Pre-Columbian agriculture in the Bolivian Lowlands: Construction history and management of raised fields in Bermeo

Dating shows intermittent raised-field use in a few construction events

what the source states

"…radiocarbon and optically stimulated luminescence dating, show that the raised fields were in intermittent use since as early as AD 570–770… The data suggests that raised fields were built during a few separate construction events, probably linked to periods of more frequent and severe floods. The study challenges the most widely accepted theory that suggests that pre-Columbians were able to cultivate these fields on a continuous basis…"
