Polarimetric PALSAR System Model Assessment and Calibration

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
Polarimetric PALSAR system parameters are assessed using data sets collected over various calibration sites. The data collected over the Amazonian forest permits validating the zero Faraday rotation hypotheses near the equator. The analysis of the Amazonian forest data and the response of the corner reflectors deployed during the PALSAR acquisitions ...

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

Environmental heterogeneity and spatial variation mediates plant diversity and ecosystem stability in mountain ecosystems of the Mediterranean Andes

Ecography, Volume 2026, Issue 4, April 2026.
Globally, mountains are highly diverse ecosystems that serve as natural laboratories for testing ecological theories, while providing vital ecosystem services. Their biodiversity arises from the interaction between elevational gradients and topographic complexity, which generate strong variation in environmental conditions across short spatial scales ...

Assessing the Potential for Agroforestry in Pokhara, Nepal: An Investigation of the Decline of Agricultural Land Use Along a Rural–Urban Gradient and Land Suitability Analysis

Plant-Environment Interactions, Volume 7, Issue 2, April 2026.
ABSTRACT An agroforestry program is often considered an ameliorative option for land utilization, agricultural production, and environmental sustainability. However, land suitability for agroforestry is not always readily known to farmers and local policy planners.

Interlinked Dynamics of Rice Cultivation Intensity and Ground Subsidence: Spatio‐Temporal Insights Into Water Resource Implications From Multi‐Year Spaceborne SAR Analysis

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Sustainable rice cultivation is vital to meet global food demands, particularly in regions relying on groundwater for irrigation. Over‐pumping, however, can cause significant ground subsidence, threatening both infrastructure and agricultural sustainability.

Harnessing nature‐based solutions in modified tropical peatland to benefit biodiversity

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
Our findings demonstrate that well‐designed protection–production NbS schemes in tropical peat swamps can deliver joint climate and biodiversity benefits, provided that governance safeguards core forests while improving habitat quality in production zones.
