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/community-adaptation/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 decision-makers 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.
Under these Tasks/subtasks25 projects across the Atlantic provinces50 communities of a variety of sizes involved100 non-profit and for profit partners

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

• erosion will increase with more intense and frequent storms
• $4 Billion worth of property at risk
• historical erosion rates updated
• future rates will likely be 1.5 - 2 times
• coastal development policies are inadequate
Coastal Land Use Risk and VulnerabilityCoastal Erosion Assessment - Prince Edward Island
RESULTS:
Alberton, PEI
• Bank failure and erosion threatens numerous properties and significant infrastructure
• Impacts from heavy rain events and river flooding expected to increase
• Risk assessment and mapping completed and recommendations made for improved stormwater management, bank stabilisation and future development planning
Inland Land Use Risk and VulnerabilityGrand Falls, NB Slope Stability and Erosion Assessment
RESULTS:
Infrastructure Risk and Vulnerability
• Much critical infrastructure not built to withstand future climate conditions.
Chignecto Isthmus, Nova Scotia and New Brunswick
• Vulnerable to sea level rise and storm surges, e.g. dykes, road and rail in Chignecto Isthmus
• Assessments of infrastructure vulnerability to:
• Sea Level Rise + 1 metre ?• Storm surges + 2 metres ?
• Recommendations for infrastructure / transportation adaptations - design and placement.
RESULTS:
NEXT STEPS:
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
