This study utilizes geoinformatic techniques and Landsat imagery from 1994 to 2018 to demonstrate that rapid urbanization in Ghaziabad district has significantly increased built-up areas and water bodies while causing substantial declines in vegetation, barren land, and forest cover, leading to a measurable deterioration in soil quality.
This study introduces a layered vulnerability framework that decomposes climate–health risk in Kenya (1987–2023) into structural, buffering, and amplification components, demonstrating that while baseline susceptibility explains most variation, system capacity and amplification pathways are critical independent modifiers of realized impacts.
This study employs a dynamic material flow analysis to forecast future demand and circularity potentials for steel, concrete, and asphalt in Dutch macro-infrastructure, revealing that while end-of-life material recovery could theoretically satisfy the majority of future demand, technological and regulatory constraints currently limit closed-loop circularity to significantly lower levels, necessitating targeted policies to reduce virgin material use and achieve net-zero targets.
This study analyzes the water quality characteristics and pollution sources of the Binan River Basin in Bishan District using a PMF model, revealing that nitrogen pollution is the primary contaminant, water quality deteriorates during the dry season, and agricultural runoff is the dominant source, thereby providing a scientific basis for seasonal and source-specific watershed management strategies.
A global analysis of phytane and pristane isotopes reveals that phytoplankton have consistently dominated marine organic matter production and burial over the past 500 million years, with observed isotopic variability driven by environmental CO₂ levels rather than evolutionary changes in biological functionality.
Using ambient-noise tomography on a temporary seismometer network, researchers imaged a shallow, pressurized magma storage zone and an overlying hydrothermal conduit beneath Mt. Aso's Nakadake crater, revealing how these structures facilitate fluid transport and generate volcanic tremors.
Although targeted additions to the Arctic-boreal carbon flux tower network between 2022 and 2024 significantly improved regional representativeness for most measurement categories, substantial gaps persist, particularly for year-round methane monitoring and in Russia.
This study reveals that forced displacement and prolonged exile have caused a severe erosion and fragmentation of Local Ecological Knowledge regarding wild food plants and herbal teas among Afghan returnees, transforming much of this heritage into "inert knowledge" and highlighting the urgent need for biocultural policies to support its revitalization.
This study reveals that water sources in Nigeria's Rafin Gora gold mining community contain elevated levels of naturally occurring radionuclides (226Ra, 228Ra, and 40K) that significantly exceed WHO guidelines, posing serious chronic radiological health risks including high annual effective doses and cancer risks that necessitate immediate regulatory intervention and water treatment.
This study assessed the acute toxicity of 44 individual fungicides and their binary mixtures on the green alga *Raphidocelis subcapitata*, identifying additive, antagonistic, and synergistic interactions to establish critical hazard parameters and benchmark values for mitigating aquatic ecological risks.
