Advancing the Mapping of Mangrove Forests at National-Scale Using Sentinel-1 and Sentinel-2 Time-Series Data with Google Earth Engine: A Case Study in China

Remote Sensing, 2020
A high resolution mangrove map (e.g., 10-m), including mangrove patches with small size, is urgently needed for mangrove protection and ecosystem function estimation, because more small mangrove patches have disappeared with influence of human ...

Causes and Contributing Factors of In‐Hospital and Post‐Discharge Mortality Among Patients With Severe Acute Respiratory Infection in Low‐ and Middle‐Income Countries: A Scoping Review

Health Science Reports, Volume 9, Issue 9, September 2026.
ABSTRACT Background and Aims Severe acute respiratory infections (SARI) remain a major cause of global morbidity and mortality, with a disproportionate burden in low‐ and middle‐income countries (LMICs). Although in‐hospital mortality is frequently reported, deaths occurring after hospital discharge remain poorly documented.

Land Use and Land Cover Analysis for Solid Waste Management in NCT Delhi Using Fusion Aware Segformer

Land Degradation &Development, Volume 37, Issue 15, Page 10672-10696, September 2026.
ABSTRACT The use of Land Use Land Cover (LULC) analysis is a fundamental requirement for urban solid waste management (SWM); however, conventional LULC analysis methods are not well suited to the spatio‐temporal variability, multi‐sensor heterogeneity, and seasonal variations of highly dynamic urban environments.

Mapping Soil Salinity Prediction Enhanced by Time‐Series Remote Sensing Features

Land Degradation &Development, Volume 37, Issue 15, Page 10927-10943, September 2026.
ABSTRACT Gaining timely knowledge of soil salinity's spatiotemporal dynamics is crucial for accurate mapping. Through temporal span comparisons, this study systematically extracts and utilizes time‐series features (TSFs) derived from Sentinel‐2 and Landsat 8 NDVI and SAVI data (2019–2023) to enhance prediction accuracy. Three datasets were constructed:

Assessing SWOT's Measurement Capabilities in the Complex Paraná River

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Estimating water surface elevation (WSE) is crucial for understanding hydrological processes; however, many rivers remain insufficiently monitored due to the limitations of in situ gauge networks. The Surface Water and Ocean Topography (SWOT) mission, equipped with Synthetic Aperture Radar technology, enables global monitoring of WSE with high
