Alternative water strategies in public domains : innovative strategies in progress along North Terrace, Adelaide

Water sensitive design on our urban threshold is increasingly becoming topical. In Adelaide it is being driven by stormwater management strategies and economic efficiencies in a city that is beginning to embrace its Mediterranean environment, low water sustainability, and whether our showpiece public domains in Adelaide can afford large expanses of manicured lawns.

This paper reviews four projects in progress along the North Terrace in Adelaide. The first involves a major redesign of First Creek as it traverses Adelaide Botanic Garden to address stormwater management issues. The redesign includes strategies to control flash flooding, to cleanse stream water from pollutants, and to carefully incorporate a wetland system as an integral botanical and horticultural feature of a botanic garden. Further down North Terrace, the University of Adelaide is evaluating a scenario that will totally redesign Goodman Crescent, its picture-postcard promenade lawn. The scenario is to host an integrated water retention and water purification and cleansing system that will service independently of mains water an irrigation system and a waterfall. The proposal draws upon a similar strategy recently adopted by the South Australian Museum to capture and cleanse surface and roof water but place the installation and process on display as part of its overall biodiversity museum display that will unfold over the next five years under director Tim Flannery. The fourth example, in process at present, is to devise an integrated water system that may enable the Government House grounds to remove itself from dependence upon costly mains water to totally sustain its extensive gardens and lawns.

Importantly each project has similar threads: creative water maximization and purification use, and a desire to place these ‘installations’ on display as public statements of their commitment to water sustainability in Adelaide. But radically, here are four prominent cultural institutions readily willing to redefine the notion and traditional visual imagery of a ‘wetland’ on what is the main cultural boulevard of a capital city.

Garden & landscape heritage:a crisis of tangible & intangible comprehension and curatorship

The cultural landscape of George Town, Penang, Malaysia, embraces the historic enclave of George Town as well as a range of other significant colonial vestiges adjacent to the entrépôt. Many of these landscapes cannot be isolated from the énclave as they are integral to and part of its cultural mosaic and character. Perhaps the most important are the Penang Hill hill-station landscape and the 'Waterfall‘ Botanic Gardens. The latter is an under-valued 'garden of the empire‘—a garden that significantly underpinned the development and historical and botanical stature of the Singapore Botanic Gardens.This paper reviews the cultural significance of colonial botanic gardens as they were established around the world during the scientific explosion of the late 1800s. It addresses their position within World Heritage listings, and considers the role, significance and importance of the 'Waterfall‘ Botanic Gardens within this context, within the concept of 'cultural landscapes‘, and critiques its absence from the recent World Heritage Listing of the colonial enclaves of Georgetown and Meleka in Malaysia.

The victories of failure: C. J. Degaris and his Corio garden suburb

Mildura's Clement John De Garis (1884 - 1926) was renowned in his lifetime as an entrepreneur, promoter of Australian literature, publicist, pioneering aviator, author, lyricist, orator, dramatist, irrigationist, newspaper proprietor, magazine editor, land developer and most importantly, a visionary.

'Particularly happy' arrangement?: Idealism, pragmatism and the enclosed open spaces of Perth garden suburbs

One of the hallmarks of many planned garden suburbs of the early twentieth century is the internal reserve: open space at the rear of residences, without street frontage. An idealistic conception with direct links to overseas planning theory, these spaces were not always well received by either local councils or residents; despite this, many survive today as legacies of early suburban reformism. Perth’s highest-profile planning advocates of the interwar years, most notably town clerk William Bold and the progressive surveying  partnership of Hope and Klem, embraced and encouraged the idea and a number of middle-ring suburbs in Perth feature internal reserves which have survived both encroachment and resubdivision. Some have been given heritage status in recognition of their importance to the history and fabric of particular suburban communities; others remain neglected and essentially unacknowledged. All raise ongoing usage, maintenance and management issues for the councils that have inherited them.

Pyrite framboids interpreted as microbial colonies within the Permian Zoophycos spreiten from southeastern Australia

Two types of pyrite framboids (PF, probably sulphate-reducing bacteria) have been found
within the Zoophycos spreiten, hosted in the Guadalupian (Middle Permian) glaciomarine greywacke
of the Westley Park Sandstone Member within the Broughton Formation from the southern Sydney
Basin of southeastern Australia. They are composed of non-sheathed (PF1) and sheathed (PF2)
sub-micron balls, respectively. Chemically, the sub-micron balls consist of iron, sulphur, carbon and
oxygen. Both PF1 and PF2 occur in rhythmic alternationwithin the thick, light-grey and thin, dark-grey
minor lamellae of Zoophycos spreiten. The framboids from the minor lamellae are highly abundant and
occur in an orderly arrangement of equal density and in a good state of preservation.Within Zoophycos
spreiten no homogeneous filling, fecal pellets, or any sign of re-exploitation of the minor lamellae have
been recognized. No similar framboids have been observed outside Zoophycos spreiten. Therefore, the
framboids are interpreted as the pyritized remains of microbial colonies within Zoophycos spreiten.
The trace Zoophycos would be a multifunctional garden thatmay have been carefully constructed by the
Zoophycos maker, where different microbial colonies were orderly and carefully planted and cultured
within different minor lamellae. Further, it is proposed that the Zoophycos maker had a symbiotic
relationship with microbial colonies on the mutual basis of food supply and redox conditions. The fact
that the overlying spreiten cut the underlying ones indicates that the Zoophycos from the study area is
of an upward construction. The rhythmic alternation of both the thick, light-grey and thin, dark-grey
minor lamellae within Zoophycos spreiten may be suggestive of a gardening manner of the Zoophycos
maker responding to the warm and cold changes, food supply in pulses and variations of sedimentation
rate for planting and culturing microbial colonies under the conditions of a glaciomarine environment
at the high latitudes.

Cultivating health and wellbeing : members' perceptions of the health benefits of a Port Melbourne community garden

This paper reports on a research project undertaken with members of a community garden in Port Melbourne, Australia, to investigate the ways in which such a facility contributes to the enhancement of health, wellbeing and contact with nature for urban dwellers. Ten members from an urban community garden were interviewed using qualitative semi-structured questions exploring perceptions of health and wellbeing benefits associated with membership. The garden was felt by members to be a sanctuary where people could come together and escape daily pressures, a source of advice and social support, and a place which gave them a sense of worth and involvement. Members also identified spiritual, fitness and nutritional benefits arising from participation in the community garden. It is evident even from this small qualitative study that community gardening offers many health and wellbeing benefits to members. This study provides a basis for the benefits of community gardens in Australia to be taken into account by policy-makers and practitioners to enhance urban community health and wellbeing.

Leading lights : the promotion of garden suburb plans and planners in interwar Australia

This thesis explores interwar town planning in Australia, focusing on the period of large-scale urban expansion in the 1920’s. It problematises aspects of Australia’s urban planning history, particularly the 1920s ‘garden suburb. It also investigates the question of the use of international planning ideas in Australia, and the assertion or creation of authority by the Australian planning movement. The thesis additionally investigates the use of authoritative planning rhetoric for commercial or creative advantage. The thesis argues that the majority of innovative planning projects in the interwar years took place in the formation and foundation of the garden suburb. It shows that the garden suburb – assumed in much planning history to be an inferior form of Ebenezer Howard’s ‘garden city’ ideal – has, in fact, a number of precedents in 19th century Australian suburbia, some of which were retained in 20th century commercial estate design. Much of the Australian town planner’s authority at this time required recognition and awareness of the interests and needs of the general public, as negotiated through land vendors. As Australians looked to the future, and to the US for guidance, they were invited to invest in speculative real estate development modelled on this vision. The thesis concentrates primarily on the lives, careers and work of the British-Australian architect-planner Sir John Sulman; the Chicagoan architect-planners Marion Mahony and Walter Burley Griffin; and the Australian surveyor-planner Saxil Tuxen. These individuals were among the most prominent planners in Australia in the interwar years. All designed Australian garden suburbs, and combined advocacy with practice in private and public spheres. The thesis examines images and personas, both generic and individual, of the planner and the vendor. It shows that the formulation of the garden suburb and design practices, and the incorporation of international elements into Australian planning, are important in the creation of planning practice and forms. It also outlines the way these continue to have significant impact, in diverse and important ways, on both the contemporary built environment and planning history itself.
