Postcards from sustainable cities of the future

While we are experiencing the Covid-19 pandemic in the world, we ask ourselves about many aspects of our lives and above all we ask ourselves if some behaviors and habits will remain the same as in the past or will undergo transformations. In this panorama we try to imagine future scenarios for our cities, for a different use of public spaces, more inclusive, which responds to the needs and desires of different urban populations: children, elderly, animals, non-human agents, etc. We present the first experiments, carried out in an academic sphere, but easy to replicate and generate new social challenges. It is just a starting point for possible future scenarios, in terms of the spaces we live and everyday use, relationships with others, intercultural connections, and how to give importance to the factor of time. Surprisingly, changing from a fragile present to a mutable future thanks to creating new inclu- sive and innovative possible systems, with imagination and follow with project proposals. The ability to resist and be resilient to the transformations, are giving a new meaning to ideas, concepts, or expectations that we thought were clear. In this never-before-seen pandemic scenario, we are all called upon to act, especially those involved in Design, with the intention of envisioning potential solutions from the short-term to a long-term legacy.
