Outline of Final Research Achievements

This study attempts to empirically clarify the historical changes in the Tohoku region, which was one of the iron production centers in the early modern period, especially the Sendai clan, using iron, forests, and sediment as keywords to link the region through the natural linkage of watersheds. We attempted to examine new perspectives and methods of regional history research, while keeping in mind the perspectives of watershed history and environmental history. In this region, increased iron production was promoted since the late 18th century, linked to climate change, and this brought environmental changes to the watershed, such as sediment discharge into rivers and reduction of forest resources, and also affected local society and policies.

日本近世史

Academic Significance and Societal Importance of the Research Achievements

鉄は文明の成立にとって不可欠なものである。日本列島の前近代社会においても、それは同様であった。ことに農業生産の発展を支えた鉄製農具や民衆的な流通に大きな影響力を持った銭の大量供給なども、鉄なしにはありえなかった。一方で、それは鉄の増産を促し、森林資源や原料たる砂鉄生産を起点とした河川への土砂流出などを介して、山‐川‐海からなる流域環境に大きな影響を与えることになった。本研究の意義は、近世東北地方を事例に、近世社会の生産力や経済の発展がもたらした地域環境への負荷とそれに対する対応の歴史を、鉄生産に視点を置きながら地域環境史の観点から捉え返した点にある。
