Community mix, affordable housing and metropolitan planning strategy in Melbourne

Income segregation across Melbourne’s residential communities is widening, and at a pace faster than in some other Australian cities. The widening gap between Melbourne’s rich and poor communities raises fears about concentrations of poverty and social exclusion, particularly if the geography of these communities is such that they and their residents are increasingly isolated from urban services and employment centres. Social exclusion in our metropolitan areas and the government responses to it are commonly thought to be the proper domain of social and economic policy. The role of urban planning is typically neglected, yet it helps shape the economic opportunities available to communities in its attempts to influence the geographical location of urban services, infrastructure and jobs. Under the current metropolitan strategy ‘Melbourne 2030’ urban services and transport infrastructure are to be concentrated within Principal Activity Centres spread throughout the metropolitan area and it is the intention that lower-income households should have ready access to these activity centres. However, the Victorian state government has few housing policy instruments to achieve this goal and there are fears that community mix may suffer as house prices and rents are bid up in the vicinity of Principal Activity Centres, and lower-income households are displaced. But are these fears justified by the changing geography of house prices in the metropolitan region? This is the key research question addressed in this paper which examines whether the Victorian practice of placing reliance on the market to deliver affordable housing, while intervening to promote a more compact pattern of urban settlement, is effective.

Renewable energy education : Report from a field trip to Melbourne, Australia, and short visits to India and New Zealand During Nov/Dec 1992

During November and December 1992 I visited several groups involved with renewable energy, most of them dealing with education. These groups and their work are described briefly in this report. The groups in Melbourne, Australia have come a long way with education in this field and we have a lot to learn from them. Government funding is needed for large scale work, but useful work can still be done at the community level with much smaller budgets.

Urbanisation and the ecology of powerful owls ninox strenua in outer Melbourne, Victoria

Historically, the Powerful Owl (Ninox strenua) has been seen as a southeastern Australian species restricted to, or most numerous in, dense gullies of tall open forests in hilly or mountainous areas of the coast and Great Divide. However, recent research has revealed that Powerful Owls may breed numerously and successfully in a wider range of habitats than previously believed, including the forests and woodlands within the metropolitan areas of some major cities.Here we report on the breeding of a number of pairs of Powerful Owls in the Yarra Valley, Victoria. Study sites ranged from relatively undisturbed, wet sclerophyll forest 80 km from central Melbourne, through dry sclerophyll, eucalypt-dominated open forest with some disturbance, to a highly disturbed urban parkland only 18 km from central Melbourne. We found that Powerful Owls breed successfully in some urban areas, but are limited in the amount of human disturbance they can tolerate near their nesting hollow. In the most heavily utilized section of the urban parkland, all breeding attempts were unsuccessful and in one year the young were apparently eaten by one of the parents. This followed construction of a timber boardwalk under the nest tree during the breeding season. The Powerful Owls subsequently moved to a more secluded nesting hollow and raised two young. Recommendations for management of Powerful Owls in urban areas are discussed in the context
of these results.

Interpreting changes in heroin supply in melbourne: droughts, gluts or cycles?

In this Harm Reduction Digest Paul Dietze and John Fitzgerald provide another possible way of understanding what has come to be referred to as Australia's heroin 'drought'. They examine evidence from Melbourne, Victoria and suggest that the apparent downturn in heroin availability in 2000 may, in part, be the result of an end of a heroin 'glut' and that perceptions of this phenomenon may be coloured by the development of more sophisticated indicators of the heroin market. They conclude with claims that the reasons for the reduction in drug consumption and adverse health outcomes, such as those attributed to interdiction, are thus premature.

Refugees and residents: densities and habitat preferences of lorikeets in urban Melbourne

Lorikeet densities were measured across four habitat types in urban Melbourne. Musk Glossopsitta concinna and Rainbow Lorikeets Trichoglossus haematodus were shown to preferentially use established streetscapes with predominantly native vegetation. The high densities of Musk Lorikeets recorded possibly reflect a paucity of flowering in Victorian BoxIronbark forests during the autumnlwinter of 2002 and the availability of supplementary nectar resources in the urban environment. Future planting decisions in recently developed streetscapes will dictate the long-term resource potential for lorikeets and other nectarivores in urban Melbourne.
