Hardly a day goes by without a news story on some violation of women's rights. In recent months, appalling incidents of violence against women and girls, from Delhi to Johannesburg to Cleveland, have sparked public outrage and demands to tackle these horrific abuses.

In Bangladesh and Cambodia, the shocking loss of garment factory workers' lives, many of them women, sparked global debate on how to secure safe and decent jobs in our globalized economy. In Europe, the disproportionate impact on women of austerity cuts and the use of quotas to get more women on corporate boards continue to make headlines.

Even though women have made real gains, we are constantly reminded how far we have to go to realize equality between men and women.

World leaders recognized the pervasiveness of discrimination and violence against women and girls when they signed onto the visionary Millennium Declaration in 2000. Amongst the eight Millennium Development Goals, they included a goal to promote gender equality and women's empowerment.

With these goals set to expire in 2015, we are now in a race to achieve them. We are also in the midst of a global conversation about what should replace them. It is time for women to move from the sidelines to the center.

In a new post-2015 development agenda, we must build on the achievements of the MDGs while avoiding their shortcomings. Everyone agrees that the goals have galvanized progress to reduce poverty and discrimination, and promote education, gender equality, health and safe drinking water and sanitation.

The goal on gender equality and women's empowerment tracked progress on school enrollment, women's share of paid work, and women's participation in parliament. It triggered global attention and action. It served to hold governments accountable, mobilize much-needed resources, and stimulate new laws, policies, programs and data.

But there are glaring omissions. Noticeably absent is any reference to ending violence against women and girls. Also missing are other fundamental issues, such as a woman's right to own property and the unequal division of household and care responsibilities.

By failing to address the structural causes of discrimination and violence against women and girls, progress toward equality has been stalled. Of all the MDGs, the least progress has been made on the fifth MDG, reducing maternal mortality. The fact that this has been the hardest goal to reach testifies to the depth and scope of gender inequality.
