Assessment of wetland and vegetation dynamics in the context of urbanization and seasonal variation using surface indices in Ara city, India

Discover Geoscience
The pressure of rapid urbanisation has led to the rapid transformation of wetlands and vegetation, causing major problems for ecological sustainability in fast-growing cities.

An index for discrimination of mangroves from non-mangroves using LANDSAT 8 OLI imagery

MethodsX, 2018
Over the last few decades several vegetation indices were used to map Mangrove forest using satellite images. Difficulty still persists in discrimination of mangroves from non-mangrove vegetation, especially in areas where mangrove species are mixed with

Dataset of Coastline Positions for Sandy Beaches of England and Wales Derived Using Remote Sensing

Geoscience Data Journal, Volume 13, Issue 4, October 2026.
Two decades (1999–2020) of annual coastline position dataset were generated using COASTSAT toolkit for sandy beaches of England and Wales. The dataset consists of annual coastline position coordinates in the format of GeoJSON and Tabular files. ABSTRACT This article presents a dataset of coastline positions, comprising annual sandy coastline detections

Evaluating Gross Primary Production (GPP) Trends Due To Changes in Greenness From the Satellite Data‐Driven FluxSat Product

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Accurate estimation of gross primary production (GPP), the mass of carbon fixed by plants through photosynthesis, and long‐term GPP trends is essential for monitoring ecosystems, analyzing the carbon cycle, and evaluating biosphere models.

Long‐term monitoring and remote sensing reveal waterbird colony collapses with rising lake levels and multiple stressors

Ecological Applications, Volume 36, Issue 6, September 2026.
Abstract Global climate change is expected to exacerbate existing environmental stressors and increasingly impact biodiversity. While likely widespread, changes in wildlife populations resulting from the interaction of climate change and other environmental stressors remain poorly understood.

A hierarchical unmanned aerial system–light detection and ranging–satellite learning framework for scaling heterogeneous vegetation cover mapping in rangelands

Grassland Research, Volume 5, Issue 3, Page 245-269, September 2026.
This study shows how drones, light detection and ranging (LiDAR), and satellites can be combined to map vegetation in rangelands more effectively. Drone imagery captures fine‐scale plant details, LiDAR adds information about vegetation structure and height, and satellite data allow the mapping approach to be expanded across larger areas.

Divergent Blue Carbon Trajectories in the Yellow River Delta Post‐1976 Diversion: Hydrological Stability and Human Disturbance Contrasts Revealed by Multi‐Source Remote Sensing (1984–2023)

Land Degradation &Development, Volume 37, Issue 15, Page 11417-11437, September 2026.
ABSTRACT Coastal wetlands are critical blue carbon sinks, yet their spatiotemporal dynamics under environmental change remain insufficiently quantified. Taking the Yellow River Delta (YRD) as a natural laboratory, this study synthesizes multi‐source remote sensing data, including optical and radar imagery spanning from 1984 to 2023, to explore the ...
