Soil represents a three phase system and forms a major component of the Earth’s surface providing medium or crops cultivation. Each year soil quality and health is getting declined abruptly through naturally as well as anthropogenic activities. Especially in hilly areas, soils are more prone to erosion due to topographical nature. The assessment of soil erosion helps us to identify the soil erosion susceptible areas enable proper soil management and supports policymakers in developing effective policy frameworks, particularly in hilly regions. The advancement in remote sensing had made human work easier and more precise. By using these technologies, it is possible to evaluate the degree of erosion and interpret the result. Also, remote sensing and GIS technology proves to be a valuable tool in developing suitable models through utilization of advanced features of data storage and management, interpretation, and display of spatial data to assess the erosion. It catalogs commonly used remote sensing data sources and introduces innovative methodologies for detecting soil-erosion-related information utilizing remote sensing data. Moreover, this chapter highlights the potential use of Remote Sensing (RS), Geographic Information System (GIS), and Unmanned Aerial Vehicle (UAV) for assessing soil erosion through spectrum-based identification, accurate quantification of erosion-prone areas, and the application of various spatial analysis techniques. Their combined use offers a comprehensive and efficient approach for monitoring soil degradation, particularly in diverse and inaccessible terrains.
