Deep Learning for Satellite‐Based Forest Disturbance Monitoring: Recent Advances and Challenges

WIREs Data Mining and Knowledge Discovery, Volume 16, Issue 2, June 2026.
Overview of key research challenges in forest disturbance monitoring, including the detection of disturbances of varying severity, the attribution of disturbance agents, and the development of models capable of generalizing across regions. ABSTRACT Climate change and land use pressures are intensifying forest disturbances in many world regions, as ...

The Decline of a Caldera‐Filling Glacier at Volcán Sollipulli, Chile

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Southern Andean glaciers have undergone fast retreat in recent decades. This results in reduced freshwater storage, contribution to sea‐level rise, and locally to the formation of glacial lakes, that may pose the risk of glacial lake outburst floods (GLOFs).

Delirium Screening in the Emergency Department: Barriers, Enablers and Alignment With Clinical Standards—A Mixed‐Methods Study

Emergency Medicine Australasia, Volume 38, Issue 3, June 2026.
ABSTRACT Objective Delirium is common and serious among older adults in emergency departments (EDs) yet screening often falls short of national expectations. This study evaluated current delirium screening practices in a metropolitan ED and identified barriers and enablers to implementing screening in line with the Australian Delirium Clinical Care ...

Assessing canopy height measurements from ICESat-2 and GEDI orbiting LiDAR across six different biomes with G-LiHT LiDAR

Environmental Research: Ecology
The height of woody plants is a defining characteristic of forest and shrubland ecosystems because height responds to climate, soil and disturbance history.

Impact of fire severity on forest structure and biomass stocks using NASA GEDI data. Insights from the 2020 and 2021 wildfire season in Spain and Portugal

Science of Remote Sensing
Wildfires have been progressively shrinking the C sink capacity of forest accelerating climate change effects on forest biodiversity, especially where megafires are recurrent and of increased frequency such as in the Mediterranean.

Accuracy assessment of LAI, PAI and FCOVER from Sentinel-2 and GEDI for monitoring forests and their disturbance in Central Germany

European Journal of Remote Sensing
Forest monitoring benefits from biophysical parameters such as Leaf Area Index (LAI), Plant Area Index (PAI) and fractional vegetation cover (FCOVER) and can be obtained from optical and LiDAR remote sensing, such as Sentinel-2 (S2) and the Global ...

Genome-Enhanced Detection and Identification (GEDI) of plant pathogens

PeerJ, 2018
Plant diseases caused by fungi and Oomycetes represent worldwide threats to crops and forest ecosystems. Effective prevention and appropriate management of emerging diseases rely on rapid detection and identification of the causal pathogens. The increase in genomic resources makes it possible to generate novel genome-enhanced DNA detection assays that ...

Validation of the vertical canopy cover profile products derived from GEDI over selected forest sites

Science of Remote Sensing
Canopy cover (CC) quantifies the proportion of canopy materials projected vertically onto the ground surface. CC is a crucial canopy structural variable and is commonly used in many ecological and climatic models.
