[H-QR05] Quaternary, Diachronic dynamics of human-environment interactions

Thu. May 29, 2025 10:45 AM - 12:15 PM 101 (International Conference Hall, Makuhari Messe)

convener:Masaaki Shirai(Tokyo Metropolitan University), Yusuke Yokoyama(Atmosphere and Ocean Research Institute, University of Tokyo), Takashi Azuma(National Institute of Advanced Industrial Science and Technology), Yasufumi Satoguchi(Lake Biwa Museum), Chairperson:Takeshige Ishiwa(National Institute of Polar Research), Fumikatsu NISHIZAWA(Kanagawa Prefectural Museum of Natural History)

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.
