Desertification/Land degradation maps have been created for the Southern and Eastern Pre-Aral region and drought belt of Russian Federation on the base of new methodology. The land-scape maps created during satellite imagery processing were the contour base of desertification maps. Maps present the following features of the desertification phenomenon: man-induced and natural causes of desertification, main trends of land degradation and there degree, rate and depth (capacity of ecosystems rehabilitation). The model studies at the mentions regions provides a possibility to elaborate approaches to automatic procedures for desertification mapping at different scales to be used as scientific base for desertification monitoring
