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.

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.

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.

This paper evaluates the distributional impacts of transportation networks in China.We show that the quality of roads and railroads vary substantially over time and space, and ignoring these variations biases the estimates of travel time. To account for quality differences, we construct a new panel dataset and approximate quality using the design speed of roads and railroads that varies by vintage, class, and terrain at the pixel level. We then build a dynamic spatial general equilibrium model that allows for multiple modes and routes of transportation and forward-looking migration decision.We find aggregate welfare gain and less spatial income inequality led by expanding transportation network.

Purpose: Although the Singapore model of ethnic integration through its public housing programme is well known, the formula for replicating its success elsewhere remains underexplored. This study aims to identify the criteria for successful transplantation, specifically by identifying the housing tenure types that are most amenable to the implementation of the Singapore model. Design/methodology/approach: Through a comparative study of two common law jurisdictions – Singapore and England – this article highlights the differences in their housing landscapes and how such differences impact upon the adoption of ethnic integration policies through housing. The article also unpacks, through a cross-disciplinary lens, the concepts of public housing and housing tenures, drawing heavily on socio-legal and housing literature. Findings: The authors observe that the implementation of ethnic integration policies is best justified and most easily achieved in leasehold estates that exhibit a strong tenurial relationship with the state retaining a more than notional role. Public housing in Singapore being an exemplar of this model, the implementation of its ethnic integration policy is relatively straightforward. By contrast, the shrinking public housing sector in England means that adoption of a similar policy would have limited reach. Even then, the political–legal environment in England that promotes home ownership is potentially hostile to the adoption of such policy as it may be seen as an infringement of private property right. Originality/value: The cross-jurisdiction comparison is supplemented by an interdisciplinary analysis that seeks to bridge differences in the categorisation of tenure in housing and law literatures so as to promote cross-disciplinary dialogue.

Strata titles are a critically important Australian legal export. New South Wales’ (NSW) strata legislation has been particularly influential, having been adopted in numerous jurisdictions, including Singapore in 1967. As a statutory framework, strata law solves the problem of ‘floating freeholds’ by creating indefeasible ownership of individual units in a building, guides owners in managing the development, and sets out the dispute resolution process when disagreements occur.

In an increasing number of jurisdictions (including Singapore and three states in Australia), strata legislation also enables the strata scheme to be terminated and sold for redevelopment where the requisite majority, as opposed to an unanimity of subsidiary proprietors’ consent to the sale. Strata law imposes compensation thresholds that must minimally be paid to dissenting owners. In Singapore, the rule is that no minority owner should suffer a ‘financial loss,’ while in NSW and Western Australia (WA), this amount is pegged to what the owner would theoretically have obtained had the unit been acquired compulsorily by the state. In this article, I compare strata law in Singapore, NSW, and WA in relation to compensation thresholds and explain why the Australian market value standard should also be adequate to compensate unit owners in Singapore.

Young women outnumber young men in cities in many countries during periods of economic growth and urbanization. This gender imbalance among young urbanites is more pronounced in larger cities. We use the gradual rollout of special economic zones across China as a quasi-experiment to establish the causes of this gender imbalance. Our analysis suggests that a key contributor is gender-differential incentives to migrate due to rural women’s higher likelihood of marrying and marrying up in cities when urbanization creates more economic opportunities and an abundance of high-income marriage-age men.

This article examines an alternative model of smart city formation, one based on the principle of insourcing technical competencies and capabilities to those responsible for city governance. This model counters the logic of technological outsourcing upon which many assumptions and critiques of the smart city rest, and thus reveals ways in which a more generative discourse can be forged. Drawing on a series of in-depth interviews with senior stakeholders from public and private sector organizations, we develop a case study of Singapore’s Smart Nation initiative. Through coordinated efforts to reorganize the public sector’s technological functions, develop nation-wide skills upgrading programs, and repatriate overseas tech talent, the government strives to assemble an ideo-technical ecosystem of talent, skills, and civic-mindedness in Singapore. This is an ecosystem designed to establish the public sector as the driver of urban innovation, and thus maximize the benefits of “civic tech”.

In all cities and urban areas, the risk faced by people and assets from hazards associated with climate change has increased (high confidence1 ). Urban areas are now home to 4.2 billion people, the majority of the world’s population. Urbanisation processes generate vulnerability and exposure which combine with climate change hazards to drive urban risk and impacts (high confidence). Globally, the most rapid growth in urban vulnerability and exposure has been in cities and settlements where adaptive capacity is limited, especially in unplanned and informal settlements in low- and middle-income nations and in smaller and medium-sized urban centres (high confidence). Between 2015 and 2020, urban populations globally grew by more than 397 million people, with more than 90% of this growth taking place in less developed regions.
