Increasing societal integration and improving the quality of life are among the fundamental themes of urban sustainable development. In defining their vision of a Sustainable City , the municipality of Malmo, Sweden stresses the importance of having an integrated, multi-cultural society. However, as its large immigrant population continues to face issues of non-integration, Malmo still has many obstacles to overcome on its path to sustainability This research examines two facets of Social Capital -- bonding and bridging networks to explore the quality of social relations and ties within Afghan refugees in Malmo by conducting qualitative research focusing on Afghan students between ages of 15-20. While social capital can provide a bridge between immigrants and their inclusion in Swedish society, this research finds that the respondents rely on their high-levels of inter-connectivity among other groups of immigrants . This can act as a substitute for the lack of "bridging" social capital, not being utilized by the respondents, but has consequences for the sustainability of the city as a whole as it also reinforces the reliance on bonding social capital.
