BRAHMA CHELLANEY
Asia’s futurity is inextricably tied to the Himalayas, the world’s tallest mount hit in addition to the source of the water-stressed continent’s major river systems. Yet reckless national projects are straining the region’s frail ecosystems, resulting inward a mounting safety threat that extends beyond Asia. With elevations rising dramatically from less than 500 meters (1,640 feet) to over 8,000 meters, the Himalayas are habitation to ecosystems ranging from high-altitude alluvial grasslands in addition to subtropical broadleaf forests to conifer forests in addition to alpine meadows. Stretching from Myanmar to the Hindu-Kush watershed of Central Asia, the Himalayas play a key operate inward driving Asia’s hydrological cycle in addition to conditions in addition to climate patterns, including triggering the annual summertime monsoons. Its 18,000 high-altitude glaciers shop massive amounts of freshwater in addition to serve inward wintertime every bit the world’s second-largest rut sink afterwards Antarctica, therefore helping to moderate the global climate. In summer, however, the Himalayas plow into a rut source that draws the monsoonal currents from the oceans into the Asian hinterland.

Its 18,000 high-altitude glaciers shop massive amounts of freshwater in addition to serve inward wintertime every bit the world’s second-largest rut sink afterwards Antarctica, therefore helping to moderate the global climate. In summer, however, the Himalayas plow into a rut source that draws the monsoonal currents from the oceans into the Asian hinterland. The Himalayas are forthwith plain of study to accelerated glacial thaw, climatic instability, in addition to biodiversity loss. Five rivers originating on the Great Himalayan Massif – the Yangtze, the Indus, the Mekong, the Salween, in addition to the Ganges – rank amid the world’s 10 most endangered rivers.
From large-scale dam construction to the unbridled exploitation of natural resources, human action is clearly to blame for these potentially devastating changes to the Himalayan ecosystems. While all the countries inward the portion are culpable to some extent, none is doing every bit much impairment every bit China.
Unconstrained past times the kinds of grassroots activism seen in, say, democratic India, Cathay has used massive, but frequently opaque, construction projects to curvature nature to its volition in addition to trumpet its rising every bit a groovy power. This includes a globally unmatched inter-river in addition to inter-basin water-transfer infrastructure alongside the capacity to motion over 10 billion cubic meters (13 billion cubic yards) through 16,000 kilometers (9,940 miles) of canals.
China’s reengineering of natural river flows through damming – one-fifth of the country’s rivers forthwith accept less H2O flowing through them each twelvemonth than is diverted to reservoirs – has already degraded riparian ecosystems in addition to caused 350 large lakes to disappear. With these water-diverting projects increasingly focused on international, rather than internal, rivers – inward item those inward the Tibetan Plateau, which covers nearly three-quarters of the Himalayan glacier expanse – the environmental threat extends far beyond China’s borders.
And dams are merely the beginning. The Tibetan Plateau is likewise the plain of study of Chinese geo-engineering experiments, which aim to own pelting inward its arid northward in addition to northwest. (Rain inward Tibet is concentrated inward its Himalayan region.) Such activities threaten to suck wet from other regions, potentially affecting Asia’s monsoons. Ominously, such experiments are an extension of the Chinese military’s weather-modification program.
Moreover, every bit if to substantiate the Chinese advert for Tibet, Xizang(“Western Treasure Land”), Cathay is draining mineral resources from this ecologically frail but resource-rich plateau, without regard for the consequences. Already, copper mine tailings are polluting waters inward a Himalayan portion sacred to Tibetans, which they telephone telephone Pemako (“Hidden Lotus Land”), where the world’s highest-altitude major river, the Brahmaputra (Yarlung Tsangpo to Tibetans), curves around the Himalayas earlier entering India.
Last fall, the once-pristine Siang – the Brahmaputra’s primary artery – all of a precipitous turned blackish gray every bit it entered India, potentially because of China’s upstream tunneling, mining, or damming activity. To endure sure, the Chinese regime claimed that an earthquake that struck southeastern Tibet inward mid-November “might accept led to the turbidity” inward the river waters. But the H2O had overstep unfit for human consumption long earlier the quake.
In whatever case, Cathay is non letting up. It has, for example, eagerly launched large-scale operations to mine precious minerals similar gilded in addition to argent inward a disputed expanse of the eastern Himalayas that it seized from Republic of Republic of India inward a 1959 armed clash.
Meanwhile, China’s bottled-water manufacture – the world’s largest – is siphoning “premium drinking water” from the Himalayas’ already-stressed glaciers, peculiarly those inward the eastern Himalayas, where accelerated melting of snowfall in addition to H2O ice fields is already conspicuous. Unsurprisingly, this is causing biodiversity loss in addition to impairment of ecosystem services.
Across the Himalayas, scientists study large-scale deforestation, high rates of loss of genetic variability, in addition to species extinction inward the highlands. The Tibetan Plateau, for its part, is warming at almost three times the average global rate. This holds environmental implications that extend far beyond Asia.
The towering Himalayan Highlands, peculiarly Tibet, influence the Northern Hemisphere’s atmospheric-circulation system, which helps to carry warm air from the equator toward the poles, sustaining a variety of climate zones along the way. In other words, Himalayan ecosystem impairment volition probable behavior upon European in addition to North American climatic patterns.
Halting rampant environmental degradation inward the Himalayas is forthwith urgent, in addition to it is possible alone through cooperation amid all members of the Himalayan basin community, from the lower Mekong River portion in addition to Cathay to the countries of southern Asia. To pick out nigh such cooperation, however, the entire international community volition accept to apply pressure level to rein inward China’s reckless environmental impairment, which is past times far the greatest source of risk.
