Climate‐Driven Mangrove Dieback and Recovery: A Case Study in Albert and Leichhardt Rivers, Australia

Remote Sensing in Ecology and Conservation, EarlyView.
Cycles of dieback and recovery drove mangrove forest dynamics at the Albert and Leichhardt Rivers (Gulf of Carpentaria, Queensland, Australia) over 36 years (1987–2023). Landward margins were the most affected by reduced tidal inundation when the alignment of low lunar declination suppressed tidal range and extreme El Niño phases lowered mean sea level.

Analisis Dataran Banjir Menggunakan Spatial Computing MNDWI Dengan Sentinel 2 di Danau Rawa Pening

MAJALAH PEMBELAJARAN GEOGRAFI, 2023
Danau Rawa Pening menjadi sistem penyimpanan air yang penting bagi masyarakat Kabupaten Semarang. Danau Rawa Pening memiliki permasalahan terhadap pendangkalan yang disebabkan salah satunya karena faktor eutrofikasi oleh tanaman eceng gondok. Pendangkalan danau berdampak buruk terhadap kapasitas penyimpanan air, sehingga dapat berpotensi mengalami ...

MNDWI and BSI for Monitoring Land Degradation in Gresik Regency

IOP Conference Series: Earth and Environmental Science
Abstract Land degradation or land productivity declined in Indonesia, reaching 25.1% in 2014. However, in East Java, land degradation showed a downward trend from 2006 to 2018. This land degradation process was expected to affect the condition of agriculture and plantations in the region.

Seasonal Variations of the Relationship between Spectral Indexes and Land Surface Temperature Based on Local Climate Zones: A Study in Three Yangtze River Megacities

Remote Sensing, 2023
Urban heat islands are representative problems in urban environments. The impact of spectral indexes on land-surface temperature (LST) under different urban forms, climates, and functions is not fully understood.

An Explainable and Optimized Machine Learning Framework for Multisensor Remote Sensing‐Based Land Use and Land Cover Classification

Transactions in GIS, Volume 30, Issue 3, May 2026.
ABSTRACT Land use and land cover (LULC) mapping supports environmental monitoring and spatial planning, but classification performance often suffers in feature spaces that combine multiple data sources with redundant predictors. This study compares five feature selection methods (mRMR, ReliefF, Boruta, RFE, HSIC‐Lasso) with three tree‐based classifiers

Unequal Land and Water Changes Between Nations Driven by International Boundary Rivers: Mapping and Temporal Analysis of Shared Borders Between China and Its Neighbors

Earth's Future, Volume 14, Issue 4, April 2026.
Abstract International Boundary Rivers (IBRs), as natural political frontiers, constitute one‐third of China's land borders. However, a lack of systematic monitoring has led to a limited understanding of the distribution of these politically significant rivers and the potential risks posed by their dynamic nature.

Can Water-Detection Indices Be Reliable Proxies for Water Discharges in Mid-Sized Braided Rivers Using Coarse-Resolution Landsat Archives?

Remote Sensing, 2023
The use of water detection (WD) indices to infer daily discharge (Qd) has a great potential to enrich needed hydrological data for understanding fluvial processes driving the morphological changes of braided rivers. However, no consensus has been reached

Dendrochronology and remote sensing reveal beaver occupancy and colonization dynamics in an expanding Arctic population

Ecosphere, Volume 17, Issue 3, March 2026.
Abstract The North American beaver (Castor canadensis) is expanding its distribution in the Arctic tundra. Due to the species' capacity to engineer ecosystems, they can transform surface water dynamics and biogeochemistry, permafrost stability, vegetation composition, and impact Indigenous subsistence practices.

Quantifying river morphological changes using multi‐satellite observations and in situ measurements

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
This study integrates optical, radar and altimetry satellite data with river gauge measurements to estimate periodically submerged riverbed topography and quantify morphological change. By linking how often water covers the riverbed with water‐level variations, erosion and deposition patterns are mapped across a reach of Jamuna River.
