• A conspicuous lack of quantitative techniques to monitor medium- to large-scale soil erosion. • InSAR offers large-scale, continuous, and millimeter-level ground elevation deformation data. • InSAR technology-based soil erosion monitoring research has spanned all seven continents. • The application of InSAR technology in soil erosion studies holds significant potential. Soil erosion is a critical form of land degradation, posing a significant threat to soil health and ecosystem productivity. Accurate monitoring of soil erosion is essential for robustly estimating erosion rates to better plan and develop effective mitigation management strategies. While there have been extensive studies and remarkable progress, existing soil erosion monitoring methods mainly focus on disparate spatial scales, ranging from point and plot scales to slope, watershed, and regional levels. The absence of quantitative techniques for monitoring soil erosion at medium to large scales represent a significant impediment to characterizing and understanding its spatiotemporal dynamics. This study aims to provide a comprehensive review of existing soil erosion monitoring methods and to investigate the potential of Interferometric Synthetic Aperture Radar (InSAR) technology to address this critical gap. A comprehensive analysis of soil erosion processes and monitoring approaches is presented, evaluating the applicability of InSAR for monitoring large-scale soil erosion. Our analysis reveals that over 50 %...
