The landscapes of the Volga-Oka right bank in Nyzhniy Novgorod region are considerably transformed by human activity. Our geoarchaeological study allowed us to determine the beginning of anthropogenic impact on landscapes, which caused their catastrophic changes. Since the 14th century and sharply from the 18th century, accelerated anthropogenic soil erosion manifested itself. The watersheds and slopes decreased by 40-60 cm. The thickness of agrogenic sediments in the bottom of ravines is more than 4 m. The ecological disaster is associated with the superposition of an anthropogenic factor (deforestation and plowing of lands) on an unfavorable natural climate change. The period under study is on the wet and cool phase of the Little Ice Age.
