Mineralogical characterisation of aeolian sands using multispectral satellite datasets: Implications for dune field evolution, Wahiba Dune Field, Oman

Earth Surface Processes and Landforms, Volume 50, Issue 6, May 2025.
This study develops a remote sensing methodology that integrates high‐resolution satellite imagery with field validation to map the Wahiba Dune Field of Oman. Findings reveal the sensitivity of contemporary geomorphic surfaces to local sediment dynamics and highlight the value of multi‐scale analysis in interpreting dune field evolution.

Aboveground Biomass in West African Semi‐Arid Ecosystems: Structural Diversity, Taxonomic Contributions and Environmental Drivers

Journal of Sustainable Agriculture and Environment, Volume 4, Issue 1, March 2025.
ABSTRACT The role of plant diversity and biomass in ecosystem functioning and management is well recognized. However, the structural drivers of aboveground biomass (AGB) and their influence across savanna ecosystems remain understudied, particularly in semi‐arid regions.

Machine Learning and Spatio Temporal Analysis for Assessing Ecological Impacts of the Billion Tree Afforestation Project

Ecology and Evolution, Volume 15, Issue 2, February 2025.
This study evaluates Pakistan's Billion Tree Afforestation Project in KPK province using Random Forest classification and Sentinel‐2 imagery, revealing a 4.97% increase in tree cover from 2015 to 2023. Hotspot analysis showed increased vegetation clustering, while an ANN model predicted NDVI with high accuracy, identifying soil moisture and ...

Comparison of Methods to Derive the Height‐Area Relationship of Shallow Lakes in West Africa Using Remote Sensing

Water Resources Research, Volume 61, Issue 2, February 2025.
Abstract In West Africa, lakes and reservoirs play a vital role as they are critical resources for drinking water, livestock, irrigation, and fisheries. Given the scarcity of in‐situ data, satellite remote sensing is an important tool for monitoring lake volume changes in this region.

Satellite Observations Reveal a Positive Relationship Between Trait‐Based Diversity and Drought Response in Temperate Forests

Global Change Biology, Volume 31, Issue 2, February 2025.
The relationship between functional diversity (richness, evenness) and drought response (resistance, recovery, resilience) during the severe 2018 drought in Switzerland was analyzed using satellite‐derived data. The Sentinel‐2 data revealed that forests with greater canopy trait diversity showed higher resistance and resilience to drought.

Investigation of Water Quality in Izmir Bay With Remote Sensing Techniques Using NDCI on Google Earth Engine Platform

Transactions in GIS, Volume 29, Issue 1, February 2025.
ABSTRACT In this study, the effects of algal blooms occurring in Izmir Bay in the summer of 2024 on marine ecosystems were investigated using remote sensing techniques on Google Earth Engine platform. The normalized difference chlorophyll index (NDCI) was calculated from January to the end of September and the chlorophyll‐a density was analyzed ...
