Nearly 6,000 health experts, women’s rights advocates, government and private sector stakeholders from around the world gathered this week in Copenhagen to talk about — in the words of Women Deliver CEO Katja Iverson — “not if, not why, but how” the global development community can deliver for women and girls.

Flash mobs, attention grabbing displays of activism and demonstrations of innovations such as the Path-designed NIFTY infant feeding cup took place throughout the week at the fourth Women Deliver conference, the largest gathering on girls’ and women’s health and rights in the past decade.

Twenty-one percent of attendees were youth, and 23 percent were men. Unsurprisingly, talks at the conference revolved around inclusion — of youth in general but also of men and boys in conversations about everything from gender based violence to contraceptive access.
