Between extraction and protection: Public support for natural resource regulation and environmental governance across Africa, a continental analysis with West Africa as a case study
Published: 2026-04-24
Subjects: Environmental Studies
Natural resource extraction is central to development strategies across Africa, yet it generates persistent conflicts over environmental costs, benefit distribution, and governance legitimacy. Public attitudes toward this trade-off have remained largely unmeasured at the continental scale. This paper provides the first cross-national quantitative analysis of citizen preferences for environmental [...]
Slope-dependent riverbed strengthening and the evolution of the threshold for motion in gravel-bed rivers
Published: 2026-03-10
Subjects: Earth Sciences, Geomorphology, Hydrology
The threshold for motion exerts a fundamental control on sediment transport, channel morphology, and fluvial erosion. While channel slope and flow history are known to influence entrainment thresholds in gravel-bed rivers, their interaction has not been explored. We investigate how channel slope modulates riverbed strengthening during low-flow periods. Flume experiments were conducted across [...]
Theory and Conditions for AI-Based Inversion Paradigm of Geophysical Parameters Using Energy Balance
Published: 2024-12-08
Subjects: Engineering, Physical Sciences and Mathematics
To construct a universal artificial intelligence (AI) model for geophysical parameter inversion, this study proposes a new remote sensing parameter inversion paradigm theory by changing cognition to unify physical, statistical, and AI methods. In the AI era, deep learning serves as a macro-micro cognitive bridge, transforming remote sensing from classical physics to a quantum remote sensing [...]
Automating glacier facies classification: pan-European dataset and deep learning baseline
Published: 2026-01-27
Subjects: Artificial Intelligence and Robotics, Glaciology
Glacier facies play a critical role in understanding the mass balance of glaciers, offering insights into accumulation and melting processes. Large-scale mapping of glacier facies from satellite data is therefore essential for monitoring glacier response to climate change and informing climate policies. In this study, we present the largest glacier facies dataset ever compiled for Europe, [...]
Microphysical Evolution of Precipitation During Convective Storm Life-Cycles and Implications for Radar QPE: Combined Radar–Disdrometer Observations from Kolkata, Eastern India
Published: 2026-04-25
Subjects: Earth Sciences, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics
Through dedicated observations with a Joss–Waldvogel disdrometer at Dumdum (22.65°N, 88.43°E) and the S-band Doppler Weather Radar (DWR) (22.57°N, 88.35°E) over Kolkata, this study provides in-depth analysis of drop size distribution (DSD) evolution over each stage from initiation to decay of contrasting convective storms over Kolkata, eastern India due to its complicated terrain in monsoon [...]
Characterizing the interrelationships of commonly used water measures
Published: 2026-03-18
Subjects: Public Health
There are numerous commonly used measures of household water access that capture various dimensions of the household water experience, but it is unclear if individual variables are complementary, redundant, or uniquely informative. We characterized how measures of household water access are statistically and conceptually interrelated. Using data collected from 861 households in Beira, Mozambique [...]
Do Less Predictable Tropical Cyclones Induce Larger Damages?
Published: 2026-03-17
Subjects: Atmospheric Sciences, Hydrology, Meteorology, Statistical Models
Tropical cyclones (TCs) cause substantial disaster losses worldwide. Forecast skill for TC track and intensity has been improved by enhanced observations, high-resolution numerical models, advanced data assimilation methods, and applications of machine-learning methods. Yet these improvements have not consistently translated into reduced losses, in part because disaster outcomes depend on many [...]
WetlandMapper: A Python package for automatic wetland mapping, dynamics classification, and cover-type characterisation from multispectral time-series data

Investigating the application of LLMs to invertebrate palaeontology through the development of automated taxonomy assistants for brachiopod identification
Published: 2026-03-19
Subjects: Earth Sciences, Physical Sciences and Mathematics
Taxonomic identification is a central practice in palaeontology, underpinning biostratigraphic correlations, palaeobiogeographic reconstructions, and analyses of macroevolutionary patterns. Despite its importance, taxonomy depends on a limited number of specialists and on the synthesis of extensive descriptive literature that is often difficult to access. Recent developments in artificial [...]
Polymineralic synneusis in silicic magmas revealed by megacryst-inclusion orientation relationships
Published: 2026-03-19
Subjects: Earth Sciences
Crystal aggregation via synneusis is well-documented in many common igneous minerals, such as quartz and olivine. Synneusis is typically described as a monomineralic process whereby two crystals of the same mineral adhere in specific low-energy orientation relationships. In contrast, unlike minerals are generally assumed to be antipathetic. Nonetheless, the occurrence of polymineralic synneusis [...]
Wet and Dry Hydrological Conditions Reduce Chlorophyll-a at River-Lake Interfaces
Published: 2026-05-10
Subjects: Climate, Environmental Monitoring, Fresh Water Studies, Longitudinal Data Analysis and Time Series, Water Resource Management
Hydrological variation is intensifying under climate change, yet its net effects on lake water quality remain uncertain. Wet and dry hydrological conditions are commonly assumed to exacerbate eutrophication by increasing nutrient inputs during wet conditions or concentrating nutrients during dry conditions. However, these events can also activate counteracting processes—such as dilution, or [...]
Remote Forcing of Internal Waves in Regional Ocean Models
Published: 2026-03-10
Subjects: Engineering, Physical Sciences and Mathematics
Regional oceanic general circulation models with nested grids are an essential approach to allow the use of higher grid resolutions. High resolution is required for the study of smaller scale processes, such as submesoscale currents and the internal wave field, in particular the baroclinic tide. Limits of available computing power determine the size of the computational grid, setting the [...]
Filling the monitoring gap: Aquatic ecosystem metabolism as a cost-effective, scalable tool for assessing marine carbon dioxide removal
Published: 2026-02-18
Subjects: Earth Sciences, Environmental Sciences, Oceanography and Atmospheric Sciences and Meteorology
Marine carbon dioxide removal (mCDR) is an emerging climate mitigation solution increasingly recognized as necessary to supplement greenhouse gas emission reductions. Various mCDR methods, from biotic to abiotic measures, are being piloted, fueled by enthusiasm from governments and the private sector. As companies start to sell carbon credits, standards for monitoring, reporting, and verification [...]
Prediction of Land Surface Temperature under overcast skies using Data Fusion and Deep Learning approach
Published: 2026-04-12
Subjects: Geographic Information Sciences, Remote Sensing, Spatial Science
Land Surface Temperature (Ts) is an essential input to drive surface energy balance for modelling terrestrial ecosystem processes. It serves as a vital indicator of drought, global change, urban heat islands, public health, and most importantly to understand monsoonal water stress signatures. Thermal InfraRed (TIR) remote sensing is the only source to retrieve Ts. Retrieval of Ts in the tropics [...]
