In partnership with Save the Children, we have collaborated with their global and national teams in Indonesia, Mexico, China, and Vietnam to develop girl-led advocacy strategies aimed at addressing violence as a barrier to equality, leveraging play as a means of fostering agency, and strengthening government investment in and accountability to girl-led movements. These strategies combined in-depth advocacy with widespread outreach. By amplifying girls’ voices and leadership, this partnership seeks to ensure girls are empowered and actively included in global and local policy discussions about their rights.
