Cities round the world are reimaging the future, using the pandemic as an opportunity to come up with urban solutions that will make live better and more prepared for crisis. They are aspiring to create greener spaces in their urban areas, improve connectivity, reduce congestion, focus on sustainability, be more adaptive and smarter with technology and materials. As people have been forced inside, out of schools and workplaces as well as away from one another, new challenges have been presented. Life may not return to the way it once was. Cities will need to adapt to a new reality and there are no universal solutions. The hosting of the fourth edition of Cities 4.0 will once again provide the governments, municipalities, urban planners, developers, urban futurists, solution providers and innovators an interactive platform converge and discuss on methods and best practices to re-imagine our fundamental relationship with the cities, the opportunities to work outside their normal methods.
