Harnessing local authorities and community organisation’s knowledge and increasing their capacity to act in gang environments is the best way to address this rising issue.

It is widely recognized that street gangs are generally connected with violent and deviant behaviour. Aggressive youngsters are at greater risk of joining collectivities that we call street gangs or troublesome youth groups.

Nowadays, many countries have to deal with such groups, which may be called gangs, although researchers and policy makers often hesitate to call them this, because they compare their own groups to American stereotypes.

In this regard, we have the know-how and means to put forward a work plan to develop tools, materials and a training methodology that identify competences needed for engaging within local communities affected by gang activity, to harness their local knowledge and meaningfully increase their understanding and capacity to act in gang environments.
