Approximately 2.000 years ago, in the pre-Columbian times, the inhabitants of Nazca developed a system of subterranean aqueducts to water the dry parts of the valley, which were lacking superficial water. The men of the Nazca culture could also combat the long droughts, which are existent in the valley of Nazca.This watering system is unique in Peru and probably in the entire world. Although the years have passed and there have been frequent Telluric movements in this zone, in the region of Nazca are still existing more than 30 subterranean canals, which are still used today by the farmers of the valley. These predominantly sow cotton, corn, beans, pallares and potatoes, as well as a variety of fruits.
