Comparing adaptive capacity of Arctic communities responding to environmental change

Adaptive capacity (AC) is a widely used concept denoting assets or resources that people or a system can draw upon to cope with environmental change. When applied to a community, careful definition and measurement of AC is essential for identifying patterns and generating findings that may be useful for policy and transferable to other places. We identified and compared measures of 22 indicators for eight communities on Alaska's North Slope, based on consistency with theory, availability of data, and measurable community differences. Despite many cultural and institutional similarities, we found systematic differences among communities in each of the seven AC domains measured. Although every community had strengths in some domains, we could divide communities into three groups: high overall AC (one community), moderate overall AC (four communities), and low overall AC (three communities), based on average rank order across all domains. The comparative approach we developed can be helpful in identifying productive policy opportunities for strengthening community AC.
