From global trends to local realities: A multi-scale scenario-building methodology for community infrastructure planning

This paper details a multi-scale scenario-building methodology designed to explore transport infrastructure futures in rapidly changing Circumpolar North communities, bridging global trends and national contexts with local realities. Focusing on Churchill, Canada, and Kirkenes, Norway, we employed a hybrid approach that combined top-down adaptation of existing global and regional socioeconomic scenarios with bottom-up, participatory ethnographic research to ensure local relevance and incorporate stakeholder knowledge. We developed coherent scenarios across global, regional (national), and local scales, allowing higher-level archetypes to manifest differently depending on locally specific features identified through fieldwork. This consecutive, nested process utilized morphological analysis and the Factor-Actor-Sector framework to maintain consistency while accommodating local specificities. The methodology centered not just on scenario creation but also on the function of scenarios as a tool for community dialogue, utilizing artistic visualizations in workshops to engage diverse stakeholders. This approach demonstrates a way to navigate the tension between global and national drivers versus local community needs, yielding distinct yet comparable local futures grounded in broader development pathways. It offers practical insights for deliberations and planning in uncertain environments, both built and unbuilt.
