Transcript Glenn Davis ACASA - Atlantic Climate Adaptation Solutions

Atlantic Climate Adaptation Solutions
(ACAS)
An initiative of the Atlantic provinces and the
Government of Canada
Regional Adaptation Collaborative
The concept of the RAC arose from the findings of From Impacts
to Adaptation: Canada in a Changing Climate
(www.nrcan.gc.ca/earth-sciences/climate-change/communityadaptation/assessments/132)
The program recognized the need for a regional approach to
adaptation and to build on the foundation of local knowledge
and expertise in government and non-government decisionmakers and practitioners across the country
Regional Adaptation Collaborative
The Atlantic provinces collaborated on adaptation projects with a
principal focus of impacts that occur at the interface of land and
sea. The objective of the program was to provide individuals and
communities with a better understanding of their vulnerabilities
to the effects of extreme weather events and long-term climate
change and take ownership of the risks by developing policies
and plans that reduce the negative economic and social costs of
climate change.

Projects have:
•
•
helped assess climate risk and vulnerability
advanced adaptation decision-making through the development of regionally
relevant tools, knowledge, networks and policies

Coastal Land Use Risk and Vulnerability
Coastal Erosion Assessment - Prince Edward Island
• erosion will increase with
more intense and frequent
storms
• $4 Billion worth of property
at risk
RESULTS:
• historical erosion rates
updated
• future rates will likely be 1.5
- 2 times
• coastal development
policies are inadequate
Alberton, PEI
Inland Land Use Risk and Vulnerability
Grand Falls, NB Slope Stability and Erosion Assessment
• Bank failure and erosion
threatens numerous properties
and significant infrastructure
• Impacts from heavy rain events
and river flooding expected to
increase
RESULTS:
• Risk assessment and mapping
completed and recommendations
made for improved stormwater
management, bank stabilisation
and future development planning
Infrastructure Risk and Vulnerability
Chignecto Isthmus, Nova Scotia and New Brunswick
• Much critical infrastructure not built to withstand future climate
conditions.
• Vulnerable to sea level rise and
storm surges, e.g. dykes, road and
rail in Chignecto Isthmus
RESULTS:
• Assessments of infrastructure
vulnerability to:
• Sea Level Rise + 1 metre ?
• Storm surges + 2 metres ?
NEXT STEPS:
• Recommendations for
infrastructure / transportation
adaptations - design and
placement.
Why did we collaborate?
• Adaptation focus is relatively new and climate science is
technical and multi-dimensional
• Common issues, conditions and objectives
• Action needed is costly, complex and long-term
• Involves multiple stakeholders
– Outcomes are improved by involving multiple skill sets and
jurisdictions
– Implementation often involves multiple areas of authority
– No one group has all the expertise
• Achieve better results than could be accomplished
independently
The Future of Climate Adaptation
• The job hasn’t been completed
• There is information/tools out there
• There are knowledgeable people available –
researchers, local/provincial government
• There is value in working with neighbouring
communities or associations
