Assessing forest fragmentation and biodiversity impacts in sub‐Saharan Africa: Methodological challenges and conservation strategies for small‐scale agricultural landscapes

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Tropical forests in sub‐Saharan Africa (SSA) harbor around one‐third of the world's species but are becoming more fragmented due to the expansion of human settlements and small‐scale agricultural (SCA) areas. This study systematically reviewed the approaches and methods used to analyze forest fragmentation and its impact on biodiversity in SSA,

Comparing WorldView-2 and PlanetScope Imagery to Mapping Housing Types Using GEOBIA

IOP Conference Series: Earth and Environmental Science, 2023
Abstract The mapping accuracy of housing types plays a vital role in urban planning and development. Choosing the right imagery for urban geospatial analysis matters in terms of spatial or textural resolution. Here we compare the effectiveness of different satellite imagery, namely WorldView-2 (2m resolution) and PlanetScope (3m ...

Performance Comparison of Deep Learning (DL)-Based Tabular Models for Building Mapping Using High-Resolution Red, Green, and Blue Imagery and the Geographic Object-Based Image Analysis Framework

Remote Sensing
Identifying urban buildings in high-resolution RGB images presents challenges, mainly due to the absence of near-infrared bands in UAVs and Google Earth imagery and the diversity in building attributes.

Trait‐Based Community Assembly in Early Tropical Forest Succession

Journal of Vegetation Science, Volume 36, Issue 6, November/December 2025.
We found that in early tropical forest succession, dispersal (landscape forest cover), management (previous land use extent and duration), and environmental filters (understory light availability) collectively shaped community assembly, each playing distinct roles.

Burned Area Detection in the Brazilian Amazon using Spectral Indices and GEOBIA

Revista Brasileira de Cartografia, 2020
Mapping refined burned areas (BA) in the Brazilian Amazon is still a challenge. The main difficulty of BA detection in large areas is the presence of cloud cover and water bodies. The use of different data sources of medium spatial resolution satellite images can provide a higher availability of cloud-free images.

Using Texture‐Based Image Segmentation and Machine Learning With High‐Resolution Satellite Imagery to Assess Permafrost Degradation Landforms in the Russian High Arctic

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Amplified climate change across the Arctic causes significant permafrost thaw and an increase of permafrost degradation landforms. These landforms range from fine‐scale degrading ice wedge‐polygon‐networks to large‐scale features such as thermo‐erosional gullies and reshape entire landscapes.

An Integrated Framework for the Assessment of Meso‐Scale Physical Habitats in Gravel‐Bed Rivers Using Remote Sensing and 2D Hydraulic Modeling

WIREs Water, Volume 12, Issue 3, May/June 2025.
A five‐step integrated modeling framework combines remote sensing and two‐dimensional hydraulic modeling to describe mesohabitats and assess suitability for target species. Remote sensing provides a Digital Terrain Model and an orthophoto (step 1) that can be used to classify and map environmental descriptors such as substrate and refugia (step 2).

Geographic Object-Based Image Analysis Framework for Mapping Vegetation Physiognomic Types at Fine Scales in Neotropical Savannas

Remote Sensing, 2020
Regional maps of vegetation structure are necessary for delineating species habitats and for supporting conservation and ecological analyses. A systematic approach that can discriminate a wide range of meaningful and detailed vegetation classes is still ...
