The health equity dimensions of urban food systems

There is increasing recognition that the nutrition transition sweeping the world’s cities is multifaceted. Urban food and nutrition systems are beginning to share similar features, including an increase in dietary diversity, a convergence toward “Western-style” diets rich in fat and refined carbohydrate and within-country bifurcation of food supplies and dietary conventions. Unequal access to the available dietary diversity, calories, and gastronomically satisfying eating experience leads to nutritional inequalities and diet-related health inequities in rich and poor cities alike. Understanding the determinants of inequalities in food security and nutritional quality is a precondition for developing preventive policy responses. Finding common solutions to under- and overnutrition is required, the first step of which is poverty eradication through creating livelihood strategies. In many cities, thousands of positions of paid employment could be created through the establishment of sustainable and self-sufficient local food systems, including urban agriculture and food processing initiatives, food distribution centers, healthy food market services, and urban planning that provides for multiple modes of transport to food outlets. Greater engagement with the food supply may dispel many of the food anxieties affluent consumers are experiencing.

Measuring food access in Melbourne: access to healthy and fast foods by car, bus and foot in an urban municipality in Melbourne

Access to healthy food can be an important determinant of a healthy diet. This paper describes the assessment of access to healthy and unhealthy foods using a GIS accessibility programme in a large outer municipality of Melbourne. Access to a major supermarket was used as a proxy for access to a healthy diet and fast food outlet as proxy for access to unhealthy food. Our results indicated that most (>80%) residents lived within an 8–10 min car journey of a major supermarket i.e. have good access to a healthy diet. However, more advantaged areas had closer access to supermarkets, conversely less advantaged areas had closer access to fast food outlets. These findings have application for urban planners, public health practitioners and policy makers.

Cervical cancer services for Indigenous Women: Advocacy, Community-Based Research and Policy Change in Australia

Collaborative research undertaken in the state of Queensland, Australia, resulted in major changes in cervical cancer screening and treatment for Indigenous women. Guided by an Indigenous statewide reference group and with an Indigenous researcher playing a lead role, qualitative data were collected using interviews, focus groups, and larger community meetings; and case studies were conducted with health workers and community members from diverse rural, remote and urban communities, to explore the different cultural and structural factors affecting understanding and awareness of cervical cancer and Indigenous women's use of and access to health services for screening, diagnosis and treatment. These data were supplemented by an analysis of clinical data and health service checklists. We discuss the methodology and summarize the key social and structural factors that discourage women from presenting for screening or returning for follow-up. These include women's misunderstanding of cervical cancer screening, fear of cancer, distrust of health services, poor recall and follow-up systems, and the economic and social burden to women presenting for treatment. We describe how the research process and subsequent activities provided Indigenous women with a vehicle for their own advocacy, resulting in important policy and program changes.

Unhealthy landscapes: policy recommendations on land use change and infectious disease emergence

Anthropogenic land use changes drive a range of infectious disease outbreaks and emergence events and modify the transmission of endemic infections. These drivers include agricultural encroachment, deforestation, road construction, dam building, irrigation, wetland modification, mining, the concentration or expansion of urban environments, coastal zone degradation, and other activities. These changes in turn cause a cascade of factors that exacerbate infectious disease emergence, such as forest fragmentation, disease introduction, pollution, poverty, and human migration. The Working Group on Land Use Change and Disease Emergence grew out of a special colloquium that convened international experts in infectious diseases, ecology, and environmental health to assess the current state of knowledge and to develop recommendations for addressing these environmental health challenges. The group established a systems model approach and priority lists of infectious diseases affected by ecologic degradation. Policy-relevant levels of the model include specific health risk factors, landscape or habitat change, and institutional (economic and behavioral) levels. The group recommended creating Centers of Excellence in Ecology and Health Research and Training, based at regional universities and/or research institutes with close links to the surrounding communities. The centers' objectives would be 3-fold: a) to provide information to local communities about the links between environmental change and public health ; b) to facilitate fully interdisciplinary research from a variety of natural, social, and health sciences and train professionals who can conduct interdisciplinary research ; and c) to engage in science-based communication and assessment for policy making toward sustainable health and ecosystems.

Measuring the walkability of local communities using geographic information systems data

Researchers are working to identify and promote environment and policy initiatives to encourage more active and healthy communities. Measuring environmental attributes through objective means can verify which physical environment factors are most important. We describe how Geographic Information Systems (GIS) may be used to measure objectively, the features of the built environment that may influence walking. We show how four key attributes currently believed to be of most relevance to walking for transport may be used to create a ‘walkability’ index. These are dwelling density (higher-density neighbourhoods support greater retail and service variety, resulting in shorter, walkable distances between facilities; driving and parking are more difficult); street connectivity (higher intersection density provides people with a greater choice of potential routes, easier access to major roads where public transport is available and shorter times to get to destinations); land use mix (the more varied the land use mix and built form, the more conducive it is to walk to various destinations); and net retail area (people who live near multiple and diverse retail opportunities are able to make more frequent and shorter shopping trips by walking and can walk to more local employment opportunities). The potential relationships between each of the objective environmental-attribute measures and walking behaviours is discussed, together with suggestions as to how such measures might be used to guide community infrastructure planning. GIS mapping can assist decision makers in where to focus transportation investments and where to guide future growth. Readily accessible GIS data can be used to guide and support urban planning and infrastructure investment decisions in both the private and public sectors, to increase walking in communities.

The Victorian living with possums policy : a review

Possums in urban areas can cause problems for residents when they live in the roof cavity of homes. The Victorian Living With Possums policy was implemented by the Department of Natural Resources and Environment (DNRE) in 1997 to address the ineffective, illegal and inhumane nature of possum management practices. Human-possum conflicts in urban areas can be difficult to resolve, and it is therefore important that the Living With Possums policy is effectively reaching the community and other stakeholders (e.g. vets, local councils).

This study represents Stage 1 of a two-part research project that aims to examine community awareness of and compliance with the policy and relevant legislation. A pilot questionnaire was designed and distributed to a sample of individuals who have recently hired possum traps from local councils or private organisations within metropolitan Melbourne. Preliminary findings indicate that although there is some level of awareness about the Living with Possums policy, there is evidence of non-compliance and a lack of understanding about the detailed policy guidelines. In Stage 2 of this project, questionnaires will be distributed to a larger sample of individuals who are experiencing conflicts with possums in order to examine just how widespread this lack of compliance and awareness is.

Examining the living with possums policy in Victoria, Australia : community knowledge, support and compliance

Studying the human dimensions of wildlife management issues is now considered to be an essential component
of wildlife research. This study examined the Living with Possums policy in Victoria, Australia, in terms of the policy’s
success in educating the community and ensuring community compliance. Postal surveys and telephone interviews
were conducted across three samples from Greater Melbourne. These samples included people who had experiences
with possums on their property (n = 340), veterinary clinics (n = 45) and the general public (n = 103). Significant
levels of non-compliance were uncovered, highlighting the need for a renewed public education campaign to take place
along with a continued interest in this issue from government agencies and councils. The study also revealed
discrepancies between the policy and public preferences for possum management, suggesting that a shift in the
recommended management technique may be warranted.

Evaluation of the implementation of a state government community design policy aimed at increasing local walking : design issues and baseline results from RESIDE, Perth Western Australia

Objectives.
To describe the design and baseline results of an evaluation of the Western Australian government's pedestrian-friendly subdivision design code (Liveable Neighborhood (LN) Guidelines).
Methods.

Baseline results (2003–2005) from a longitudinal study of people (n = 1813) moving into new housing developments: 18 Liveable, 11 Hybrid and 45 Conventional (i.e., LDs, HDs and CDs respectively) are presented including usual recreational and transport-related walking undertaken within and outside the neighborhood, and 7-day pedometer steps.
Results.

At baseline, more participants walked for recreation and transport within the neighborhood (52.6%; 36.1% respectively), than outside the neighborhood (17.7%; 13.2% respectively). Notably, only 20% of average total duration of walking (128.4 min/week (SD159.8)) was transport related and within the neighborhood. There were few differences between the groups' demographic, psychosocial and perceived neighborhood environmental characteristics, pedometer steps, or the type, amount and location of self-reported walking (p > 0.05). However, asked what factors influenced their choice of housing development, more participants moving into LDs reported aspects of their new neighborhood's walkability as important (p < 0.05).
Conclusions.

The baseline results underscore the desirability of incorporating behavior and context-specific measures and value of longitudinal designs to enable changes in behavior, attitudes, and urban form to be monitored, while adjusting for baseline residential location preferences.

An integrated model of subnational regional and urban economic development : framework of analysis

The mechanism of subnational regional and urban economic development has been studied extensively by economists, geographers, town planners and other academics. The existing widely varying theories of regional economic development are insufficient on their own in explaining how a region can develop and prosper. Each theory has evaluated a few facets of regional economic development. Research from these different perspectives is narrow and prevents any cross-fertilization of research from these diverse theories. Recognition of multiple factors affecting the development process has led the author to create an integrated model of regional and urban economic development. The essay first sets out to describe and explain this integrated model. Each of the components of this new model draws heavily upon seminal work in the field. This model proposes three rings. Each ring is at a different level of abstraction. The determinants of development described in each ring can influence each and every other determinant of development shown in the three-ring structure. This model recognizes that development in any centre, be it regional or urban, nascent or established, is a composite end result of the complex interplay of all the determinants. The essay then goes on to show how this model can provide a broad holistic approach to regional economic development that can assist researchers in their attempts to understand and link its various theories.

New residents—new city. The role of urban activists in the transformation of inner city Melbourne

This study of inner suburban residents' associations in Melbourne in the 1960s and 1970s examines the role of social activism in shaping Australia's urban dynamics. It argues that the focus on gentrification as an all-embracing explanatory concept in urban studies in Australia and elsewhere has detracted attention from the importance of structural change especially the de-industrialisation of the inner suburbs and the influence of urban activists and residents' associations in this period. The article concludes that insufficient analysis of social and economic change and the limited recognition of the importance of diverse communities continue to limit inclusive policy responses to urban reconstruction in Australia.

Endogenous transportation technology in a cournot differential game with intraindustry trade

We investigate a dynamic Cournot duopoly with intraindustry trade, where firms invest in R&D to reduce the level of iceberg transportation costs. We adopt both open-loop and closed-loop equilibrium concepts, showing that a unique (saddle point) steady state exists in both cases. In the open-loop model, optimal investments and the resulting efficiency of transportation technology are independent of the relative size of the two countries. On the contrary, in the closed-loop case firms’ R&D incentives are driven by the relative size of the two countries. Policy implications are also evaluated.

Sustainable living environment for urban low-income households in Malaysia : key factors for maintenance

Urbanisation is predicted to continuously increase every year. Demand for urban shelter will rise and hence this will force governments to act, within their capability, to provide affordable housing in order to maintain social and economic stability. Some industrialized countries have demonstrated full state support from planning and implementation through to continuing maintenance in order to create and sustain a healthy living environment for urban low-in-come households. For developing countries, this might be more difficult. Ensuring adequate maintenance to provide housing quality over the long term is proving even more problematic than simply providing housing. The question is how housing in developing countries can be made sustainable in order to provide a better living environment in the long term. This study focuses on key issues of residential living environments for urban low-cost housing in Malaysia in relation to housing maintenance management. Drawing from extensive primary research and a series of interviews, this exploratory study identifies factors that must be considered by policy makers in order to provide a decent and sustainable living environment for the urban lower-income group. The outcome suggests that current systems of maintenance management - offsetting maintenance to developers or the housing communities themselves, is not working well. The government may need to continue to support low cost housing through maintenance in order to prevent deterioration of accommodation that could become future slums.

Relative affordability

This research attempts to gauge the impact of "Melbourne 2030" policy on relative affordability within the Melbourne metropolitan area. Using price data over eight years, with reference to activity centre's and transport infrastructure. The results indicate this policy has, thus far, had little effect when measured at the suburb level.

Contributing to health reform : urban Aboriginal women speak out

In this thesis, the researcher shares their own personal journey as an Aboriginal researcher walking the borderlands between academic and Indigenous worldviews.  Indigenous Methodologies and Talking Circles provided a culturally safe environment for urban Aboriginal women to collectively develop and share their strategies to enable health care providers, educators, and policy makers to provide respectful non-racist, non-disciminatory health care.

The use of public transport in coastal Australia : modes of travel to work and greenhouse emissions

Commuting to work is one of the most important and regular routines of transportation in towns and cities. From a geographic perspective, the length of people’s commute is influenced, to some degree, by the spatial separation of their home and workplace and the transport infrastructure. The rise of car ownership in Australia from the 1950s to the present was accompanied by a considerable decrease of public transport use. Currently there is an average of 1.4 persons per car in Australia, and private cars are involved in approximately 90% of the trips, and public transportation in only 10%. Increased personal mobility has fuelled the trend of decentralised housing development, mostly without a clear planning for local employment, or alternative means of transportation. Transport sector accounts for 14% of Australia’s net greenhouse gas emissions. Without further policy action, Australia’s emissions are projected to continue to increase. The Australian Federal Government and the new Department of Climate Change have recently published a set of maps showing that rising seas would submerge large parts of Victoria coastal region. Such event would lead to major disruption in planned urban growth areas in the next 50 years with broad scale inundation of dwellings, facilities and road networks. The Greater Geelong Region has well established infrastructure as a major urban centre and tourist destination and hence attracted the attention of federal and state governments in their quest for further development and population growth. As a result of its natural beauty and ecological sensitivity, scenarios for growth in the region are currently under scrutiny from local government as well as development agencies, scientists, and planners. This paper is part of a broad research in the relationship between transportation system, urban form, trip demand, and emissions, as a paramount in addressing the challenges presented by urban growth. Progressing from previous work focused on private cars, this present paper investigates the use of public transport as a mode for commuting in the Greater Geelong Region. Using a GIS based interaction model, it characterises the current use of the existing public transportation system, and also builds a scenario of increased use of the existing public transportation system, estimating potencial reductions in CO2 emissions. This study provides an improved understanding of the extent to which choices of transport mode and travel activity patterns, affect emissions in the context of regional networks. The results indicate that emissions from commuting by public transportation are significantly lower than those from commuting by private car, and emphasise that there are opportunities for large abatment in the greenhouse emissions from the transportation sector related to efforts in increasing the use of existing public transportation system.
