ResumoLand degradation (LD) for the people's livelihoods and climate is one of the key environmental concerns. In LD mapping, measurement, and monitoring at various space and time scales, geospatial technology plays an immense role. Rational synthesis of the role of remote sensing for LD assessments is presented in this chapter. Firstly, context information is given about LD meaning and the current evaluation frameworks. This is accompanied by a short analysis of the key satellite sensor variables used in LD analysis and characterization of the fields of operation of geospatial technology for LD evaluations. This chapter also supports multiscale and cross-scale LD evaluations that allow for application-oriented implementations and emphasize the need for on-site data validating LD maps focused on remotely sensed data.
