Designing green corridors in the historic centre of Bologna: a replicable model for urban regeneration through Nature-Based Solutions (NBS)

The design of the Green Corridor on Via Cesare Boldrini in Bologna addresses the need to transform the urban environment into a more sustainable, accessible, and resilient space, prioritizing citizens over vehicles and fostering a balance between green infrastructure and urban activity. This research proposes a replicable model for urban regeneration through Nature-Based Solutions (NBS), aiming to enhance environmental quality and create a healthier urban ecosystem. NBS play a key role in the regeneration of public spaces by improving ecological connectivity, reducing heat island effects, and promoting biodiversity in the urban context. The methodology adopted for this research began with an initial historical consultation to understand the context and evolution of the area, followed by a deep dive into the essential concepts of Nature-Based Solutions and their application to urban environments. Key references were reviewed to explore best practices and case studies. Based on this foundational research, a design proposal was developed, aligning the green corridor concept with Bologna’s urban fabric and historical context, while integrating sustainable design strategies, such as Sustainablo Urban Infrastructure, permeable pavements and green urban furniture. Key elements of the design include: * Expansion of green infrastructure to balance urban and natural dynamics. * Reduction of vehicular traffic to create safer and more accessible public spaces. * Reactivation of abandoned buildings into cultural and social hubs. * Integration of urban gardens and meeting areas to encourage social participation. * Revitalization of Piazza XX Settembre, reinforcing its role as a cultural and historical landmark. The impact of the Green Corridor extends beyond ecological improvements, aiming to reduce vehicular traffic and improve social cohesion. The project contributes to the creation of a more livable and equitable urban space, fostering resilience in a historically rich city.
