Rainfall is scarce, often falling below 150 mm annually, making conventional farming nearly impossible. Yet, across this ancient landscape, lines of circular earth mounds stretch for miles, tracing an invisible path. These markers are the vertical shafts of the qanat system, an engineering masterpiece that transformed desert regions into vibrant oases for millennia. This ingenious, gravity-fed network accessed deep groundwater and delivered it to the surface, sustaining vast agricultural civilizations. The qanat is more than a hydraulic device; it is a profound testament to sustainable human ingenuity and community resilience in the face of environmental extremity. ...
