Shocking the Suburbs: Urban Location, Homeownership and Oil Vulnerability in the Australian City

Energy security is receiving increasing attention from governments and scholars at the global and national scale. Petroleum security and rising fuel prices are a challenge for cities whose housing systems are highly dependent on automobile transport. This study assesses transport and socio-tenurial patterns within Australian cities to identify how the combined present and future effects of rising fuel costs, mortgage interest rates and general inflation will be spatially distributed. Using an ‘oil vulnerability’ assessment methodology based on Australian Census data, the study reveals broad-scale mortgage and oil vulnerability across the outer suburbs of Australian cities. The paper concludes with some observations about spatially equitable policy responses to ameliorate the housing and urban impacts of rising petroleum costs.

A GIS‐based land use and public transport accessibility indexing model

Accessibility indexing is important in evaluating existing land use patterns and transportation services, predicting travel demands and allocating transportation investments. A GIS-based land use and public transport accessibility indexing model has been developed for measuring and mapping levels of accessibility to basic community services by walking and/or public transport, within local government areas. The model aims to assist the planning and decision making process to deliver integrated land use and transportation outcomes. It is an origin-based accessibility model that determines levels of accessibility by utilising GIS analysis techniques to measures accessibility based on both actual walking distances and public transport travel time. The model has been applied to two pilot studies in the Gold Coast City to assess its practicality and effectiveness. This paper outlines the methodology of the model and the findings related to these pilot studies. The paper also demonstrates benefits and application of the model to other urbanised local government areas.

Challenges in using geographic information systems (GIS) to understand and control malaria in Indonesia

Malaria is a mosquito-borne disease of global concern with 1.5 to 2.7 million people dying each year and many more suffering from it. In Indonesia, malaria is a major public health issue with around six million clinical cases and 700 deaths each year. Malaria is most prevalent in the developing countries of the world. Aid agencies have provided financial and technical assistance to malaria-prone countries in an effort to battle the disease. Over the past decade, the focus of some of this assistance has been in the provision of geographic information systems (GIS) hardware, software and training. In theory, GIS can be a very effective tool in combating malaria, however, in practice there have been a host of challenges to its successful use.This review is based, in part, on the literature but also on our experience working with the Indonesian Ministry of Health. The review identifies three broad problem areas. The first of these relates to data concerns. Without adequate data, GIS is not very useful. Specific problem areas include: accurate data on the disease and how it is reported; basic environmental data on vegetation, land uses, topography, rainfall, etc.; and demographic data on the movement of people. The second problem area involves technology – specifically computer hardware, GIS software and training. The third problem area concerns methods – assuming the previous data and technological problems have been resolved – how can GIS be used to improve our understanding of malaria? One of the main methodological tools is spatial statistical analysis, however, this is a newly developing field, is not easy to understand and suffers from the fact that there is no agreement on standard methods of analysis.The paper concludes with a discussion of strategies that can be used to overcome some of these problems. One of these strategies involves using ArcView GIS software in combination with ArcExplorer (a public domain program that can read ArcView files) to deal with the problem of needing multiple copies of GIS software. Another strategy involves the development of a self-paced training package that can be used to train individuals

Performance-based planning - Perspectives from the United States, Australia, and New Zealand

This article examines the application of performance-based planning at the local level in the United States, Australia, and New Zealand. A review of the literature finds that there have been few evaluations of performance-based planning, despite its being used by many governments. The authors provide a comparative review of the experiences of various jurisdictions in implementing this form of zoning and present observations on its relative strengths and weaknesses. Findings suggest that many of the jurisdictions that adopted performance-based planning subsequently abandoned it because of the heavy administrative burden required, and where performance methods survived, they were typically hybridized with traditional zoning. If performance-based approaches continue to be used, there is a need to better understand the administrative and implementation implications of this type of land use regulation.

Green around the gills? The challenge of density for urban greenspace planning in SEQ

Abstract Australian cities exhibit a quality of life arguably among the best in the world, but rapidly expanding populations may soon threaten this status. The burgeoning conurbation of South East Queensland (SEQ) is an example. Recent growth management policies and plans (e.g. South East Queensland Regional Plan and local authority growth management strategies) have sought to curtail urban sprawl through urban footprints, growth management boundaries, urban consolidation, and other measures. The ‘density imperative’ presented by these collective urban policies affects the sourcing, provision and management of open space in inner-city locales in SEQ which may soon run out of land for parks and urban greenspace. This paper presents results from recent research into the environmental equity dimensions of providing urban greenspace in SEQ. Critiquing the long-entrenched parks-standards approach, the paper offers a ‘needs-based’ alternative, and considers its utility for SEQ and other fast-growing Australian urban areas. Questioning orthodox planning perspectives about who lives in higher density areas, we argue that local and state governments should look towards a variety of new types of green and open space to meet the needs of existing and future residents living in denser built environments.

An Empirical Analysis of Environmental Mediation

Abstract The use of mediation for resolving environmental disputes has grown rapidly over the past several decades. This is due, in part, to claims made by advocates of the mediation process that it is superior to litigation and administrative hearings for the resolution of public policy disputes. However, there has been little empirical research to test these claims. This five-year study of the Florida Department of Environmental Protection tests two of these claims. First, does mediation result in higher settlement rates, as compared to traditional dispute resolution processes? Second, are mediation settlements carried out more often than are the settlements reached through traditional processes?

Environments for Healthy Living (EFHL) Griffith birth cohort study: background and methods.

The health of an individual is determined by the interaction of genetic and individual factors with wider social and environmental elements. Public health approaches to improving the health of disadvantaged populations will be most effective if they optimise influences at each of these levels, particularly in the early part of the life course. In order to better ascertain the relative contribution of these multi-level determinants there is a need for robust studies, longitudinal and prospective in nature, that examine individual, familial, social and environmental exposures. This paper describes the study background and methods, as it has been implemented in an Australian birth cohort study, Environments for Healthy Living (EFHL): The Griffith Study of Population Health. EFHL is a prospective, multi-level, multi-year longitudinal birth cohort study, designed to collect information from before birth through to adulthood across a spectrum of eco-epidemiological factors, including genetic material from cord-blood samples at birth, individual and familial factors, to spatial data on the living environment. EFHL commenced the pilot phase of recruitment in 2006 and open recruitment in 2007, with a target sample size of 4000 mother/infant dyads. Detailed information on each participant is obtained at birth, 12-months, 3-years, 5-years and subsequent three to five yearly intervals. The findings of this research will provide detailed evidence on the relative contribution of multi-level determinants of health, which can be used to inform social policy and intervention strategies that will facilitate healthy behaviours and choices across sub-populations.

Investigating the social dimensions of transport disadvantage: I. Towards new concepts and methods

This article is the first of two papers that engage critically and productively with the relationship between the socio-economic transformations of cities, the differentiation of vulnerable groups within urban space and the distribution of transport services. This article undertakes a comprehensive review of the major conceptual and methodological approaches by which scholars and policy researchers have sought to address the connection between social disadvantage and access to transport. The article critically assesses the relative merits of various spatial analytical methodologies in illuminating social–transport links. The study finds that there is a need for greater sophistication in the use of analytical methods in transport research as well as an imperative for greater sensitivity to social differentiation within urban areas and relative to infrastructure and services. The article concludes by developing a method for combining spatial social and transport service data that is then deployed in the empirical case study reported in the second paper.

Travel Self-Containment in Master Planned Estates: Analysis of Recent Australian Trends

Low density suburban development and excessive use of automobiles are associated with serious urban and environmental problems. Master planned development suggests itself as a possible palliative for these ills. This study examines the patterns and dynamics of movement in a selection of master planned estates in Australia with the aim of developing new approaches for assessing the containment of travel within planned development. A geographical information systems methodology is used to determine regional journey-to-work patterns and travel containment rates. Factors that influence self-containment patterns are estimated with a regression model. The findings of the pilot study demonstrate that the proposed model is a useful starting point for a systematic and detailed analysis of self-containment in master planned estates.

Investigating the Social Dimensions of Transport Disadvantage II: From Concepts to Methods through an Empirical Case Study

This article is the second of two papers that review the field of spatially sensitive social scientific research into the links between social status and transport disadvantage. The first paper undertook a comprehensive review of the social scientific and transport planning literature to mark the level of development in the field and identify conceptual and methodological issues and constraints in this field of inquiry. The present article supports the advancement of socially and geographically sensitive transport research by opportunities for the development of more sophisticated spatial analytical methodologies. The approach we present is able to account for factors not previously addressed in either social or transport planning research, in particular the temporal dimensions of transport service accessibility. The article articulates the methodology through an empirical case study of socio-spatial transport disadvantage within the Gold Coast City. The article demonstrates that there are important theoretical and practical lessons to be gained for researchers and policy makers in addressing the social dimensions of transport and infrastructure provision. Further, the article argues that an attentiveness to new ways of combining and representing social and transport data-sets can promote policy relevant empirical social inquiry. The article also contributes in a productive way to the empirical knowledge of Australias sixth-largest metropolitan area, which is often overlooked by urban scholars.
