In early January of this year, China’s “National Sword” policy banned imports of non-industrial plastic waste. The ban forces exporting countries to find new dumping grounds for their waste, which is estimated to total nearly 111 million metric tons by 2030. China’s decision has exposed deep structural flaws and interdependencies in the global waste management system. Western countries that have long depended on China to take their garbage are now struggling to deal with mounds of plastic trash, while China lacks the low-priced labor needed to effectively sort and process waste.

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.  

Just days before the 2016 Summer Olympics began in Rio de Janeiro, the Brazilian city faced an unsavory problem: how to handle its overwhelming sewage. Nearly half of Rio’s municipal wastewater flowed untreated into Guanabara Bay, where the waters were so polluted by sludge that direct contact was deemed a health hazard to Olympic athletes.

“Water may be the most important issue we face for the next generation,” writes President Donald J. Trump on the first page of the first-ever U.S. Global Water Strategy. Prepared by the U.S. State Department and released in mid-November, the landmark report was required by Congress’ bipartisan Senator Paul Simon Water for the World Act of 2014. During the public comments phase, the New Security Beat published recommendations from its fellows and experts. Now that it is out, we’ve asked them to share their thoughts on the final report.

Six years of brutal warfare have destroyed basic infrastructure in Yemen, Libya, and Syria.  While U.S. and European governments have been largely preoccupied with providing immediate assistance and dealing with refugees, international humanitarian organizations—such as the International Committee of the Red Cross and Doctors without Borders—are focusing on how to repair, maintain, and safeguard the facilities that provide essential services like clean water, sanitation, and electricity.  Yet these efforts are hindered by lack of resources, protracted violence, and—most insidiously—by the warring parties’ intentional targeting of humanitarian actors and environmental infrastructure. Just as the extensive damage from hurricanes in the Caribbean and southeastern United States has underscored the need for more resilient infrastructure, the wars of the Middle East show that protecting infrastructure is key to protecting civilians caught up in conflict.

Chinese cities are being encircled by untreated sludge—a pungent, viscous mixture of human excreta and stormwater runoff. Four years ago in Beijing, trucks loaded with untreated sludge from the city’s largest wastewater treatment plant were illegally dumping mountains of sludge in the outskirts of the capital as “free fertilizer” for peri-urban farms. Similarly, in the southern China city of Guangzhou, disposing toxic sludge into the nearby river required nothing more than a hired boat. From the far western desert city of Urumqi to the eastern metropolis of Shanghai, more and more of China’s cities are struggling to manage mountains of sludge and municipal waste, as well as floods of wastewater and stormwater runoff. 

Launched in Beijing in 2013, the highly successful grassroots “Empty Your Plate” campaign encourages Chinese consumers to eliminate food waste from their meals. Starting with blog posts on Weibo (China’s equivalent of Twitter), this campaign rapidly swept the entire country and attracted support from the central government, which later issued a series of policies urging restaurants to use smaller dishes and remove minimum charges. However, the volume of food waste in China is still astonishing.

In Jordan—one of the driest, most water poor countries in the world—population growth is straining the country’s aging infrastructure and limited water resources. As the Jordan country director for the Millennium Challenge Corporation (MCC), I’ve met urban residents and business owners who have only received water from the city utility once every two weeks, relying on storage tanks to fill the gaps. I’ve spoken with water utility managers who could no longer keep up with urgent repairs, leading to bursting water pipes and sewage overflowing into streets. And farmers in the Jordan Valley have told me that each year their wells have grown drier, and they feared the next generation would be forced to give up farming olives, tomatoes, grapes, and strawberries.
