The study presented in this report is based on one month of field research in Port-au-Prince, from 19 August to 21 September 2012. It aims to define what the communitybased approach is in urban contexts. To do this, the research aims to clarify the notion of community in Haiti, and look at operational issues related to the community-based approach. The study therefore focuses on the different solidarity relations and community-based ties which exist in Haiti and makes a number of recommendations to improve the way this approach is applied in the field.
