Abstract: Soil erosion and land degradation are critical environmental issues with significant implications for agriculture, biodiversity, and ecosystem services. Remote sensing and Geographic Information Systems (GIS) offer powerful tools for assessing these processes at various scales. This paper presents a comprehensive review of methodologies and techniques used in the assessment of soil erosion and land degradation utilizing remote sensing and GIS. It discusses the principles underlying these technologies, explores different approaches for mapping erosion-prone areas, quantifying soil loss rates, and identifying contributing factors to land degradation. The paper also highlights the advantages and limitations of remote sensing and GIS in soil erosion and land degradation assessment and provides insights into future research directions in this field.
Keywords: Soil erosion, Land degradation, Remote sensing, Geographic Information Systems (GIS), Mapping, Soil loss rates
