Abstract

Conventional stormwater management systems have been criticised as being unsustainable due to increased flood risks downstream and water quality degradation in the receiving water bodies. Use of green infrastructure to manage stormwater has long been suggested, but implementation is still mainly limited to pilot projects. Based on a systematic literature review and two qualitative case studies, governance challenges and their interdependencies influencing implementation of sustainable stormwater management (SSM) were examined.

In the literature review, nineteen governance challenges hindering SSM implementation from a global perspective were identified. Case study 1 examined governance factors influencing SSM implementation from a local perspective under two distinct governance structures, namely, hierarchical in China and non-hierarchical in Sweden. Governance factors found to influence SSM implementation were mapped into causal loop diagrams (CLD) to describe the governance factor interdependencies. Case study 2, investigating the Sponge Cities initiative in China, identified governance challenges influencing a national SSM policy being implemented locally. It was found that conventional grey infrastructure still plays a significant role in the Sponge Cities initiative due to lack of space, a general lack of knowledge of SSM and prioritization of quantifiable objectives within a short time-frame.

The thesis provides an overview of governance challenges and their interdependencies influencing SSM implementation, as well as a visual tool (SSM-CLDs) to help local authorities and non-governmental stakeholders understand the complexities of SSM from a governance perspective.

Konventionella dagvattensystem har kritiserats för att leda till ökad risk för
översvämning nedströms och försämrad vattenkvalitet i recipienterna. Hållbar hantering
av dagvatten genom blågröna lösningar har funnits på agendan länge, men
implementeringen är fortfarande huvudsakligen begränsad till pilotprojekt.
Avhandlingen undersöker hur utmaningar och deras beroendeförhållanden inom styrning
och ledning påverkar implementeringen av hållbar dagvattenhantering
(SSM – sustainable stormwater management). För detta genomfördes en systematisk
litteraturstudie och två kvalitativa fallstudier.

I litteraturstudien identifierades nitton utmaningar inom styrning och ledning som
hindrar implementering av SSM ur ett globalt perspektiv. Fallstudie 1 undersökte hur
styrningsfaktorer påverkar implementering av SSM ur ett lokalt perspektiv under två
distinkta styrningsstrukturer, nämligen hierarkiska i Kina och icke-hierarkiska i Sverige.
Styrningsfaktorer som visade sig påverka implementering av SSM kartlades i kausala
sambandsdiagram (CLDs – Causal Loop Diagrams) för att beskriva
beroendeförhållandena mellan styrningsfaktorerna. Fallstudie 2, som undersökte Sponge
Cities-initiativet i Kina, identifierande utmaningar för styrning och ledning som påverkar
en lokalt implementerad, men nationell, SSM-policy. Det konstaterades att konventionell
grå infrastruktur fortfarande spelar en viktig roll i Sponge Cities-initiativet på grund av
brist på utrymme, en allmän brist på kunskap om SSM samt på grund av att kvantifierbara
mål prioriteras inom den snäva tidsramen för genomförande.

Avhandlingen ger en översikt över utmaningar för styrning och beroendeförhållanden
mellan dessa som påverkar implementeringen av SSM. Dessutom presenteras ett visuellt
verktyg (SSM-CLD) för att hjälpa lokala myndigheter och icke-statliga intressenter att
förstå komplexiteten i SSM ur ett styrningsperspektiv.
