The acceleration of transitions to urban sustainability: a case study of Brighton and Hove

Cities raise major challenges and opportunities for achieving sustainability. Much literature on urban sustainability focuses on specific aspects such as planning practices, urban policy or the diffusion of more sustainable technologies or practices. However, attempts at understanding the mechanisms of structural change towards sustainability have resulted in the emergence of an interdisciplinary field of sustainability transitions research. Transitions research has developed a phase model of transitions in which predevelopment, take-off, acceleration and stabilization phases are distinguished. However, the acceleration phase has received limited attention so far. This is a crucial gap as policy-makers are keen to accelerate transitions. This paper aims to enhance our understanding of how local actions contribute towards accelerating urban sustainability transitions. It does so by testing an acceleration mechanisms framework through exploring the collective agency of local initiatives in urban sustainability transitions. Drawing on a case study of the city of Brighton and Hove (UK), the paper finds that despite favourable local political conditions, there is a lack of evidence of acceleration apart from in individual domains such as food or mobility. Progress is found to depend on the agency of initiatives to both scale up sustainable practices and embed these practices into local governance arrangements.     

The Impact of Local Environmental Advocacy Groups on City Sustainability Policies and Programs

American cities vary considerably in the degree to which they pursue sustainability. What explains this variation? One plausible cause of such differences is that sustainability may be more appealing to high‐income cities than to more economically challenged cities. Yet such strict economic determinism seems simplistic and removes politics from an inherently political process. The hypothesis here is that any such relationship between income and commitment to sustainability is conditioned by a city's level of environmental advocacy. The data utilized in this analysis are derived from two large‐scale data sources. One is a comprehensive inventory of sustainability programs and policies in 50 large American cities. The other is a set of surveys in those same 50 cities. The multivariate model supports the hypothesis. Controlling for income growth and the predisposition of policymakers to be supportive of sustainability (as well as other alternative explanations), a city's commitment to sustainability is strongly linked to the advocacy of environmental and sustainability groups in the policymaking process. The example of Sustainable Seattle is used to illustrate the linkages that would seem to underlie the statistical analysis.     

Urban smartness and sustainability in Europe. An ex ante assessment of environmental,social and cultural domains

The aim of the paper is to define a set of smartness and sustainability indicators applicable to European cities and to assess their outcome in an ex ante perspective with regard to the implementation of Europe 2020 strategy. Following the DPSIR (Driving forces, Pressures, State, Impact, Response) model, we select a bundle of indicators for three relevant sustainability domains (environmental, social and cultural), which are proper to the smart city definition. Then we define groups of homogeneous cities for each domain by using a two-step cluster analysis. Results show the existence of heterogeneous groups of cities that are likely to become smart in the cultural domain, side by side with groups of more developed urban areas that have acquired a substantial advantage in the environmental and social dimensions.

Renewable energy innovations and sustainability transition: How relevant are spatial spillovers?

In the societal challenge to switch to renewable energy, innovation has become an ever‐increasing critical determinant. However, while sustainability transition is a global challenge, diffusion and adoption of innovation tends to be uneven in space and unequal access may cause substantial heterogeneity in energy transition. This research analyzes how domestic and foreign innovation activities in the renewable energy sector influence energy transition over time. Empirical testing shows that a country's domestic innovation activity impacts renewable electricity generation capacity sooner than foreign technological innovations. I document that there are substantial barriers to substitute foreign technologies for domestic innovation efforts in the short run but also observe that foreign technologies have a stronger impact after some years. These findings have implications for cross‐border coordination of governmental innovation support and complementary policy instruments that aim at increasing adoption speed across borders.     

Contrasts between first-tier and second-tier cities in Europe: a functional perspective

Second-tier cities have been experiencing renewed interest within policy and research contexts, which is reversing a tradition of relative neglect due to the long-standing focus on large cities and capitals. This paper compares European second-tier and first-tier cities with regard to the presence of urban functions and how these are spread over their urban regions. The analysis shows the existence of a substantial ‘first city bonus’: a surplus of urban functions in first-tier cities which cannot be explained by their size or network embeddedness. We also show that second-tier cities are better served with urban functions in the absence of a dominant capital. In first-tier urban regions, the core municipality exploits the critical mass of the urban region to support its own functions, leaving that region functionally underserved. Second-tier cities lack this absorptive capacity, and their urban regions are endowed with more urban functions. These functional differences mean that second-tier cities demand a differentiated research and policy approach, in which city-regional integration becomes an important territorial development strategy. Rather than the dispersion process in first-tier cities leading to a ‘regionalization of the city’, integration in second-tier urban regions may be seen as a process of ‘citification of the region’.     

Energy efficiency left behind? Policy assemblages in Sweden’s most climate-smart city

ABSTRACT

Smart city experiments have the potential to reshape urban climate change governance. Smart city initiatives have been supported by international technology companies and the European Union for many years and continue to be promoted by national and municipal governments. In relation to sustainability and climate change, such initiatives promise more efficient use of resources through the use of information and communications technology in energy infrastructure. Experiments with smart city technologies such as urban smart grids have shown the potential to restructure relationships between energy utilities, energy users and other actors by reconfiguring the dynamics of energy supply and demand. But do urban experiments lead to institutional change? The aim of the article is to provide a better understanding of how smart city experiments reshape the urban governance of building energy use. Hyllie, a new city district in Malmö, Sweden, was home to two smart city experiments that contributed to the institutionalization of urban smart grid technology. However, the analysis of Hyllie’s policy assemblages shows that this institutional change could redefine sustainability at the expense of energy efficiency.

Mobilizing ‘juvenocratic spaces’ by the biopoliticization of children through sustainability

Northern children have been increasingly referred to as competent, participative and influential, called on to protect and produce certain life at times of climate risks. Child–adult relations and the required transition to adulthood are thus transformed by a re-configured ‘biopolitics’. We trace how various collaborative actors invite children to foster life at an aggregate level and illustrate how different age categories are governed at a distance. The results show that pedagogic expertise, in conjunction with sustainability, is mobilized in and by ‘juvenocratic spaces’, where youths are obliged to foster sustainable consumption and ways of living beyond territorial borders.     

Territorial development,planning reform and urban governance: the case of Ireland’s second-tier cities

The increased emphasis within Europe on the role of second-tier cities has implications for the ways in which these urban centres are considered within national spatial planning strategies. In centralized, monocentric states such as Ireland, there has been a general ambivalence towards urban policy for cities outside the capital city, and historically, this has prevented the development of a strong, diversified urban hierarchy undermining prospects for balanced regional development. This paper examines the extent to which a new found emphasis on Ireland’s second-tier cities which emerged in the ‘Gateways’ policy of the National Spatial Strategy was matched by subsequent political and administrative commitment to facilitate the development of these urban centres. Following a discussion of the position of second-tier cities in an international context and a brief overview of recent demographic and economic trends, the paper assesses the relative performance of Ireland’s second-tier cities in influencing development trends, highlighting a comprehensive failure to deliver compact urban growth. In this context, the paper then discusses the implications of current development plans for the second-tier cities and proposals for Irish local government reform for securing compact urban development.     

Who does the work in sustainable households? A time and gender analysis in New South Wales,Australia

Households in the affluent West have become an important target of government and NGO campaigns to encourage more environmentally sustainable behaviours, but there has been little research into the gender implications of such policies. This article investigates the role of gender and time in the sustainability practices of six heterosexual households with young children, committed participants in the Sustainable Illawarra Super Challenge programme in 2009. Women spent more total time on sustainable practices, and did so more often. Men's contributions related mostly to gardening and transport, in longer blocks of time. In these households, sustainability became a highly gendered practice because of the different roles in homemaking. Women resisted constructions of themselves as being closer to nature, and shouldered expectations of sustainability as part of their roles as mothers and household managers. They experienced time as overlapping and fragmented, with no distinction between work and leisure. Men contributed to sustainable practices mainly through activities understood as leisure, in longer blocks of time. Our temporality lens also illustrates the gendered ways that old practices become deroutinised and new practices reroutinised. While men were often responsible for the labour and upfront time required to start or research a project, the responsibility of everyday implementation and habit-changing commonly fell to women. These findings illustrate how gendered analyses help identify both opportunities for, and constraints against, change towards sustainability. Opportunities include the strong connections between both mothers' and fathers' understanding of good parenting and the importance they attach to household sustainability. Constraints include the temporal challenges faced by households, and how these interact with wider structural and labour roles.
