PyRiverShift: A Gaussian Transect Decomposition Framework for Quantifying Sub-Pixel Lateral Channel Mobility
Published: 2026-08-16
Subjects: Applied Statistics, Earth Sciences, Environmental Indicators and Impact Assessment, Environmental Monitoring, Geomorphology, Hydrology, Physical Sciences and Mathematics, Sedimentology, Water Resource Management
Along many rivers, lateral channel mobility is a key process, yet quantification from freely available multi-decadal 30 m Landsat imagery is constrained by low pixel resolution relative to channel width. We introduce PyRiverShift, a sensor-agnostic spectral decomposition framework. PyRiverShift fits a 1-D Gaussian to NDWI profiles along valley-perpendicular transects, recovering sub-pixel channel [...]
Hydroclimatic Regime Shifts and Compound Heat–Dry Events in Rajshahi Division, Bangladesh: Integrating Thermal Gradients, Change-Point Detection, and Heat-Driven Dryness Dynamics (1992–2022)
Published: 2026-08-07
Subjects: Climate, Environmental Indicators and Impact Assessment, Environmental Monitoring, Hydrology, Meteorology, Other Earth Sciences, Other Oceanography and Atmospheric Sciences and Meteorology, Statistical Models
Hydroclimatic variability and compound climate extremes are increasingly affecting monsoon-dominated regions of South Asia, particularly drought-prone northwestern Bangladesh. However, integrated assessments of thermal dynamics, atmospheric moisture, land–atmosphere coupling, and compound heat–dry events remain limited in the regional context. Therefore, this study investigated long-term [...]
Twin indicators of coastal vulnerability: land subsidence and mangrove extent change in Dili, Timor-Leste
Published: 2026-08-06

Mangrove forests and land subsidence are major drivers of coastal vulnerability rarely quantified together outside the well-studied deltas of Southeast Asia. This study provides the first satellite-based, twin-indicator assessment of coastal vulnerability for Dili, Timor-Leste, combining Sentinel-1 InSAR time series analysis of land subsidence with Global Mangrove Watch extent change over a [...]
From linguistic evaluation to mechanistic verification: testing LLM-generated farm recommendations
Published: 2026-07-03
Subjects: Agricultural Science, Agriculture, Agronomy and Crop Sciences Life Sciences, Biochemistry, Biophysics, and Structural Biology, Biogeochemistry, Environmental Indicators and Impact Assessment, Research Methods in Life Sciences, Soil Science, Sustainability
Large language models (LLM) are increasingly used to generate farm-management advice, but their biophysical consequences remain largely unverified. We introduce a process-based verification framework that combines management portfolios generated by ChatGPT and Claude with the process-based model LandscapeDNDC across 11 contrasting agroecosystems. The LLMs produced agronomically plausible [...]
Spatially Distributed Land-Use Efficiency Assessment under SDG Indicator 11.3.1: The Case of Greater Manila Area, Philippines
Published: 2026-06-06
Subjects: Environmental Indicators and Impact Assessment, Environmental Monitoring, Environmental Sciences, Sustainability
Sustainable Development Goal (SDG) Indicator 11.3.1 assesses urban land-use efficiency (LUE) through the relationship between land consumption rate (LCR) and population growth rate (PGR), commonly expressed as LCRPGR. However, city-level implementation produces a single value that can mask where efficient or inefficient urban development occurs. This study develops and demonstrates a spatially [...]
Global Temperature Anomalies in Practice: An Open, Reproducible Framework for Baseline Harmonisation and ENSO-Aware Visualisation
Published: 2026-06-02
Subjects: Environmental Indicators and Impact Assessment, Environmental Sciences
We present a reproducible pipeline for downloading, processing, and harmonising global temperature anomaly series from HadCRUT5, GISTEMP, NOAAGlobalTemp, Berkeley Earth, and ERA5. All datasets are aligned to a common 1850-1900 pre-industrial baseline to enable direct comparison. The workflow also integrates the Oceanic Niño Index (ONI) to annotate El Niño and La Niña phases in the figures, [...]
A Blueprint for Integrated Climate Intelligence
Published: 2026-05-13
Subjects: Artificial Intelligence and Robotics, Environmental Indicators and Impact Assessment, Environmental Monitoring, Planetary Sciences, Sustainability
Climate information is advancing faster than the decision systems designed to use it. Emergency response operates on timescales of hours, whereas societal adaptation unfolds over decades. Yet climate science, impact assessment and policy remain poorly integrated, limiting coherent action across timescales. We argue that artificial intelligence should be developed not only as a domain-specific [...]
A Foundational Synthesis of Ecosystem Services Knowledge to Critically Assess and Structure Their Integration into Life Cycle Impact Assessment
Published: 2026-05-11
Subjects: Environmental Indicators and Impact Assessment
Purpose: The integration of ecosystem services in life cycle assessment has gained increasing attention. Its operationalization remains limited and inconsistent, particularly within the impact assessment phase. This study provides the first comprehensive and structured critical review that bridges foundational ecosystem services knowledge with life cycle assessment modeling needs. Method: We [...]
Spatiotemporal Evolution of Urban Thermal Conditions, Vegetation Dynamics, and Built-up Expansion in Ahmedabad, India (2000–2025) Using Multi-Temporal Landsat Analysis.
Published: 2026-05-11
Subjects: Climate, Environmental Indicators and Impact Assessment, Environmental Monitoring, Environmental Sciences, Sustainability, Terrestrial and Aquatic Ecology
Rapid urban expansion has substantially altered urban thermal conditions across many semi-arid cities. This study examined spatiotemporal variation in land surface temperature (LST), vegetation cover, and built-up intensity across Ahmedabad, India, between 2000 and 2025 using multi-temporal Landsat imagery and the Google Earth Engine (GEE) platform. Spatial analysis revealed progressive expansion [...]
Challenges with Developing a Measurement-Based Basin Methane Intensity Estimate: A Case Study from the Haynesville
Published: 2026-04-30
Subjects: Environmental Indicators and Impact Assessment, Environmental Monitoring, Oil, Gas, and Energy
Methane intensity, the emissions relative to production, has been a focus in global regulations on oil and gas production and imports, given the climate benefits of methane emission reductions. Methodological frameworks to create annual measurement-based emissions inventory estimates and calculate methane intensity using snapshot measurements have been developed. However, there are still multiple [...]
