MYSTIC Project Logo

Mystic Project

Young people with fewer opportunities from ‘left-behind communities’ are hard to reach and engage with. The solution to this circular and self-defeating problem is first, to bring the missing skills to youth workers and volunteers and, second, to support young people from left-behind communities to themselves become community leaders.
