We analyzed changes in the relationship between geo-environment and agricultural land development around the central Jamuna (Brahmaputra) River, central Bangladesh. Based on sedimentary facies analysis and AMS radiocarbon dating, some conclusions are as follows: (1) Natural levees along the Jamuna River formed until ca. 12 to 11 k cal yrs BP; (2) Homesteads (bari-bhiti) were repaired by public works (mati-kata) following some flood events; (3) Paddy fields and homesteads were created since ca. 1.3 k cal yrs BP around central Bangladesh (central Bengal Delta).
