The Arctic is believed to be a pristine environment, far removed from littered city streets and toxic industrial emissions. I study human pollution and I found it hard to believe that my fellow researchers and I would find so much litter out here. It was even harder to believe that what we uncovered closely resembled the contents of my own closet, over 3,000 kilometers (2,000 miles) away in Toronto.

One of the biggest challenges facing China’s future development is water, which must support the country’s 1.4 billion people and booming industries. Despite being one of the top five countries with the largest freshwater resources, on a per capita basis, China faces serious water shortages which are further compounded by a highly uneven spatial distribution and precipitation: the densely populated north suffers from acute water shortages whereas the south is prone to severe floods. To optimize the allocation of water resources, China has embarked on the construction of a mega engineering project, the South North Water Diversion project (SNWD).

Better access to safe drinking water and sanitation around the world could prevent the deaths of 297,000 children aged under 5 years from diarrhea each year. Likewise, the risk of infection of other common infectious diseases including cholera, hepatitis A, typhoid, and most recently – the coronavirus, can be reduced by improving access to clean water and sanitation facilities. 

Some older Wuhan residents still talk about paddling across the city in their boats, traversing the 100-plus lakes that were once connected by a network of canals. This once-leisurely activity takes on different meaning today as citizens navigate some of the worst floods in decades. Hubei Province, where Wuhan is the capital, is among the 27 central and southern Chinese provinces affected by floods that have caused CNY 86 billion (USD $12.3 billion) in nationwide economic losses in June and July of this year. 

China is one of the “thirstiest” countries in the world with a per capita water availability a quarter of the United States. With population, pollution, and water shortages growing unabatedly, reclaimed water (e.g., treating wastewater to drinking water standards) could be the answer to China’s water insecurity. In China, extensive research in the 1980s into water reclamation and urban investments supporting infrastructure in the 2000s sparked production capacity in the country to rise from 63 billion gallons a day to 236 billion gallons per day between 2009 to 2015. Today, however, reclaimed water is a mere drop in the bucket meeting less than 1 percent of total urban water use. China could look to the tiny Southeast Asian city-state of Singapore to learn how it tapped reclaimed water to turn its water-scarce tiny island into a high-tech hydrohub. 

Coal has long been China’s “black gold,” supplying over half of the nation’s electricity. Yet as coal’s energy share decreases due to domestic action to reduce air pollution and greenhouse gas emissions, a new coal industry is emerging. In China’s arid northwest, eight plants are pulverizing coal chunks and “cooking” coal powder into something more valuable than power—or maybe even gold. These coal conversion plants, soon numbering over 20, churn out chemicals to produce plastic.

China’s war on pollution and goals to lower carbon emissions are noteworthy as the United States takes a back seat in the global energy transition. Cleaner air and low carbon efforts in China could significantly change the country’s environmental health story and contribute to global efforts to lower greenhouse gas emissions. However, China’s energy reforms look less green now than they seemed after Paris in 2015. While China’s rate of increase in CO₂ emissions has slowed and the share of renewables in its energy mix continues to grow, the Chinese government’s pursuit of clean air along its east has shifted more polluting and water-intensive coal-fired power development into the country’s west. To continue to lead the way in this “Asian Century,” China must further incorporate water-saving reforms into its energy and environment plans.

A quarter of the coal that powers China’s economy is mined in Inner Mongolia, one of the country’s most water-scarce provinces with only slightly under two percent of China’s total water resources. The coal-rich city of Ordos, which produces nearly 70 percent of all the coal in Inner Mongolia, is bookended by expanding deserts—Kubuqi to the north and Maowushu to the south—and may one day run out of water and face a “Day Zero” like Cape Town in South Africa. Both the central and local governments are promoting a number of efforts to create new water supplies in Ordos, such as treating brackish waters and trading water rights. To learn more, the China Energy & Environment Forum recently interviewed Shaofeng Jia, the Deputy Director of Water Resources Research Center at the Chinese Academy of Sciences, who recently completed an extensive study on water-energy confrontations in Inner Mongolia.
