In this chapter, Michelle Bachelet emphasises that to be effective, development must embrace the goals of gender equality, social justice, peace and prosperity. She highlights the contribution that official development assistance (ODA) has made to empowering women and girls to exercise their rights fully, as equal citizens. Partnerships on gender equality between the United Nations (UN) and the Organisation for Economic Co-operation and Development (OECD) have also played a fundamental role in ensuring enhanced support to and impact on gender equality goals, particularly as the deadline for achieving the Millennium Development Goals (MDGs) approaches. Nonetheless, pervasive under-investment by donors, among other reasons, has led countries to lag behind on gender equality commitments. This chapter makes recommendations on how to remove the barriers that prevent women from realising their full potential, and enable the achievement of gender-equitable development results.
