3. History of human-plants relationship

(SS29) Use and management of plant resources in prehistoric periods in East Asia

Purpose: Human interaction with plant resources in prehistoric periods has been clarified dramatically in Japan and adjacent areas during the last ten years. We now know that the people in those periods were not plain hunter-gathers, but did manage plants resources around settlements and used them variously. In this symposium, we review the recent research results mainly carried out in Japan and deal with relevant environmental changes and use of various plant materials including timber, fruits, seeds, tubers, fibers, and lacquer, also touching upon introduction of plants from adjacent areas. Besides these reviews, we would like to present prospects for future research including topics such as identification of origins of plants and plant materials.

(SS31) Palynological evidence of past traditional farming systems and pastoralism

Purpose: Since the last two decades Non-Pollen-Palynomorphs (NPPs) get increased attention by Quaternary palynologists due to their ubiquity in all kind of habitats and their abundance in different sediment types, where they sometimes exceed the total number of pollen and spores. Algal cysts, fungal spores, trichomes, parasite eggs and/or zoological remains such as Neorhabdocoela eggs, among others, do therefore greatly add to our understanding on the evolution of former ecosystems worldwide. Together with classical palynological studies using pollen and cryptogam spores, NPP-microfossils such as spores from coprophilous fungi or nutrient indicators such as cyanobacteria and dinoflagelate cysts clearly add to our knowledge on past traditional farming systems and pastoralism, and may in turn – together with other palynological methods and proxies to be discussed and presented during this IPC session – help disentangling plant and animal diversity changes due to climatic change or human impact.

(SS35) Environmental and cultural dynamics of the last 21,000 years,with emphasis on prehistorical agriculture in East Asia and other places of the world

Purpose: It is assumed that global Neolithic culture including original agriculture was generally formed some 12,000-10,000 years ago. The global climate of the last 21,000 years exhibits dramatic changes and abrupt events. It incepted with the end of the latest glaciations, and simultaneously with the transition between the Paleolithic and the Neolithic, when culture of a hunting-gathering mode tended to qualitatively change into an agricultural society. This session aims to present new developments to build an interdisciplinary synthesis for environmental and cultural dynamics, integrated cultural contexts, and high-resolution climatic and vegetation frameworks. This session will specially focus on some major climatic events, such as the Younger Dryas, the Holocene Megathermal, providing evidence for changes in environments, ecosystems and others that affected the regional development of agriculture.
