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, [...]
Testing the Fluorescence Advantage: Solar-Induced Fluorescence as an Early Indicator of Agricultural Drought Stress in Marathwada, Maharashtra
Published: 2026-09-05
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 [...]
Stolen Strata: Quantifying the Anthropogenic Erasure of Kashmir's Karewa Terraces and Its Threat to the Saffron Economy
Published: 2026-09-05
Subjects: Agriculture, Biodiversity, Earth Sciences, Environmental Sciences, Environmental Studies, Geographic Information Sciences, Geography, Geomorphology, Nature and Society Relations, Other Geography, Remote Sensing, Spatial Science
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 [...]
Ghost Infrastructure: Historical Industrial Geography and the Persistence of Path-Dependent Accessibility in Bochum, Germany

Subjects: Earth Sciences, Environmental Sciences, Environmental Studies, Geographic Information Sciences, Geography, Human Geography, Nature and Society Relations, Other Geography, Remote Sensing, Spatial Science, Statistics and Probability
The complete 69,393 pedestrian street node network from Bochum was used for a Welch's t-test, which revealed as a surprise that street nodes with low accessibility are actually significantly farther from historical industrial sites than street nodes with high accessibility (t=42.887, p<0.00001, Cohen's d=0.589 - medium-to-large effect), which is the opposite of what the original hypothesis [...]
Measured or assumed? Regulatory defaults, ownership, and the measurement content of the U.S. greenhouse gas inventory
Published: 2026-09-04
Subjects: Environmental Studies, Nature and Society Relations, Risk Analysis
Municipal solid waste landfills are the third-largest anthropogenic source of methane in the United States, and the national inventory for this source is assembled almost entirely from facility self-reports filed under Subpart HH of the Greenhouse Gas Reporting Program (GHGRP). Airborne and satellite surveys estimate actual emissions at 1.4 to 2.7 times reported levels, but remote sensing alone [...]
Global Power Outage Detection at the Kilometer Scale from Satellite Nighttime Lights
Published: 2026-08-28
Subjects: Artificial Intelligence and Robotics, Geographic Information Sciences, Geography, Human Geography, Nature and Society Relations, Power and Energy, Public Health, Remote Sensing
Satellite nighttime light observations show great promise for remote sensing of power outages, yet have only been utilized in limited case studies to date. Here, we present generalized detection of power outages across the globe at ~1-kilometer resolution. Our method, the Outage frameWork for Luminosity Interruptions (OWL-I), reveals the power outages can be reliably detected from VIIRS/Black [...]
Observed warming is shrinking favourable daylight windows for outdoor recreation: evidence from sports facilities across France
Published: 2026-08-25
Subjects: Climate, Nature and Society Relations
Observed warming is changing not only the severity of heat exposure during outdoor recreation, but also the time of day when thermally favourable conditions remain available. We quantify this emerging temporal constraint across metropolitan France from 1991 to 2025 by combining hourly ERA5-Land meteorology, Wet-Bulb Globe Temperature (WBGT), solar geometry and the national Data ES inventory of [...]
Spatial Recognition Justice: Integrating Participatory Mapping and Discrete Choice Experiment to Elicit Ecosystem Service Values
Published: 2026-08-22
Subjects: Environmental Indicators and Impact Assessment, Environmental Monitoring, Geographic Information Sciences, Nature and Society Relations, Other Environmental Sciences, Spatial Science
Nature-based solutions (NBS) have become a central component of climate adaptation and sustainability agendas in many cities. Yet NBS implementation increasingly faces opposition from residents. As NBS fail to consider diverse needs, values, and priorities of different population segments, they fall short from a recognition justice perspective. This study provides a systematic assessment of [...]
Annual high-resolution global ambient population estimates from 1975 to 2024

Gridded population data support assessments of human exposure, settlement change, infrastructure demand, and access to services, yet global datasets combining annual coverage over multiple decades with fine spatial resolution remain limited. LandScan Mosaic Time Series provides 50 annual estimates of global ambient population distribution at 3 arc-second resolution from 1975 through 2024. The [...]
Unequal scaling of urban vegetation cooling across sociodemographic groups
Published: 2026-07-30
Subjects: Environmental Sciences, Nature and Society Relations
Urban vegetation mitigates heat in cities, but its benefits often reach disadvantaged residents least, an inequality of growing concern as climate change intensifies urban heat. Whether residence-based cooling exposure and its inequality scale systematically with population size and density, as infrastructural and socioeconomic attributes do, remains unclear. Here, we simulate process-based [...]
Thermal migration and climatic de-territorialisation of North American professional sports leagues, 1950–2025
Published: 2026-07-28
Subjects: Geographic Information Sciences, Nature and Society Relations, Physical and Environmental Geography
Over the past seven decades, the four major North American professional sports leagues (NHL, MLB, NBA, NFL) have expanded and relocated across the continent, shifting their collective geography towards the Sun Belt. We quantify the climatic consequences of this movement by combining the complete franchise location history of the four leagues from 1950 to 2025 with ERA5-Land reanalysis data and [...]

Wildfires pose an increasing risk to structures and communities located adjacent to or among vegetative landscapes. Yet most open landscape-scale fire modeling workflows still lack a reproducible way to represent buildings as combustible fuels rather than only as exposed assets or nonburnable developed land. This paper presents FireDX, a geospatial data engine that generates standardized, [...]
