New LiDAR (Light Detection and Ranging) scans of the Beni region in the Bolivian Amazon have uncovered a vast and complex irrigation network built by pre-Columbian societies. The system consists of hundreds of kilometers of canals, raised fields, and artificial mounds, indicating a highly organized agricultural society that thrived in a challenging wetland environment. The scale of the network suggests a population much larger than previously estimated.
This 'anthropogenic landscape' demonstrates that ancient Amazonians actively engineered their environment to sustain large-scale farming. The research challenges the myth of the Amazon as a 'pristine' wilderness and provides a model for modern sustainable land use in tropical regions. Further ground surveys are planned to collect soil samples and date the canal segments.
