Abstract

The qanat, a timeless testament to human ingenuity, emerged on the arid Persian Plateau around three millennia ago as a sustainable solution to water scarcity. This technique channels water from aquifers using gravity through gently sloping sub-horizontal tunnels, avoiding over-extraction and ensuring a delicate balance between human needs and environmental preservation. By naturally regulating water flow according to aquifer levels, qanats prevent excessive depletion, serving as a model for sustainable water resource management. This study explores the fascinating journey of qanats, their geographical spread, historical evolution and enduring relevance. We highlight their adaptability to diverse environments, their role in fostering cultural continuity and their potential to address contemporary water challenges. By revisiting this ancient marvel, we uncover valuable lessons for contemporary water management systems worldwide.
