China's thirst threat

Brahma Chellaney 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.
