How to reverse urban sprawl: The smart blue-green city

The phenomenon of urban sprawl is relatively widespread. At its root are a number of factors that have caused people to leave cities and settle relatively close to them. There are both positive and negative consequences of urban sprawl, but the latter are far more numerous, so solutions are needed. Therefore, four questions have been formulated for this paper: 1. What are the negative consequences of urban sprawl? 2. Are there positive aspects to the phenomenon? 3. Do the negative consequences outweigh the positive ones? 4. What should be done to mitigate the negative consequences of urban sprawl? This study aims to identify a set of actions that can reduce the identified negative consequences of urban sprawl. We believe that the key at the planning level is to implement the concept of the smart blue-green city, which respects social needs. The elements of the proposed solution have been selected with a view to reducing the phenomenon of urban sprawl, i.e. keeping people in the city, rather than designing the urban and suburban structure.
