Recharge sources, hydrochemical evolution, and health risks of groundwater and geothermal water in the Guangdong-Fujian coastal region, southeastern China

This study evaluates the hydrochemical characteristics, recharge sources, and health risks of groundwater in the Guangdong-Fujian coastal region, revealing that while most water is suitable for consumption, specific areas like Chagan Town and Zhongshan City pose significant non-carcinogenic risks due to manganese enrichment, highlighting the necessity of integrating multiple analytical methods for accurate water quality assessment.

Hydrodynamic drivers of microplastic degradation: SEM-Based surface roughness evidence from contrasting beaches

This study investigates microplastic contamination on two contrasting Moroccan beaches, revealing that while both are heavily polluted with artificial polymers, the beach with moderate wave activity (Sabadilla) exhibits higher surface roughness and more degraded particles compared to the calmer site (Quemado), suggesting that hydrodynamic conditions significantly influence plastic degradation and distribution.

Impact of climate change on water availability in the southern Peruvian Andes: a Study of the Colca River basin upstream of the Condoroma Dam

This study utilizes the GR4J hydrological model and CMIP6 climate projections to assess future water availability in the Colca River basin, revealing that while mean annual precipitation and temperature will rise significantly by 2100, the most critical hydrological impacts will be sharp increases in dry-season water availability accompanied by substantial uncertainty under high-emission scenarios.

Projected Impacts in Land Use/Cover Change on Carbon Storage and Sequestration in Zambia: 2020-2050

This study utilizes the PLUS model to project that while Zambia's land use changes will initially increase carbon sequestration and economic value through 2040, a subsequent decline in forest cover and carbon storage is expected by 2050, underscoring the urgent need for sustainable land management policies to mitigate these losses.

Regional Analysis of Urban Physical Factors Influencing Air Pollution: Evidence from Seoul’s Living Areas

This study analyzes how fine-scale urban physical factors influence air pollution distribution across Seoul's living areas, demonstrating that region-specific spatial relationships are better captured by geographically weighted regression than traditional models, thereby providing an evidence-based framework for targeted air-quality planning in high-density metropolitan contexts.

Characterization of organic carbon composition in coastal soils by mid-infrared attenuated total reflectance spectroscopy

This study demonstrates that mid-infrared attenuated total reflectance (MIR-ATR) spectroscopy is an effective field method for characterizing how different coastal vegetation types (mangrove, saltmarsh, and paperbark) influence the composition and degradation pathways of soil organic matter in coastal soils.

Territorial Governance Pathways for Implementing Nature-based Solutions: Enablers and Barriers of the Italian NATALIE Case Study

By combining a systematic literature review with empirical data from an Italian case study, this research identifies a critical asymmetry where academic literature emphasizes design-related governance factors while practitioners focus on intent-related conditions, ultimately concluding that the successful upscaling of Nature-based Solutions depends on translating project-level interventions into durable institutional frameworks through enhanced knowledge flows, policy coherence, participatory engagement, and trust.

A century of monthly rainfall in the Senegal River Basin (1895–2020): automated quality control, machine learning gap-filling, and the cost of network attrition

This study compiles a century-long, quality-controlled monthly rainfall archive for the Senegal River Basin and demonstrates that while machine learning effectively fills random data gaps, it is essential for correcting the significant wet bias introduced by terminal station attrition, which otherwise distorts the perceived magnitude of post-drought recovery.

Research Progress on Spontaneous Combustion Characteristics and Internal Influence Mechanism of Fractured Gas-bearing Coal Under Stress

This paper reviews the spontaneous combustion characteristics and internal mechanisms of fractured gas-bearing coal under stress, integrating macroscopic and microscopic analyses to elucidate the synergistic effects of stress and adsorbed gas, thereby addressing gaps in single-factor research and providing a theoretical basis for the collaborative prevention of compound gas and fire disasters in deep coal mining.
