Waru waru is a type of raised-field agriculture developed by pre-Hispanic peoples of the Andes region of South America, practiced from Ecuador to Bolivia and also known by the Spanish name camellones. The system alternates parallel canals with raised planting beds built near water sources, using nutrient-rich soil drawn from aquatic plants and organic material as fertilizer; the water in the canals absorbs solar radiation that helps protect the raised beds from frost while also supplying irrigation, together lengthening the growing season and increasing yields. Functionally similar raised-field techniques have developed independently in other parts of the world.
