Understanding the dynamic interplaying between urban violence and fragility and a countries' economic potential will be key to boosting development in most African countries. As a first step to tackle this challenge, a multi-country study undertook a comparative research process, which identifies common trends across Sub-Saharan Africa in order to facilitate the identification of mechanisms through which urban fragility and violence prevention could be further integrated into the development process of African countries. Research and pilot activities were undertaken in one country of each of the three sub-regions in the continent. In all the countries included, the analytical work focused on understanding dynamics of crime and violence in selected urban areas and existing institutional (formal and informal) responses to crime and violence, so as to further the World Bank understanding on how to best address urban fragility and foster local resilience while putting the building blocks to define an urban fragility agenda in the Sub-Saharan African region. This report gives an overview of this multi-country study.
