Abstract
Communicated by Academician Aleksey V. Matveev
The reconstruction of environmental changes in the southeast of Belarus during the last 14700 cal. BP is based on the results of palynological, radiocarbon, isotope and lithological studies of Lake Staroje deposits. Climatic fluctuations, fires and human activities played a significant role in the transformation of the vegetation cover. The beginning of the lacustrine sedimentation was dated circa 16000 cal. BP. The intensification of erosion processes on the water catchment area was marked by an increase in the mineral material flow into the lake. These events have a positive correlation with the climate cooling and humidity phases in the Late Glacial and Early Holocene, and in the Late Holocene with anthropogenic impact stages. The traces of the episodic human activity were dated to 5800 cal. BP, while the expansion of farming and pasturing areas began at 3000 cal. BP Currently the consequences of human activities (including drainage of bogs) are reflected in the treeless landscapes adjacent to the lake.
Supporting agencies: The research was carried out with financial support State Program of Scientific Research “Nature Management and Ecology”, task 1.21. Reconstructions of fire frequencies and forest coverage were performed by E. Yu. Novenko with financial support of Russian Science Foundation (Grant 16-17-10045)
