The Supe Valley lies in one of the driest coastal regions of Peru, making irrigation essential for agriculture.
The Supe Valley provided fertile floodplains nourished by seasonal Andean runoff. Archaeological surveys reveal irrigation canals that supported cotton and squash cultivation. These systems date to the early third millennium BCE. Controlled water distribution enabled consistent agricultural output in an otherwise arid coastal region. Stable production underwrote population concentration at Caral and neighboring sites. Irrigation management required cooperative labor and oversight. Environmental adaptation preceded monument construction. Water governance shaped urban foundations.

Irrigation infrastructure demonstrates early administrative coordination. Shared water management fosters institutional authority. Agricultural reliability supports surplus accumulation and craft specialization. The Norte Chico example highlights engineering without metal tools. Institutional resilience depends on environmental mastery. Hydrology becomes policy. Control of water stabilizes power.
For farmers, canal maintenance structured communal obligation. Seasonal flows dictated planting cycles and ritual timing. The psychological trust in engineered systems fostered stability. Yet dependence on river patterns also introduced vulnerability. The irony is that the same water enabling growth demanded constant cooperation. Survival required coordination.
