How can we achieve social integration in cities?
In the recently posted talk by Eduardo Paes, which seems to be controversial in how it represents the quality of life in Rio DeJaneiro, the mayor of that city identifies as his third commandment that cities be socially integrated.
What does social integration mean to you in terms of how the residents of cities should be connected to each other and what are the best means we have of achieving such integration?
Examples of practical strategies that have worked in real cities would be very instructive. As the comments on the talk already provide a forum for discussing the accuracy of the mayor's depiction of his city, it would be wonderful if the discussion here could focus rather on the specific issue of promising strategies for social integration.
