Beth Schlachter, executive director of FP2020, discussed the London Summit on Family Planning that took place in July 2017, at which approximately $2.5 billion in new money was pledged for international family planning. We asked her to reflect on the unique FP2020 partnership, its achievements as well as the challenges it faces in meeting its goals in the world’s 69 lowest income countries. She stressed the importance of continued U.S. leadership in family planning, both in its bilateral assistance and in technical support at the country level, and her concerns about the global impact that would result if the U.S. abandons this role.
