Goal 11 of the Sustainable Development Goals (SDGs) sets out to make cities inclusive, safe, resilient and sustainable by 2030. Together with the New Urban Agenda adopted at the Habitat III conference in Quito in 2016, SDG 11 is the latest emanation of the thickening layer of international normative guidance on questions of sustainable development and urban governance. This chapter argues that Goal 11 of the SDGs is a clear expression of the urban turn, as it were, in global governance. The contribution contextualizes the setting in which SDG 11 is inserted as well as the aspirations of Goal 11. The chapter also unearths the inherent contradictions of SDG 11 since not all of its sub-goals will be attainable at the same time and without negatively impacting on some of the other SDGs. For instance, the notions of ‘safety’ and ‘inclusiveness’ might well conflict with each other. The chapter concludes with a critical view on some of the general implementation risks and challenges associated with SDG 11.
