Place-taking and place-making in waterfront renewal, Australia

Waterfront and port zones around the world have long been subject to change, as they have variously been used for trade, waste disposal, leisure and most recently for urban re-imagining, spectacle and lifestyle housing. While such a narrative has been well explored in the urban studies literature, another element of port development – its relation to imperialism and colonisation has not. In the case of colonized countries – such as Australia, but also Canada, the United States and across Africa and Asia – waterfronts were often the entry points of imperial occupancy and key sites for colonial trade and industry. Contestation over how to value and use these sites is integral to their constitution as landscapes, as place taking becomes part of their place making. It will be argued, using case studies drawn from Adelaide and Melbourne in Australia that these sites register a range of culturally-specific imprints connected to the colonisation process. For Indigenous Australians, sea country was indistinguishable from land, but subsequent assessments have seen land demarcated from the ocean, water defiled and obliterated, slums designated but then redeveloped and the Indigenous present rendered benign through its symbolic re-presentation. This post-colonial reading will correlate the divide between land and water with those who have the imperial and class power to define this elemental boundary to add a new dimension to studies of waterfronts.

Retake Melbourne : mobile application for re-photography and comparative imaging research

A project of interpretive and comparative re-photography, making use of the collection of Mark Strizic's images and the documents related to his career, held by the State Library, as a basis. Strizic died in 2012. It is now 50 years since his work began to illustrate the period of the 1960s when architecture of the Gold Rush era coexisted side-by-side with, and was being replaced by, curtain-glass high-rise office buildings. It is the position of the researchers that not sufficient attention has been given to Mark Strizic’s reaction to what he saw as a plague of ugliness pervading Australian city-scapes, developing a distinctive aesthetic that in turn made his work useful to commentators like Robin Boyd and David Saunders. Strizic operated from a unique perspective as a migrant with an architectural heritage from his father Zdenko, prominent architecture professor in Croatia, and visiting professor of architecture at Melbourne University in the 1960s. Precise re-photography alongside creative work will enable a comparison of Melbourne now with fifty years ago. The public will be able to participate in and contribute to the project via a crowd-funded custom-made app. Half a century has passed since Strizic made his photographs of Melbourne. In so many cases buildings have disappeared or altered, streetscapes have changed and the appearance of Melburnians have changed as have their habits of using the city. A selection of Strizic’s photographs of Melbourne locations can be rephotographed by the public using the methods devised by Mark Klett, assisted by the app software. This will provide a core of documentary imagery of benefit in framing and completing the rest of this project and to future research through comparisons over the time span. The app enables the location on a map of the site and orientation of photographs taken by Strizic. Photographs are downloaded onto users’ devices from the online SLV Strizic picture catalogue. They appear in the app as transparent templates so that users can line up their own re-photograph with accuracy. They will be able to upload their resultant images to a server and they will be available to the Library as an archive enabling direct comparison with the Strizic holdings. It is anticipated that involvement and participation of the public will elevate the profile of the project and publicise the SLV collections and encourage their increased usage and popularity.

Neoliberalism, economic restructuring and policy change : precarious housing and precarious employment in Australia

Housing, employment and economic conditions in many nations have changed greatly over the past decades. This paper explores the ways in which changing housing markets, economic conditions and government policies have affected vulnerable individuals and households, using Australia as a case study. The paper finds a substantial number and proportion of low income Australians have been affected by housing and employment that is insecure with profound implications for vulnerability. Importantly, the paper suggests that in Australia the economic gains achieved as a consequence of mining-related growth in the early 2000s were translated as greater employment security for some on low incomes, but not all. Enhanced access to employment in this period was differentiated by gender, with women largely missing out on the growth in jobs. For the population as a whole, employment gains were offset by increased housing insecurity as accommodation costs rose. The paper finds low income lone parents were especially vulnerable because they were unable to benefit from a buoyant labour market over the decade 2000–2010. They were also adversely affected by national policy changes intended to encourage engagement with paid work. The outcomes identified for Australia are likely to have been mirrored in other nations, especially those that have embraced, or been forced to adopt, more restrictive welfare and income support regimes.

Religion, urbanism and sustainable cities in South Asia

Religion and Urbanism contributes to an expanded understanding of 'sustainable cities' in South Asia by demonstrating the multiple, and often conflicting ways in which religion enables or challenges socially equitable and ecologically sustainable urbanisation in the region. In particular, this collection focuses on two aspects that must inform the sustainable cities discourse in South Asia: the intersections of religion and urban heritage, and religion and various aspects of informality.

This book makes a much-needed contribution to the nexus between religion and urban planning for researchers, postgraduate students and policy makers in Sustainable Development, Development Studies, Urban Studies, Religious Studies, Asian Studies, Heritage Studies and Urban and Religious Geography.

Optimal sensor placement and measurement of wind for water quality studies in urban reservoirs

We collaborate with environmental scientists to study the hydrodynamics and water quality in an urban district, where the surface wind distribution is an essential input but undergoes high spatial and temporal variations due to the complex urban landform created by surrounding buildings. In this work, we study an optimal sensor placement scheme to measure the wind distribution over a large urban reservoir with a limited number of wind sensors. Unlike existing sensor placement solutions that assume Gaussian process of target phenomena, this study measures the wind which inherently exhibits strong non-Gaussian yearly distribution. By leveraging the local monsoon characteristics of wind, we segment a year into different monsoon seasons which follow a unique distribution respectively. We also use computational fluid dynamics to learn the spatial correlation of wind in the presence of surrounding buildings. The output of sensor placement is a set of the most informative locations to deploy the wind sensors, based on the readings of which we can accurately predict the wind over the entire reservoir surface in real time. 10 wind sensors are finally deployed around or on the water surface of an urban reservoir. The in-field measurement results of more than 3 months suggest that the proposed sensor placement and spatial prediction approach provides accurate wind measurement which outperforms the state-of-the-art Gaussian model based or interpolation based approaches.

Demo abstract: wind measurements for water quality studies in urban reservoirs

Water quality monitoring and prediction are critical for ensuring the sustainability of water resources which are essential for social security, especially for countries with limited land like Singapore. For example, the Singapore government identified water as a new growth sector and committed in 2006 to invest S$ 330 million over the following five years for water research and development [1]. To investigate the water quality evolution numerically, some key water quality parameters at several discrete locations in the reservoir (e.g., dissolved oxygen, chlorophyll, and temperature) and some environmental parameters (e.g., the wind distribution above water surface, air temperature and precipitation) are used as inputs to a three-dimensional hydrodynamics-ecological model, Estuary Lake and Coastal Ocean Model - Computational Aquatic Ecosystem Dynamics Model (ELCOM-CAEDYM) [2]. Based on the calculation in the model, we can obtain the distribution of water quality in the whole reservoir. We can also study the effect of different environmental parameters on the water quality evolution, and finally predict the water quality of the reservoir with a time step of 30 seconds. In this demo, we introduce our data collection system which enables water quality studies with real-time sensor data.

Sensor placement and measurement of wind for water quality studies in urban reservoirs

We study the water quality in an urban district, where the surface wind distribution is an essential input but undergoes high spatial and temporal variations due to the impact of surrounding buildings. In this work, we develop an optimal sensor placement scheme to measure the wind distribution over a large urban reservoir using a limited number of wind sensors. Unlike existing solutions that assume Gaussian process of target phenomena, this study measures the wind that inherently exhibits strong non-Gaussian yearly distribution. By leveraging the local monsoon characteristics of wind, we segment a year into different monsoon seasons that follow a unique distribution respectively. We also use computational fluid dynamics to learn the spatial correlation of wind. The output of sensor placement is a set of the most informative locations to deploy the wind sensors, based on the readings of which we can accurately predict the wind over the entire reservoir in real time. Ten wind sensors are deployed. The in-field measurement results of more than 3 months suggest that the proposed sensor placement and spatial prediction scheme provides accurate wind measurement that outperforms the state-of-the-art Gaussian model based on interpolation-based approaches.

Developing family businesses through ongoing learning: case studies of Chinese urban and rural family businesses under market-oriented reforms

This study advances organisational learning research by exploring how and why learning patterns differ between different family businesses at different layers of China’s marketoriented transformation. The focus is the locational difference, namely the separate urban and rural environments and outcomes. Combining case studies and in-depth interviews, the study investigated how family businesses interact with their institutional environment and consequently build learning patterns. Learning initiatives undertaken by relevant and motivated family members are found to reflect a dynamic process involving personal learning, business growth, and business innovation. Family conflicts and business growth were also found to impact learning in family businesses. Implications for organisational learning are discussed at the end of the paper.

On the edge: how well do fire mitigation strategies work on the urban fringe?

The reduction of loss of lives and assets during bushfire is one of the primary aims or lire management agencies. Traditional fire mitigation strategies include strategic fire hreaks, static water points, management of ignition sources, rapid detection and local response, air attack, and fuel reduction burning. There have been few quantitative studies that assess the success or these strategies. We need to promote 'new' strategies more focused on human hehaviour and community preparedness.
DeJcndable space provides our best strategy for reducing losses during major bushfires. The size or the defendable space depends on the type of house to be defended, who is defending it, and the spatial context of the property. In the urban fi'inge, remnant vegetation on private property often has
high conservation values, and application of traditional mitigation strategies, as well as the vegetation modification required to achieve defendable space, may have significant impacts on conservation and biodiversity values.

Spatial analysis of urban stormwater quality

Urban stormwater non-point source pollutants are recognized as a major cause of receiving waters quality deterioration. To date most research has focused on specifying temporal variations of stormwater quality parameters which includes high uncertainties and also increases the risk of pollution control structures failure. Traditionally, the temporal variations of quality parameters in forms of either pollutograph or Event Mean Concentration (EMC) is obtained by sampling stormwater at the outlet of urban catchments for quality analysis in addition to measurement of flow rate over years. Spatial variations of the runoff quality are the key factor in non-point source pollution studies. This research investigates spatial variability of urban runoff quality parameters such as Total Phosphorous (TP), Total Nitrogen (TN), Suspended Solids (SS) and Biochemical Oxygen Demands (BOD) in relation to land use of urban catchments. In spatial analysis, stormwater will be sampled over the whole catchment area for a number of rainfall events during a year without any requirement to measure flow rate. This research showed comparable results for average pollutant concentrations with those of other urban catchments in Australia where traditional sampling method was used. The research outcomes will reliably estimate pollutants concentration for improved and efficient design of pollution control structures for each land use.

Non-uniform bird assemblages in urban environments : the influence of streetscape vegetation

The urban landscape encompasses a broad spectrum of variable environments ranging from remnant patches to highly modified streetscapes. Despite the expansion of urban environments, few studies have examined the influence of urbanization on faunal diversity, particularly in the Southern Hemisphere. In this study, four broad habitat types were recognized in the urban environment, representing a continuum of modification ranging from parks with remnant vegetation to streetscapes dominated by native vegetation and those dominated by exotic vegetation to recently developed streetscapes. Bird censuses were conducted at 36 sites throughout urban Melbourne, with nine sites surveyed in each habitat type. The four habitat types supported significantly different bird communities based on species richness, abundance and composition suggesting that bird assemblages of urban environments are non-uniform. Parks and native streetscapes generally supported fewer introduced species than exotic and recently developed streetscapes. Overall abundance and richness of species were lower in the exotic and recently developed streetscapes than in parks and native streetscapes. Significant differences were also observed in foraging guilds within the four habitat types, with parks having the most foraging guilds and recently developed streetscapes having the fewest. The transition from native to exotic streetscapes saw the progressive loss of insectivorous and nectarivorous species reflecting a reliance by these species on structurally diverse and/or native vegetation for both shelter and food resources. The implementation of effective strategies and incentives which encourage the planting of structurally diverse native vegetation in streetscapes and gardens should be paramount if avian biodiversity is to be retained and enhanced in urban environments. It is also critical to encourage the maintenance of the existing remnant vegetation in the urban environment.

Colonial designs: Thomas Karsten and the planning of urban Indonesia

Thomas Karsten (1885 – 1945) is undoubtedly a major figure in the history of architecture and town planning in Indonesia. Between 1915 and 1941 he was involved in town planning in 12 of the 19 municipalities and towns in Java (the most prominent exception being Surabaya) 3 of the 9 towns in Sumatra, and the only town in Borneo This paper does not attempts to investigate or question his importance in this field but to place his architectural and town planning ideas in the context of his broader politico-cultural ideas and activities in the Dutch East Indies between 1914 and 1942, and these, in turn, in the context of an evolving colonialism and colonial discourse.
