Regulative and supportive mechanisms at policy and planning level have been identified through
a comparative analysis of urban rejuvenation policies and actors' embeddedness. Those
mechanisms enable the development of contextualised parameters that support projection attempts
of future gentrification processes at the neighbourhood level. As a result a reflective
understanding of gentrification and policy recommendations are drawn at a general level. This
analysis argues that cities should include gentrification as a driving force in urban policies.
However processes of gentrification require mediation and monitoring by public authorities who
should be aware of the risk of social fragmentation.Diverging urban rejuvenation practices and
