Social capital and healthy urbanization in a globalized world

This paper critically reviews the extent in which social capital can be a resource to promote health equity in urban contexts. It analyzes the concept of social capital and reviews evidence to link social capital to health outcomes and health equity, drawing on evidence from epidemiological studies and descriptive case studies from both developed and developing countries. The findings show that in certain environments social capital can be a key factor influencing health outcomes of technical interventions. Social capital can generate both the conditions necessary for mutual support and care and the mechanisms required for communities and groups to exert effective pressure to influence policy. The link between social capital and health is shown to operate through different pathways at different societal levels, but initiatives to strengthen social capital for health need to be part of a broader, holistic, social development process that also addresses upstream structural determinants of health. A clearer understanding is also needed of the complexity and dynamics of the social processes involved and their contribution to health equity and better health. The paper concludes with recommendations for policy and programming and identifies ten key elements needed to build social capital.
