Atlantic Climate Adaptation Solutions Project
The Atlantic Climate Adaptation Solutions Association (ACASA) is a nonprofit organization formed to coordinate project management and planning
for climate change adaptation initiatives in Atlantic Canada.
ACASA is supported through the Regional Adaptation Collaborative
(RAC), a joint undertaking between the Atlantic provinces, Natural
Resources Canada and regional municipalities and other partners.
As a requirement for the 2010 – 2015 Gas Tax Agreement, municipalities
will be required to prepare and submit to Service Nova Scotia and
Municipal Relations a Municipal Climate Change Action Plan (MCCAP).
The MCCAP will focus on climate change adaptation, and will describe
how municipalities plan to respond to impacts associated with climate
change.
Nova Scotia ACAS Sites
In Nova Scotia there are six (6) ACAS sites:
Tantramar/ Amherst
Oxford
Minas Basin
Halifax
Lunenburg
Yarmouth
In Yarmouth the ACAS project focused upon
storm surge and sea-level rise implications.

Central Nova, Dec. 2010 – 13 million
Southwest Nova, Nov. 2010 – 5.6 million
Step-by-Step Planning Framework
Step One: Build a Team
Step Two: Identify Impacts
Step Three: Affected Locations
Step Four: Affected Facilities & Infrastructure
Step Five (a): Social Implications
Step Five (b): Economic Implications
Step Six: Environmental Impacts
Step Seven: Priorities for Action
Purpose of this planning exercise:
Start the process of understanding how climate
change will impact and affect Nova Scotia’s
municipalities.
Summary of MCCAP Process
