Irrigated fertile river osasises, surrounded by dry deserts
For more than 2000 years, agriculture is restricted to the river oasises, because all surrounding land is stone or sand desert nearly without precipitation. In addition, land was artificially irrigated since the middle Nazca period.
Water from the Andes rivers causes green valleys in the mid of naked hills and plateaus.
Many rural dwellings are poor.
Cotton and vegetables are cultivated.
Initial period (1500-800 v.Chr.)
Paracas period (800-200 v.Chr.)
Nazca period (200 v.Chr.-620 n.Chr.)
’middle horizon’ (620-1000 n.Chr.)
Development of settlement in the Río Palpa drainage (after B. Mächtle). Obviously the desert expands constantly. In spite of that settlement (red dots) is booming in the Nazca period, before it collapses after 600 AD.
Cerro Blanco, a sand formation situtated on the top of hills, was said by the ancient to be the origin of submerse water.

Puquio ’La Gobernadora’ combined from 3 photos, after Schreiber / Lancho Rojas
Between seepage and appearance of the Nazca river the submerse water stream is tapped by a lot of channels (puquios) which originate partly in the Nazca period. A puquio which begins submersely to the left (in the picture) opens gradually to the right.
