The challenge of climate change is the most important issue of this time because of its environmental, economic and social impacts.
The circular economy model is here proposed as the general model of this World Cities Day celebration. This circular model is necessary today to face the climate change impacts. It can improve the promotion of a Better Urban Future, more inclusive and more ecologically sustainable.
How (metropolitan) cities can become more resilient adopting the circular model organization? Which strategies? Which technologies?
New perspectives are also required because of the crisis due to COVID19. The ‘territorialized’ model of circular economy is the ‘circular city’ model.
Cities are in search of nature-based solutions: which ones?
A multidimensional approach is proposed for interpreting the integration of humanistic paradigm with the ecological paradigm (that allows considering also the needs of human beings of the future generations) and to support the planning processes for development from the perspective of the circular economy and circular city model. The originality of this proposal consists, on the one hand, in assuming objectives/criteria emerging from the strategies of the Agenda 2030, New Urban Agenda, European Green Deal and, on the other hand, in focusing on the integration of the proposal of the World Health Organization about the integration of the environmental, economic and social impacts produced by climate change. Planning, designing and managing choices should identify preferable nature-based solutions in which nature becomes the most important city infrastructure.
Which new relationships between metropolitan areas and towns? Which actions for moving towards a more desirable city? For improving also the cultural city resilience? Which new researches in Universities for improving the comprehensive city resilience and the best defence against this and future crises?
