Abstract

Adaptation options in response to climate impact scenarios for marine mammals and seabirds were developed based on the IPCC vulnerability framework. Under this framework, vulnerability to the physical effects of climate change can be reduced by adaptation options that reduce exposure of individuals, reduce the sensitivity of individuals, and increase the adaptive capacity of individual/species to cope with climate change. We evaluated options in each vulnerability category with three screening tools collectively forming an approach we term sequential adaptation prioritization for species. These tools were designed to evaluate (i) technical aspects (cost-benefit-risk, CBR), (ii) institutional barriers, and (iii) potential social acceptability. The CBR tool identified which adaptation options were high cost and low benefit, might be discarded, and which were high benefit and low cost, might be rapidly implemented (depending on risk). Low cost and low benefit options might not be pursued, while those that are high cost, but high benefit deserve further attention. Even with technical merit, adaptation options can fail because of institutional problems with implementation. The second evaluation tool, based on the conceptual framework on barriers to effective climate adaptation, identifies where barriers may exist, and leads to strategies for overcoming them. Finally, adaptation options may not be acceptable to society at large, or resisted by vocal opponents or groups. The social acceptability tool identifies potentially contested options, which may be useful to managers charged with implementing adaptation options. Social acceptability, as scored by experts, differed from acceptability scored by the public, indicating the need to involve the public in assessing this aspect. Scores from each tool for each scenario can be combined to rank the suite of adaptation options. This approach provides useful tools to assist conservation managers in selecting from a wide range of adaptation strategies; the methodology is also applicable to other conservation sectors.
