A Deduced Method for Assessing Safety and Security Perception: Case Study of Biblioteca Degli Alberi Park in Milan, Italy

Urban greening initiatives have taken many innovative forms over time, from large urban parks planning and preservation to ecosystem-based approaches such as Nature-based Solutions (NBS). Even though implementing NBS and vegetation are accompanied mainly by positive impacts, a considerable body of scientific evidence demonstrates the negative consequences of urban green areas on the subject of reducing safety and safety perception in terms of impacts on visibility and fear of crime. Considering vegetation as a critical element of the urban landscape, identifying the safety perception while implementing greenery interventions requires a deep study of their characteristics about space functionality. This chapter aims to implement a methodology for assessing the safety and security perception of urban green spaces. The methodology is based on safety and security principles and indicators selected from an extensive literature review of scientific research and design guidelines for safer cities and relying in particular on the concept of Crime Prevention Through Environmental Design (CPTED). Assembling data regarding the case study’s safety perception is conducted through a survey-based approach and an online questionnaire. Case-study application for testing the methodology was the Biblioteca degli Alberi di Milano (BAM) park in Milan, Italy.
