This article presents the results of a doctoral thesis evaluating the potential of citizen journalism training and its promotion in the fight against violence. It is based on a case study: the Agência da Boa Notícia Guajuviras (ABNG), a project between the City of Canoas and Brazil's Ministry of Justice, implemented in Guajuviras, a neighborhood marked by poverty and violence. Young people and adolescents receive three hours of classes on communication and citizenship. The research uses qualitative techniques. The results focus on two aspects: the evolution of journalism learning among students and the progress in their socialization with violence prevention as the ultimate goal. The ABNG, established in 2010, aims to promote violence prevention among young people in Guajuviras through communication and citizenship workshops. It is part of the National Security and Citizenship Program (Pronasci) and has trained young people in communication, human rights, internet, and journalism. The project has been successful in improving the social integration of its participants and has received recognition for its efforts. The ABNG provides a multimedia platform for young people to produce and disseminate information, contributing to their empowerment and social inclusion. The project has also helped to change perceptions of the neighborhood, challenging negative stereotypes. The study highlights the effectiveness of citizen journalism in promoting social change and empowering marginalized youth. The ABNG has shown that young people can become effective communicators and journalists, contributing to the fight against violence and promoting social justice. The project has also demonstrated the importance of education in communication and citizenship in fostering critical thinking and social responsibility among young people. The ABNG is an example of how citizen journalism can be used to promote social change and empower marginalized communities.This article presents the results of a doctoral thesis evaluating the potential of citizen journalism training and its promotion in the fight against violence.
