Urban surface temperature behaviour and heat island effect in a tropical planned city

 Putrajaya is a model city planned with concepts of a "city in the garden" and an "intelligent city" in the tropics. This study presents the behaviour of the surface temperature and the heat island effect of Putrajaya. Findings show that heat island intensity is 2 °C on average at nighttime and negligible at daytime. But high surface temperature values were recorded at the main boulevard due to direct solar radiation incident, street orientation in the direction of northeast and southwest and low building height-to-street width ratio. Buildings facing each other had cooling effect on surfaces during the morning and evening hours; conversely, they had a warming effect at noon. Clustered trees along the street are effective in reducing the surface temperature compared to scattered and isolated trees. Surface temperature of built up areas was highest at noon, while walls and sidewalks facing northwest were hottest later in the day. Walls and sidewalks that face northwest were warmer than those that face southeast. The surface temperatures of the horizontal street surfaces and of vertical façades are at acceptable levels relative to the surface temperature of similar surfaces in mature cities in subtropical, temperate and Mediterranean climates. © 2014 Springer-Verlag Wien.

Long-term water supply planning in an Australian coastal city : Dams or desalination?

Water resource managers and planners are continually involved in defining and evaluating alternative policies to better meet changing water supply conditions and the expectations of society. To undertake such long-term water supply planning, this study developed a novel integrated system dynamics model to combine economic, social and scientific variables and considerations within the planning horizon. Extensive sensitivity analysis for these variables was considered in this long term water resource planning process. The analysis suggests that over a longer time horizon, desalination provides a more viable, cost effective and secure bulk water supply alternative when compared to building large rain-dependent dams.

Urban heat island and wind flow characteristics of a tropical city

 Urban Heat Island (UHI) has become a growing concern to the quality of densely built urban environments, particularly in tropical cities. Wind speed has widely been reported to have decreased the intensity of heat island effect in urban areas. The cooling effect of the wind helps to mitigate the adverse effects of heat island on the micro climate and human thermal comfort. This paper investigates the existence of heat island in Muar, one of the fast growing cities in southern part of Malaysia and its possible causes, and then examines the effects of different urban geometry on the wind flow. The results of this study indicate that the chaotic development in Muar has caused reduced ventilation in urban canyons. The heat island intensity in the city center was recorded as 4. °C during the day and 3.2. °C during the night. Investigation of various urban geometry modifications showed that step up configuration was the most effective geometry as it can distribute the wind evenly allowing the wind to reach even the leeward side of each building. © 2014 Elsevier Ltd.

Religion, heritage and the sustainable city : Hinduism and urbanisation in Jaipur

The speed and scale of urbanisation in India is unprecedented almost anywhere in the world and has tremendous global implications. The religious influence on the urban experience has resonances for all aspects of urban sustainability in India and yet it remains a blind spot while articulating sustainable urban policy.This book explores the historical and on-going influence of religion on urban planning, design, space utilisation, urban identities and communities. It argues that the conceptual and empirical approaches to planning sustainable cities in India need to be developed out of analytical concepts that define local sense of place and identity. Examining how Hindu religious heritage, beliefs and religiously influenced planning practices have impacted on sustainable urbanisation development in Jaipur and Indian cities in general, the book identifies the challenges and opportunities that ritualistic and belief resources pose for sustainability. It focuses on three key aspects: spatial segregation and ghettoisation; gender-inclusive urban development; and the nexus between religion, nature and urban development. This cutting-edge book is one of the first case studies linking Hindu religion, heritage, urban development, women and the environment in a way that responds to the realities of Indian cities. It opens up discussion on the nexus of religion and development, drawing out insightful policy implications for the sustainable urban planning of many cities in India and elsewhere in South Asia and the developing world.

The Australian middle class and education: a small-scale study of the school choice experience as framed by ‘My School’ within inner city families

With the launch of the ‘My School’ website in 2010, Australia became a relative latecomer to the publication of national school performance comparisons. This paper primarily seeks to explore the school choice experience as framed by ‘My School’ website, for participating middle-class families. We will draw on Bourdieusian theory of cultural capital and relationship networks and Australian-based school choice research in order to contribute to understandings regarding the application of ‘My School’ data within participating families. Data collection consisted of qualitative, semi-structured, in-depth interviews with five families, each based within inner-city suburbs of Melbourne, Victoria. The findings of this small-scale study indicate that participating middle-class families possessed highly developed strategies for locating and achieving enrolment in school-of-choice and therefore did not seek to apply available data on ‘My School’ to decision-making, despite each participant reviewing the available data.

Popular imperialism, Scottish identity, and William Wallace in an Australian colonial city

The narrative of William Wallace holds a prominent position in the current conception of England as a negative referent for Scotland’s national identity—its binary “Other”, against which Wallace valiantly fought. This article considers a contrasting understanding of Scottish national identity from the late-nineteenth century, and explores the events surrounding the unveiling of a statue of William Wallace in Australia during the year of 1889. It illuminates how settlers interpreted this national hero in such a way that demonstrated loyalty to the Union and Empire, and accommodated a convergence of English, Scottish, Irish, and Welsh migrants in a British colonial city. The article highlights how statues, the ceremonies surrounding them, and their public reception help us to investigate the symbolic, ritualistic, and performative dimensions of identity formulation. It considers how public monuments, providing a sense of authority to particular groups, can marginalise others by acting to settle cultural competition, and will reflect on competing interpretations of the statue at its unveiling.

Alcohol-related crime in city entertainment precincts: Public perception and experience of alcohol-related crime and support for strategies to reduce such crime

INTRODUCTION AND AIMS: Bars, pubs and taverns in cities are often concentrated in entertainment precincts that are associated with higher rates of alcohol-related crime. This study assessed public perception and experiences of such crime in two city entertainment precincts, and support for alcohol-related crime reduction strategies. DESIGN AND METHODS: A cross-sectional household telephone survey in two Australian regions assessed: perception and experiences of crime; support for crime reduction strategies; and differences in such perceptions and support. RESULTS: Six hundred ninety-four people completed the survey (32%). Most agreed that alcohol was a problem in their entertainment precinct (90%) with violence the most common alcohol-related problem reported (97%). Almost all crime reduction strategies were supported by more than 50% of participants, including visitors to the entertainment precincts, with the latter being slightly less likely to support earlier closing and restrictions on premises density. Participants in one region were more likely to support earlier closing and lock-out times. Those at-risk of acute alcohol harm were less likely to support more restrictive policies. DISCUSSION AND CONCLUSIONS: High levels of community concern and support for alcohol harm-reduction strategies, including restrictive strategies, provide policy makers with a basis for implementing evidence-based strategies to reduce such harms in city entertainment precincts.
