Mapping Territorial Readiness for Green Hydrogen Deployment in Colombia: A GIS-Based Multicriteria Framework

This study develops a GIS-based multicriteria framework weighted by expert consultation to map Colombia's territorial readiness for green hydrogen deployment, revealing that optimal locations depend on a complex integration of economic, infrastructural, and institutional factors rather than renewable resource availability alone.

Integrating Indigenous Community-Developed Consequence Functions into Conventional Inundation Risk Modelling: An Aotearoa New Zealand Case Study

This paper presents a methodology for integrating iwi-led qualitative knowledge into the quantitative RiskScape modelling platform through a case study with Rangitāne o Wairau, demonstrating how codifying Indigenous consequence functions reveals the severe cultural and emotional impacts of tsunami scenarios that conventional economic models overlook.

Decadal debris records reveal legacy accumulation and emerging fishing-derived plastic inputs across the North Pacific

A decade-long analysis of North Pacific debris reveals that fishing gear, particularly from East Asian fleets, constitutes the majority of marine plastic pollution, with evidence suggesting that routine waste management practices rather than accidental loss are the primary drivers of this persistent accumulation.

Microplastics in Cattle and Dog Feces from Kathmandu Valley, Nepal

This study reveals widespread microplastic contamination in cattle and dog feces across the Kathmandu Valley, Nepal, demonstrating that microplastic abundance is significantly influenced by management systems and species, with polyolefins being the dominant polymers and fecal profiles reflecting complex environmental exposure beyond just dietary intake.

Co-occurrence and Ecological Risk of Microplastics and Polycyclic Aromatic Hydrocarbons in a Coastal Small Watershed: A Case Study of the Houxi River, Xiamen, China

This study provides the first integrated assessment of the Houxi River watershed, revealing a significant positive correlation between microplastics and polycyclic aromatic hydrocarbons driven by anthropogenic activities, which suggests synergistic accumulation mechanisms and emerging combined ecological risks in coastal small watersheds.

Material flows and operational carbon emissions in full- service tourist accommodation across comfort categories

This study presents the first peer-reviewed operational life-cycle carbon footprint of Irish tourist accommodation across three comfort categories, revealing that food and beverage procurement constitutes the largest emission source (40–58%) and reframing hospitality carbon management as a material-flow problem while providing robust, CSRD-compliant benchmarks and methodology.

Spatio-Temporal Analysis of the Pattern of Land use and Land Cover Changes among the Sub-Basins in the White Volta Basin

This study utilizes Landsat imagery and random forest analysis to quantify spatio-temporal land use and land cover changes in the White Volta Basin from 1995 to 2023, identifying agricultural expansion, urbanization, and mining as primary drivers of degradation that vary significantly across sub-basins, with Kulpawn being the most severely affected and Gambaga the least.

Heat as a Climate Justice Challenge:  Exposure and Adaptation Among Vulnerable Communities in Khulna and Dhaka

This study employs a climate justice framework and qualitative interviews in Dhaka and Khulna to reveal how extreme heat disproportionately harms vulnerable urban populations through gendered exposure and inadequate infrastructure, arguing that sustainable resilience requires shifting from reactive individual measures to participatory policies that address systemic governance and structural inequities.

GEDI spaceborne LiDAR reveals natural constraints and low- threshold human impacts on aboveground biomass across mainland China

This study utilizes GEDI spaceborne LiDAR data and an interpretable machine learning framework to reveal that aboveground biomass distribution across mainland China is governed by region-specific natural thresholds, such as soil pH and precipitation, as well as surprisingly sensitive negative impacts from even low levels of human modification.

Sacred forests as refuges for medium- and large-sized mammals under anthropogenic pressure: evidence from Debre Libanos Monastery Forest, Ethiopia

This study demonstrates that the Debre Libanos Monastery Forest in Ethiopia serves as a critical refuge for medium- and large-sized mammals, including the Vulnerable African leopard, despite significant anthropogenic threats like poaching and habitat encroachment, while highlighting the potential of combining habitat protection with local community participation and traditional religious stewardship for effective conservation.
