Floods From Space: How Remote Sensing, AI, and Cloud Platforms Are Reshaping Disaster Risk Reduction

Journal of Flood Risk Management, Volume 19, Issue 3, September 2026.
ABSTRACT Flooding remains one of the most damaging climate‐related hazards globally, yet flood remote sensing has historically developed largely along sensor‐specific pathways. This review addresses the need for a systematic and decision‐oriented synthesis of how space‐borne remote sensing has evolved toward integrated flood monitoring and disaster ...

Zagros Restoration: Smart Choices for Oak Forests

Land Degradation &Development, Volume 37, Issue 14, Page 10284-10307, 30 August 2026.
ABSTRACT Widespread forest degradation across the northern Zagros region of Iran driven by both human activity and natural processes has created an urgent need for targeted afforestation and forest enrichment strategies. Hence, the aim of this study was identifying the most suitable native tree and shrub species for restoring degraded forest areas in ...

Mapping land subsidence over the eastern Beijing city using satellite radar interferometry

International Journal of Digital Earth, 2018
Beijing City has suffered from groundwater-induced subsidence since the late 1930s and the over-exploration of groundwater could lead to subsidence as much as −12.0 cm yr−1. Previous studies on the ground deformation at Beijing City mainly focused on the

Preliminary Study on the Radar Vegetation Index (RVI) Application to Actual Paddy Fields by ALOS/PALSAR Full-polarimetry SAR Data [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
Kim and van Zyl (2001) proposed a kind of radar vegetation index (RVI). RVI = 4*min(λ1, λ2, λ3) / (λ1 + λ2 + λ3) They modified the equation as follows. (2009) RVI = 8 * σ0hv / (σ0hh + σ0vv +σ0hv ) by L-band full-polarimetric SAR data.

Fault‐controlled uplift segmentation and crust–mantle heterogeneity in the topographic evolution of the Sındırgı Segment (Western Anatolia) ruptured during the 2025 M6.1 earthquake sequence

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Swath profile along the Sındırgı Segment. Grey curves show minimum, mean and maximum elevations, and the thick grey line shows elevation‐corrected Moho depth. Coloured circles indicate relative rock uplift from river‐profile inversion while the red curve shows cumulative uplift.

Polarimetric Measures in Biomass Change Prediction Using ALOS-2 PALSAR-2 Data

Remote Sensing
The use of multiple synthetic aperture radar polarizations can improve biomass estimations compared to using a single polarization. In this study, we compared predictions of aboveground biomass change from ALOS-2 PALSAR-2 backscatter using linear ...

Early Deforestation Detection in the Tropics using L-band SAR and Optical multi-sensor data and Bayesian Statistics

International Journal of Applied Earth Observations and Geoinformation
The growing availability of medium-resolution optical and radar satellite observations has prompted the development of synergistic change detection methodologies. Timely forest change detection, particularly early deforestation, is crucial for preventing
