Quantifying damage and vulnerability for volcanic hazards
Published: 2025-04-30
Subjects: Volcanology
Reducing volcanic risk requires a comprehensive understanding of the potential impacts of volcanic hazards on various community elements, assets and critical infrastructure. This chapter considers systematic approaches to characterizing the interaction (impacts) between volcanic hazards and assets (broadly defined). Damage states provide a description of volcanic hazard impacts and can be used in [...]
Pathways to Carbon Neutrality: A Review of CO2 Reduction Strategies
Published: 2025-04-29
Subjects: Engineering
The global climate crisis, driven largely by the escalating levels of carbon dioxide (CO2) emissions, has prompted an urgent need for effective mitigation strategies. CO2, the predominant greenhouse gas, is primarily released through fossil fuel combustion, industrial processes, and deforestation. Its continuous accumulation in the atmosphere has led to severe climate disruptions, including [...]
Temporal convolutional networks for subsidence prediction in snowy regions
Published: 2025-04-29
Subjects: Environmental Engineering, Hydrology, Longitudinal Data Analysis and Time Series, Sustainability
This paper introduces a model based on a temporal convolutional network (TCN) for predicting future land subsidence caused by groundwater pumping for snow melting. Developed using historical snowfall and cumulative subsidence data from Joetsu City, Japan, the model demonstrates satisfactory performance in predicting observed land subsidence. The results suggest that TCNs are effective for [...]
Evolution of the Climate as an Attributable Complex System with Main Cause
Published: 2025-04-29
Subjects: Atmospheric Sciences, Climate
Attributable complex systems can be classified into two categories: those with a main cause and those without. The climate is an attributable complex system with a main cause, where CO2 concentration serves as the primary fingerprint. The essential dynamics of climate change can be effectively captured through the representation of CO2 concentration. In this study, we analyze global warming in [...]
Natural forests of the world - a 2020 baseline for deforestation and degradation monitoring
Published: 2025-04-29
Subjects: Artificial Intelligence and Robotics, Computer Sciences, Earth Sciences, Environmental Sciences, Geographic Information Sciences, Remote Sensing
Informed decisions to reduce deforestation, protect biodiversity, and curb carbon emissions require not just knowing where forests are, but understanding their composition. Identifying natural forests, which serve as critical biodiversity hotspots and major carbon sinks, is particularly valuable. We developed a novel global natural forest map for 2020 at 10 m resolution. This map can support [...]
Earthquake faults recorded in the near-shore bathymetry of Japan's back-arc
Published: 2025-04-27
Subjects: Geology, Geomorphology, Geophysics and Seismology, Tectonics and Structure
The eastern margin of the Sea of Japan is a zone of great seismic and tsunami hazard due to multiple offshore and nearshore reverse faults as shown by the 2024 Mw 7.5 Noto Peninsula Earthquake. Here we compare coseismic deformation of the 2024 Noto Peninsula Earthquake with 4767 individual marine terraces spanning the last Myr. This reveals that the earthquake faults started slipping between 326 [...]
Earth hit twice - The hypothesis of planetary rearrangement of the lithosphere by impact and interference waves
Published: 2025-04-26
Subjects: Earth Sciences, Physical Sciences and Mathematics, Planetary Geology, Planetary Geophysics and Seismology, Planetary Sciences
This study presents the impact-antipodal-interference hypothesis as a new model of planetary-scale crustal deformation. By analysing the distribution and properties of three megastructures - the Mariana Trench, the Mid-Atlantic Ridge, and the Amazon Basin - it is demonstrated that their formation may be linked to large-scale cosmic impacts and the seismic wave interference occurring within [...]
Institutional barriers to food safety in the urban irrigated vegetable value chain in Accra, Ghana
Published: 2025-04-26
Subjects: Environmental Studies
The faecal contamination of irrigation water threatens public health. Although safe practices can mitigate hygiene and food safety risks along the urban irrigated vegetable value chain, their adoption remains limited. A behaviour framework was combined with a participatory approach to explore how institutions influence farmers’ capability, opportunity and motivation to adopt safe practices in [...]
Uncertain seafood sustainability in a manufactured crisis
Published: 2025-04-26
Subjects: Aquaculture and Fisheries Life Sciences, Environmental Studies
In 2025, the United States (U.S.) administration issued a new Executive Order (EO), Restoring American Seafood Competitiveness, intensifying efforts to deregulate the seafood sector under the guise of promoting domestic industry. Building on the 2020 EO (Promoting American Seafood Competitiveness and Economic Growth), this policy marks a significant escalation in dismantling federal regulatory [...]
High risk, low concern: The climate perception gap in rural America
Published: 2025-04-26
Subjects: Public Health
Rural communities often demonstrate lower levels of concern and reduced support for climate mitigation and policies. This study examined views of climate risk and political support for climate action in Eastern North Carolina, a largely rural and agricultural region, with limited access to health care, and elevated environmental vulnerability. Understanding climate attitudes in this context is [...]
Swiss data quality: augmenting CAMELS-CH with isotopes, water quality, agricultural and atmospheric chemistry data
Published: 2025-04-26
Subjects: Life Sciences
In the era of large-sample hydrology (LSH) datasets, there is still limited availability of water quality data. Here, we introduce CAMELS-CH-Chem, an extension of CAMELS-CH (Catchment Attributes and Meteorology for Large-sample Studies in Switzerland), incorporating up to 40 water quality parameters for 115 catchments across Switzerland. This new dataset spans the period 1981–2020 and allows for [...]
Streamflow Hysteresis Analysis through a Deep Dive Budget of the St Venant Momentum Terms
Published: 2025-04-26
Subjects: Civil and Environmental Engineering, Engineering
Hysteretic conditions entail non-unique time-independent relationships in flow variables and are prevalent in the unsteady flow regime of most rivers worldwide. Estimation errors associated with the inability of current monitoring techniques to resolve hysteresis effects could have profound implications when the recorded data is used for water resources management and flood forecasting. A deep [...]
Back to Basics: On the Proper Determination of Free-Surface Slope (FSS) in Gradually Varied Open Channel Flows
Published: 2025-04-26
Subjects: Civil and Environmental Engineering, Engineering
This study is a fundamental evaluation of the fluvial wave propagation in river reaches affected by hysteresis, one of the most complex open-channel topics, materialized in loops and lags among hydraulic variables. Hysteresis processes are still understudied as measurements in natural streams for the whole wave propagation duration are hardly available, while the data from existing gaging sites [...]
Trend Analysis of Seasonal Temperature in the Al-Bardi region, Northeastern Libya
Published: 2025-04-25
Subjects: Geography
Abstract: This study investigates seasonal temperature trends in the Al-Bardī region, northeastern Libya, to identify potential climate change over recent decades. Due to limited local meteorological data, NASA POWER's 2-meter temperature records were used. Three statistical tools were applied: the Mann-Kendall test, simple linear regression, and first difference method. Findings from the [...]
Transforming Total Field Anomaly into Anomalous Magnetic Field: Using Dual-Layer Gradient-Boosted Equivalent Sources
Published: 2025-04-25
Subjects: Earth Sciences, Geophysics and Seismology, Physical Sciences and Mathematics
Potential field data often require interpolation onto a regular grid at constant height before further analysis. A widely used approach for this is the equivalent sources technique, which has been adapted over time to improve its computational efficiency and accuracy of the predictions. However, many of these approaches still face challenges, including border effects in the predictions or [...]
