Dr. Serafini argues that today we live in a very dynamic world. Over the next thirty years in the 600 largest cities in the world there will be a population growth of 40 % and an increase of world GDP by 42 %.
In this context, the future role of cities can only be to the megalopolis.
The only italian city that can aim to become a megalopolis is Milan, because it has a hinterland expanding and has a keen sense of urbanization.
Serafini also talked about the expo theme, a successful event thanks to the theme , the food . which is part of the four Italian F: Food, Fashion, Football and Ferrari, that representing the made in Italy in the world.
