Jovem Design Lisboa (JDL) is a prevention programme, developed by the Lisbon Municipal Police under the IcARUS Project-Innovative Approaches to Urban Security, that uses a design framework to engage young people to find creative solutions to problems in their community. JDL aims to foster youth positive behaviour, self-esteem, confidence and civic participation, providing practical life skills, improving police-youth relationships and strengthening the feeling of belonging to their community. 

JDL is implemented during a period of twelve weeks, in which police mentors and youth workers help young people (JDL teams) in designing improvement solutions for their communities.
