New approach in studying dynamics of desertification areas is proposed for the case of North West Caspian region. Desertification areas of natural and anthropogenic origin, with aridisation increased by albedo - precipitation feedback, are identified. Difference in dynamics of desertification areas is detected by comparison data for periods 2005-2009 and 2000-2004 years. Chernozemelsky (Black Soil) area is decreased, while desertification areas in Astrakhan region and Western Kazakhstan are increased and merged.
Keywords: dry lands, desertification, aridization, degradation of land, surface albedo, surface temperature, mesoscale albedo-precipitation feedback
