Canberra, a city known as a “garden city” that emerged in the early twentieth century, is developing at a speedy rate. The compact city vision for Canberra was announced in ACT Planning Strategy 2018 while the city encounters climate change impacts. Although urban compaction has its own benefits, it is considered a challenge for maintaining and developing the quality and quantity of urban green spaces. Canberra owns a unique urban design legacy and is known for its bush capital/garden city character, which has intertwined the social and ecological layers of the city. The concern around urban compaction and densification calls for holistic green infrastructure (GI) planning to balance the built and non-built infrastructure. To do so, it is necessary to understand the underlying social-cultural and ecological layers of Canberra’s green spaces and the Ecosystem Services (ESS) they offer. The application of multiple ESS in the current GI planning and governance practices is another issue that needs to be examined to inform future development. Thus, this qualitative research seeks to understand the ESS discourses in Canberra’s GI and the challenges in applying these ESS in planning and governance. We used a socio-ecological approach to design the research and understand the multidimensional values and benefits of Canberra’s green spaces. We adopted semi-structured interviews with twelve experts from relevant disciplines with specific knowledge of Canberra’s urban landscape and green spaces to find out the socio-ecological synopsis of Canberra’s GI and green spaces governance. We found that it is necessary to mainstream multiple ESS in Canberra’s GI to amplify the existing socio-ecological values. The abundance of green spaces in Canberra can be better used to make a multifunctional landscape that serves multiple ESS. However, we identified the maintenance and budget issues as the main challenges that can be addressed by improving community engagement. To design an effective GI network and mainstream ESS in green spaces, the planning and governance system should employ a transdisciplinary, multi-object and multi-scale approach and state-of-the-art technologies. Moreover, this research underlined the importance of a protocol and guidelines that monitor the landscape projects’ design and delivery correspondence to the high-level policies. |
