Hydroclimatic Variability and Drought Characterisation in Northern Togo, 1981-2025

This study reveals that while rainfall trends in northern Togo (1981–2025) remain statistically insignificant, a significant warming trend since the early 2000s has intensified evapotranspiration and moisture deficits, necessitating temperature-sensitive drought indices for effective monitoring and resource management in this climate-vulnerable region.

Physical Sandbox Simulation of Groundwater Contaminant Transport Using the Resistivity Method and Its Application

This study validates the resistivity method as an effective, non-destructive tool for tracking inorganic groundwater contamination by establishing quantitative relationships between electrical resistivity, flow velocity, and concentration through sandbox simulations and confirming its accuracy in monitoring landfill leachate migration.

Embedding sustainability in research-intensive organisations: A transferable governance framework from a biomedical research institute

This study presents a transferable institutional governance framework for embedding sustainability in research-intensive organizations, demonstrating through a longitudinal case study of the University of Liverpool's ISMIB that integrating sustainability into governance structures, operations, and culture—rather than relying on isolated technical fixes—effectively drives organizational transformation and environmental responsibility.

Nephelometer-based air sensor networks systematically underestimate PM2.5 in dust-influenced West Africa

A multi-year study of air sensor networks in Ghana reveals that standard nephelometer-based sensors systematically underestimate PM2.5 and PM10 concentrations by significant margins during dusty Harmattan conditions, highlighting critical limitations in relying solely on optical sensors for air quality monitoring in dust-influenced regions like West Africa.

Spatially concentrated heat emissions from data centers lead to localized urban warming and heat exposure

This study integrates facility-level data with urban climate modeling to reveal that concentrated heat emissions from data centers in California create localized warming hotspots, significantly increasing land surface and air temperatures, particularly at night and in densely populated areas like Los Angeles, thereby highlighting the need for informed urban planning and facility siting.

Contribution of matrix hydraulic conductivity to groundwater flow in highly fractured high-porosity rock with low swelling properties and minimal fracture infill

Through in situ hydraulic testing and stochastic inverse analysis at the Horonobe Underground Research Laboratory, this study demonstrates that in highly fractured, high-porosity mudstones with low swelling properties, both high matrix hydraulic conductivity and fractures significantly contribute to groundwater flow regardless of fracture density.
