In  recent  years  the  importance of  Community-Based Crime  Prevention  Projects  (CBCP)  has  been pointed out  in  literature. However there are few studies which systematically analyze their main features, outputs and outcomes.  This  study,  on  the  one  hand , aims  to  provide  a  better understanding about this type of interventions for crime prevention, analyzing the specific contexts in which they emerged in Latin America and Africa. On the other hand it aims to analyze the type of community participation within the framework of the CBCP experiences and more importantly, we seek to explore if the type of community participation has an effect on the outcomes of these experiences in Latin America and Africa.
