“The act of caregiving has unique impacts on women, in terms of economic, emotional, and physical well-being,” said Dr. Belén Garijo, the CEO for healthcare and executive board member of Merck KGaA, Darmstadt, Germany, at a recent Wilson Center event.

Just outside Nampula, in northern Mozambique, a huge granite dome overlooks the city, 500 feet high and a half-mile across. All along its southern flank, hundreds of men work in small groups, whittling away at the rock face with sledgehammers and picks. Smoke rises before dawn until well after dusk, as they stoke fires to heat the granite and use crowbars to prize free tombstone-sized slabs. Day by day, the mountain is carted away by the wheelbarrow-full. It’s backbreaking work that yields barely enough to live. Yet these informal quarries are nevertheless among the region’s largest employers. Certainly, more people have found work here than with Kenmare Resources, the Irish company that has sunk more than US$1 billion into mining titanium deposits along the nearby coast.

In 2014, we met with some of the technical leads of a major Chinese river basin authority in Beijing and asked them whether they were more worried about pollution or climate change impacts. Both, the engineers replied. Pollution affects us every day, they said, but changes in the climate erode our ability to supply drinking and irrigation water, manage floods, and generate electricity.

China must address its environmental and climate change challenges, such as reducing water pollution and building resilience to droughts, floods, and long-term climate shifts. But existing sources of finance have not met the growing demand for environmental projects.

To further its goals to strengthen the global economy, China has already invested $300 billion of its pledged $1 trillion towards its Belt and Road Initiative—a massive infrastructure investment plan that spans 60 countries across Southeast Asia, Central Asia, Africa, South Asia, the Middle East, and Eastern Europe. China’s initiative will shift the world’s political, environmental, and economic landscape.

Just days before the 2016 Summer Olympics began in Rio de Janeiro, the Brazilian city faced an unsavory problem: how to handle its overwhelming sewage. Nearly half of Rio’s municipal wastewater flowed untreated into Guanabara Bay, where the waters were so polluted by sludge that direct contact was deemed a health hazard to Olympic athletes.

“Water security and management represent the cornerstone of global conflict prevention,” said President Danilo Türk, chair of the Global High-Level Panel on Water and Peace and former president of Slovenia, at a recent Wilson Center event on water and peace. “The only alternative to water is water, and therefore, the matter of water is a matter of survival,” said Sundeep Waslekar, president of Strategic Foresight Group.

The first U.S. city to host a docked bike-share system, Washington, D.C., is now home to a rapidly growing influx of dockless bikes, with five companies vying for the market. The docked system still accounts for 87 percent of the shared bikes in the United States, but the number of dockless bikes—which can be located by riders using an app and then left anywhere—is growing rapidly. The data from these location-enabled bikes provide a unique opportunity to measure the point-to-point transportation needs of millions of people in some of the world’s densest cities.
