1 Network Approaches to Managing Complex Urban River Systems Research Team: CSIRO Sustainable Ecosystems CSIRO Land and Water Complex Systems Science University of Melbourne In collaboration with: Swan River Trust

2 Regional Setting  Swan region covers 7000 km 2  In addition to the Swan and Canning, 6 additional sub-catchments and estuaries  75% nutrients  Dominant surface feature is the Swan –Canning Estuary (55 km 2)  Avon River Basin (121,000 km 2 )  75% salt load; 25% nutrients into Swan/Canning

3 Socio-cultural landscape  1.25 million people (70% state population) growing at 1.2% pa  Indigenous presence for over 40,000 years  high demands on land & water resources for Industry Industry Commerce Commerce Residential Residential Transport Transport Lifestyle needs Lifestyle needs  Estuarine system has important environmental values  Significant economic and recreational asset

4 NRM Goals for the region  Conserve natural diversity  Ensure acceptable water quantity and quality  Improve land condition  Improve management processes Legislation Legislation statutory processes statutory processes programs and strategies programs and strategies to be integrated to improve natural resource management  Achieve cultural change Government Government industry and industry and Commerce Commerce Community Community individual behaviours individual behaviours For better understanding and management of the Region’s natural resources

5 Strategic initiatives  Swan and Canning River Precinct Planning Project  Swan Canning Environmental Protection Plan (SCEPP)  Riverplan: a comprehensive management plan and implementation strategy for SCEPP

6 Swan River System  Institutional setting complex governance arrangements complex governance arrangements jurisdictional overlap in responsibilities jurisdictional overlap in responsibilities interactive processes that are unclear or difficult to resolve interactive processes that are unclear or difficult to resolve  Multiple stakeholders Large number of players / nodes Large number of players / nodes  Emerging features

7 Central questions  Can network theory and associated social analysis be used to solve real world, complex NRM problems  Can knowledge about the functionality of the Swan River network be used in planning and for the implementation of the Swan-Canning EPP by Swan River Trust

9 The Riverplan network – what does it show? The Riverplan network – what does it show?  High interconnectivity of system  Complexity  Identification of both highly connected and peripheral agency roles in Riverplan  A very complicated system!

10 The Riverplan network Due to high level of complexity  Focus on a specific Swan River management issue: development and river amenity  Conversion of Riverplan network into formal models and preliminary analysis  Semi-structured interview questions developed and tested - to provide network information for this issue set  Data collection from core ‘Riverplan’ agencies

11 Development and River Amenity

12 Prisoner’s Dilemma  Tension between interest groups along the Swan River

13 The Executive Inter- Organization Network

14 Organisational links of any responsibility Red=respondent; Yellow=non-respondent

15 Organisational links of any responsibility Red=respondent; Yellow=non-respondent

16 All Crucial Ties Red=respondent; Yellow=non-respondent

17 Crucial Ties: “Implementing Policy” Red=respondent; Yellow=non-respondent

18 Crucial Ties: “Legislative Initiatives”

19 Red=respondent; Yellow=non-respondent Crucial Ties: “Developing Policy”

20 Red=respondent; Yellow=non-respondent Very Important but Difficult Ties

21 Red=respondent; Yellow=non-respondent Very Important but Difficult Ties: “Implementing Policy”

22 Red=respondent; Yellow=non-respondent Very Important but Difficult Ties: “Legislative Initiatives”

23 Red=respondent; Yellow=non-respondent Very Important but Difficult Ties: “Developing Policy”

24 Lattice Models. 155 multiplex ties, each involving up to 14 areas of responsibility Lattice representation of array for 155 ties  14 areas In the lattice: Node size indicates no. of edges with fitted profile Node size indicates no. of edges with fitted profile A node corresponding to one or more multiplex ties is at or above all of the areas in its (fitted) profile A node corresponding to one or more multiplex ties is at or above all of the areas in its (fitted) profile An area is at or below all multiplex ties which include it in their (fitted) profiles An area is at or below all multiplex ties which include it in their (fitted) profiles One area is below another if responsibility for the first entails responsibility for the second in the set of fitted profiles One area is below another if responsibility for the first entails responsibility for the second in the set of fitted profiles
