The aim of this thesis is to explore a case of street and market vendors in urban Africa, who are members of a local network with transnational connections. The local network collaborates with a global network and a local policy institute with the purpose to strengthen capacity of street and market vendors. The thesis asks questions of membership experiences, processes behind agendas and implementation of capacity building for the vendors and perspectives on these capacity building efforts. Theories depart from contemporary globalization and focus on issues of transnational civil society networks and injustice. Specific theoretical contributions are drawn from Routledge and Cumbers (2009) global justice network-theory and Amartya Sen’s (2009) idea of justice. A qualitative case study was conducted in Accra, Ghana based on participatory observations and semi-structured interviews with street and market vendors and officials of both the collaborating network and policy institute. Membership experiences were understood to include capacity building effects and further concerned issues of knowledge, community and identity. Global and local factors combined and influenced the agenda and implementation of capacity building. Theoretical contributions were combined and useful in analysing the empirical case, and ethical considerations were fundamental to the research process.
