Summary: In situations where the future state of fisheries or ecosystems is difficult to predict through assessment models, the performance of management processes/policies and the speed with which changes can be measured and responded to, takes priority. Thus co-management approaches where operators are immediately reporting back the state of fisheries, habitats and general observations/trends is critical. These bottom-up processes must also feedback rapidly through to regional managers who will need to assess implications for broader ecosystem and cross-fishery impacts.
In applying the framework to the South East we identified firstly that the region is undergoing a Regime Shift Scenario. This assessment is supported by early anecdotal information since 1994 of species range shifts, further reinforced by the collective findings of researchers reported at a 2005 CSIRO workshop of oceanographic and ecological shifts, and more recent sightings, such as those reported from RedMap of species extending their nominal ranges.
The key findings for the South East are reported under the two phases of the study: (1) The vulnerability assessment of bioregions and species to determine projections of future impacts from climate change - using the Business As Usual scenario as a baseline, and (2) The adaptation assessment framework based on scenarios of climate change to identify regional and sector specific adaptations and linkages.
1. To develop a integrating climate change adaptation assessment framework for fisheries and aquaculture, suitable for use regionally and at a national level.
2. To test and apply this framework in the south eastern region to evaulate adaptation response options for stakeholders (managers, fishers, aquaculturalists)
3. To assess the application of the framework to apply to other regions around Australia.
