The dynamic challenges of mainstreaming water sensitive cities in our built environment: Lessons from Australia

Abstract

Stormwater has been acknowledged as a major concern in cities because of mismanagement of this resource. It has also been underestimated as a resource in climate change actions and policies. Water sensitive urban design (WSUD) is considered as an effective adaptation measure to address these issues while providing many co-benefits. This paper reports the challenges of implementing WSUD in the Australian context. Semi-structured interviews were conducted with 57 experts in Australia. The experts are involved in design, research, engineering, and planning policy in both public and private sectors. The qualitative analysis of the interviews involved thematic and content analysis through NVivo12. Analysis of the responses indicated six main challenges including financial, innovation and evaluation tools, capacity, institutional arrangements, and policy. The experts believe that a lack of standardized design and implementation can be addressed through collaborative design processes. They suggest a robust structure of approval process and establishing clarity of roles and responsibilities in all sectors. All respondents confirm the critical role of monitoring and maintenance in these projects. It is suggested that allocating recurrent funding for these ongoing activities from the beginning and setting incentives to engage communities and local councils in maintaining the projects can be helpful.
