Lisbon is one of the pilot study cases in the "Cool Noons" project, scientifically coordinated in Portugal by researchers from the University of Coimbra. The project aims to establish "cool paths" in cities through "routes where the presence of gardens and shade provides a more pleasant experience for residents and tourists," the University of Coimbra (UC) revealed in a statement.

"Cool Noons" is taking place in four other cities in the Mediterranean region: Budva (Montenegro), Dubrovnik (Croatia), Imola (Italy), and Marseille (France).

According to the team, led by Ana Maria Caldeira, a researcher at the Center for Geography and Spatial Planning Studies (CEGOT), "cities face a risky scenario for tourism and the quality of urban life, particularly outdoor activities such as tourism and leisure activities," due to "increasingly intense and frequent heat waves."

The study of the thermal comfort of residents and visitors, particularly in the summer months, aims to implement "effective measures to cool the most frequently used urban routes, especially during the hottest hours of the day, through innovative, nature-based solutions," the researchers added.

In Lisbon, the UC team is collaborating with the City Council to study the impact of the cool paths selected by the municipality and "to test cooling solutions that will soon begin in Alvalade and Monsanto."

Researchers are collecting data on the impacts of air temperature on city visitors and the benefits of these "cool paths" for tourists and residents, before coordinating a scientific evaluation of the potential benefits of the planned interventions.

In addition to identifying cooler routes, these routes in the participating cities are creating pedestrian-free areas, installing shade canopies, planting trees, and installing picnic tables with sun protection and planters.

At the Dubrovnik Maritime Museum, an augmented reality app is being tested to attract visitors to refreshed spaces as a way to combat not only the heat but also congestion at these cities' central attractions.

According to the statement, the UC team "hopes that this project can contribute to thinking about the future of cities and their adaptation to climate change, especially in urban planning and development initiatives."

The "Cool Noons" project is funded with over €1.8 million by the European Commission's Interreg Euro-MED program, led by the Agency for Sustainable Mediterranean Cities and Territories (Agence des Villes et Territoires Méditerranéens Durables), bringing together nine partners from five countries.

The project (available at https://coolnoons.interreg-euro-med.eu/) will run until September 2026.
