200 Mile City


MERGING CITIES THREATEN LANDSCAPE & LIFESTYLE


The distinctive regional landscape and urban identity of Australia’s eastern seaboard is under threat of being overwhelmed by metropolitan sprawl, for example a South East Queensland ‘mega-city’ stretching from Noosa to the Tweed River.

Sustainable development and ‘the 200 mile city’ was the central issues at The Australian Institute of Landscape Architects (AILA) National Conference held in Brisbane from September 28 to October 2 in 2004.

The conference titled, ‘200 mile city… designing a sustainable urban future’, put sustainable urban planning on the agenda, addressing the issue of merging cities, the social and environmental costs, and creative and sustainable responses to these challenges.

Urban conglomerates are in evidence in many parts of Australia, the broader Asia Pacific region and throughout the world. Even where a capital city ‘core’ is buffered from satellite towns and commuter suburbs by green belts, modern transport, media and communications are effectively creating integrated mega-cities.

At the AILA Conference, national and international leaders presented papers on new city forms, new approaches to the environment and new collaborative partnerships, as well as a range of ‘best practice’ projects

The region surrounding Brisbane and Moreton Bay, which is justly famous for its biodiversity, scenery, tourist attractions and ‘liveability’, is a great example of the issues we face. Environmental resources and social values are at risk from the infrastructure, suburban sprawl and widespread ‘sameness’ associated with rapid urban growth. The likely future scenario is an urban conglomerate spreading hundreds of kilometres, subsuming smaller communities and demanding ever-greater resources for its ‘footprint’.\

Author Deyan Sudjic alerted the planning and design professions and social commentators to these world-wide trends in 1992 with his book “The 100 Mile City”, and it appears that his predictions are being realised in coastal south-east Queensland. Current growth rates and development trends threaten to overwhelm traditional planning and control approaches, and new responses are required.

As growth and sprawl threaten to envelope some of Australia’s most valuable assets – its coastal landscape, natural environment, open spaces and local communities – we need new ways of developing and integrating city forms. Landscape architects are part of a successful team approach which make our cities liveable and legible.

To maintain quality of life in our large cities, developers, planners, governments and landscape architects are addressing these issues now.
