Drawing on a growing literature on vertical and volumetric urbanism and a recent ¿subterranean turn¿ in geography, this paper explores the materiality and material agency of the underground and its entwinement with aboveground planning and development. The paper focuses on urban regeneration and planning in Newcastle, Australia: a city where underground coal mining has been deeply entwined in the establishment, economic prosperity, and geographical spread of the city, leaving the city undermined by multiple mine shafts (voids). Our analysis reveals the interconnectedness of vertical and horizontal capacities of the city and how this has shaped recent urban regeneration initiatives. Positioning the underground as a vital and agentic element of the wider urban assemblage and constitutive of the aboveground, we explore how its material presence (or, in this case, absence) is made visible through mapping techniques, and how its agency shapes the form, function and politics of urban development. Our analysis empirically traces the material agency of the underground at two scales. First, we examine how underground voids affect construction and financial viability at the building level. Second, we unpack how the presence of underground voids across the inner-city shapes precinct and city-scale regeneration initiatives, influencing the form and function of the city. The paper builds our understandings of volumetric urbanism and the subterranean, teasing out empirically the intertwinement of the aboveground and underground, and surfacing the material agency of the underground and its influence on the pathways and politics of aboveground urban development.

The demands passengers place on contemporary public transport systems are increasingly focused on providing a safe, comfortable and reliable transport experience. One expression of these demands is the recent introduction of designated quiet carriages to trains. The experience of travelling in these spaces has been given little academic scrutiny. Using a case study of the commuting experience between Newcastle and Sydney, New South Wales (NSW), Australia, this paper investigates the practices, relations and affective atmospheres of quiet carriages. The paper argues that passengers on trains come together to craft quiet through interactions between human and material actors. This crafting of quiet results in noticeably different quiet atmospheres at different times of day and in different parts of the journey. Drawing on participant observation including an auto-ethnographic account of travelling in a quiet carriage, the paper distinguishes between four types of quiet crafted by the passenger collective¿sleepy and comfortable quiet, busy quiet, tense quiet and spooky quiet. These four types of quiet play upon the body with different intensities and some have stronger affects that linger after the completion of the journey.

In critical urban studies, managed urban regeneration has been linked to trajectories of neo-liberalising urban policy and urban entrepreneurialism. While the insights arising from this work have been many and valuable, significant gaps remain particularly in terms of the foci of analysis and the conception of politics. In this paper, we aim to address these gaps and to reposition the conceptualization of regeneration as a performed and emergent consequence of ¿relatedness¿ and as subject to a range of relational effects and determinations. To do so we work through four capacities of assemblage thinking that are particularly productive for this task: (i) revealing the relational, multiple and processual nature of urban trajectories; (ii) revealing the multi-scalar labouring involved in configuring the (socio-material) assemblages that constitute regeneration; (iii) identifying openings for multiple possible trajectories of regeneration; (iv) providing critical insights into how regeneration trajectories are constrained. We conclude with reflections on what assemblage thinking offers in terms of critically and generatively rethinking urban regeneration.

Data sharing adds considerable value to interagency programs that seek to tackle complex social problems. Yet data sharing is not easily enacted either technically or as a governance practice, especially considering the multiple forms of risk involved. This article presents insights from a successful data sharing project in a major region in east coast Australia involving a federally funded research partnership between two universities and a number of human services agencies. The Spatial Data Analysis Project sought to establish a community of practice for devising data sharing protocols and embedding data sharing into agency practices. Close dialogue between the project partners and mobilizing the authority of extant regulatory and legal frameworks proved effective in confronting risks and barriers. The article reveals effective practices for data sharing and derives lessons for other policy and governance contexts.

The shift towards social, government and corporate ethics which value environmental sustainability has also embraced householders in a plethora of educational guides, policies, regulations and consumer information about green home improvements, purchasing choices and household practices. In this paper, we make the claim that the rental housing sector, and in particular the private rental sector, has yet to participate, structurally, culturally and materially, in this shift to an ethics of sustainability. We argue, however, that even on such otherwise arid ground, an alternative ethic is developing, a sustainability ethic practiced by green tenants whose activities inside and outside their homes go beyond the considerable material constraints of their dwellings and incomes, and beyond the purely transactional utility of the rental contract. These activities, relational, interconnected and resilient, offer both glimpses of a greening rental housing sector, and a clearer picture of the areas where work remains to be done. Based on a research study, we conducted of the rental sector in regional Australia, and in particular of the everyday sustainability practices of tenants, we suggest that these activities are a practice-based form of care for the world, in many ways similar to Maria Puig de la Bellacasa's practice-based, human-decentred ethics which she suggests is exemplified in the permaculture movement. The stories of the tenants we interviewed for our study also point the way to other changes which are needed to enable a practice-based sustainability ethic to flourish across the rental housing sector as a whole.

Over the past several decades, risk has become a distinct field of social inquiry as scholars in a variety of disciplines have developed theories about the 'nature' of risk and the role it plays in contemporary society. Collectively, these theories enrich our understanding of the politics of risk, the dynamics of risk perception, and the way risk shapes and is shaped by space, culture, social change, and modes of governing in the neoliberal era. In this paper, however, we argue these theories are helpful but not entirely suited to understanding risk when it becomes the subject of something Whatmore (2009, p. 587, 2013) calls "environmental knowledge controversies". These controversies are generative events where more-than-human agencies and the political and knowledge making practices of heterogeneous actors reshape our sense of the real. To address this issue, we draw on the concepts of enactment, multiplicity, and ontological politics to explore how different kinds of risk and tree were made more or less real during a contentious debate over the risk posed by a group of urban trees in Newcastle, Australia. This case study suggests we can think of risk and hazardous entities like trees as effects that also affect because they elicit interventions that transform bodies and spaces in more or less enduring ways. Attending to the enactment, multiplicity, and ontological politics of risk, we argue, provides an alternative way to navigate moments of political contestation over the assessment and management of risk that has implications for how these processes are conceived and conducted in the future. © 2014 Elsevier Ltd.
