The Central Arizona–Phoenix Long-Term Ecological Research (CAP LTER) Sustainable Future Scenarios project co-developed seven unique scenarios to address long-term challenges for the Central Arizona-Phoenix area and increase regional capacity to meet those challenges. The scenarios developed included one strategic scenario based on existing governance documents and institutional plans, three co-produced adaptive scenarios, and three co-produced transformative scenarios. The six co-produced scenarios were developed through participatory workshops held from December 2014 through January 2017; participants included stakeholders from a variety of area governing agencies, non-governmental organizations, and academic institutions. Synthetic outputs of the workshops include multi-criteria evaluations of the projected scenario outcomes, renderings, and narratives.
