The constraints facing women and girls worldwide range from epidemic levels of gender-based violence to biased laws and norms that prevent them from owning property, working, and making decisions about their own lives. The World Bank’s new book, “Voice and Agency: Empowering Women and Girls for Shared Prosperity,” documents major gender gaps and reviews promising policies and interventions. Underlining that women's agency–their ability to make decisions and act on them independently–has concrete as well as intrinsic value, WAPPP Fellow Jeni Klugman highlights new interventions from around the world that are used to empower women and girls, in conjunction with United Nations post-2015 global development agenda.
