As climate change and rapid development take their toll, new ways must be found to manage Asia’s water resources

Brahma Chellaney, Nikkei Asian Review

The record drought ravaging large parts of Asia will end when the annual summer monsoon rains come in June. This will bring much-needed relief to the suffering people in the parched lands — from the millions of residents in Vietnam’s Mekong Delta to more than a quarter of India’s 1.25 billion people. The searing drought has already claimed several hundred lives and destroyed vast swaths of rice paddies and other farms.

But make no mistake: The latest in a string of droughts to hit Asia this century offers a telling preview of the hotter, drier future that awaits much of the continent. This likelihood largely arises from the costs that rapid development, breakneck urbanization, large-scale irrigated farming and lifestyle changes are imposing on natural resources, the environment and climate in the world’s largest and most-populous continent.

Recurrent drought promises to exacerbate Asia’s already-serious water challenges and thus potentially affect economic growth, social peace, and relations between countries or provinces that share rivers or aquifers. In a drought-laden future, thirsty communities, provinces or nations will increase risks of water-related conflict.

Yet little policy attention has been paid to combating droughts because of their episodic character, with scientists still unable to reliably predict the arrival, extent or duration of any drought. Unlike other natural and human-made disasters, from earthquakes and hurricanes to flooding and industrial accidents, a drought is a silently creeping calamity. However, without resource conservation, ecological restoration and more sustainable development, droughts in Asia are likely to become more frequent and severe.

Asia is the world’s most resource-poor continent. Rapid economic growth has brought its limited natural-capital base under increasing pressure. Overexploitation of natural resources, for its part, has created an environmental crisis that is contributing to regional climate change. For example, the Tibetan Plateau, the world’s largest repository of freshwater other than the two poles, is warming at a rate that is more than twice the global average — with potentially serious consequences for Asia’s climate, monsoons and freshwater reserves.

A little-known fact is that Asia, not Africa, is the world’s most water-stressed continent. Water stress is internationally defined as the per capita availability of less than 1,700 cubic meters per year. Asia already has less freshwater per person than any other continent, and some of the world’s worst water pollution.

Water is not just the most undervalued and underappreciated resource; in the coming years, it is likely to be the most contested resource in Asia. This has largely to do with the growing paucity of this life-sustaining resource and Asia’s distinctive water map.

Most important rivers in Asia traverse national boundaries and are thus international systems. Indeed, most Asian nations with land frontiers — with the prominent exception of China, which controls Asia’s riverheads by controlling the Tibetan Plateau — are highly dependent on cross-border water inflows. Such dependency is the greatest in countries like Bangladesh and Vietnam that are located farthest downstream on international rivers.

Against this background, inter-country and intra-country water disputes have become common. Indeed, Asia illustrates that transboundary water resources, instead of linking countries or provinces in a system of hydrological interdependence, are fostering sharpening competition for relative gain. The competition extends to appropriating resources of shared rivers by building dams, reservoirs and other diversions, thus roiling inter-riparian relations. Averting water wars demands rules-based cooperation, water-sharing accords, uninterrupted flow of hydrological data, and dispute-settlement mechanisms.

Asia is already the world’s most dam-dotted continent: It has more dams than the rest of the world combined. But this statistic doesn’t tell the real story: Most of Asia’s dams are in China, which alone has slightly more than half of the world’s approximately 50,000 large dams. With its massive infrastructure of dams and other storage facilities, China has built an impressive capacity to stockpile water for the dry season.

But China’s over-damming of rivers has contributed to river fragmentation (the interruption of natural flows) and depletion, leading to downstream basins drying up or rivers discharging only small amounts of water and nutrient-rich silt into the oceans. China’s dying Yellow River exemplifies this problem. And its cascade of six giant dams on the Mekong, just before it leaves Chinese territory, is being blamed for accentuating the current Southeast Asian drought, with river depletion extending to the delta region, which is a rice bowl of Asia.

Asia’s vulnerability to droughts and other effects of environmental and climate change is being increased by other factors as well, including groundwater depletion and deforestation, especially in the upstream catchment areas. Deforestation is most notable in the Himalayan-Tibetan region, where the great rivers of Asia originate. But it also extends to other regions, including rainforest areas.

Through its environmentally destabilizing impacts, deforestation amplifies the frequency and severity of extreme events such as droughts and floods. The depletion of many Asian swamps — which serve as nature’s water storage and absorption cover — also contributes to a cycle of chronic flooding and drought, besides allowing deserts to advance and swallow up grasslands.

For its part, the extraction of groundwater at rates surpassing nature’s recharge capacity has resulted in a rapidly falling water table across much of Asia. Because groundwater is often a source of supply for streams, springs, lakes and wetlands, the over-exploitation of this strategic resource, which traditionally has served as a sort of drought insurance, creates parched conditions and thus fosters recurrent droughts.

Meanwhile, intensive irrigation in semi-arid regions, including northern China, Central Asia and Pakistan, has helped to create a boom in agricultural exports but exacted heavy transboundary environmental costs. It has caused soil salinity and waterlogging and fostered atmospheric humidity, with climate stability becoming a casualty and dry areas becoming drier.

The entire Asian belt stretching from the Korean Peninsula to the Iran-Afghanistan-Pakistan region is becoming increasingly prone to the ravages of drought. But even before the current drought hit South and Southeast Asia, scientific studies on global drought risk hotspots showed that drought risks were the highest in these two regions, at least in terms of the number of people exposed.

It is past time for Asian policymakers to start addressing drought risks, the core of which is the nexus between water, energy and food. For example, the current drought is roiling world food markets through its destructive impacts on crops. And by reducing cooling-water availability, it is decreasing generation by some power plants, just when electricity demand has peaked.

The drought risks can be reduced by ensuring the protection and ecological restoration of watercourses, securing water-efficiency gains through agricultural-productivity measures, developing drought-resistant crop varieties, improving water quality to offset decrease in water quantity, and utilizing alternative cooling technologies for power generation. Increasing water storage by channeling excess water during the monsoons to artificially recharge aquifers, especially in Asia’s densely populated, economically booming coastal regions, holds promise for coping with droughts.

Policymakers must appreciate that drought risks cannot be lowered without tackling the serious problem of groundwater depletion. Groundwater in Asia is being pumped and consumed by human activities at such a rate that, for example, NASA scientists in the United States observed several years ago that the subterranean reserves in northwest India were vanishing.

Groundwater resources are recklessly exploited because there are few controls in Asia on their extraction. Also contributing to this practice is the fact that, unlike surface water, degradation of groundwater is not visible to the human eye. Surface water and groundwater, however, are linked hydrologically and should be managed as a single resource. A one-water approach is also essential to cut the overreliance of many communities on groundwater supplies.

The specter of permanent water losses is just one reason why Asia’s drought-related challenges demand an integrated, holistic approach. Water, food and energy, for example, must be managed by policymakers not separately but jointly so as to promote synergistic approaches. Also, ecological restoration programs, by aiding the recovery of damaged ecosystems, can help bring wider benefits in slowing soil and water degradation, stemming coastal erosion, augmenting freshwater storage and supply, and controlling droughts.

Without such efforts, the linkages between water stress, sharing disputes, falling water quality and environmental degradation could trap Asia in a vicious cycle. Nature is indivisible: Communities and states cannot thrive for long by bending nature and undercutting environmental sustainability.

A severe drought currently ravaging Southeast and South Asia has helped spotlight China’s emergence as the upstream water controller in Asia through a globally unparalleled hydro-engineering infrastructure centered on damming rivers. Indeed, Beijing itself has highlighted its water hegemony over downstream countries by releasing some dammed water for drought-hit nations in the lower Mekong River basin.

In releasing what it called “emergency water flows” to downstream states over several weeks from one of its six giant dams — located just before the Mekong flows out of Chinese territory — China brashly touted the utility of its upstream structures in fighting droughts and floods.

But for the downriver countries, the water release was a jarring reminder of not just China’s newfound power to control the flow of a life-sustaining resource, but also of their own reliance on Beijing’s goodwill and charity. With a further 14 dams being built or planned by China on the Mekong, this dependence on Chinese goodwill is set to deepen — at some cost to their strategic leeway and environmental security.

Armed with increasing leverage, Beijing appears to be pushing its Lancang-Mekong Cooperation (LMC) initiative as an alternative to the lower-basin states’ Mekong River Commission, which China has spurned over the years. Indeed, having its cake and eating it too, China is a dialogue partner but not a member of the commission, underscoring its intent to stay clued in on the discussions, without having to take on any legal obligations.

The LMC — a broad-based political initiative emphasizing Chinese “cooperation” and subsuming China’s pet projects, such as “One Belt, One Road” — is intended to help marginalize the commission, an institution with legally binding rules and regulations. China’s refusal to join the 1995 Mekong treaty, which created the commission, has stunted the development of an inclusive, rules-based basin community to deal with water- and environmental-related challenges.

It was not a coincidence that Beijing’s water release started shortly before the March 23 inaugural LMC summit of the leaders of the six Mekong basin countries in Sanya, in the Chinese province of Hainan.

The LMC project is also designed to overshadow the U.S.-sponsored Lower Mekong Initiative, which seeks to sideline Chinese opposition to the Mekong treaty by promoting integrated cooperation among the quintet of lower-Mekong basin states (also known as the “Mekong Five”) — Cambodia, Laos, Myanmar, Thailand and Vietnam. The Mekong treaty was concluded as China completed its first large dam on the river.

The Mekong, Southeast Asia’s lifeline that is running at a record low since late last year, is just one of the international rivers China has dammed. It has also targeted the Yarlung Tsangpo (Brahmaputra), the Arun, the Indus, the Sutlej, the Irtysh, the Illy, the Amur and the Salween. These rivers flow into India, Nepal, Kazakhstan, Russia or Myanmar.

Asia’s water map changed fundamentally after the communists took power in China in 1949. It wasn’t geography but guns that established China’s chokehold on almost every major transnational river system in Asia, the world’s largest and most-populous continent.

By forcibly absorbing the Tibetan Plateau (the giant incubator of Asia’s main river systems) and Xinjiang (the starting point of the Irtysh and the Illy), China became the source of transboundary river flows to the largest number of countries in the world, extending from the Indochina Peninsula and South Asia to Kazakhstan and Russia. Beijing’s claim over these sprawling territories, which make up more than half of China’s landmass today, drew from the fact that they were imperial spoils of the earlier foreign rule in China under the Manchu Qing dynasty (1644 to 1911) and the Mongol Yuan dynasty (1271 to 1368).

Before the communists seized power, China had only 22 dams of any significant size. But now, it boasts more large dams on its territory than the rest of the world combined.  If dams of all sizes and types are counted, their number in China surpasses 85,000. Strongman Mao Zedong initiated an ambitious dam-building program, but the majority of the existing dams were built in the period after him.

China’s dam frenzy, however, shows no sign of slowing. The country’s dam builders, in fact, are shifting their focus from the dam-saturated internal rivers (some of which, like the Yellow, are dying) to the international rivers, especially those that originate on the water-rich Tibetan Plateau.  This raises fears that the degradation haunting China’s internal rivers could be replicated in the international rivers.

China, ominously, has graduated to erecting mega-dams. Take its latest dams on the Mekong: the 4,200-megawatt Xiaowan (taller than the Eiffel Tower in Paris) and the 5,850-megawatt Nuozhadu, with a 190-square-kilometer reservoir. Either of them is larger than the current combined hydropower-generating capacity in the lower Mekong states.

Despite its centrality in Asia’s water map, China has rebuffed the idea of a water-sharing treaty with any neighbor.

Against this background, concern is growing among is downstream neighbors that China is seeking to turn water into a potential political weapon. After all, by controlling the spigot for much of Asia’s water, China is acquiring major leverage over its neighbors’ behavior in a continent already reeling under very low freshwater availability.

Asia’s annual water availability is barely one-tenth of that in South America, Australia, and New Zealand; not even one-fifth of North America’s; nearly one-third of Europe’s; and a quarter less than Africa’s. Yet the world’s most rapidly growing demand for water for industry, food production and municipal supply is in Asia.

In the Mekong basin, China has denied that it is stealing shared waters or that its existing dams have contributed to river depletion and recurrent drought in the downstream region. Yet, by ramping up construction of additional giant dams, China has virtually ensured long-term adverse impacts on the critical river system. Indeed, with Chinese assistance, landlocked Laos also plans to build more Mekong dams in order to make hydropower exports, especially to China, the mainstay of its economy.

China is clearly not content with being the world’s most dammed country, and the only thing that could temper its dam frenzy is a prolonged economic slowdown at home. Flattening demand for electricity due to China’s already-slowing economic growth, for example, offers a sliver of hope that the Salween River — which flows into Myanmar and along the Thai border before emptying into the Andaman Sea — could be saved, even if provisionally, from the cascade of hydroelectric mega-dams that Beijing has planned to build on it.

More fundamentally, China’s unilateralist approach underscores the imperative for institutionalized water cooperation in Asia, based on a balance between rights and obligations. Renewed efforts are needed to try and co-opt China in rules-based cooperation.

Asia’s water woes are worsening. Already the world’s driest continent in per capita terms, Asia now faces a severe drought that has parched a vast region extending from southern Vietnam to central India. This has exacerbated political tensions, because it has highlighted the impact of China’s dam-building policy on the environment and on water flows to the dozen countries located downstream.

Today’s drought in parts of Southeast and South Asia is the worst in decades. Among the hardest-hit areas are Vietnam’s Mekong Delta (a rice bowl of Asia) and central highlands; 27 of Thailand’s 76 provinces; parts of Cambodia; Myanmar’s largest cities, Yangon and Mandalay; and areas of India that are home to over a quarter of the country’s massive population.

Droughts may not knock down buildings, but they carry high social and economic costs. Millions of Asians now confront severe water shortages, and some have been forced to relocate. Myanmar, Thailand, and Cambodia have had to scale back traditional water festivals marking their New Year. The High Court of Bombay moved the world’s biggest and wealthiest cricket tournament, the Indian Premier League, out of the state of Maharashtra. In one Maharashtra county, the local authorities, fearing violence, temporarily banned gatherings of more than five people around water storage and supply facilities.

Meanwhile, the mounting drought-related losses in some of the world’s top rice-producing countries – Thailand, Vietnam, and India – threaten to roil the world’s already tight rice market. Barely 7% of global rice output is traded internationally, because much of it is consumed where it is produced – in Asia.

Rice losses have been particularly significant in Thailand and Vietnam, which account for half of all rice exports and almost three-quarters of this decade’s projected export growth. Some 230,000 hectares of paddy rice cultivation has been destroyed just in Vietnam’s Mekong Delta, where depleted river flows have led to saltwater intrusion from the South China Sea, rendering nearly 10% of the rice farms potentially infertile.

This drought may be unprecedented, but it is not an anomaly. On the contrary, environmental challenges in Asia, such as ecosystem degradation, groundwater depletion, the contamination of water resources, the El Niño tropical weather pattern, and the effects of global warming are causing droughts to become increasingly frequent – and increasingly severe.

Even without droughts, Asia would be facing formidable water constraints. The annual amount of available fresh water per capita in the region (2,816 cubic meters) already is less than half the global average (6,079 cubic meters). As the region pursues rapid economic development, characterized by massive increases in resource consumption and serious environmental damage, its water constraints are tightening further. The challenge is compounded by Asians’ changing dietary preferences, particularly higher consumption of meat, the production of which is notoriously water-intensive.

While Asia’s resource-hungry economies can secure fossil fuels and mineral ores from distant lands, they cannot import water, which is prohibitively expensive to transport. So they have been overexploiting local resources instead – a practice that has spurred an environmental crisis, advancing regional climate change and intensifying natural disasters like droughts.

As a result, Asia, which accounts for 72% of the world’s total irrigated acreage, now faces a dilemma: It must grow enough food to meet rising demand, while reducing the amount of water that goes toward irrigation. Unless Asia resolves it, economic development will be imperiled, with major consequences for the entire global economy.

Yet the continent’s water crisis is only worsening. According to a recent MIT study, there is a “high risk” that Asia’s water stress could worsen to water scarcity by 2050. Water-sharing disputes between countries or provinces already are increasingly frequent, owing to the proliferation of dam projects that can adversely affect downstream flows – an approach that represents a continuing preference for supply-side approaches over smart water management.

The main culprit in this regard is China, which has heavily dammed the Mekong, Southeast Asia’s lifeline. In the current lean season, which will last until the monsoon rains arrive in June, the lower Mekong is, according to a recent United Nations report, running at “its lowest level since records began nearly 100 years ago.”

China is now trying to play savior, by releasing an unspecified quantity of water from one of its six upstream mega-dams to “accommodate the concerns” of drought-stricken countries. China’s rulers have touted the move as underscoring the effectiveness of upstream “water facilities” in addressing droughts and containing floods.

Of course, in reality, all of this simply highlights the newfound reliance of downriver countries on Chinese goodwill – a dependence that is set to deepen as China builds 14 more dams on the Mekong. The environmental impact of these projects is sure to exacerbate further the ecological challenges, including drought, already facing Asia.

This competitive approach is putting Asia on a dangerous path, which can lead only to more environmental degradation, slower economic development, and even water wars. It is time to change course and embark on the path of rules-based cooperation, based on water-sharing accords, the free flow of hydrological data, and dispute-settlement mechanisms.

Asian countries must work together to ensure greater efficiency in water consumption, increase the use of recycled and desalinated water, and promote innovative solutions that advance conservation and adaptation efforts. To this end, governments must phase out state subsidies that have encouraged profligate water use, such as in agriculture, and focus on building new market mechanisms and effective public-private partnerships.

None of this will be possible without China’s cooperation. Indeed, if China does not abandon its current approach – from its “water grab” in the Mekong and other international rivers to its “territorial grab” in the South China Sea – the prospects for a rules-based order in Asia could perish forever.

China, with its frenzied damming of rivers and unbridled exploitation of mineral wealth on the resource-rich Tibetan Plateau, is compounding the damage to Himalayan ecosystems by encouraging its bottled-water companies to tap the already-stressed glaciers.

HONG KONG – When identifying threats to Himalayan ecosystems, China stands out. For years, the People’s Republic has been engaged in frenzied damming of rivers and unbridled exploitation of mineral wealth on the resource-rich Tibetan Plateau. Now it is ramping up efforts to spur its bottled-water industry – the world’s largest and fastest-growing – to siphon off glacier water in the region.

Nearly three-quarters of the 18,000 high-altitude glaciers in the Great Himalayas are in Tibet, with the rest in India and its immediate neighborhood. The Tibetan glaciers, along with numerous mountain springs and lakes, supply water to Asia’s great rivers, from the Mekong and the Yangtze to the Indus and the Yellow. In fact, the Tibetan Plateau is the starting point of almost all of Asia’s major river systems.

By annexing Tibet, China thus changed Asia’s water map. And it is aiming to change it further, as it builds dams that redirect trans-boundary riparian flows, thereby acquiring significant leverage over downriver countries.

But China is not motivated purely by strategic considerations. With much of the water in its rivers, lakes, and aquifers unfit for human consumption, pristine water has become the new oil for China – a precious and vital resource, the overexploitation of which risks wrecking the natural environment. By encouraging its companies to tap Himalayan glaciers for premium drinking water that can satisfy a public skeptical about the safety of tap water, China is raising the environmental stakes throughout Asia.

Though much of the bottled water currently sold in China comes from other sources – chemically treated tap water or mineral water from other provinces – China seems to think that the bottling of Himalayan glacier water can serve as a new engine of growth, powered by government subsidies. As part of the official “Share Tibet’s Good Water with the World” campaign, China is offering bottlers incentives like tax breaks, low-interest loans, and a tiny extraction fee of just CN¥3 ($0.45) per cubic meter (or 1,000 liters). According to a ten-year plan unveiled by Chinese authorities in Tibet last fall, extraction of glacier water will increase more than 50-fold in just the next four years, including for export.

Some 30 companies have already been awarded licenses to bottle water from Tibet’s ice-capped peaks. Two popular brands in China are Qomolangma Glacier, sourced from a supposedly protected reserve linked to Mount Everest, on the border with Nepal, and 9000 Years, named after the assumed age of its glacial source. A third, Tibet 5100, is so named because it is bottled at a 5,100-meter-high glacial spring in the Nyenchen Tanglha range that feeds the Yarlung Tsangpo (or Brahmaputra River) – the lifeblood of northeastern India and Bangladesh.

Ominously, the Chinese bottled-water industry is sourcing its glacier water mainly from the eastern Himalayas, where accelerated melting of snow and ice fields is already raising concerns in the international scientific community. Glaciers in the western Himalayas, by contrast, are more stable and could be growing. Even the Chinese Academy of Sciences has documented a sharp decrease in the area and mass of eastern Himalayan glaciers.

One of the world’s most bio-diverse but ecologically fragile regions, the Tibetan Plateau is now warming at more than twice the average global rate. Beyond undermining the pivotal role Tibet plays in Asian hydrology and climate, this trend endangers the Tibetan Plateau’s unique bird, mammal, amphibian, reptile, fish, and medicinal-plant species.

Nonetheless, China is not reconsidering its unbridled extraction of Tibet’s resources. On the contrary, since building railways to Tibet – the first was completed in 2006, with an extension opened in 2014 – China’s efforts have gone into overdrive.

Beyond water, Tibet is the world’s top lithium producer; home to China’s largest reserves of several metals, including copper and chromite (used in steel production); and an important source of diamonds, gold, and uranium. In recent years, Chinese-controlled companies have launched a mining frenzy on the plateau that not only damages landscapes sacred to Tibetans, but also is eroding Tibet’s ecology further – including by polluting its precious water.

These are precisely the kinds of actions that caused China’s water crisis in the first place. Instead of learning the lessons of its past mistakes, China is compounding them, forcing a growing number of people and ecosystems to pay the price for its imprudent approach to economic growth.

Indeed, China has implemented no effective safeguards against adverse impacts from intensive water mining. Bottled water is being sourced even from protected reserves where glaciers are already in retreat. Meanwhile, the glacier-siphoning boom is attracting highly polluting ancillary industries, including manufacturers of plastic water bottles.

Make no mistake: Glacier-water mining has major environmental costs in terms of biodiversity loss, impairment of some ecosystem services due to insufficient runoff water, and potential depletion or degradation of glacial springs. Moreover, the process of sourcing, processing, bottling, and transporting glacial water from the Himalayas to Chinese cities thousands of miles away has a very large carbon footprint.

Bottling glacier water is not the right way to quench China’s thirst. A better alternative, both environmentally and economically, would be to boost investment in treatment facilities to make tap water safe in cities. Unfortunately, China seems determined to remain on its current course – an approach that could do irreparable and severe damage to Asia’s environment, economy, and political stability.
