Collection description

The research investigates issues related to the territories of abandonment and waste, named Wasted Landscape, in urban and metropolitan fringes, as spatial transpositions of the outputs of the linear and unsustainable metabolic processes of the cities. The cause-effect analysis carried out with respect to their condition of marginality and degradation, as well as contamination of their environmental matrices, proposes a re-reading of them as potential and innovative resources of the urban planning project. In this regard, recognising the identity and strategic value of existing capital, the research aims to put the emphasis on regeneration and reclamation mechanisms to be applied in crisis contexts as essential materials of the city project. The research therefore, starting from a conventional concept of remediation, intends to investigate how a transition from sectoral environmental remediation approaches to integrated and multiscale intervention models can be made. In this line of research, reclamation is considered as a complex intervention that requires tools to identify eco-innovative, nature-based, and shared strategies and solutions. The main aim is to develop an integrated connection model between the objectives and actions of the urban project and the treatment of environmental issues through interscalar and intersectoral approaches capable of being internalized in the process of participatory laboratories on the model of Living Labs. These fertile interaction contexts, with the involvement of different stakeholders, including the end user, allow us to intercept regenerative solutions based on the assessment of impacts with respect to urban and landscape dimensions, but also social, economic, and cultural contexts of belonging. Placing the reclamation of Wasted Landscape in a circular and sustainable dimension means increasing the resilience and adaptability of the urban and territorial project of latent metropolitan contexts compared to the environmental pressures that affect them, as well as activating public-participation processes which are useful to imagine new economies for their recovery. The proposed change of perspective therefore shows a potential double consequence of the reclamation processes: operational, as possible and new regeneration vectors open to the landscape scale, and programmatic, as drivers of proactive changes in practice and in planning tools. The theoretical-analytic dimension, which underlines the critical aspects currently attributable to the rehabilitation interventions, together with the definition of tactical-operational strategies allow them to be overturned positively. The spatial transposition of the effects of this approach is in fact realised in new and regenerative landscape conformations aimed at unfolding collective benefit and social inclusivity.
