The challenge of peacebuilding missions is not only to stop violence and prevent a rekindling of conflict, but also to help societies and governments reset their internal relations on a peaceful path towards sustaining peace.

The security implications of climate change emerged as an important area of concern in the mid 2000s in both policy circles and academia. Since then, there has been much research exploring causal pathways between climate phenomena and violent conflict, often with inconclusive or mixed results.

Great power competition in Asia is not only about control of critical waterways in the South China Sea, but also about who controls Asia’s fresh water. The future of Asia’s water—upon which about four billion people depend—lies in China’s hands. Through its presence in Tibet, China controls the headwaters of ten of the eleven major rivers of Asia. So far, China has taken a relatively cooperative approach to sharing water with its neighbors as part of the systematic consolidation of its “soft power” over downstream countries. But climate change and rapid growth are threatening to upset this delicate diplomatic balance. What happens when China’s own thirst outpaces its resources? And how will China’s choices affect U.S. interests in the strategic Asia-Pacific region?

The two poles of our planet—the Arctic and Antarctica—demand greater attention right now. For decades, the United States has played a leadership role in both regions, a responsibility that it must continue to fulfill as a warming climate and other drivers of change are creating new challenges and opportunities. Regrettably, the Trump Administration has not devoted the resources or high-level attention necessary to maintaining American leadership position on these critical matters.

 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.

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.

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.
