹, 268 ± 69 g m⁻² a⁻¹, 25.3 ± 5.7 g m⁻² a⁻¹, and 5.5 ± 0.8 g m⁻² a⁻¹, respectively. These data indicated a significantly higher sediment and nutrient accretion rates in the older restored wetlands. This fact maybe caused by the longer wetland restoration significantly increased sediment organic matter content and sediment accumulation through plant litter decomposition and root stabilization. In conclusion, the CPT technique is a data-driven and high-resolution method, eliminating reliance on stable depositional environments or physical tracers. Therefore, the CPT can be accurately used to determine the sediment accretion rate in restored or constructed wetlands. In future, the restored wetlands will be important for the sediment and nutrient storage in YRD.</p></div>","PeriodicalId":542,"journal":{"name":"Environmental Earth Sciences","volume":"84 12","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, the study examines how the addition of 15% Magnesium Oxide (MgO) to bentonite-modified soil impacts geotechnical properties such as plasticity index, liquid limit, optimum moisture content, permeability, swelling, swelling pressure, volumetric shrinkage, and desiccation cracking. In addition, the objective of this paper was to shed light on the mechanisms that were responsible for the change in the hydro-mechanical behavior of the clay material that had been treated with MgO by conducting scanning electron microscope (SEM), energy dispersive spectroscopy (EDS) and Fourier transform infrared spectroscopy (FTIR) testing. The results indicate that MgO treatment significantly reduces the free swell, hydraulic conductivity, plasticity index, liquid limit, optimum moisture content, volumetric shrinkage and desiccation cracking, thus enhancing the material's stability and integrity under environmental stresses. Based on these findings, the study recommends using MgO-treated expansive soils as a more reliable alternative to traditional bentonite liners, offering better long-term performance and reduced risk of failure in landfill applications.</p></div>","PeriodicalId":542,"journal":{"name":"Environmental Earth Sciences","volume":"84 12","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These changes are characterized by altered topography, reduced glacier-covered areas, and variable climatic conditions across different regions, resulting in enhanced melt rates and increased vulnerability to glacial hazards. Understanding these distinctive characteristics is crucial for predicting future water resource availability and mitigating climate-induced hazards. In the present study, glacier mass balance was computed by analyzing temporal elevation changes across the entire Karakoram-Himalayan Range from 2000 to 2023. This analysis utilized the Shuttle Radar Topography Mission (SRTM) and Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Digital Elevation Model (DEM) datasets from two distinct periods to accurately assess changes in glacier elevation and mass. The study revealed a trend of positive elevation change in the Karakoram region, along with an uneven spatial distribution of elevation changes when moving from Western to Eastern Himalayan glaciers. The Karakoram Range exhibited average mass balance rates of -0.04 ± 0.09 m.w.e./yr, while the Western Himalayas recorded change rates of approximately -0.41 ± 0.24 m.w.e./yr. In contrast, the Central and Eastern Himalayan sectors demonstrated rates of -0.39 ± 0.21 m.w.e./yr and -0.50 ± 0.31 m.w.e./yr, respectively. The results indicate accelerating mass loss in the Western, Central, and Eastern Himalayas, while the Karakoram sector remains relatively stable. Notably, the increasing rate of mass loss in the Eastern Himalayas is particularly alarming. However, mass balance measurements in this study relied upon surface elevation changes and may not accurately reflect internal ice dynamics or basal melting.</p></div>","PeriodicalId":542,"journal":{"name":"Environmental Earth Sciences","volume":"84 12","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dominance of Na⁺, Ca²⁺, and HCO₃⁻ across all water sources reflects active silicate (SW) and carbonate (CW) weathering. Discharge-weighted SW rates peak during monsoon in IS (6.77 t km^− 2 yr^− 1) and the river (8.17 t km^− 2 yr^− 1), while CW dominates IS in pre-monsoon (2.89 t km^− 2 yr^− 1 vs. river: 0.23 t km^− 2 yr^− 1). Silicate weathering drives CO₂ consumption in IS (1.65 × 10⁵ mol km^− 2 yr^− 1) and the river (2.01 × 10⁵ mol km^− 2 yr^− 1), with CW contributing 0.40 × 10⁵ and 0.15 × 10⁵ mol km^− 2 yr^− 1, respectively. Forward geochemical modeling identifies SW as the primary solute source in IS (40%) and GW (34.3%), whereas atmospheric deposition dominates river solutes (46%), followed by SW (41.6%). Carbonate dissolution contributes 23% to GW and 16.2% to IS. Hydrologically, IS exhibit chemostatic behaviour (stable solute concentrations across discharge), contrasting with the river’s chemodynamic responses (seasonal dilution/enrichment linked to monsoon-driven runoff). These results underscore the role of lateritic regolith in buffering IS hydrochemistry and highlight monsoon-driven surface processes controlling river solute variability. By bridging weathering fluxes, CO₂ budgets, and hydrological controls, this work provides critical implications for sustainable water management and climate resilience in tropical critical zones.</p></div>","PeriodicalId":542,"journal":{"name":"Environmental Earth Sciences","volume":"84 12","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After 360 days of aging at 90 °C and 300 days at 150 °C, the maximum swelling pressure declined by 47% and 50%, respectively. Microstructural analysis revealed that thermal aging modified the pore structure of GMZ bentonite, reducing inter-aggregate pores while increasing the proportions of intra-aggregate and extremely small pores.

Gujarat, located in the dry and semi-arid region of India, is particularly vulnerable to these processes due to its dependence on monsoon precipitation, which is characterized by significant variability. This study examines rainfall data from the India Meteorological Department for the period 2000 to 2020 and satellite-derived Normalized Difference Vegetation Index (NDVI) values for 2001, 2011, and 2021 to assess spatial and temporal trends in desertification across selected districts. The analysis indicates an overall increasing trend in monsoonal rainfall during the two decades, but this increase is unevenly distributed, with certain districts experiencing more pronounced variability. Remote sensing data reveal a complex pattern of vegetation dynamics. Districts like Porbandar and Bharuch show improvements in NDVI values, suggesting enhanced vegetation cover and potential recovery from land degradation. Conversely, Vadodara exhibits declining NDVI trends, highlighting escalating risks of desertification, likely driven by intensified anthropogenic pressures such as industrialization and deforestation. This research highlights the critical interplay between climatic factors and land use changes in shaping regional ecological health. The findings underscore the need for proactive and region-specific land management strategies to mitigate desertification.

This study investigates groundwater flow and contaminant dynamics in an altered vadose zone and fractured rock environment at a quarry situated 20 km east of Pretoria, South Africa. The primary objective is to develop effective monitoring strategies for groundwater protection post-mine closure. The heterogeneous geological structures, including a network of fractures and a diabase sill, generate distinct water types and flow dynamics, with active groundwater circulation despite seasonal fluctuations. Field investigations and tracer analyses revealed seasonal variations in transport parameters. Blasting activities modified fracture characteristics, creating new pathways and increasing connectivity between fracture networks, complicating contaminant migration. Tracer tests analysed with the MDMi and MDP-2RNE analytical models identified variations in Péclet numbers and mean transit times, with higher transport velocities and lower retardation factors during the wet season. The MDMi model was more sensitive to fracture connectivity changes, while the MDP-2RNE model highlighted seasonal differences in flow velocities and dispersion. These findings highlight the challenges of parameterisation and the necessity for seasonal calibration in modelling contaminant transport.
