An Upward-Continuation-Based Framework for Subsurface Structural Reconstruction from Gravity Anomalies

This study introduces the UCRD–NFG framework, a model-independent method that combines upward-continuation-based decomposition with the Normalized Full Gradient technique to efficiently reconstruct subsurface structural geometry and estimate depths directly from Bouguer gravity anomalies without requiring inversion or prior geological information.

Comparative Analysis of Urban Sprawl Dynamics in the Growing Cities of Konya and Bukavu

This study employs a qualitative comparative analysis of Konya and Bukavu to reveal how formal planning in the former fosters structured yet car-dependent expansion, while informal dynamics in the latter drive unregulated growth, ultimately demonstrating that effective urban sprawl management requires context-specific policies rather than assuming all Global South cities lack governance capacity.

A Coupled Hydrochemical-Geophysical approach for assessing Seawater intrusion in coastal aquifer: Gir-Somnath, Gujarat, India

This study integrates hydrochemical analysis and Electrical Resistivity Tomography to demonstrate that seawater intrusion in the Gir-Somnath coastal aquifer is primarily driven by excessive groundwater extraction and pumping-induced upconing through permeable limestone, resulting in significant salinization that varies seasonally with recharge and extraction rates.

Late-season flow recovery and trough-aligned subsidence reveal coexisting subglacial drainage components beneath the western Greenland Ice Sheet

By applying Sentinel-1 SAR interferometry to the western Greenland Ice Sheet, this study reveals that late-season ice flow recovery and trough-aligned subsidence are driven by coexisting weakly connected and well-connected subglacial drainage components, respectively, highlighting the critical role of bed troughs in storing and releasing meltwater well after surface melting ceases.

Arctic-wide freshwater outburst from the Baltic Ice Lake contributed to the onset of Preboreal cooling

This study uses high-resolution sedimentary records from the southwestern Barents Sea to demonstrate that a major freshwater outburst from the Baltic Ice Lake around 11.5 to 11 thousand years ago triggered widespread Arctic cooling, sea-ice expansion, and ocean circulation changes during the onset of the Preboreal period.

Mining Hazardous Waste, Acid Mine Drainage, and Their Combined Environmental and Social Impacts in the Democratic Republic of Congo: A Systematic Review

This systematic review synthesizes evidence from 48 sources to demonstrate that decades of industrial and artisanal mining in the DRC's Katanga region have generated severe acid mine drainage and hazardous waste, causing metal concentrations in water and soil to far exceed WHO guidelines while exposing vulnerable communities, particularly women and children, to significant health risks amidst a critical gap between environmental regulations and enforcement.

Machine Learning Prediction of Early-Season Wildfire Risk in Ghana’s Guinea Savannah Using Multi-Source Data and CMIP6 Climate Scenarios

This study develops and evaluates a high-performing machine learning prototype for predicting early-season wildfire risk in Ghana's Guinea Savannah by integrating multi-source environmental and human data, demonstrating superior accuracy over traditional indices while offering illustrative future projections under CMIP6 climate scenarios with the caveat that it remains a research tool rather than a fully validated operational warning system.
