Every year, millions of shorebirds migrate to the Arctic to breed—some coming from as far away as Australia and New Zealand—and then head back again. Nearly all of the birds making this journey spend time in the food-rich intertidal mudflats of the Yellow Sea ecoregion, on the east coast of China and the west coasts of the Korean peninsula. But as China’s economy has grown, around 70 percent of the intertidal mudflats in the Yellow Sea area have disappeared—the land drained and “reclaimed” for development. All of the more than 30 species of shorebirds that rely on the mudflats are declining, and those that stop there twice a year are declining at a faster rate than those that stop only once. If the current trajectory continues, the Yellow Sea—once known as the cradle of China—will become the epicenter of extinction.

For the past 20 years, Israelis and Palestinians alike have approached peace negotiations with the flawed assumption that, in order to reach an agreement, all core issues must be solved simultaneously. As the conflict continues to claim victims on both sides, it’s important to point out that when President Trump’s Middle East envoy, Jason Greenblatt, was looking for an early success in the new administration’s peace efforts, he found it – in water.

Chinese cities are discovering that sewage could provide a clean source of power using new sludge-to-energy technology, writes Jillian Du in January’s most-read post. Chinese cities are looking to U.S. pioneers like Boston and Portland to learn how to incorporate sludge digesters into their waste management and energy infrastructure.

I pulled my horse to a stop along the banks of a little stream, which was wedged between two grassy hills speckled with wildflowers and pika holes, to admire the view of the Tibetan-Qinghai Plateau’s rolling hills evolving into snowcapped mountains.

“Conflicts are 35 percent more likely to be resolved and remain peaceful for 15 years if women are involved,” said Carla Koppell, vice president of the Center for Applied Conflict Transformation at the United States Institute of Peace, at a recent Wilson Center event on the role of women in war, security, and peace.

“There is no healthcare delivery system for non-pregnant 15- to 24-year olds,” said the U.S. Global AIDS Coordinator, Ambassador Deborah Birx, at a recent Wilson Center event on efforts to reduce the prevalence of HIV/AIDS among adolescent girls in sub-Saharan Africa. In 2014, the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR) established the DREAMS program, which aims to create “a health care system where young people interact in a proactive and positive way,” said Birx.

As senior military officers, we see water stress—the lack of adequate fresh water—as a growing factor in the world’s hotspots and conflict areas, many of vital interest to the United States. Our earlier reports have identified a nexus among climate, water, energy, and U.S. national security. We have previously shown how emerging resource scarcity across this nexus can be a threat multiplier and an accelerant of instability. With escalating global population and the impact of a changing climate, we see the challenges of water stress rising with time. It is in this context that we now seek to provide a better understanding of the mechanisms through which water factors into violence and conflict.

Global warming is not just an environmental problem.

Goodman: “It is one of the most serious national security challenges we face. This is a risk issue.”
