| Abstract: |
The northern Khorat Plateau has long been the focus of archaeological debate in Thai prehistory. The timing of the initial settlement of the region and the relationship between early communities and the environment, particularly in regard to rice cultivation, remains substantially unresolved. Despite this, there have been few attempts to provide a detailed environmental context. Palynological data from Nong Han Kumphawapi, a lake site in Sakon Nakhon basin, northeast Thailand, indicate a period of forest disturbance and increased fire frequency from c. 6400-6600 years BP (Before Present). While it is impossible to be unequivocal regarding the cause of this disturbance, palaeoclimatic data from the region are difficult to reconcile with the patterns of vegetation change indicated here. Widespread burning and forest exploitation by human populations is the preferred interpretation at present.
