A Framework Research: Investigating Different Methods and Solutions to Map Built Heritage at Risk Through Participatory and Crowd Actions

The conservation of built heritage is a critical issue, concerning the evolving urban landscapes, potential threats to historical heritage, and the different stresses that expose heritage to risk. The present paper focuses on the upcoming theme of perceived risk, exploring the suitable and fundamental role of specific and promising participatory representation tools, such as community maps, crowd mapping, and video mapping, in empowering communities and facilitating informed decision-making processes toward risk management and mitigation. This contribution underlines the existing challenge of implementing and integrating scientific knowledge with local and perceived knowledge about risk exposure. Therefore, the above-mentioned participative tools are discussed, compared, and proposed as methods to fill the gap between the recognized and perceived risk, underlying their usefulness and contribution to risk evaluation within a comprehensive framework, including the dimension of the perceived risk. These methodologies are designed to serve citizens as users of the surrounding space and the primary individuals expressing individual perceptions of risk. They also cater to expert technicians responsible for implementing these methodologies. Lastly, they aim to support policymakers or decision-makers in making decisions ideally informed by these experiences and the results achieved applying these methodologies.
