Puquios: The Nasca Response to Water Shortage

In this chapter, we provide an overview on the state of the art of the investigations conducted up to now on the ancient Nasca filtration galleries, locally known as puquios. They are located in the three valleys of the Nasca, Taruga, and Las Trancas rivers. The technological characteristics of puquios, along with the main archaeological issues still open today such as, for example, the dating and potential relationships between puquios and the Nasca Lines, are briefly summarized. Finally, outputs from satellite-based investigations along with a brief overview on the location of the existing puquios, their current conditions, and management issues are provided.
