The present project aims to further develop methodological and theoretical concepts of visual anthropology, applying them to the fields of youth marginality and youth delinquency, in three different countries of the lusophone space (Portugal, Brazil, Mozambique). It aims to “attack” the (theoretical, empirical and practical) issues of youth marginality and youth delinquency by means of an audio-visual research strategy from a “shared”, collaborative anthropological perspective, making, at the same time, a strong contribution to the state of knowledge of youth studies, legal anthropology and criminology. Within the project´s 6 years timeframe, youth from marginalized urban communities in three different cities will be engaged in participatory artistic undertakings, placing special emphasis on the importance of “images”, in the broadest sense, for the process of construction of personal and group identity/alterity. The comparative research strategy seeks to foster a better scientific understanding of the dynamics of youth marginality, taking into account the diverging ways the respective nation states have conceptualized, and reacted to, the problem of youth exclusion and youth delinquency.
