A dynamic Speakers' Corner at the Humanitarian Village saw Donal Forde, Secretary General of Irish Red Cross, outline a program which has transformed health and culture in Irish prisons.
It began four years ago as a community-based peer-to-peer approach, where prisoners are trained to deliver health, hygiene and first aid messages. It proved highly successful in reaching a traditionally-hard-to-reach group and has broadened to take in fitness, quitting smoking, HIV and other health testing.
The most outstanding result is around violence, where there's been a 50% drop in assaults on prisoners, and a 90% drop on assaults with weapons.
Mr Forde said the whole culture within prisons has transformed. Inmates now are more concerned about each other, and there's a collective effort to build a better community.
