This paper examines whether immigration can operate as a counter-process of depopulation and economic recession. Based on the comparative analysis of four case studies in Belluno (Italy), Klagenfurt-Villach (Austria), Dalarna (Sweden), and Haßberge (Germany), it analyses the key socio-economic factors explaining the successful integration of migrants, refugees, status holders and asylum seekers and examines under which conditions the arrival of newcomers can turn into a local development opportunity for these territories. The case studies feature four remote territories with the following common characteristics: they have undergone significant socio-economic transformations over the past decade, they face a population decline with an alarming outmigration of youth combined with an increasing ageing population, and central governments have channelled recent immigration and asylum seekers to peripheral areas to counterbalance negative demographic trends. Results show that integration paths undertaken by recipients differ significantly across the four territories. However, all case studies suggest that stable jobs and accommodations render remote and mountain localities attractive for refugees and status holders, who are usually more inclined to move to urban centres. Lastly, results from the case studies highlight the importance of designing individualised integration paths backed by social inclusion initiatives that can incite spontaneous collaborations and work relations with local inhabitants.
