From Psychology of Sustainability to Sustainability of Urban Spaces: Promoting a Primary Prevention Approach for Well-Being in the Healthy City Designing. A Waterfront Case Study in Livorno

One of the main objectives of contemporary society and international research is to improve the physical and psychological health and well-being of the population, especially within the urban space. An effective approach to address this complex issue must necessarily be trans-disciplinary, and must be framed in the broader perspective of the Science of Sustainability, in particular the Psychology of Sustainability and Sustainable Development, as a frame of reference. The study shows the first results of research, in terms of methodology and qualitative analysis, with the following objectives—identification of the criteria for intervention for a healthy city design, with particular attention to the psychological, architectural, and construction aspects, and an initial verification of these criteria, through a case study consisting of a section of the city’s waterfront, in the city of Livorno. This case study has enabled, both, the definition of an innovative design and implementation of solutions, for the correct use, accessibility, and management of spaces. It provides the first evaluation of a possible digital analyses of a waterfront, before and after intervention; and highlights the potential and the critical aspects of the process of recovery and re-appropriation of an urban space, for a new social life, within it.
