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?

Solar farms—just like regular farms—cover large swaths of land, requiring between 3.5 to 16.5 acres per MW of generating capacity. The largest solar plant in the world, the 648 MW Kamuthi facility in Tamil Nadu, India, covers ten square kilometers. But it will be dwarfed by the 3,450 MW facility under construction on China’s Tibetan Plateau, which will span 298 square kilometers when completed. Building these large plants requires fundamentally changing how the land they sit on is used, which—without careful planning—could have negative impacts on the environment and local communities that could potentially lead to conflict. The backlash could not only derail solar projects, but could also fuel resistance to future renewable energy development.

Water engineer Gordon Mumbo of USAID’s Sustainable Water Partnership grew up in the small Kenyan village of Kamuga. Year after year, he watched as frequent floods from one of Kenya’s major rivers, the Nyando, disrupted village life. After 30 years of a wide-ranging career in water, for the first time since his childhood, he has returned to his birthplace, where he leads a team building community engagement in the Mara River basin.

 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.

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.

The idea of a “new middle” or “third way”—a blend of neo-liberal economic doctrines and social policies that was supposed to overcome the dichotomy between mixed economy and free market paradigms—more or less dominated U.S. and European politics for the last two decades. But today, this centrist consensus has been upended by a wave of populist, nationalist parties. Many have won over their electorates by questioning the benefits of free trade and globalization (as well as the international institutions that espouse them), while pursuing expansionary domestic economic policies.

The Columbia River basin—which spans four U.S. states, two Canadian provinces, and 32 Tribal Nations or First Nations—touches the lives of more than five million people each day. The basin’s 250 hydroelectric dams power everything from Google’s data center to irrigation pumps that spread water onto fields of alfalfa and potatoes. Steelhead trout and salmon rely on the river to spawn. Ships and tugboats transport millions of tons of cargo to and from the Pacific Ocean.
