Human-centred indicators (HCI) to regenerate vulnerable cultural heritage and landscape towards a circular city: From the Bronx (NY) to Ercolano (IT)

Many cities globally are incorporating the circular economy model into their development strategies to start transitioning as "circular cities" towards the implementation of human-centred development. In many of them, one of the major challenges is represented by the large presence of cultural heritage being in a state of degradation, abandonment and underutilization, which determines waste conditions not only at physical/spatial level but also at economic level (the presence of subsistence economies) and at a social and cultural level (marginalization phenomena and high rates of unemployment). The perspective of circular economy allows rethinking these waste conditions as an opportunity to reactivate virtuous circuits capable of promoting sustainable development focused on human needs. In this perspective, the paper aims to demonstrate both the importance of participatory approaches in guiding circular and human-centred regeneration processes and of identifying evaluation tools capable of integrating the human and ecological dimension with the economic one. With this aim, a circular methodology is proposed and experimented with in Ercolano (Italy) and in the Bronx (New York), in which the adoption of a participatory approach was central in all phases of regeneration processes, from the identification and analysis of vulnerabilities and waste conditions to the definition of a strategy capable of transforming these limitations into opportunities. A first result is the elaboration of a framework of "Human-Centred Indicators" to monitor and support the adoption of the circular economy strategy toward implementing the "human-centred city".
