The concept of modern desertification’s climatic component in arid key regions in Eurasia and North Africa is proved in the monograph ‘Climate Desertification’ (Zolotokrylin, 2003). This concept explains the nature of climatic desertification and identifies its main peculiarities. Desertification means interaction between aridization and drylands degradation, with feedbacks in ‘arid territory-atmosphere’ system. Climatic aridization means refers not only to degraded territory’s atmospheric humidification reduce, but meso-scale processes of heat exchange between this territory and atmosphere boundary layers as well. In case of such heat exchange, aridization sustained by positive ‘albedo-precipitation’ feedback. This positive feedback based on negative correlation between degraded surface’s albedo and the temperature. The concept is based on the ability to quickly restore degraded dryland ecosystems with favorable climate effects. Later, it independently became the basis of a new paradigm of desertification, developed in the work "Dryland Opportunities. A new paradigm for people, ecosystems and development "(Mortimore, 2009), instead of the supported UNCCD degradation paradigm.
