While there is a relatively extensive literature concerning the nature of smart cities in general, the roles of corporate actors in their production and the development and deployment of specific smart city technologies, to date there have been relatively few studies that have examined the situated practices by which the smart city unfolds in specific places. In this paper, we draw on three sets of interviews ( n = 114) and ethnographic fieldwork to chart the smart city ecosystem in Dublin, Ireland. We examine how the four city authorities have actively collaborated to frame a disparate and uncoordinated set of information and communication technology-led initiatives, what Dourish terms the ‘accidental smart city’, into an articulated vision of Dublin as a smart city. In particular, we focus on the work of ‘Smart Dublin’, a shared unit established to coordinate, manage and promote Dublin’s smart city initiatives and to drive new economic development opportunities centred on corporate interventions into urban management and living. Our analysis highlights the value of undertaking a holistic mapping of a smart city in formation, and the role of political and administrative geographies and specialist smart city units in shaping that formation.

We argue that the ideas, ideals and the rapid proliferation of smart city rhetoric and initiatives globally have been facilitated and promoted by three inter-related communities: (i) `urban technocrats'; (ii) a smart cities `epistemic community'; (iii) a wider `advocacy coalition'. We examine their roles and the multiscale formation, and why despite their influence they encounter a `last mile problem'; that is, smart city initiatives are yet to become fully mainstreamed. We illustrate this last mile problem through a discussion of plans to introduce smart lighting in Dublin.

In this paper, we argue that the ideas, ideals and the rapid proliferation of smart city rhetoric and initiatives globally have been facilitated and promoted by three inter-related communities. A new set of 'urban technocrats' -chief innovation/technology/data officers, project managers, consultants, designers, engineers, change-management civil servants, and academics -many of which have become embedded in city administrations. A smart cities 'epistemic community'; that is, a network of knowledge and policy experts that share a worldview and a common set of normative beliefs, values and practices with respect to addressing urban issues, and work to help decision-makers identify and deploy technological solutions to solve city problems. A wider 'advocacy coalition' of smart city stakeholders and vested interests who collaborate to promote the uptake and embedding of a smart city approach to urban management and governance. We examine the roles of new urban technocrats and the multiscale formation and operation of a smart cities epistemic community and advocacy coalitions, detailing a number of institutional networks at global, supra-national, national, and local scales. In the final section, we consider the translation of the ideas and practices of the smart city into the policies and work of city administrations. In particular, we consider what might be termed the 'last mile problem' and the reasons why, despite a vast and active set of technocrats and epistemic community and advocacy coalition, smart city initiatives are yet to become fully mainstreamed and the smart city mission successfully realized in cities across the globe. We illustrate this last mile problem through a discussion of plans to introduce smart lighting in Dublin.

When attendant to the agency of models and the general context in which they perform, climate models can be seen as instrumental policy tools that may be evaluated in terms of their adequacy for purpose. In contrast, when analysed independently of their real-world usage for informing decision-making, the tendency can be to prioritise their representative role rather than their instrumental role. This paper takes as a case study the development of the UK Climate Projections 2009 in relation to its probabilistic treatment of uncertainties and the implications of this approach for adaptation decision-making. It is considered that the move towards ensemble-based probabilistic climate projections has the benefit of encouraging organisations to reshape their adaptation strategies and decisions towards a risk-based approach, where they are confronted definitively with climate modelling uncertainties and drawn towards a more nuanced understanding of how climate impacts could affect their operations. This is further illustrated through the example of the built environment sector, where it can be seen that the probabilistic approach may be of limited salience for the urban heat island in the absence of a corresponding effort towards a more place-based analysis of climate vulnerabilities. Therefore, further assessment of the adequacy-for-purpose of climate models might also consider the usability of climate projections at the urban scale.
