Improving Olive Yield Prediction Using Landsat Multispectral Data and Advanced Ensemble Learning in Tunisia

Journal of Sustainable Agriculture and Environment, Volume 4, Issue 4, December 2025.
ABSTRACT Olive cultivation is a key agricultural activity in Mediterranean regions, yet its yield is highly sensitive to the impacts of climate change. Accurately predicting olive yield using optical remote sensing and data‐driven models remains a challenging task.

Multi‐Horizon Active Layer Thickness Prediction Across Circum‐Arctic Permafrost Regions Using Geospatial Machine Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Accurately predicting active layer thickness (ALT) is critical for assessing permafrost stability and mitigating risks to Arctic infrastructure, ecosystems, and communities. However, large‐scale ALT prediction remains challenging due to limited in situ observations and high spatial variability in environmental drivers.

Coseismic Slip and Early Rapid Afterslip of the 2025 MW 7.7 Myanmar Earthquake Constrained by Space‐Based Geodetic Observations

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract The 2025 destructive Myanmar earthquake ruptured the previously recognized seismic gap along the Sagaing fault, with the longest ever recorded surface ruptures (∼ ${\sim} $500 km). Here, we use SAR and optical images to characterize coseismic and early postseismic deformation of this event.

Rapid Methane Flux Estimation Combining MethaneSAT and Sentinel‐5P Observations: A Case Study of Turkmenistan

Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract Rapid estimation of high‐resolution (∼km), regional‐scale (∼104 km2) CH4 fluxes plays a critical role in supporting the Global Methane Pledge and guiding targeted mitigation strategies. This study presents a novel method that combines XCH4 observations from MethaneSAT and Sentinel‐5P to directly estimate CH4 fluxes without relying on chemical ...

Topography, Seed Dispersal, and Climate Change Reduce Future Habitat for an Endangered Tropical High‐Altitude Plant

Biological Diversity, Volume 2, Issue 2-3, Page 95-105, September 2025.
Combining topographic preferences of endangered high‐elevation Puya raimondii rosettes, seed dispersal distances, and future climate scenarios, we project habitat availability in the year 2100 in the Cordillera Blanca, Peru. We predict a significant decrease in occupied habitat patches, with almost complete loss for the +5°C climate change scenario ...

Accuracy Assessment of DEMs in Different Topographic Complexity Based on an Optimum Number of GCP Formulation and Error Propagation Analysis [PDF]

, 2020
One of the main concerns during digital elevation model (DEM) evaluation is the number of ground control points (GCP). Accordingly, in this paper, a new method is proposed for calculating the appropriate number of GCPs for DEM evaluation based on a ...
