Climate change exerts influence on the globe over relatively long temporal and at broad spatial scales. However, at the local scale in which communities undertake their daily activities, changes in land-use may result in changes that accumulate and manifest more quickly in the landscape. In this paper we set out a methodology for identifying social-ecological system (SES) vulnerabilities in the landscape with respect to freshwater resources for Arctic communities. A multiple-scale approach is used at regional and watershed scales and is demonstrated for the Seward Peninsula region, Alaska and the Fish River watershed on Seward Peninsula but may be applied elsewhere. The approach includes change in permafrost distribution as an important effect of climate change, and change in mining activity as an important land-use effect. Vulnerability in the SES is identified as a consequence of spatially coinciding values. The resulting patterns of vulnerability highlight the interaction between changes, which act on slower temporal scales (e.g., permafrost distribution) and changes which act more quickly (e.g., downstream aggregation of mining activity). These results are discussed in the context of using the integration approach outlined in this paper to better enable communities' responses to change at local scales in such a way that they are both adaptive and resilient.
