Shrinkage is a relevant phenomenon for many cities and this trend is predicted to continue in the future. Although urban shrinkage is well recognized in academic discourse, little research has been undertaken on its social aspects. This paper explores the concept of social capital in the context of urban shrinkage and elaborates on how it contributes to social sustainability in shrinking cities. After defining the concepts, we identify resources, empowerment, and participation as key indicators of social capital in the context of urban shrinkage. The paper analyzes these indicators in the shrinking, old industrial city of Heerlen, the Netherlands, based on 24 in-depth interviews with citizens, policy-makers, and entrepreneurs, as well as secondary data. The findings reveal the prominence of three interrelated issues: the importance of local culture, subjective experiences of shrinkage, and a lack of trust between citizens and politicians. We conclude that social capital can facilitate social sustainability in the context of urban shrinkage. However, trust and empowerment are not guaranteed in a shrinking context. In shrinking cities more investments should be made to foster cooperation between civil society and politics and the development of mutual trust.

In light of the ongoing urban shrinkage debate, planners stressed the need for new planning concepts and strategies. In this respect, the relevance of involving civil society in governance of urban shrinkage has been emphasized. So far, however these issues have received limited attention. This paper aims to contribute to the debate by investigating (1) how actors in civil society experience urban shrinkage and (2) their perspectives on the governance of urban shrinkage. We study this in two shrinking medium-sized cities: Heerlen (the Netherlands) and Blaenau Gwent (Wales). To answer these research questions, we make use of the concept of social capital. We follow a comparative case study design, primarily basing the analysis on data from 52 in-depth interviews. In the case studies, specific patterns of social capital can be observed: strong place attachment, strong informal participation and weak trust of civil society in local governments. However, the experience of urban shrinkage and the reaction to shrinkage differs. We conclude that understanding shrinkage and addressing it are predominately context related. Explanations based on historical developments and welfare state provisions are offered. The paper ends with reflections on the implications of these findings for governance of urban shrinkage.

In current research, the social return to citizens initiatives is important but often under-evaluated. Within this work, we collected the information that has emerged from measuring the social value of regenerative projects in shrinking cities. We used a case study of the regenerative project Gebrookerbos, a socio-spatial regeneration project in the shrinking city of Heerlen, the Netherlands. To assess the project’s monetary and immaterial aspects, a social cost–benefit analysis (SCBA) was used to understand the complexities of the costs and benefits associated with citizens in regeneration projects in a shrinking area. Drawing from the literature on urban shrinkage, citizen involvement, and social cost–benefit analyses, a theoretical framework was proposed. The case study included primary (i.e., interviews) and secondary (i.e., document analysis) data to identify the social value of the Gebrookerbos project, with results suggesting that the project has been meaningful to diverse stakeholders. Based on experiences with the SCBA of Gebrookerbos, one finding was the complexity of measuring citizens’ initiatives in terms of social return due to their process, organisation, and goals, in combination with the dynamics of shrinking cities. We discuss why research on social return to citizens’ initiatives is important and with this study we draw attention to the tendencies, opportunities, and future potential of citizens’ initiatives, which contribute to vacant open spaces and quality of life in shrinking cities.

The relevance of citizen participation in regeneration projects, particularly in shrinking cities, is widely acknowledged, and this topic has received a great deal of policy and academic attention. Although the many advantages of citizen participation in regeneration projects have been identified, its current forms have also received considerable criticism. In short, this criticism boils down to the conclusion that the ideal of citizen participation is not put into practice. This paper considers why this is the case, asking whether current participatory practices enable citizens to exercise influence as political actors in urban regeneration projects. In this paper, we examine this question based on Mouffe’s conception of the political, coupled with findings from our empirical research conducted in Heerlen North, The Netherlands. We conducted qualitative research on urban regeneration in the shrinking old industrial city of Heerlen. The findings reveal two distinct perspectives on citizen participation. Professionals see the existing context of citizen participation as a reasonable and practical but, in some respects, insufficient practice. Citizens’ views on participation are organized around feelings of anger, shame, and fear and are grounded in experiences of a lack of recognition. These experiences limit citizens’ abilities to exert true influence on regeneration projects. We conclude that efforts to regenerate shrinking cities should strive to recognize these experiences so as to create conditions that generate respect and esteem and, as such, enable urban social justice.

This article explores social capital in the shrinking old industrial area of Blaenau Gwent, Wales. The results indicate that economic change has impacted the social capital in unfavourable ways, leading to mistrust, a negative image of the area, low empowerment and low participation. Tradition appears to have played a strong role in disabling the transformation of the area, but new paths for social development are emerging slowly. Changes in social capital can be observed through the actions of entrepreneurs. Finally, trust between actors and flexibility in handling available resources are identified as key requirements for social transformation. Graphical Abstract
