Investing in women and girls is now frequently touted as a solution to global poverty and an engine of economic growth. According to McKinsey Global Institute’s Power of Parity report, achieving gender parity would add between $12 and $28 trillion to GDP by 2025. But in a complex world, where women are limited by unfair laws, unequal access to education and other resources, a greater burden of unpaid care work, and norms and attitudes which subordinate their role in society, what specific investments will create the transformative change in women’s lives needed to fuel global prosperity? And what roles should governments, the private sector, and women’s and other civil society organizations play in creating these changes? This panel looks at key strategies of women’s NGOs around the world, what the development world is doing to incorporate gender in its programs to end poverty and build resilient communities, how corporations and entrepreneurs are using a gender lens to create more sustainable business models, and the critical role that partnerships between these sectors play in creating lasting change.
