Moreover, decision-makers have acknowledged and addressed social values, biodiversity, and habitat connectivity in policy documents. Canberra in the Australian Capital Territory (ACT), is a unique Australian city since it is totally designed as the National Capital of Australia and is built on a grassland plain, inspired by the Garden City concept. The green and open spaces have a symbolic value, representing Canberra as the national capital. However, Canberra is experiencing increasing urban development pressure, which threatens its green and open spaces. Thus, it is critical to explore the GI status in governance and decision-making in Canberra to guide its future planning. This research explores ten policy documents using a reflexive analysis to interpretatively critique policy documents and to diagnose the existing opportunities and constraints in Canberra’s GI planning. The documents were selected from 4 main defined scopes, Australian Government land-use responsibilities, ACT Government land-use planning and strategy, ACT Government greenspace planning, and Tree management regulations and mechanisms. This research identified dual governance (national/territory) and dual nature character (native/exotic) in the policy documents, which has intensified the complexity of GI planning. Another constraint was the lack of district level planning and a structured bottom-up approach. More flexibility in governance and collaboration between different governance levels and agencies is needed to make a more effective GI network, using the existing opportunities such as open space systems. Although GI principles have been addressed at Canberra’s strategic level, more comprehensive GI planning is needed to address all types of greenspaces."}],"$":{"view":"all","id":"abs0010"},"#name":"abstract-sec"}],"$":{"view":"all","id":"ab0010","class":"author"},"#name":"abstract"}],"$":{"xmlns:ce":true,"xmlns:dm":true,"xmlns:sb":true},"#name":"abstracts"},"pdf":{"urlType":"download","url":"/science/article/pii/S1618866722001716/pdfft?md5=585d501bacb22509f49382fe54a4422d&pid=1-s2.0-S1618866722001716-main.pdf"},"iss-first":"","vol-first":"74","isThirdParty":false,"issn-primary-unformatted":"16188667","issn-primary-formatted":"1618-8667"},{"pii":"S1618866722001777","journalTitle":"Urban Forestry & Urban Greening","publicationYear":"2022","volumeSupText":"Volume 74","articleNumber":"127634","pageRange":"127634","trace-token":"AAAAQGg-Q53MTiazxoVELOJiBAmBukQIuYF-0WP86B9lBpl-MytKYMmfKU3VLUnQphG6kpZSfiFc1d3aXKGOH2y3rFjsAca-VIsQxyE3_0OS8BRE9w-a8g","authors":{"content":[{"#name":"author-group","$":{"id":"ag0005"},"$$":[{"#name":"author","$":{"id":"au0005","author-id":"S1618866722001777-07d1a2b40ffc1c0abf960fa7cde49bda"},"$$":[{"#name":"given-name","_":"Shinjita;Geospatial Sciences, School of Science, STEM College, RMIT University, GPO Box 2476V, Victoria 3001, Australia;School of Tourism and Geography Science, Qingdao University, Qingdao 266071, China;Department of Architecture, University of Pretoria, Bag X 20 Hatfield, Pretoria 0028, South Africa;Green Infrastructure Research Labs (GIRLS), Cities Research Institute, Griffith University, 170 Kessels Road, Nathan, 4111 Queensland, Australia;The Martin Centre for Architecture, Department of Architecture, University of Cambridge, Cambridge CB2 1PX, UK

摘要: Globally, there is growing recognition of the potential of road verges to contribute to urban greening and ecosystem service provision, beyond their original functions of utility provision and public access. Numerous, diverse stakeholders are involved in their management, yet their shared and diverging perspectives on verge greening are poorly understood. This research examined the perspectives on road verge greening by 30 respondents from eight stakeholder groups from the Perth Metropolitan Area, Australia. Stakeholders spanned local and state governments, developers, peak bodies, utility providers, environmental consultants, verge treatment providers and urban greening advocates. Semi-directed interviews and Likert scales were used to assess respondents' perspectives and perceived importance of urban verge functions and ecosystem services, risks and challenges associated with verge greening, and preferred verge vegetation composition. The most important ecosystem services for all stakeholders were temperature regulation (through the provision of street trees), those associated with water management and aesthetically interesting streetscapes. Perceived challenges included limited knowledge for the management of native species verges and streetscapes, organisational costs for verge managers and utility providers, and the need to engage with multiple local government authorities with widely varying management and financial valuation of verge vegetation. Stakeholders’ preferred verge reflected diverse uses, local characteristics, and was climate and water resilient (particularly ‘waterwise’). A majority of stakeholder groups felt greater attention to the ‘understorey’ of the ‘urban forest’ was warranted. An emerging perspective across four stakeholder groups identified the potential for verges to grow a local ‘sense of place’, through plantings emphasising local native species and highlighting local Whadjuk Noongar seasons. These findings support policies and programmes associated with urban greening, and assist in navigating the contestation often associated with new or transformative uses of land at the public-private interface.
