Ideas, implementation and indicators: epistemologies of the post-2015 urban agenda

The success of the campaign for a dedicated urban Sustainable Development Goal (SDG) reflected a consensus on the importance of ?cities? in sustainable development. The relevance accorded to cities in the SDGs is twofold, reflected both in the specific place-based content of the Urban Goal and the more general concern with the multiple scales at which the SDGs will be monitored will be institutionalized. Divergent views of the city and urban processes, suppressed within the Urban Goal, are, however, likely to become more explicit as attention shifts to implementation. Acknowledging the different theoretical traditions used to legitimize the new urban agenda is an overdue task. As this agenda develops post-2015, the adequacy of these forms of urban theory will become more contested around, among other concerns, the possibilities and limits of place-based policy, advocacy and activism; and ways of monitoring and evaluating processes of urban transformation along multiple axes of development.
