Climate change impacts and adaptation of commercial marine fisheries in Australia: a review of the science
Quantitative foresighting as a means of improving anticipatory scientific capacity and strategic planning
Decisions about the future are necessarily uncertain, and increasing social-political change and technological disruption compound this uncertainty. Despite this, scientists and scientific organizations must still plan for the future. Foresighting is one approach used to inform thinking about future conditions. We describe a quantitative foresighting approach for a range of general science and marine-specific foresights. Repeat assessment over a 2-year period showed that the time-specific likelihood futures were consistent between years. Our approach can be used to prepare scientists and their institutions for possible futures, and to prioritize among these choices
Adaptation options for marine industries and coastal communities using community structure and dynamics
Identifying effective adaptation strategies for coastal communities dependent on marine resources and impacted by climate change can be difficult due to the dynamic nature of marine ecosystems. The task is more difficult if current and predicted shifts in social and economic trends are considered. Information about social and economic change is often limited to qualitative data. A combination of qualitative and quantitative models provide the flexibility to allow the assessment of current and future ecological and socio-economic risks and can provide information on alternative adaptations. Here, we demonstrate how stakeholder input, qualitative models and Bayesian belief networks (BBNs) can provide semi-quantitative predictions, including uncertainty levels, for the assessment of climate and non-climate-driven change in a case study community. Issues are identified, including the need to increase the capacity of the community to cope with change. Adaptation strategies are identified that alter positive feedback cycles contributing to a continued decline in population, local employment and retail spending. For instance, the diversification of employment opportunities and the attraction of new residents of different ages would be beneficial in preventing further population decline. Some impacts of climate change can be combated through recreational bag or size limits and monitoring of popular range-shifted species that are currently unmanaged, to reduce the potential for excessive removal. Our results also demonstrate that combining BBNs and qualitative models can assist with the effective communication of information between stakeholders and researchers. Furthermore, the combination of techniques provides a dynamic, learning-based, semi-quantitative approach for the assessment of climate and socio-economic impacts and the identification of potential adaptation strategies
