China’s Growing Water Risk Factor

When it comes to climate change, China’s status as the world’s largest emitter is typically the focus of media and policy attention.
But while China’s central role in mitigating climate change is relatively well known in the outside world, less well appreciated is the importance that climate change adaptation plays in driving Beijing’s climate policy and many of its infrastructure investments.
China is the world’s largest emitter…
…but it also has some of the most ambitious investments in adaptation
The importance of adaptation stems both from fact that China is heavily exposed to climate risks, and the fact that China has made some of the world’s most ambitious investments in key adaptation infrastructure like water conservancy. Indeed, while the world’s focus is often on whether Beijing’s big bets on clean technology will cut emissions, arguably even more significant is how its view of climate risks drives its climate policy more broadly.
When I spent a year in Beijing researching China’s climate policy in the run-up to the Copenhagen climate conference in 2009, many of my contacts pointed to one climate-related concern in particular: changes in the distribution and availability of water in China’s major river basins.
That concern points to the fact that climate adaptation, water management, and water conservancy are closely linked in the minds of China’s senior leaders. This linkage in turn suggests that to understand China’s climate policy, and where it is headed, observers should focus at least as much on water as on energy. That is something I explore in my latest book, China’s Next Act: How Sustainability and Technology are Reshaping China’s Rise and the World’s Future.
To understand China’s climate policy, observers should focus at least as much on water as on energy
The perception of water-related climate risk has long played an under-appreciated role in shaping China’s climate policy. The 2007 National Climate Change Program prepared in advance of Copenhagen, the first major policy document to address the climate issue, emphasized China’s vulnerability to climate-linked disasters, especially flooding and drought.
It is significant that Beijing has continued to cite highlight water-related climate risks in submissions ahead of major international climate conferences. An officially-sanctioned research paper issued just before the Glasgow climate conference last December found for example that China has faced an increase in average temperatures higher than the global average, exacerbating water shortages.
As this emphasis suggests, China is indeed especially vulnerable to water-related climate risks. In fact, among large economies it is arguably the single most highly exposed to these risks. A 2021 World Bank report on climate vulnerability, for example, ranked China 61st among 181 countries, and noted that “Even in proportion to its large size and economy, China’s vulnerability to climactic hazards is high.”
Its outsized vulnerability reflects 2 factors: geography & extensive urbanization
This outsize vulnerability reflects two primary factors: geography, and especially the fact that several of China’s largest urban areas are located in low-lying coastal and estuarine areas while the Tibetan Plateau, often referred to as “the third pole,” is experiencing more rapid warming than other regions; and China’s extensive urbanization, which has created a dense cluster of vulnerable infrastructure and assets.
China’s vulnerability to water-related climate risks has been dramatically, and tragically, highlighted by three consecutive summers of record-breaking flooding. Though China has long suffered catastrophic flooding, with average annual damages estimated at $18 billion, recent flood events have been unusual in their intensity.
Catastrophic flooding is a big issue with avg annual damages at $18bn…
During the summer of 2020, precipitation in central China was estimated by state media to have been roughly 20% higher than normal, causing such severe flooding that observers began to question the integrity of the mammoth Three Gorges Dam.
The following summer, flash floods led to the deaths of dozens of people, several of whom were trapped on a subway in Zhengzhou, Henan Province. The portion of China’s population exposed to these risks is expected to continue to increase, with an additional 27-35 million people affected annually by the mid-twenty-first century, largely thanks to climate change.
…but increasing climate impacts = more capacity for adaptation
Yet if China’s exposure to flooding and water shortage is increasing, so too is its capacity for adaptation. China has long boasted an under-appreciated, and under-studied, disaster response capability, and one in which Beijing has continued to invest. Even less well appreciated is the adaptive capacity afforded by China’s massive investments in water infrastructure.
These include China’s many large dams, which apart from helping to control flooding also create substantial storage capacity, helping to mitigate periods of water shortage. Even a decade ago, China possessed 10% of the entire world’s water storage capacity. Just as important, China has built a network of inter-basin water transfers that link major storage dams and help to even out regional variations in water availability. In combination, this system of reservoirs and conduits means that China has a formidable defense against drought as well as flooding.
“…China is possibly the world’s best example of attempting to do both [ambitious mitigation & adaptation policies]
Thanks to Xi Jinping’s pledge to reduce China’s carbon dioxide emissions to net zero by 2060, Beijing has already put forward one of the world’s most ambitious climate commitments. Yet even if China, and the rest of the world, can keep these commitments to reduce emissions, it will continue to wrestle with sea level rise and other climate change effects. In some respects, investment in adaptation both reflects this reality and hedges against the possibility that the world will not meet its emissions reduction goals.
There is little contradiction or tension between having ambitious policies both to mitigate and adapt to climate change, and in fact China is possibly the world’s best example of attempting to do both, and thereby addressing both the water and energy dimensions of climate change. China’s example in enhancing adaptive capacity is one to which the outside world should pay more heed.
