Mining Towns in TransitionArctic Legacies judit malmgren, dag avango, curt persson, annika e. nilsson, thierry rodonTowns built around mining operations in the Arctic tend to be vulnerable during deindustrialization as most jobs are in a single industry. This one-sided labor market, along with substantial distances to other employers or business opportunities entails very limited access to alternative sources of income. Therefore, when a crisis hits, the challenges of sustaining former mining towns are particularly severe. Another challenge is the legacy of the mining past that the companies leave behind.In this chapter, we use a broad definition of the concept of legacies: It will signify anything handed down from the past, material and immaterial. To define what mining legacies may consist of, we will apply a socio-technical systems perspective, incorporating all social and physical components needed for mining (Hansson, 1998;Avango et al., 2019). Thus, material legacies of mining are artefacts and structures constructed and used in mining systems, such as mines and processing plants, infrastructure for transport and energy, waste and morphologically transformed landscapes, as well as built environments for housing, services, and sociocultural activities such as sports, entertainment, culture, and religious practice. Immaterial legacies of mining can be entities such as skills, identities, and memories.Research on the role of such legacies in post-industrial transitions has shown that they can be used for supporting the sustainability of industrial settlements beyond the end of the industries supporting them (Isacson, 2013;Orre, 2016;Kempinsky, 2017). This can take different forms. One is by re-using and repurposing material legacies, for example, running a workshop in a former generator building or using a mining road as a tourist trail. Another is by heritagization, which we here define as a process in which actors define and ascribe particular and exclusive historical values to selected legacies and protect them for posterity (Harrison, 2013). Heritagization can generate new economic values but also other values, such as quality of living. Can legacies from the past also help Arctic mining towns in transition to survive? 229
