Reconstructing the anthropogenic aridization of landscapes in antiquity and in the Middle Ages from isotopic data

The methods from geochemistry of stable isotopes, and spore-pollen and paleopedological data on climate humidification variation have been used to reveal three time intervals: the beginning of the 4th millennium BC, and the 3rd-4th and 8th-14th centuries AD when the indices of local climate changes showed oppositely directed tendencies, which suggests a contribution of the anthropogenic factor (pasture digression) to the modification of vegetation of the landscapes under investigation.
