Pathways for Coastal Adaptation in Metro Vancouver, Alexandra Heather RUTLEDGE

  1. Pathways for Coastal Adaptation in Metro Vancouver Alexandra Rutledge University of Waterloo IDRC DAVOS 2016
  2. Outline  Introduction  Background  Research Question  Research Methods  Initial Findings  Summary  References  Acknowledgments
  3. Study site: Metro Vancouver Purpose: to identify the barriers that underpin the uptake of managed retreat as a coastal adaptation method to sea level rise and coastal flooding in Metro Vancouver Source: Adaptation Options:  Protect  Accommodate  Avoid  Retreat Metro Vancouver Municipalities
  4. Managed Retreat Managed retreat is an adaptation strategy whereby a planned decision is made to relocate people or infrastructure in the anticipation of a coastal hazard (Turbott & Stewart, 2006) Managed Retreat
  5. Coastal British Columbia Source: Ausenco Sandwell. (2011). Draft policy discussion paper . Provincial Flood Construction Level recommendations: – ~0.5m by 2050 – ~1.0m by 2100 – ~2.0m by 2200
  6. Flood Management challenges  2003 Local Government Act  4% of dike segments meet current provincial standard  71% of dikes are vulnerable to failure by Source: Delcan. (2012).
  7. Research question What are the barriers to managed retreat as a coastal adaptation strategy in Metro Vancouver?
  8. Methodology  Qualitative research strategy ◦ Literature review ◦ Semi-structured key informant interviews  25 total interviews  Actors: engineers, planners, academics, politicians, sustainability managers Seawall Stanley Park Dike maintenance in Delta
  9. Key Informant Interview Hierarchy
  10. Initial Findings
  11. Barriers to Managed Retreat in Metro Vancouver  High-value land  Political will  Funding  Loss of sense of place  No Canadian examples of retreat  Complexity of implementation  Education of public & politicians  Time & uncertainty  Jurisdictional authority  Lack of existing policy Port of Vancouver Crescent Beach community
  12. Summary  Managed retreat has not gone beyond a desk-top conversation  Short-term economic conditions and perceived social hardship are strong barriers  Managed retreat needs long term commitment and political and public support  Legacy of historic reliance on dikes continues  Support needed from higher levels of
