Ventilated granaries at Yanatari preserved tubers for up to a year, supporting population stability in high-altitude conditions.
Yanatari storage facilities, active between 500 and 900 CE, consisted of stone foundations with adobe superstructures and ventilated interiors to maintain temperature and humidity. Granaries stored potatoes, quinoa, and other highland crops, ensuring food availability during lean periods. Archaeological remains show standardized construction dimensions for multiple units within compounds. Strategic placement near raised-field agriculture facilitated efficient distribution. The design mitigated spoilage from frost, pests, and moisture. Controlled ventilation and elevation prevented rot. Coordination of storage reflected administrative planning and communal labor. Maintaining surplus allowed Tiwanaku urban centers and ceremonial activities to function without interruption despite environmental variability.
