Challenges to implementing urban sustainable stormwater management from a governance perspective: A literature review

Abstract

Abstract Conventional piped drainage systems are currently being challenged by climate change and urbanization, leading to pluvial flooding, with negative consequences for people's properties and lives. Sustainable stormwater management has been suggested as an alternative, but implementation of its infrastructures is often limited to demonstration zones. Governance factors are among the main reasons for the slow pace. A literature review analyzing 44 peer-reviewed papers was conducted to examine the challenges from a governance perspective. The challenges identified were summarized based on actors, resources, rules of the game, and discourses. Challenges such as unclear leadership and responsibilities, lack of funding, lack of cost data on sustainable stormwater management solutions, lack of space and knowledge, lack of uniform guidelines, and lack of stakeholder participation were found to be the most prominent reasons. Suggested solutions to overcoming these challenges include e.g., researchers acting as knowledge brokers, the involvement of social capital among local stakeholders, re-using vacant land, establishing uniform guidelines, and increasing market incentives to engage stakeholders. The governance structures of stormwater management were categorized as hierarchical, closed and open co-governance arrangements, while open co-governance arrangement was suggested as a useful governance structure. The difference is that the latter structure engages stakeholders, which is of benefits to increased sustainable stormwater management implementation. More research on social-economical aspects is suggested. These findings can improve understanding among decision makers and other relevant actors of challenges related to implementing sustainable stormwater management as a primary solution to the current climate and urbanization challenges.
