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.

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.

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?

 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.

China—the world’s fastest-growing economy with the largest population—leads the world in cement production, the critical ingredient that has built China’s mammoth cities, sprawling roads, and other infrastructure. China pours 60 percent of the world’s cement; the country’s production in 2011-2013 surpassed U.S. production for the entire 20th century. While it paved the way for Chinese growth, it came at a dangerous cost: 1.6 million Chinese citizens die each year from respiratory illnesses linked to small particulate matter emissions, of which 27 percent come from cement production.

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.

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.

Last year, four rivers were granted legal rights: the Whanganui in New Zealand, Rio Atrato in Colombia, and the Ganga and Yamuna rivers in India. These four cases present powerful examples of the increasing relevance of rights-centered environmental protection. Like corporations, which have legal rights in many jurisdictions, these rivers are rights-bearing entities whose rights can be enforced by local communities and individuals in court. But unlike corporations, these rights are not yet recognized in international treaties. Which raises the question: what are the implications of rights for nature for international environmental law?
