LA VIA DELL'ACQUA

The case concerns La via dell’acqua, a public space project in Quartucciu, Sardinia, aimed at renaturalizing the Is Cungiaus River while addressing climate change challenges. The main issue revolves around transforming a formerly neglected area, including a wild landfill, into a sustainable ecosystem with flood mitigation strategies and habitats for native species. The project also introduces a climate shelter inspired by prehistoric architecture, serving as both a refuge from extreme heat and an educational space on climate change.

La via dell’acqua is a public space project combining architectural and landscape approaches. It is located in the south of the Italian island - Sardinia, more precisely in the town of Quartucciu on the Is Cungiaus River, once used for agricultural purposes. The river, currently regulated, is being renaturalized in the project by correcting the course and banks of the riverbed. Strategically placed natural barriers slow the flow of water, mitigate the effects of floods and enrich habitats for native animal species. Formerly neglected fields and a wild landfill will be revitalized. They will be transformed into vibrant habitats for native wildlife. Walking along the alleys, following the direction of the river's current, we are led along an educational path that presents humanity's relationship with nature evolving over the past centuries and shows us a plan for harmonious coexistence with it in the coming years. Since Sardinia is located in the Mediterranean zone and has record temperatures (48.2oC in July 2023) emphasizes the urgent need for action. The project also introduces the role of a climate shelter. Inspired by an Italian cave and prehistoric buildings from the Nuragic period, the underground structure protects against the increasing heat every year. Smoothly connected to the river, during periods of intense rainfall causing the water level to rise, it becomes a retention reservoir, reflecting the balance between functionality and aesthetics of the newly created architecture. This facility also serves an educational function. The exhibition informing visitors about the impact of climate change on humanity was entirely carved on the walls and ceiling of the building, so it will not be damaged by water flowing into the facility.
