NATURE-BASED SOLUTIONS ENFORCEMENT OVER ROAD PROFILES TO MITIGATE THE IMPACT OF CLIMATE CHANGE. A TACTICAL CASE STUDY IN TURIN'S URBAN AREA

The climate vulnerability in the urban areas of Turin is currently facing an unfavorable increase. Research has shown the increase in temperatures and the amount of rain intensity in the urban areas of Turin and the expected projections confirm a deterioration in the climatic conditions in future years. This study aims to define the feasibility of the road profile as a suitable field of intervention to implement NBS as tools for mitigating and reducing the climate vulnerability in the urban areas of Turin. The methodology applied was based on a systematic review of international and local cases of urban interventions focused on mitigation and reduction of climate vulnerabilities in urban contexts and always of the public space and the street as action field. Additionally using a standardized methodology, each case study was compared in qualitative and quantitative terms. Moreover, several interviews were conducted to experts and actors of the urban sphere of Turin to know their point of view regarding the public space and the street as the scenario for urban intervention regarding the theoretical concepts already studied. A preliminary design was carried out in the street section of two urban zones of Turin that undergo with the most relevant environmental risks such as high air pollution and high land superficial temperature. The study carried out took into consideration the current condition of the street in terms of the infiltration capacity and physical-environmental conditions. The design proposal and its respective analysis demonstrated that by the arrangement and new distribution of the street components the NBS could be implemented in a replicable typology over the street profile over certain conditions to assure their feasibility. The Mitigation strategies applied, and the spatial quality of the new street profile showed an improvement in increasing ecosystem services and enlarging and improving public space conditions, promoting, and enforcing the use of public spaces by the community as well as the enforcement of alternative and soft mobility methods.
