Pre-Columbian fire and water management in Bolivia

Examining sediment cores from the Quinato wetland in Bolivia, researchers found that beginning at least 3,500 years ago, pre-Columbian societies used fire and hydrological engineering to transform the landscape of southwestern Amazonia, which would later be altered by the arrival of cattle and new technologies from Jesuit missions in the 17th century; the findings suggest that although precipitation increased during the mid- to late Holocene, the current landscape of southwestern Amazonia was shaped by hunting, farming, and fishing practices, according to the authors.
