[MIS22-03] Exploring for climate proxy records based on historical documents for Japanese history
Keywords:Japanese history, Paleoclimatology, Historical documents, Tree rings
In this study, we explored the relationship between climate and rice productivity by utilizing precipitation reconstructed from tree rings and historical document. Specifically, we extract multiple years with extremely high or low amounts of precipitation in the Edo period using the tree-ring data. Descriptions related to climate or agricultural yields are also collected from historical documents that originate from multiple sites over Japan. Based on these data, we explore the impact of climate changes on agricultural yields in different regions and periods. Also, we observe the association between climate described by humans and tree-ring-based climate, in order to explore for climate proxy records based on historical documents.
