Scenario-Based Planning for a Changing Climate in the Bras d’Or Ecosystem

This workshop report details a Participatory Scenario Development (PSD) process conducted in January 2010 to identify future development pathways and climate change adaptation strategies for the Bras d’Or ecosystem in Cape Breton, Nova Scotia. The process involved stakeholders developing three distinct scenarios for the year 2060—status quo, best case, and worst case—to analyze the synergies and trade-offs between regional development priorities and climate resilience.

• The workshop identified several current environmental and socioeconomic challenges in the region, including increasing storminess, declining fishery yields, a declining overall population with an increasing proportion of elderly and First Nations people, and limited public access to the coast, with 79 per cent of the foreshore in private ownership.
• Scenario 1 (status quo) assumes the continuation of current precipitation variability, limited integration of land-use policies, and a static or declining population. In this future, participants expect increased property ownership by foreigners and worsening environmental conditions, such as increased erosion and loss of habitat.
• Scenario 2 (best case) envisions a future by 2060 where the region is a UNESCO Man and the Biosphere (MAB) reserve with integrated land-use policies and increased economic activity. This scenario includes the emergence of Iona as a commercial hub and the implementation of provincially-owned buffer zones around the shores of the Bras d’Or estuary to aid climate adaptation.
• Scenario 3 (worst case) describes a future of rapid economic development—driven by mining, forestry, and coastal housing—without integrated land-use policies. This pathway is considered generally unsustainable, likely leading to increased pollution, loss of biodiversity, and high costs from increased insurance rates and infrastructure maintenance due to flooding.
• Projected climate impacts for the region include sea-level rise and storm surges causing flooding and increased salinity in the estuary and water table. Other risks include the destruction of shoreline infrastructure, loss of culturally significant areas such as Aboriginal burial sites, and the potential for increased forest fires as trees are weakened by disease.
• Participants identified critical adaptation options across three categories: infrastructure (e.g., shoreline retreat and vegetated buffer zones), governance (e.g., an integrated governance model for the Bras d’Or Lake watershed), and capacity building (e.g., sustainability education and visualizing climate impacts for developers).
• Short-term priority actions to reduce immediate vulnerability include eliminating building permits in areas prone to floods and landslides, following CEPI development guidelines, and increasing the number of stream gauges to monitor discharge and sediment movement.
• The report concludes that integrated land-use planning is the most essential requirement for increasing resilience across all scenarios, as it allows the region to account for the cumulative effects of diverse sectoral needs and coordinate adaptation actions effectively.
