The book "Use of the Normalized Difference Vegetation Index (NDVI) to Assess Land Degradation at Multiple Scales" offers a comprehensive analysis of the application of the Normalized Difference Vegetation Index (NDVI) for assessing land degradation. It explores the scientific foundations of using remote sensing data, particularly NDVI, and its relevance for various applications, including the resilience of agro-ecosystems. The authors draw on a wide range of studies from the scientific literature as well as interviews with leading experts in the field. The book addresses various topics related to land degradation, such as land use changes, drought monitoring, desertification processes, and the impact of vegetation fires. Additionally, it discusses the limitations of using NDVI for assessing land degradation and future application possibilities. The findings indicate that NDVI data are strongly correlated with important biophysical vegetation properties that are significant for studying land degradation and the resilience of agro-ecosystems.
