The theme «The City and Water: Between Climate Change and Languages» was at the heart of an international symposium held on Tuesday in Marrakech, bringing together professors, researchers, engineers, and students. Organized by the National School of Architecture of Marrakech, this scientific event is part of a series of international meetings hosted by the institution and aligns with the momentum surrounding the upcoming 19th World Water Congress, set to take place in the ochre city from December 1 to 5. The symposium was also held in partnership with the Department of Energy, Land, and Water Engineering at the University of Pisa and the Department of Architecture and Environment at the University of Naples. Its aim was to foster the exchange of expertise and experiences between Italian academics and engineers and their Moroccan counterparts in areas related to water, urban planning, and the interplay between architecture and water in the context of today's environmental and urban challenges. Speakers highlighted the importance of scientific cooperation between friendly nations with strong experience in the sustainable management of this vital resource. They also presented key projects aimed at developing a new generation of master plans that place water at the center of urban planning. Key topics addressed during the meeting included water-related architectural techniques, water systems in historic Moroccan cities such as Fez and Marrakech, traditional irrigation methods like khettaras, historic gardens, and water management in medinas and islands surrounded by water.
