Prevention of these crimes requires the interaction and participation of institutions in charge of fighting crime, such as municipalities and technical engineering organizations, in order to deny access and The realization of marginalization has a police force to identify criminals and finally adopt policies to attract public participation in crime prevention. One of these cases is the formal and informal control of people's participation, which is considered the most important strategy in preventive measures. Determining the understanding of the conceptual circle of participation and its relationship between decriminalization and environmental criminalization is an issue that has been investigated in this article with a descriptive analytical approach, and we are looking for an answer to the question, what are the strategies of public participation in crime prevention?
