Urban community gardens’ capability to yield aspects of social sustainability has been addressed in previous research. Nevertheless, further studies within this scientific field are requested for, exploring various socio-economic contexts and how such variables impact the outcomes of urban community garden initiatives. By the means of qualitative content analysis of material obtained via interviews and documents focusing on two urban community gardens in Skäggetorp, Linköping, on which a conceptual framework of social sustainability is applied,this study aims to investigate and seek a greater understanding of the potential and challenges of utilising urban community gardens as a planning strategy to foster social sustainability in socio-economic vulnerable neighbourhoods. The study finds that urban community gardens can bring various aspects of social sustainability, which can help meet the needs of socio-economic vulnerable neighbourhoodsin the strive for social sustainability. Many of these aspects are primarily created through the interaction occurring in the gardens. The study further confirms that urban community gardenscan function as educational hubs, allowing residents to practise language skills and learn about societal functions. Additionally, findings indicate that urban community gardens can be of financial significance in socio-economic vulnerable areas, a finding that previously mainly has been identified in studies of developing countries. Moreover, the study finds that urban community gardens allow existing traces of social sustainability to become visible and practised. However, low participation and lacking governmental support can obstruct the utilisation of urban community gardens as a planning strategy to foster social sustainability in socio-economic vulnerable neighbourhoods.
