ALTYN Inversion: A MATLAB-Based 2D/2.5D Finite-Strike Gravity Inversion Framework with Box-Constrained IRLS Regularization

This paper introduces ALTYN, a transparent MATLAB-based 2D/2.5D gravity inversion framework utilizing box-constrained IRLS regularization and a projected Newton solver to generate geophysically admissible density models, demonstrating through synthetic and field tests that while the method effectively fits data and highlights shared structural features, it cannot uniquely reconstruct complex subsurface geometries due to inherent non-uniqueness.

Leveraging geospatial foundation model embeddings for local-scale landslide susceptibility mapping via positive-unlabeled learning

This study proposes a deployment-oriented workflow that integrates AlphaEarth foundation model embeddings with positive-unlabeled learning to overcome label and redundancy challenges, achieving highly selective local-scale landslide susceptibility mapping in Hong Kong by effectively fusing transferable geospatial representations with traditional physical features.

Integrated Multi-Frequency Water-Borne Ground-Penetrating Radar Imaging for Bathymetry and Sub-Bottom Stratigraphy characterization of the Kumaun Himalayan Lakes

This study demonstrates that integrated multi-frequency water-borne Ground Penetrating Radar (GPR) effectively maps bathymetry and sub-bottom stratigraphy in Himalayan lakes, enabling the objective selection of optimal sites for recovering undisturbed sediment cores essential for reconstructing Quaternary climate and geological history.

Diagnosis of the impact on wetland soils: Based on enzymatic parameters and heavy metals

This study demonstrates that the La Chimba Urban Wetland suffers from severe heavy metal contamination and a corresponding generalized reduction in key soil enzyme activities, indicating significant geochemical and biological degradation driven by chronic urban and industrial pollution compared to control and reference sites.

From Hazard Co-occurrence to Risk Mechanisms: Climate–Anthropogenic Interactions in Multi-Hazard Risk Formation

This study analyzes multi-hazard risk formation across three Indian regions to identify three distinct mechanisms—sequential propagation, interaction and connectivity, and cumulative stress—that explain how climate-related and anthropogenic influences interact to produce complex risks, thereby providing a mechanism-oriented framework for anticipatory risk assessment and governance.

Road typology is associated with street-tree diversity, structure and composition in a rapidly urbanizing Indian city

This study of Guwahati, India, reveals that road typology significantly influences the diversity, structure, and composition of urban street trees, with larger roads supporting higher species richness than highways, while highlighting the need for diversified planting and road-specific management strategies to enhance ecological resilience in rapidly urbanizing cities.

JUNIPER-Europe indicator-specific resource–environment nexus hotspots across six countries against a wider European reference

This paper introduces JUNIPER-Europe, a harmonized framework that utilizes 2000–2019 data to compare resource–environment nexus hotspots across six European countries and a wider EU reference, revealing distinct national profiles in water use, emissions, biodiversity risk, and quality of life to support integrated sustainability assessments.

SWAT-based evaluation of multi-decadal land use dynamics and hydrological response in the data-scarce Nambul River Watershed, Manipur

This study utilizes the SWAT model to evaluate the hydrological impacts of multi-decadal land use changes in the data-scarce Nambul River Watershed, revealing that despite significant urbanization and frequent flooding, the relationship between land cover alteration and runoff is complex and non-linear rather than directly proportional.

Roadless areas and the 30% protection target: contrasting national prospects in the Iberian Peninsula

This study demonstrates that incorporating roadless areas into conservation planning could help Spain and Portugal meet the EU's 30% land protection target by 2030, revealing that while Spain can achieve this goal by prioritizing just 2.7% of its roadless territory, Portugal requires additional measures beyond roadless land alone.
