Trade‐Offs of Conservation Fencing in Western Serengeti: Enhancing Agricultural Security While Navigating Unintended Consequences on Land‐Use Dynamics

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Fencing enhanced security in cropland livestock grazing land. Fence did not have a significant change in crop zonation patterns. While local communities are largely happy with the fence, fencing triggered land‐use conflicts and the resettlement of a few livestock keepers with large herds of livestock to nearby unfenced sites.

Seasonality, barrage (Farakka) regulated hydrology and flood scenarios of the Ganga River: a study based on MNDWI and simple Gumbel model [PDF]

Modeling Earth Systems and Environment, 2016
The hydrology of the Ganga River is mainly characterized by high monsoon rainfall and seasonal variability in discharge flow. The study is focuses on both the up and down-streams of Farakka barrage. It has been executed with the help of Modified Normalized Difference Water Index using Landsat satellite images (2014), satellite based discharge data and ...

Rapidly declining seagrass meadows in Brazil: Findings from satellite imagery and local knowledge

People and Nature, Volume 8, Issue 5, Page 1155-1171, May 2026.
Abstract Due to the limitations of individual monitoring approaches, integrating social perceptions with multiple advanced technologies provides a new opportunity to gain a comprehensive understanding of ecosystem degradation. We combined historical aerial mapping, satellite imagery, semi‐structured interviews with local stakeholders, and a bilingual ...

Enhancing flood inundation mapping technique using Landsat-based remote sensing and 2D hydrodynamic modeling: a case study of the Bihar flood caused by the Koshi embankment breach

Frontiers in Remote Sensing
Floods have become more unpredictable and erratic due to the influence of extreme hydroclimatic events. Therefore, obtaining near-real-time, accurate flood inundation maps for such events is essential for effective flood emergency response, which can be ...

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

Spatiotemporal Analysis Of Flood Inundation Using MNDWI At Rawa Pening 2019-2025

Jambura Geoscience Review
Flood inundation around Rawa Pening Lake has intensified in recent years, yet long-term patterns of inundation extent and persistence remain poorly quantified. This study aims to analyse the interannual and spatial dynamics of flood inundation in the Rawa Pening lake-basin system during 2019–2025 and to identify riparian zones that experience recurrent

Automated detection of Yarka island (Baikal lake) based on NDWI, MNDWI and WRI spectral indices

InterCarto InterGIS
The paper presents the results of an automated algorithm designed to detect Yarki Island on satellite imagery and estimate its area utilizing Python-based tools. Employing the developed algorithm for calculating spectral indices—WRI (Water Ratio Index), NDWI (Normalized Difference Water Index), and MNDWI (Modified Normalized Difference Water Index)—we ...

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.

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.
