The Kurdish people’s century-long quest for self-determination reveals a key aspect of ethnic separatist conflicts. Ideas of nationhood can endure for generations, unifying people across borders and often making separatist conflicts hard to resolve. But how much harder is it to resolve separatist conflicts than other violent, non-territorial intra-state wars (such as political revolutions)? In practical terms, how much longer, on average, can policymakers expect separatist conflicts to persist and reoccur than the typical political revolution? These are tough questions. Surprisingly, demography helps us find the answers.

The shift to a low-carbon economy is not only underway, it is accelerating. Last year, Costa Rica generated more than 99 percent of its electricity using renewable sources;  Germany expanded its onshore wind power capacity by 5,300 MW, and in the United States, more than 62 percent of new power plants under construction will produce renewable energy. What does this rapid increase mean for the countries that supply the inputs required to build these new facilities—particularly those countries that are struggling with fragility or corruption?

While most people killed in wars are male, several studies have found that “mortality among women in some high-intensity conflicts was as severe as male mortality,” said Henrik Urdal, the Director of the Peace Research Institute Oslo (PRIO), at a recent Wilson Center event on the links between maternal and child health, aid, and armed conflict. “Maternal health is a very natural place to start” when researching excess mortality and indirect deaths among women impacted by war, said Urdal.

Last month, Bolivia filed a counterclaim against Chile in the International Court of Justice—the latest salvo in their battle over rights to the waters of the Silala River. The court will decide whether Silala is “an international watercourse”—thus granting water rights to Chilean mining operations—or simply an artificial diversion of Bolivian spring water by Chile. This legal case marks the latest chapter in Bolivia and Chile’s historically delicate relationship, which dates back to the War of the Pacific in the late 19^th century.

“In the last decade, almost half of Africa’s elephants have been killed for their ivory, and some experts are predicting that both elephants and rhinoceros will be extinct by 2030,” said Nancy Lindborg, President of the U.S. Institute of Peace at a recent event on wildlife poaching and trafficking. The illegal trade in protected wildlife is worth US$7-10 billion—some of which has ended up in the pockets of armed groups like Al-Shabaab and the Lord’s Resistance Army, said Lindborg.

While dismayed Americans watched the “zero tolerance” policy of family separation unfolding at the Mexican border, across the Atlantic, another shocking migration crisis continues to fester. Behind the grueling headlines of drownings in the Mediterranean Sea, migrants run a gauntlet of abuse through the Sahara desert to reach the Libyan coast. Armed militias and terrorist organizations across the Sahel profit by smuggling people displaced by climate, population, and security crises. While European policymakers struggle to cope with arrivals, their containment approach consistently disregards the root causes that force people to take such unimaginable risks. The high value of these human commodities not only exposes vulnerable migrants to torture, extortion, and even enslavement, but also provides funds for terrorist groups intent on attacking the West.

Last month, a partially completed dam in Laos’ Attapeu province collapsed, washing away people and villages in its path. Hundreds of people are still missing and more than six thousand are homeless. And after last summer’s hurricanes, U.S. citizens in Houston and Puerto Rico escaped death but were forced to evacuate when dams were flooded. Dam failure can be catastrophic for people, property, and power—and the risks are rising, due to lack of investment in maintenance, growing vulnerability to climate change, and the demonstrated potential of cyberattacks.
