Technological solutions, like improved equipment and logistical tools, have been trumpeted as keys to finally ending preventable maternal and child deaths. “But it’s not just technology innovation that we need; it is systems innovation,” says Dr. Harshad Sanghvi in this week’s podcast.

Leaders from around the world gathered in New York last month to discuss the replacements for the Millennium Development Goals, which expire next year. The topics included human rights, economic development, justice, disarmament, and terrorism, just to name a few. And that’s a problem, says Genevieve Maricle, policy adviser to the U.S. Ambassador at the U.S. Mission to the UN, in this week’s podcast.

When it comes to sustainable development, not all goals are created equal, says Wael Hmaidan, the director of Climate Action Network International, in this week’s podcast. Climate change “intersects everything we do,” he says, but is underrepresented in the Sustainable Development Goals (SDGs), a global development agenda being drafted to replace the Millennium Development Goals next year.

With less than 500 days until they expire, it’s almost certain that the Millennium Development Goals on child mortality and maternal health will be missed by many countries. Already, work on drafting the MDG successors has begun; but unless policymakers put nutrition at the center of maternal and child health systems, reducing global maternal and child mortality ratios by an appreciable amount will be difficult, says Dr. Ranu Dhillon in this week’s podcast.
