Its name conjures an image of vivid deep blues. But when cobalt is dug out of the ground in ore form, there’s barely a hint of the rich hue it lends its name to. In the Democratic Republic of the Congo, which produces more than half of the world’s supply, it takes the form of heterogenite, a dull brownish mineral that could easily be mistaken for small clods of dirt.

But people die for this mineral. Children suffer for it. Livelihoods, educations, neighborhoods, environments and personal safety are sacrificed for it.

A special type of tree could facilitate peacebuilding in the Sahel. A stretch of semi-arid land south of the Sahara that runs from the Red Sea to the Atlantic Ocean through 10 countries (Eritrea, Sudan, Chad, Niger, Nigeria, Burkina Faso, Mali, Algeria, Mauritania, and Senegal). But the western subregion covering the Lake Chad area (the intersection of Chad, Cameroon, Nigeria, and Niger) and Liptako-Gourma (the tri-border zone of Burkina Faso, Mali, and Niger) in the Sahel has been the scene of a growing humanitarian crisis. Armed groups are terrorizing local populations. Rampant insecurity has forced 1 million people to flee their homes. People have been cut off from their livelihoods. Food insecurity is worsening. Casualties continue to mount. And climate change will likely exacerbate conditions, forcing more people to compete for depleted forest resources and land. More food shortages and instability will surely follow.

Usually after dinner, Mr. Ma would take off his shirt, shut the door, and begin work making plastic pellets from scrap. But tonight, he sits in his darkened yard staring at two SUV-sized plastic processing machines and a bundle of colorful scrap plastic. No lights are on, no machines grind, and no familiar theme song of CCTV-1 plays in the background. Walking through other villages in Wen’an County, more men meander around their yards filled with the same idle processing machines and mini-mountains of scrap plastic. Most have never studied English, but they are fluent in the language of plastics, sprinkling words like ABS, PP, and PVC into their conversations. They are the owners of small plastic scrap recycling workshops that were once booming—but are now silent.

The maternal and child health crisis in Washington, D.C. is “a public health crisis that has been hiding in plain sight for 30 years”, said D.C. Mayor Muriel Bowser at the second annual Maternal and Infant Health Summit on September 10 at the Walter E. Washington Convention Center. Panelists at this year’s summit discussed issues such as racial disparities in healthcare, proper nutrition and breastfeeding for new and expectant mothers, and support for midwives and doulas in D.C. “The health of a nation is dependent on the health of its women,” said actress and activist, Alyssa Milano.

This summer, United Nations agencies published three reports that offer a sobering assessment of the current state of international security and development, focusing on multidimensional poverty, hunger, and forcible displacement. As some countries succeed in steadily improving the living conditions of their most vulnerable populations, others have struggled to overcome sustained episodes of political instability and violent conflict. Together, the reports affirm the urgency with which the international community must reorient its policy priorities and take action to achieve the Sustainable Development Goals (SDGs) by 2030.

As researchers investigate the connection between climate change and conflict, the relative power of communities and individuals attempting to cope with climate change has become a recurring theme. While climate change may not directly cause conflict, it may be inextricably woven into pre-existing conflicts of power, ethnicity, and economic interest.

Fears of Central American caravans and Saharan smugglers keep European and U.S. leaders up at night. Desperate to manage migration, they turn to short-term fixes, which include blocking borders and supporting authoritarian leaders to contain people—their own citizens and others—before they get close to Europe or the United States. This bit of political theater appeals to some, but has limited effects in overall numbers. The long game consists of addressing root causes so people no longer feel compelled to move at all. But this too will do little to prevent migration north. If anything, it will encourage more people to move.

 This is what a water panic looks like in a major global city.

People hoard water. They queue for hours, well into the night, to fill jugs at natural springs. Like mad Christmas shoppers, they clear supermarkets of bottled water. They descend on stockers before they can fill the shelves.
