This study is an effort to adapt the general principles, methodological tools, and equations of a widely used Mediterranean desertification and land use approach (MEDALUS approach) in order to detect environmental sensitive areas susceptible for land degradation in Cyprus. For this scope, different remote sensed data and products (Landsat multispectral imagery and ASTER Digital Elevation Model) were used as well as demographic information, taken from the Socioeconomic Data and Applications Center. Four quality indices were calculated (Climate Quality Index, Demographic Index, Soil Quality Index, and Vegetation Quality Index) and combined in order to provide at final stage, the Environmental Sensitivity Area Index (ESAI) with which the environmental status is described. The use of remote sensed data of 30‐m spatial resolution and the calculation of different indices to extract the environmental stress at regional scale can be considered as innovative characteristics of this study. According to this ESAI, it was found that 9.68% of the Cyprus Island is at environmental risk, strictly related to the land degradation potential. The spatial distribution of the ESAI values shows that the environmental risk is most significant in Paphos district and Limassol, following the Larnaca and the Famagusta districts. Nicosia and Kyrenia districts are found slightly less problematic. In addition, large parts of Troodos Mountain (especially in its low altitudes), which is one of the most vegetated areas of the Island, seem to be at notable environmental stress.
