[H-QR04] Quaternary, Diachronic dynamics of human-environment interactions

Sat. Jun 5, 2021 9:00 AM - 10:30 AM Ch.16 (Zoom Room 16)

convener:Mamoru Koarai(Earth Science course, College of Science, Ibaraki University), Yusuke Yokoyama(Atmosphere and Ocean Research Institute, University of Tokyo), Koji Okumura(Graduate School of Letters, Hiroshima University), Yasufumi Satoguchi(Lake Biwa Museum), Chairperson:Mamoru Koarai(Earth Science course, College of Science, Ibaraki University), Tsutomu Nakazawa(Geological Survey of Japan, AIST)

Humans have attained their specific development by indigenous cultures and evolved through environmental adaptation. The session raises issues of human-environmental interactions, views from diverse changes of climate, ocean, land and biota having made striking influence on humans. It welcomes various fields from human-environment change and their chronometric dating among Quaternary disciplines.
