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. 

At the G20 Summit in Hamburg early July 2017, leaders of the world’s strongest economies issued a joint statement reaffirming their commitment to the Paris Climate Accord. President Trump—the lone outsider—had announced in early June he would withdraw the United States from the agreement. As China doubles down on meeting its Paris targets, the chasm between the world’s two largest emitters and energy consumers continues to widen as previous joint efforts to curb carbon emissions fade away. Post-summit headlines focusing on the “G19” nations suggest America has abandoned international cooperation against climate change. But some U.S. cities and states are continuing the climate fight with their Chinese counterparts.

“All of Reykjavik might be able to fit in that apartment block,” remarks Einar Magnusson, the vice president of business development for Iceland-based Arctic Green Energy Corporation (AGEC), as he drives past miles and miles of Beijing’s residential skyscrapers. Following Jiang Zemin’s visit to Iceland in 2002 – the first-ever by a Chinese President – the two nations opened a new chapter in their partnership, which was originally founded upon shared strategic interests. China’s interest in cleaner energy sources has led to a fruitful area of cooperation with Iceland, where geothermal plants generate 66 percent of the country’s primary energy and provide nine in ten households with heat.

On Wednesday, June 21, 2017, authorities in Beijing, Tianjin, and Hebei warned residents to prepare for a storm that could trigger flooding and possibly landslides. Flood warnings have become all too common in China: In 2013, more than 230 Chinese cities experienced floods. But Mother Nature is not entirely to blame; the cities’ outdated drainage systems are quickly overwhelmed and sprawling concrete gives stormwater runoff no place to go.

Coal — the reigning king of China’s energy sector — generates 74 percent of the country’s electricity and is the main source of the staggering air pollution blanketing Chinese cities. Prompted in large part by the air pollution problem, the Chinese leadership has begun to pivot away from coal by strengthening monitoring and enforcement to limit coal-fired power plant emissions, piloting CO₂ emissions trading projects, accelerating expansion of renewables, and committing to CO₂ reductions in the Paris climate agreement.

With a capacity of 3,300 MW, Sichuan’s Ertan Hydropower Plant—once China’s largest—promised to alleviate provincial energy shortages and spur economic growth when it began generating electricity in 2000. However, in what came to be known as the “Ertan Incident,” provincial officials halted all clean energy generation in Sichuan soon after the plant came online. The Sichuan power company was obligated by law to buy half of its power from coal-fired power plants, regardless of their inefficiency or environmental impacts. To keep the coal burning, the dam was forced to operate at a major financial loss.

In 2016, the Environmental Protection Agency charged its federal advisory committee with exploring how citizen science and crowdsourcing should be integrated into the agency’s mission. The resulting report eloquently describes how if the environment is to be protected then it’s the duty of all – the government, institutions, and citizens – to work together to achieve this.

In a world rapidly churning out unpredictable political shocks, intelligence analysts occasionally need to clear their heads of the daily barrage of newsworthy events and instead work with simple theories that discern the direction and speed of trends and help predict their outcomes. Political demography, the study of population age structures and their relationships to political trends and events, has helped some analysts predict geopolitical changes in a world that, from time to time, appears utterly chaotic.
