Green infrastructure needs green governance: Lessons from Australia’s largest integrated stormwater management project, the River Torrens Linear Park

The River Torrens Catchment in Adelaide has suffered from poor water quality and flooding for decades. To address these challenges, a green infrastructure project, specifically a Linear Park, was created within the catchment. Although the project has functioned reasonably well since its implementation, its complex nature poses several management challenges. Despite the scale of this project, there is little scholarly literature available. Hence, to analyse these management challenges, this paper reviews the original project documentation, as well as regulations and policy documents together with findings from interviews with key project informants. The aim is to investigate the key drivers for implementation; the major stakeholders involved; and the challenges emerging from the multidimensional attributes of the project. The challenges relate to the inconsistent and informal management structure, the involvement of multiple stakeholders, and pressure from surrounding development. The challenges are further grouped under four main themes, including communication and collaboration, project design goals, institutional and political frameworks, and planning and development regulations. This paper argues that green governance is the key to the successful implementation and management of sustainable green infrastructure projects. The findings from this case study can inform policymakers, planners and researchers to propose appropriate scenarios to manage urban stormwater and to reclaim neglected waterways. •Linear parks have emerged as an increasingly valuable green space typology.•The morphology of a linear park can present complex issues relating to governance.•The River Torrens Linear Park exhibits such complexities.•Green governance is essential for sustainable development of linear parks.
