| Outline of Final Research Achievements |
In this study, dated charcoal and buried humic soil layers, both of which are evidence of forest fires indicate past deforestation and agricultural land development by tribe migration around Eastern Himalayas. Around the Southern Tibet area and eastern Nepal to Arunachal Pradesh area, human impacts such as population growth by tribe migration may have accelerated environmental and agricultural changes after ca. 2 ka BP, mainly.
In Bengal and western Japan alluvial Lowland , we analyzed the changes of relationship between geo-environment and agricultural land development around the central Jamuna (Brahmaputra) River, central Bangladesh and Asahigawa River, Okayama Lowland. Based on sedimentary facies analysis and AMS radiocarbon dates, some conclusions are as follows: (1) Natural levee along the Jamuna river have formed until ca. 12 to 11 k cal yrs BP; (2) Around Lowland of Western Japan, Natural levee a have formed until ca. 13 k cal yrs BP.
