This article explores how the volumetric characteristics of cloud computing can create new expressions of territoriality, which in turn can reveal new axes of vulnerability and threat. Whilst recent work in political geography has sought to “locate” the cloud through analyses of data centre geographies and data-driven processes of smart urbanism, we look beyond the material plane and consider the amorphous territorialities of voluminous data instead. As much as these data are acted on by the legal-regulatory mechanics of the state in a bid to territorialise them, so too do these data volumes serve to cloud, and thus obscure, territory. Processes of territorialising and clouding exist in a state of dialectical tension with each other, and reveal the volumetric vulnerabilities of cloud computing. We validate these theoretical claims through an analysis of in-depth interviews with senior stakeholders in Singapore's Smart Nation initiative. In Singapore, defending the city is equivalent to defending the nation, which causes the military to play an outsized role in securing the city-state. We consider how the attack surface of the city becomes a more voluminous construct with cloud computing, how strategies of geofencing attempt to secure the cloud, and how these processes reveal the increasingly militarised conjunctures of everyday life. Overall, these insights reveal a need for political geography to continually evolve its theoretical premises in line with the rapid digitalisation of the world.

This paper advances the idea of ‘educational infrastructures’ to explore the slippages created by national education frameworks and the everyday ways in which citizen-subjects learn to be part of an ethno-cultural community. In doing so, we tease apart the differences between education as a top-down process of citizen-making and learning as a poly-directional assemblage of behaviours and influences that permeate the socio-spatial landscapes of ethnic belonging. We illustrate these theoretical arguments through an analysis of Singapore’s diasporic Indian community and the collapse of linguistically and culturally complex community backgrounds under the Mother Tongue policy. This leads to a pluralisation of learning and negotiation of identity for young people as they attempt to forge their own identities amidst a homogenising sense of ‘Indianness.’ By tracing the evolution of Singapore’s language policies, this paper demonstrates how educational infrastructures come to fill the gaps created by a state-wide commitment to multiculturalism.

A burgeoning literature on ‘left behind’ places has emerged that captures the backlash against globalisation and highlights the locales that lag world cities. This paper integrates the ‘left behind’ and world cities literatures through the lens of discontent in the context of Singapore, using sentiment analysis and topic modelling as well as interviews with local professionals to unpack the multidimensional aspects of discontent. Focusing on the Singapore–India Comprehensive Economic Cooperation Agreement that spurred discontent directed at foreign Indian professionals, we show that the worlding generated by transnational flows has accentuated intra-urban inequality through racialisation and spatialisation of financial business and suburban residential hubs. Discontent from intra-urban inequality unsettles years of efforts by the state to cultivate cosmopolitan spaces aimed at reducing social exclusion and difference in the world city of Singapore.

In the literature on policy design, the topic of citizen or policy-taker compliance, or the lack thereof, has been understood mainly in terms of economistic motivations responding to incentives and deterrents. That is, until recently. A pronounced turn toward behavioral public policy over the last two decades has diversified the set of possible propositions that are available for policy design scholars to study policy-takers. Consequently, how the diversity of policy-taker motivations and behavioral responses can be considered in the design of policy mixes and their implementation is an emerging area of study. Here, we contribute to this research effort by conceptualizing how the motivations of policy-takers affect their compliance response to the calibration of different types of policy instruments. We first elaborate on the inter-relationships between heterogenous policy-taker motivations, policy instrument calibrations, and heterogenous behavioral responses. Next, we use the example of Singapore’s approach to the management of a cyclical environmental disease (dengue) to illustrate the mix of motivations on the part of policy-takers. We then offer some thoughts on how policy instrument calibrations can be deployed to target heterogenous policy-taker motivations and induce greater policy participation.

We structurally estimate the firm-level frictions across prefectures in China and quantify their aggregate and distributional implications. Based on a general equilibrium model with input and output distortions and migration, we show that the firm-level frictions are less dispersed and less correlated with firm productivity in richer prefectures. Counterfactual exercises show that reducing the within-prefecture misallocation increases aggregate welfare, discourages migration toward large prefectures, and reduces spatial inequality. Moreover, internal migration alleviates micro-frictions’ impacts on aggregate welfare and worsens their effects on spatial inequality.

As global warming and urbanisation intensify unabated, a growing share of the human population is exposed to dangerous heat levels. Trees and forests can effectively mitigate such heat alongside numerous health co-benefits like improved mental wellbeing. Yet, which forest types are objectively and subjectively coolest to humans, and how thermal and mental wellbeing interact, remain understudied. We surveyed 223 participants in peri-urban forests with varying biodiversity levels in Austria, Belgium and Germany. Using microclimate sensors, questionnaires and saliva cortisol measures, we monitored intra-individual changes in thermal and mental states from non-forest baseline to forest conditions. Forests reduced daytime modified Physiologically Equivalent Temperature (mPET; an indicator for perceived temperature) by an average of 9.2 °C. High diversity forests were the coolest, likely due to their higher stand density. Forests also lowered thermal sensation votes, with only 1 % of participants feeling ‘warm’ or ‘hot’ compared to 34 % under baseline conditions. Despite the desire for a temperature increase among 47 % participants under cool forest conditions, approximately two-thirds still reported feeling very comfortable, in contrast to only one-third under baseline conditions. Even at a constant perceived temperature, participants were 2.7 times more likely to feel warmer under baseline conditions compared to forests. A forest-induced psychological effect may underlie these discrepancies, as supported by significant improvements in positive and negative affect (emotional state), state anxiety and perceived stress observed in forests. Additionally, thermal and mental wellbeing were significantly correlated, indicating that forest environments might foster a synergy in wellbeing benefits.

This paper foregrounds the importance of underlying territorial formations in realising a vision of the smart city. It argues that as a political technology of the state, territory should be understood as a platform upon which data works and the smart city unfolds. In this view, island territories – of which bordered city-states like Singapore provide paradigmatic examples – provide an integral, yet hitherto unexplored, component in the realisation of urban ‘smartness’. We illustrate these theoretical arguments through an analysis of how the territorial constraints that characterise Singapore’s island platform enable the state to accurately and effectively realise its vision of a smart city. As both an island city and a city-state, Singapore’s territory is a political technology that is just as important in realising the state’s vision of smartness as the adoption of digital technologies and the management of data. Drawing on 27 interviews with 31 architects of Singapore’s Smart Nation, we empirically explore the integration of data, city and territory through the platform; the ‘hardness’ of data and the ‘softness’ of the city; and the hyper-terrestrialisation of ‘smartness’ in Singapore. Overall, we demonstrate how the idea of territory as a platform provides a generative counterpoint to critiques of platform urbanism.

Future urban planning requires context-specific integration of spatial design and microclimate especially for tropical cities with extreme weather conditions. Thus, we propose a Combined Spatial-Climatic Design approach to assess impact of urban densification on annual outdoor thermal comfort performance employing ENVI-met simulations for Singapore. We first consider building bylaws and residential site guidelines to develop eight urban-density site options for a target population range. We further classify annual weather data into seven weather-types and use them as boundary conditions for the simulations. Comparing such fifty-six combined spatial-climatic simulation outputs by analyzing Outdoor Thermal Comfort Autonomy, we report the influence of site geometry is nominal on air temperatures but significant for mean radiant temperatures and physiological equivalent temperatures. Neighborhoods with taller (20% increase in mean height) buildings and narrower footprints exhibit better thermal performance compared to short and wider (12-58% decrease in mean width) buildings, due to less radiative heat gain during solar noon. For a high density tropical urban context, like Singapore with high sun angle and solar radiation, mutual shading and presence of wind enhances thermal comfort. Results provide useful and actionable recommendations on ideal building profile for heat responsive neighborhoods in low-latitude hot-humid cities similar to Singapore.

More frequent heat extremes, combined with rapidly developing settlements in the tropics, result in complex climate-driven risks emerging in cities within these regions. Urban policymakers can successfully manage these urban heat risks via climate resilient development, in which sustainability is aligned with current climate adaptation and mitigation goals.
