As the Atlantic hurricane season kicks off this month, some coastal communities in the United States and small-island nations in the Caribbean are still recovering from last year’s record-breaking damage. At the same time, the heavy rains pounding the East Coast this week are part of a long-term trend towards more severe heavy rainfall events that have led to deadly floods and threaten critical U.S. military bases. Even on sunny days, cities such as Norfolk and Manila contend with high tide or “nuisance” flooding—a phenomenon that has increased as much as nine-fold since the 1960s, according to NOAA.

In 1995, World Bank official Ismail Serageldin warned that “the wars of the next century will be fought over water—unless we change our approach to managing this precious and vital resource.” Since then, the world’s water resources have come under ever-greater strain. At the same time, institutional frameworks for managing water resources remain weak throughout most of the globe. Only about a quarter of the world’s international river basins have adequate governance arrangements to prevent and resolve conflicts. Does this mean that we can expect the 21^st century to be wracked by water wars?

“Alaska is a place in which climate change is already impacting us in very observable ways,” says Byron Mallott, the  Lieutenant Governor of Alaska, in a video interview with Wilson Center NOW.  “We have erosion from sea ice leaving the coast. We have patterns of weather change. We have, in the North Pacific Ocean, ocean water change [and] temperature changes taking place. We have ocean acidification moving further north. We have had impact on fisheries already—economic impact.”

Iraqi Kurdistan is blessed with abundant water resources, but these resources are under increasing stress. Changing demographics, dam building in neighboring countries, and drought have driven Kurdish hydropolitics to a critical juncture where two distinct water futures are possible—and both have implications for regional stability and for U.S. interests.

Put simply, “the damn thing melted,” Navy Secretary Richard Spencer explained in recent testimony, referring to Arctic ice melt as the trigger for the new U.S. Navy Arctic Strategy that is to be released this summer. What the Navy planned as a 16-year road map is in need of updates after only four years, in part due to receding polar ice caps, which are “opening new trade routes, exposing new resources, and redrawing continental maps,” but also in part due to the rise of China as an “Arctic stakeholder” and increasing important player in the region.

When Secretary of the Navy Richard Spencer told the media last week that “the damn thing melted,” he wasn’t talking about an ice cream cone. As the Arctic faces unprecedented levels of open water, Spencer and other naval leaders recently testified to Congress about the U.S. Navy’s strategy, which is changing as quickly as the Arctic itself. 

Plastics. From the devastating effects of plastic pollution on our oceans, to the news that plastic bottles likely pollute the drinking water they contain, plastic pollution—the theme of this year’s Earth Day—has been a highly visible issue, and we’ve seen some notable progress on fighting the plastic battle.  

Food has long been used by countries to wage both war and peace, and the post-war era of American food dominance is no exception. Bryan McDonald, a professor at Pennsylvania State University, traces the United States’ “Food For Peace” strategy in his recent book, Food Power: The Rise and Fall of the Postwar American Food System, arguing that “food was central to national security” during this period.
