Reconstructed Yanamayo canals have been shown to reduce frost occurrence in test plots, confirming ancient design efficacy.
The Yanamayo canal network, constructed between 500 and 1000 CE near Tiwanaku, demonstrates precise water management integrated with raised-field agriculture. Channels captured runoff from seasonal rains and snowmelt, directing water to waru waru fields. Archaeological surveys confirm systematic branching and leveling to optimize distribution. Experiments with reconstructed canals indicate improved soil moisture and reduced frost risk. Maintenance of the network required coordinated labor and administrative oversight. The system reflects understanding of hydrology and local climate. Water control enhanced crop yields of potatoes, quinoa, and other tubers. The design illustrates how Tiwanaku combined environmental adaptation with engineering for food security. Continuous upkeep ensured long-term sustainability of high-altitude agriculture.
