This document summarizes an iterative scenario-building approach used to understand social and ecological vulnerability and adaptive capacity in rural communities. The researchers conducted comparative case studies in Montana and Colorado to examine vulnerability under different climate change scenarios. They developed initial scenarios with natural scientists and then collected social data through interviews and focus groups to integrate responses and capacities. The scenarios were iteratively refined and additional focus groups provided feedback. For the Big Hole Valley in Montana, scenarios addressed issues like drought impacts on ranchers and water availability. In Grand County, Colorado, recreation and land tenure diversity were noted, along with challenges to conceptualizing adaptation. Lessons indicated the approach engages stakeholders and inspires adaptation planning, but moving from discussions to action remains a challenge.
