Ask the Government of India if things have worked out for them with their flagship scheme for the Border Villages, the honest answer (on parliamentary record) is No, it has never been verified anywhere. The Vibrant Villages Programme (VVP-I) has approved around ₹4,800 crore in support of 2,967 villages in five Himalayan border states/union territories including 662 villages marked 'priority' for [...]
Deglacial Mass-Movement Floods as a Potential Source of Catastrophic Flood Traditions: A Testable Geomythological Hypothesis
Published: 2026-09-05
Subjects: Earth Sciences, Geology, Geomorphology, Glaciology, Hydrology
Catastrophic flood traditions occur in many geographically separated cultures, but their possible geological substrates need not be uniform. Existing explanations include river floods, earthquake and volcanic tsunamis, glacial-lake outburst floods, postglacial sea-level rise, and cultural transmission. This paper proposes a complementary, explicitly testable hypothesis: during the terminal [...]
Methodological Bias between Trajectory Geometric Co-location and Air-Parcel Lagrangian Co-location: Evidence from UAV Re-penetration Observations over the Western Sichuan Plateau
Published: 2026-09-05
Subjects: Atmospheric Sciences, Meteorology
Whether "trajectory geometric co-location" is equivalent to "air-parcel Lagrangian co-location" remains a methodological blind spot in evaluating UAV cloud-seeding re-penetration (the UAV performed a repeated cloud penetration—hereafter, re-penetration—to re-sample the same cloud volume). Using silver iodide (AgI) seeding observations from a Wing Loong-2 UAV flight over the Western Sichuan [...]
ECOCIDE: Quantifying War-Time Environmental Damage: A Difference-in-Differences Analysis of the Kakhovka Dam Destruction
Published: 2026-09-05
Subjects: Applied Statistics, Biodiversity, Earth Sciences, Environmental Sciences, Geographic Information Sciences, Geography, Human Geography, International and Area Studies, Other Geography, Physical and Environmental Geography, Remote Sensing, Spatial Science, Statistical Methodology, Statistical Models, Statistics and Probability
Abstract: International law organisations are actively looking into declaring "ecocide" -- mass environmental destruction -- as a prosecutable international crime and in September 2024, Vanuatu, Fiji and Samoa submitted a proposed amendment to Rome Statute. No consistent, statistically sound method yet has been developed to document such a claim of harm, however, because prior environmental [...]
Independent Verification of the European Climate Law's Effect on Nitrogen Dioxide Pollution: A Satellite-Derived, Difference-in-Differences Analysis

Small islands are widely assumed to face a compounding climate risk: high physical exposure to sea-level rise, layered on top of degrading natural coastal defenses. That assumption is rarely tested against independent, multi-temporal evidence, and rarely broken down by ecosystem type — so I tested it directly, across five islands spanning three ocean basins: Maldives, Lakshadweep, Seychelles, [...]
Systematic Evaluation of a Transformer-Based Surrogate for Distributed Groundwater Dynamics: Long-Horizon Prediction, Dynamic–Static Fusion, and Data Augmentation
Published: 2026-09-05
Subjects: Engineering, Physical Sciences and Mathematics
Transformers are increasingly reshaping artificial-intelligence-based Earth system prediction, yet their suitability for distributed groundwater surrogate modeling remains poorly understood. Groundwater dynamics combine strong temporal persistence with spatial interactions governed by heterogeneous hydrogeological conditions. These characteristics make attention-based architectures potentially [...]
Competing Psychological Pathways Linking Age and Individual and Collective Pro-Environmental Behavior Intentions: The Role of Conservatism
Published: 2026-09-04
Subjects: Environmental Studies
Promoting pro-environmental behavior (PEB) across the lifespan is critical for achieving an effective response to climate change. This may particularly be important in later life, as older adults hold substantial economic resources and electoral influence, enabling them to shape societal responses to environmental challenges. However, they have also been found to be more likely than younger [...]
Healthcare professionals at the frontline of Climate Change: knowledge, attitudes, and practices
Published: 2026-09-04

Healthcare professionals (HCPs), as trusted cadre of community, play a crucial role advocating climate action to reduce its impact on health. This study aimed to assess the knowledge, attitudes, practices and perceived responsibilities (KAPP), associated factors, of healthcare providers in Karachi, Pakistan, regarding climate change and its associated health effects. We conducted a [...]
Abundance and Spatial Distribution of Third Generation Cephalosporin Resistant Escherichia coli in Wastewater and impact on the receiving Korle Lagoon, Accra, Ghana
Published: 2026-09-04
Subjects: Microbiology
Antimicrobial resistance in the environment is a major public health threat, particularly in low- and middle-income countries where there is inadequate wastewater treatment infrastructure. Third generation cephalosporin resistant Escherichia coli (3GCR E. coli) are of particular concern as they have clinical significance and may spread associated resistance genes in environment. This study [...]
A multicriteria decision analysis framework for generating baseline virtual weather stations in Zimbabwe
Published: 2026-09-04
Subjects: Oceanography and Atmospheric Sciences and Meteorology
In this study, we generate baseline Virtual Weather Stations (VWS) in locations with minimal atmospheric noise by avoiding two major surface factors known to cause noise in remotely sensed weather observations. The study also proposes an improvement to the spatial coverage of Zimbabwe's weather observation network through the identification of environmentally suitable locations for virtual [...]
Testing the Fluorescence Advantage: Solar-Induced Fluorescence as an Early Indicator of Agricultural Drought Stress in Marathwada, Maharashtra
Published: 2026-09-04
Subjects: Agriculture, Biodiversity, Ecology and Evolutionary Biology, Environmental Studies, Forest Sciences, Geographic Information Sciences, Geography, Nature and Society Relations, Remote Sensing, Spatial Science
Drought detection in India, both for official declaration purposes and for triggering payouts under the Pradhan Mantri Fasal Bima Yojana (PMFBY) crop-insurance scheme, still leans heavily on rainfall-deficit records and the Normalized Difference Vegetation Index (NDVI) — two signals that only move once a crop has already begun to visibly suffer. This study asks whether Solar-Induced Fluorescence [...]
Ghost Infrastructure: Historical Industrial Geography and the Persistence of Path-Dependent Accessibility in Bochum, Germany

Karewa terraces are elevated, flat-topped deposits of intermontane lake-basin age (Pleistocene/Pliocene), and they underlie one of Kashmir's most economically significant agricultural systems — the saffron-growing belt at Pampore. Everyone who follows agriculture in Kashmir already knows these terraces are vanishing under unregulated soil mining and uncontrolled urban expansion; there's ample [...]
Magnitude-order improvements to the measurement precision of Antarctic grounding zone dynamics using SAR satellite constellations
Published: 2026-09-04
Subjects: Aerospace Engineering, Earth Sciences, Engineering, Geophysics and Seismology, Glaciology
Glacier loss in Antarctica is strongly influenced by melt in the grounding zone, the transition between grounded and floating ice. Thwaites Glacier is a critical region, with 65 cm of sea-level-equivalent ice. A recent dataset tracks grounding line retreat for Thwaites and other Antarctic ice streams over 30 years. Despite this long-term record, significant uncertainty remains in predictions of [...]
