Sewage—refuse liquids or waste matter usually carried off by sewers—is at the front lines of a global movement for clean energy. Innovative U.S. cities are digging into their dirtiest depths to create new sources of power that optimize economic benefits, generate clean energy, and control pollution. This wastewater-to-power movement is just beginning to catch on in China. But with some of the largest and most densely populated cities in the world, the country could be poised to lead a sludge-to-energy revolution.

Since 1987, the number of women dying during pregnancy and delivery has dropped by 43 percent, saving hundreds of thousands of women’s lives—and changing the lives of their families—around the world. “Our achievement in making maternal mortality an injustice that needs to be recognized by health ministers, by heads of state, by heads of agencies, has been, I think, the single greatest achievement of the Safe Motherhood Initiative” since it began 30 years ago, said Ann Starrs, President and CEO of Guttmacher Institute, at a Wilson Center event marking the anniversary of this important effort.

The new year promises some big changes for the field of environmental security—and some big moves for the Environmental Change and Security Program (ECSP). As we say hello to 2018, we wave goodbye to Roger-Mark De Souza, and welcome him to our team of advisors and fellows. And I’m excited (if a bit daunted) to step into his shoes as our Acting Director and tackle the challenges to come.

This new year brings new projects—and some sad goodbyes. Today, I’m excited to begin my leadership of Sister Cities International, the world’s largest and oldest network of citizen diplomats. And I’m sorry to leave the Wilson Center, which has been my home for the last five years. But it’s not a long goodbye: I will continue to work with the Global Sustainability and Resilience team as a Global Fellow and as an advisor to the New Security Beat. In all of these roles, my New Year’s resolution is to renew our commitment to making a real difference in global well-being and sustainability. And while this year promises great changes, three key priorities will continue to inspire me and guide our collective efforts: resilience, complexity, and diplomacy.

The burden of care—the time, energy, and costs of caring for other people—is growing, and women shoulder the heaviest load. This burden can have negative consequences for businesses, too, as it affects the health and productivity of workers, as well as economic growth. At a recent Wilson Center Ground Truth Briefing, four leading experts discussed the ways in which progressive policies could help balance the burden of care to increase economic productivity and benefit both employers and employees.

If women have non-communicable diseases (NCDs)—like cancer and diabetes—“at the time of pregnancy, [it] can hugely impact future generations,” said Adya Misra the associate editor of PLOS One at a recent event hosted by the Maternal Health Task Force (MHTF) to mark the launch of the fifth MHTF-PLOS collection, Non-Communicable Diseases and Maternal Health Around the Globe. “If we do not address NCDs in a maternal health continuum of care, we will, for so many issues, be short changing the progress we have seen [in maternal health] because NCDs are on the rise,” said Katja Iversen, president and CEO of Women Deliver. 

Fisheries are a surprisingly common reason for conflict between countries. Between 1993 and 2010, 11 percent of militarized interstate disputes (MIDs) – conflicts short of war between two sovereign states – involved fisheries, fishers, or fishing vessels. While the conflicts often involve fresh fish, the implications for global peace and prosperity stink like fermented herring. As climate change threatens to change fish habitats, new governance strategies may be needed to prevent these “fishy MIDs” from sparking broader conflicts.
