Elements of Evolution of the Relations Between the Soils and the Climate in the Territory Between Prut and Nistru in the Context of Climatic Changes and Natural - Antropic Pedogenesis

Abstract

The evolution of climate during the seventy-year cycle (1946-2016) led to the shaping, in the region, of two parallel trends of the evolution of the soil cover: a) in the sense of aridization; b) in the sense of humidification. These are due to the contouring of an alternation of drought and humid and relatively damp years in the 11-year climate cycle. According to calculations, 5 of them are humid or relatively damp and 6 are dry or relatively dry. Research shows that the climatic environment in the phase of modification leads to the simultaneous development of processes of both aridization of several spaces and hydromorphism of other. This situation shows different stability of the soil cover components in the region to climate change under natural-anthropogenic chernozem conditions. This particularity of soil development is to be taken into account both in pedological studies and in the framework of Regional Strategies and Programs for Adaptation to Climate Change.
