| Research Abstract |
In this study, dated charcoal and buried humic soil layers (including humus materials), both of which are evidence of forest fires indicate past deforestation and agricultural land development by tribe migration around Eastern Himalayas (eastern Bhutan to Arunachal Pradesh, north-eastern India). Around the eastern Bhutan to Arunachal Pradesh area, human impacts such as population growth by tribe migration may have accelerated environmental and agricultural changes after ca. 2 ka yrs BP, mainly. Relatively intense agricultural land formation that occurred since ca. 1 ka yrs BP (mainly after ca. 0.5 ka BP) was due to tribe migration. On the other hand, in Bengal delta (Bangladesh), we analyzed the changes of relationship between geo-environment and agricultural land development around the central Jamuna (Brahmaputra) River, central Bangladesh. Based on sedimentary facies analysis and AMS radiocarbon dates, some conclusions are as follows: Natural levee along the Jamuna river have formed until ca. 12 to 11 k cal yrs BP; Homstead (bari-bhiti) were repaired by public works (mati-kata) from some flood events; Paddy fields and homestead were created since ca. 1.3 k cal yrs BP around the central Bangladesh (central Bengal delta) .
