With special emphasis on the legacies inherited from ancient Persia, one of the most brilliant water civilizations in history, “Water & City” includes case studies from a variety of countries in the Middle East, Europe and North Africa. The book originates in a research workshop held in 2018 in the desert city of Yazd, known as the cradle of millenary qanat technologies in the world. Among the learnings from this pioneering cross disciplinary experience, it shows that combining heritage and innovation, tradition and technology, in future architectural and urban design projects is the only path towards re-inventing the integrative role played by water.
