A commentary on the New Urban Agenda.

The New Urban Agenda (NUA) was adopted at Habitat III, the United Nations Conference on Housing and Sustainable Urban Development, which was held in Quito, Ecuador, in October 2016. This paper is informed in large measure by the resulting documentation on the so-called 'Quito Declaration' and accompanying 'Implementation Plan' set out in the official NUA publications prepared by UN Habitat, as well as drawing on various supporting documents prepared by other UN agencies in the wake of the Declaration. The Implementation Plan lists 175 commitments and principles that respond to the vision and ambitions in the Declaration in which the building of more resilient urban settlements and supporting infrastructure is implicitly seen as the pathway to sustainability, and the adoption of more climate-friendly urban planning and development protocols is therefore a priority. While such ambition is clearly laudable, the paper questions the efficacy of the Agenda's key principles and associated development guidelines, and asks if these are sufficiently detailed to inform policy makers in pursuit of its aspirations, as well as questioning their flexibility as implementation tools to accommodate geographically specific contextual differences in disparate urban settings. It is not therefore a research paper in the normally accepted academic sense, but is simply an essay-cum-commentary on the Agenda's progress as it seeks to promote good practice in urban planning, and whether this is likely to deliver on more sustainable development that is also responsive to climate change imperatives.
