Understanding Urban Green Spaces Typology’s Contribution to Comprehensive Green Infrastructure Planning: A Study of Canberra, the National Capital of Australia
Abstract
The urban densification agenda for the Australian Capital Territory announced in 2012 as well as the climate-related impacts (such as flood and rising temperature) have made the role of green infrastructure in this city more critical than at any other time. The Living Infrastructure Plan for Canberra was proposed by the local government in 2019 and it is currently being developed. However, there is a lack of understanding of the variety of urban green infrastructure characters, associated urban green space types, and their contributions to the green infrastructure plan. Therefore, this research aims to study the existing types of urban green infrastructure and green spaces in Canberra and investigate their potential sociocultural and ecological contributions that need to be considered in developing green infrastructure plans. To achieve this, we employed a socioecological approach and a mix of methods including a literature review, a review of policy documents, semi-structured interviews with experts, geospatial data, and field observation. Ten main urban green infrastructures were identified in Canberra and associated green spaces and their ecosystem services were discussed. Finally, a framework was delineated to suggest recommendations for the identified urban green infrastructure types with the aim of improving the green infrastructure planning practice by enhancing, preserving, and reinforcing green spaces. The findings provide a foundation for coordinating green infrastructure decision making and suggest a framework for designing high-quality and multifunctional green spaces. The study concludes that further investigation is required to comprehend the diversity of urban green infrastructures and their ecosystem services, co-benefits, synergies, and trade-offs.
