Dharavi might hold little charm for a Mumbaikar, but for Antoni Vives, former deputy mayor of Barcelona (2011-2015), it is a lesson in what was once right but now wrong with Mumbai. During a visit to the city a few months ago, Vives, a consultant with the Pune Smart City Development Corporation Limited (PSCDCL), decided to spend an entire day in the slum, out of sheer curiosity. "What I discovered was how this close-knit space generated social bonds between its residents.

But with very good intentions, somebody has decided to tear it all down and put the people into high-rises. In the process, they are breaking the only thing that these communities have - their social bonds," he says.
