Working with men and boys is a particularly necessary and strategic area of work, a leading theme of the Secretary-General’s Campaign, and recognized as a long-overdue area of increased focus for accelerated progress on preventing gender-based violence. Programming by a joint inter-agency initiative Partners for Prevention Programme (with UNDP, UNIFEM and UNV) focuses on masculinities discipline, and forging stronger partnerships with pro-gender equality. The model seeks to advance transforming male attitudes and behaviors, including by learning from, adapting and evaluating select interventions that  have demonstrated results in attitudinal change.  At the policy level, there is also a need to incorporate and strengthen concrete measures related to male outreach and prevention in order to ensure comprehensive plans are adopted on ending violence against women.
