The climate is changing. In B.C. recent technical guidelines published by the Provincial government projected a sea level rise (SLR) of half a metre by the year 2050, one metre by 2100 and two metres by 2200.
Similar projections have been made by other Canadian provinces. Rising sea levels will cause coastal communities to become increasingly vulnerable to issues such as: coastal flooding and reduced drainage capacity; coastal erosion; changes to coastal habitats and wetlands (i.e. salt marshes); reduction in coastal sea ice; and more frequent and intense storms, storm surges and wave action.
How can coastal managers respond to this new challenge?
In order to deal with these issues, coastal communities will require resilience and adaptive capacity to ensure their long-term sustainability.
The B.C. Ministry of Environment commissioned the preparation of the Sea Level Rise Primer. The Primer is a resource for coastal management authorities to identify, evaluate and compare options for adapting to potential impacts and hazards on both the Pacific and Atlantic coasts.
The Primer identifies four strategies (Protect, Accommodate, Retreat, Avoid) and 21 adaptation tools.
