Contamination of Soil and Groundwater with Toxic Heavy Metals near Lapite Dumpsite in Ibadan, Nigeria

This study demonstrates that the Lapite dumpsite in Ibadan, Nigeria, has significantly contaminated local soil and groundwater with toxic heavy metals through leaching, with metal concentrations in well water exceeding WHO guidelines and showing a marked increase over a ten-year period.

A Declining Longwave Cloud Radiative Effect over Iraq: Satellite-Based Climatology and Dynamical Attribution

This study utilizes multi-source satellite data to reveal a significant declining trend in spring longwave cloud radiative effect over Iraq from 2001 to 2024, attributing the spatial variability and temporal changes to orographic cloud enhancement, upper-level dynamical troughs, and local moisture sources while highlighting discrepancies with reanalysis models.

Hydrogeochemical characterization and groundwater quality assessment in a semi-arid carbonate aquifer system: Integration of GWQI and multivariate statistics (F'kirina region, Northeastern Algeria)

This study evaluates the groundwater quality in the F'kirina region of northeastern Algeria using physicochemical data from 2018–2021, revealing that most sampled boreholes are unsuitable for direct consumption due to elevated turbidity and hardness, as determined by a "poor" Groundwater Quality Index classification and Principal Component Analysis identifying mineralization and turbidity as dominant factors.

Climate change literacy linked to adaptation among Africa's most vulnerable

This study demonstrates that climate change literacy significantly drives adaptation among Africa's most vulnerable populations, particularly when combined with exposure to harmful climate trends, despite a concerning recent decline in literacy levels across the continent.

The inequities of human-elephant coexistence: Deterrent strategies and crop protection costs in Thailand

This study of Ruam Thai Village in Thailand reveals that the financial and social costs of human-elephant coexistence are unevenly distributed, trapping farmers in a "mitigation treadmill" where escalating defensive investments fail to prevent economic losses, thereby highlighting the urgent need for coordinated, community-led strategies to address these inequities.

Trace Elements Enrichment and Source Apportionment in Soils along an Urban-Rural Gradient in Xinxiang, China

This study investigates the spatial enrichment patterns and source apportionment of 12 trace elements in Xinxiang, China, revealing that while natural sources dominate overall soil composition, industrial activities and traffic are the primary anthropogenic drivers of cadmium and other heavy metal pollution along the urban-rural gradient.

Volcano-tectonic Seismicity at Villarrica Volcano: A Decade of Evidence (2014–2023) to Understand Its Internal Dynamics

This study analyzes a decade of volcano-tectonic seismicity at Villarrica Volcano to reveal distinct swarm evolution patterns and spatial stress variations that link shallow magmatic pressurization to delayed explosive activity, thereby providing a multiparametric framework for understanding the volcano's internal dynamics and improving hazard assessment.
