[ALOCHONA] Is it opportune to withdrawarmy from CHT?



INDIAN 'GEO-STRATEGISTS' CRYING WOLF
 
Is it opportune to withdrawarmy from CHT?
 
Sadeq Khan
 
An Inter-Service Public Relations (ISPR) press release on July 29 confirmed that the government is in the process of withdrawing a brigade of army troops, including three infantry battalions and 35 security camps, from the vulnerable districts of Chittagong Hill Tracts (CHT).
   'This withdrawal process will start immediately and will conclude in September 2009,' the release said.

   'As Prime Minister Sheikh Hasina is pledged-bound to implement the Chittagong Hill Tracts Treaty signed in 1997, she directed withdrawal of the troops from the region,' an official at the army headquarters told a newsman.
   The pull-out was originally planned for June-July, according to the official.
   This will be the biggest ever army withdrawal from the area after CHT peace deal was signed, said the statement.

   The 1996-2001 Awami League government concluded a peace deal in 1997, with Parbatya Chattagram Jana Sanghati Sangstha (PCJSS), aiming to end two decades of bloody insurgency in the region.
   A total of 200 security camps were withdrawn in different phases since the deal was signed, said the statement.
   Contacted for comment on the fresh government decision of army pullout, a senior leader of the PCJSS, the militant organisation of the dominant tribe in CHT, refrained from making any observation.

   The conflict in the CHT, that accounts for nearly one-tenth of the country's total land mass dates back to 1962 when the then Pakistan government built Kaptai hydro-electricity plant that caused displacement of as many as 100,000 of the native people. In post-independence Bangladesh, rebel Shanti Bahini, the armed wing of the PCJSS, launched its first offensive on an army convoy in 1977 in strong protest against the then government's rehabilitation scheme for plain land people in the CHT areas..

   The government increased army deployment as the Shanti Bahini continued hit and run raids and ransom collection, from a cross the Indian border, until signing of the treaty.
   It is noteworthy that some dissident sleeper units of erstwhile Shanti Bahini had spurned the deal and stayed back in India on the other side of CHT borders. They are in a position to resume insurgency. It is also noteworthy that since the tragic Peelkhana massacre of commanding army officers in BDR rebellion last February, the investigations have been dragging on, preventing normalisation and reorganisation of our border forces. The BDR outposts have remained unarmed and uneasy. Scantily armed patrols are naturally dispirited, and commanding officers are yet to be hearty with the men. In the disarray, our northern and western borders have remained insecure. USA and some other foreign governments, who are partners of Bangladesh in anti-terrorist strategy and tactics, have expressly voiced concerns that Bangladesh borders are now unguarded and unsafe, easing passage for terrorists and narcotics traffic as well as for criminal influx. One wonders whether the government had adequately considered the implications of withdrawing an army brigade from CHT, thereby rendering our unguarded eastern borders deficient in surveillance and unsafe as well.
   
   Indian 'hot pursuit'
   The government of India has increased anti-Maoist military operations to the west of our borders and anti-insurgency operations in the north and east of our borders against tribal unrest and separatism. Fugitives from these operations will naturally try to cross into our borders and endanger our own peace and security. In such circumstance, grounds may be created for Indian security men to intrude into our territory in "hot pursuit" of fugitives. Bangladesh must, as it did in the past, remain prepared to defend its territory against intrusion of any sort.

   This is particularly so as the Indian strategic establishment appear to be having difficulties in adjusting to changing geo-political order after the failure of Bush doctrine. Indian Prime Minister and External Affairs Minister appear clear in their minds that under the impact of global financial crisis and from the experience of global war on terror, geo-strategic balance of the world order has shifted somewhat necessitating US-China cooperation, and the sole superpower is not so keen at the moment to prop up Indian power explicitly for the containment of China. But other political leaders and leaders of opinion in India seem unnerved by the signs and unmoved in their positions. So it is that Dr. Manmohan Singh's signing of an Indo-Pakistan Joint Declaration at Sharm-el Sheikh NAM summit de-linking India-Pakistan peace talks from cross-border terrorism has created an uproar in Indian polity that has not subsided. Indian strategic establishment is also expressly unhappy with US-Secretary of State Hilary Clinton's visit, during which she spoke of "greening" the Indo-US strategic partnership with a plethora of non-military issues.

   Suddenly a section of the Indian strategic establishment appear to be dropping traditional restraint and opting for drastic steps to push out Chinese influence from its periphery. They are pro-active in Nepal, Bangladesh and Sri Lanka, and their propaganda machine has also been tuned accordingly. They go so far as to question the motives of Sheikh Hasina Government of Bangladesh as well, and conjure spectres of an Eastern sub-Himalayan geo-strategic anti-Indian Compact. To quote an Indian Analyst Vijay Sakhuja (China Brief, Volume 9, issue 15, dated July 23):

   "According to Munshi Faiz Ahmad, Bangladesh's ambassador to China, Bangladesh and China have enjoyed a "time-tested, all-weather friendship" (China Daily, March 26). During their meeting on the sidelines of the U.N. Conference on the World Financial and Economic crisis in June 2009, Chinese Foreign Minister Yang Jiechi assured his Bangladeshi counterpart Dipu Moni that it was China's policy to "strengthen and develop the relations of friendship and cooperation with Bangladesh." For her part, Moni said that "Bangladesh sees China as its close friend and cooperation partner" (Xinhua News Agency, June 26). .....

   Chinese leadership has consistently advised Bangladesh to pursue an independent foreign policy and encouraged it to move away from India's sphere of influence. ...... Some retired Indian army officers, they believe that Chinese leaders may have even given Bangladesh security assurances that Beijing would stand by Dhaka and help it defend its national sovereignty and territorial integrity should it be threatened by India.."
   
   'Chicken neck' threatened?
   Sakhuja goes on to suggest that fresh concern arises from India's vulnerability in the Siliguri corridor, often referred to as the 'chicken neck': "This 200 kilometers (km) long and 40 km wide corridor links mainland India by rail, road and air with its Northeast region, a part of which (90,000 sq km in Arunachal Pradesh) is claimed by China and is a significant source of tension for bilateral relations. At present, there is significant PLA deployment along the borders. To its north is Bhutan, and in the south is Bangladesh. The Siliguri corridor figures prominently in the Sino-Bangladesh friendship and the two sides, according to Indian military experts, have a sophisticated strategy to sever India from the Northeast region. It is also noted that 'China wants to get Tawang [an administrative district in the state of Arunachal Pradesh] to come closer to the Siliguri corridor' so that it can link up with Bangladesh from the north (Why Assam Bleeds, sify.com, November 10, 2008). ......

   Illegal migrants from Bangladesh and Indian insurgent groups such as the United Liberation Front of Asom (ULFA), who have safe heavens in Bangladesh, crisscross through porous borders that can act as catalysts for social disorder, unrest and insurgency in the corridor. According to one analyst, the ULFA leadership has shifted its base to China, and the investigations relating to the March 2004 offloading of a weapons consignment from China at Chittagong seaport revealed the complicity of government agencies (India, Bangladesh: Joint Task Force for Countering Militancy, sspconline.org, May 27, 2009)."

   Finally, Sakhuja links up Indian military disadvantage from Chinese presence in Pakistani and Sri Lankan ports and possible access to Chittagong port with Myanmar and Nepalese land routes open to Chinese access:
   "There are concerns that Bangladesh may offer Chittagong port for development to China, ostensibly for commercial purposes, but which could also be used for staging Chinese naval assets. This is to be expected and can be reasonably tied to the Chinese development of Gwadar port in Pakistan and Hambantota port in Sri Lanka.

   China and Bangladesh, along with Myanmar, have decided to build the 900 km Kunming Highway linking Chittagong with Kunming through Myanmar to facilitate greater trade [7]. This would not only overcome the long sea passage from the east coast of China through Singapore (for trans-shipment) to Bangladesh, but would also lower transport costs and add to the economy of Yunnan?province. This also fits well in their joint initiative of improving Chittagong port infrastructure that can now be put to dual use for merchant vessels and also for the navies of the two countries. ?

   The Chinese approach of systematically nurturing and promoting diplomatic linkages with Bangladesh provides it with a number of strategic advantages against India. Likewise, there are also several related strategic fallouts for Bangladesh. As far as China is concerned, it will be in a position to link its electronic listening systems at Coco Island in Myanmar and the staging/listening systems in Bangladesh and monitor Indian naval and missile activity. Given the wide disparities in the India-Bangladesh naval order of battle, Bangladesh would be under pressure to open its facilities to the PLA Navy as a countervailing force against the Indian Navy. (Thus) China-Bangladesh military cooperation has the potential to exacerbate regional tensions along the Himalayas and result in high-intensity competition."

   Clearly, there is desperation in current Indian strategic thinking, in the backdrop of which Bangladesh must remain cool and cautions. The unseemly hurry with which a parliamentary team led by Abdur Razzak MP was sent to Delhi to dance to the tune of Indian authorities over the highly controversial Tipaimukh Dam Project is seen as unnecessarily buckling under Delhi South Block's pressure by Sheikh Hasina's government. There was scope to delay the delegation on the genuine ground that Bangladesh needed time to examine the studies released last week on NEEPCO website by Indian authorities. Sheikh Hasina's government stands compromised by the Razzak delegation in the eyes of the people of Bangladesh as well as the people of northeast India who are gravely threatened by earthquake risks and environmental degradation sure to be caused by the Dam.

[ALOCHONA] Tiapaimukh & other Other Water Projects in Asia [1 Attachment]

[Attachment(s) from Robin Khundkar included below]

Dear Alochoks - I hope the chaps on Alochona who are so hot and bothered about Tipaimukh will read this to get some context. Why it is necessary to have a broad based opposition to such Mega dam projects. Same old BS of using the water issues to camouflage other worthless agendas such BNP/AL or pure muslim chest thumping will not work in stopping such projects, the quicker the Isha Khan's of the Bangladesh realize it the better for all of us.

 

I have zero hope that this will happen because it requires quite time and patience which the Isha Khan clique neither has nor the inclination to do so. But for their convenience I am attaching a PDF version.

THE GREAT HIMALAYAN WATERSHED

Agrarian Crisis, Mega-Dams and the Environment

KENNETH POMERANZ

http://www.newleftreview.org/?page=article&view=2788

 

Many thanks to the Asia-Pacific Journal: Japan Focus, with whom this essay is co-published.

 

Kenneth Pomeranz (born 1958) is a professor in the history department at the University of California, Irvine in the US. He received his Ph.D. from Yale University in 1988. Most of his research focuses on China and its economy.

 

 

Since we tend to take water for granted, it is almost always a bad sign when it is in the news; and lately there has been all too much water-related news from some of Asia's most populous nations. [*] The stories have ranged from the distressingly familiar—suicides of drought-hit Indian farmers—to the surprising: evidence that pressure from water in the reservoir behind the new Zipingpu dam may have triggered the massive Sichuan earthquake in May 2008, for example. [1] Meanwhile glaciers, which almost never used to make the news, are now generating plenty of worrisome headlines.

 

 

 

 

For almost half the world's population, water-related dreams and fears intersect in the Himalayas and on the Tibetan plateau. Other regions have their share of conflicting claims over water issues: Turkey, Syria and Iraq over the headwaters of the Tigris; Israel and its neighbours around the Jordan basin; the us and Mexico over the Colorado River; the riparian states of the Paraguay, the Parana or the Nile. But none combine the same scale of population, scarcity of rainfall, dependence on agriculture, scope for mega-dam projects and vulnerability to climate change as those at stake within the greater Himalayan region. Here, glaciers and annual snowmelts feed rivers serving just under half of the world's population, while the unequalled heights from which their waters descend could provide vast amounts of hydro-power. At the same time, both India and China face the grim reality that their economic and social achievements since the late 1940s—both 'planned' and 'market-based'—have depended on unsustainable rates of groundwater extraction; hundreds of millions of people now face devastating shortages.

 

In response, plans are moving forward to harness Himalayan waters through the largest series of construction projects in human history. Looked at individually, some of these carry enormous risks and, even if they work as planned, will hurt large numbers of people while helping others. Looked at collectively—as overlapping, sometimes contradictory demands on environments that will also feel some of the sharpest effects of global warming over the next several decades—their interactions will be extraordinarily complex and their possible implications are devastating. Since many of the agencies responsible for these projects are far from transparent, it is very difficult to keep track of the rapidly multiplying future scenarios. But some basic outlines do emerge if we start from China—for various reasons, the most dynamic actor in the story—and then survey the broad belt of lands that border it to the south.

 

Chinese shortages

Water has always been a problem in China, and effective control of it has been associated with both personal heroism and legitimate sovereignty for as far back as our records go—or perhaps even further, since the mythological sage-king Yu proved his right to rule by controlling floods. But water scarcity has perhaps been an even greater problem than excess, especially in the modern period. Surface and near-surface water per capita in China today is roughly a quarter of the global average, and worse yet, it is distributed very unevenly. The north and northwest, with about 380 million people, almost 30 per cent of the population, and over half the country's arable land, have about 7 per cent of its surface water, so per capita resources there are roughly 20–25 per cent of the average for China as a whole, and less than 6 per cent of the global average. [2] Northern waters also carry heavier sediment loads: most readings on southern rivers fall within eu maxima for drinking water, while some on the Wei, Yongding and the middle and lower Yellow Rivers are 25 to 50 times that level; water shortages are such that northern rivers also carry far more industrial pollutants per cubic meter, even though the South has far more industry. [3] Northern China has unusually violent seasonal fluctuations in water supply, too; both rainfall and river levels change much more over the course of the year than in Europe or the Americas. North China's year-to-year rainfall fluctuations are also well above average, although not as severe as those in north and northwest India. While the most famous of China's roughly 90,000 large and medium-sized dams are associated with hydro-power—about which more below—a great many exist mostly to store water during the peak flow of rivers for use at other times.

 

The People's Republic has made enormous efforts to address these problems and achieved impressive short-term successes, which are now extremely vulnerable. Irrigated acreage has more than tripled since 1950, mostly during the Maoist period, with the vast majority of those gains coming in the north and northwest. It was this, more than anything else, that turned the notorious 'land of famine' of the 1850–1950 period into a crucial grain-surplus area, and contributed mightily to improving per capita food supplies for a national population that has more than doubled since 1949. Irrigation made it possible for much of northern China to grow two crops a year for the first time in history, often by adding winter wheat, which needs a lot of water; and plentiful, reliable supplies of water were necessary to allow the use of new seed varieties and chemical fertilizers, which can otherwise burn the soil. And, of course, irrigation greatly reduced the problem of rain coming at the wrong time of year, or not at all. During the previous two centuries, farming in northern China had become steadily more precarious, in part because population growth had lowered the water table—early 20th-century maps show much smaller lakes than 150 years before, and there are many reports of wells needing to be re-drilled at great expense—and in part because the safety net the Qing had once provided fell apart. But beginning in the 1950s and—after the setbacks of the Great Leap Forward—especially in the 1960s, things turned around very impressively.

 

Much of that turnaround, however, relied on very widespread use of deep wells, employing gasoline or electrical power to bring up underground water from unprecedented depths. [4] Large-scale exploitation of China's northern groundwater began in the 1960s and peaked in the 1970s, at roughly ten times the annual extraction rates that prevailed during 1949–61; it has remained steady since about 1980 at roughly four times the 1949–61 level. [5] But this amount of water withdrawal is unsustainable. The North China water table has been dropping by roughly 4–6 feet per year for quite some time now, and by over 10 feet per year in many places; if this rate of extraction is maintained, the aquifers beneath the plain will be completely gone in 30–40 years, according to some estimates. [6] This is by no means a unique situation. In the United States, for instance, the Ogallala Aquifer—which lies beneath portions of western South Dakota, Nebraska, Kansas, Oklahoma and Texas, and eastern Wyoming, Colorado and New Mexico—is being depleted at roughly the same rate. Serious excess withdrawals began there in the 1950s, and as in China, turned areas previously marginal for farming—the land of the 1930s Dust Bowl—into a bread-basket. But while the 175,000 square miles served by the Ogallala Aquifer are home to less than 2 million people, the 125,000 square miles of the North China Plain are home to over 214 million, 80 per cent of them rural. [7] The 2008 North China drought—the worst since the late 1950s drought that exacerbated the Great Leap famines—focused global attention on the problem for a brief moment, but chronic water shortages, both in cities and in the countryside, have been a fact of life for years, and conflicts over scarce or polluted water have become common events. [8] So, what is to be done?

 

Efficiency?

One hears periodically about inefficient water use in the cities: the Chinese steel industry, for instance, consumes about twice as much water per ton produced as steel-makers in the most technologically advanced countries (though the Indian steel industry is considerably worse than China's on this score). [9] Leaky pipes and other infrastructure problems create considerable waste. But relatively speaking, industrial and urban residential losses are small potatoes; agriculture still uses at least 65 per cent of all water in China—though less, even in absolute terms, than 20 years ago—and has far worse efficiency rates. [10] The cities are certainly not the site of the greatest wastage in commercial terms: according to one estimate, a gallon of water sent from the countryside to Tianjin yields 60 times as much income in its new urban locale as it did in the countryside. [11] The best hope of moderating overall water demand is probably to keep per capita urban use from growing too much, and improve use-efficiency, even as the urban population expands. Certainly price increases—unless they are intolerably large—are unlikely to cause city dwellers to cut back much. Any significant reductions will have to come from the countryside. That process has begun, but it is unclear how far it can go without devastating social consequences.

 

A great deal of water is wasted in agriculture, in part because costs to farmers are kept artificially low; besides, since most rural communities have no way to market water to those who would pay more for it, 'waste' has very little short-run opportunity cost for them. [12] But it is worth noting here that 'waste' has different meanings depending on what time-frame one adopts. Irrigation water that does not reach the plants' roots, but seeps back into the soil, is wasted in the short term—it cannot be used for anything else that year; but in the long term, it can help recharge the local aquifer. On the other hand, polluted water that could be recycled if treated properly, but instead flows out to sea untreated, is 'waste' in both senses and thus represents a bigger problem. Chinese agriculture is not necessarily more wasteful with irrigation water than that of many other countries—and the deviations from market prices are no greater than in the supposedly market-driven United States—but its limited supplies make waste a much more pressing problem.

 

Technologies that would reduce water waste do exist, but many are so costly that farmers are unlikely to adopt them unless they are subsidized. Centre-pivot irrigation systems, for instance, can save a lot of water, but at roughly $35,000 each—almost 60 years' income for an average north China farmer—they make sense only for the largest farms; they are also poorly suited to the geometry of existing fields, and to the requirements of rice and some other crops. Drip irrigation, sometimes called micro-irrigation, is another technological fix that has been greeted enthusiastically by many analysts despite being relatively expensive. The idea is that water is moved through small plastic tubes directly to the plants' roots, so that much less of it is wasted; it has been a huge success in Israel, where it was first developed, and in various other water-scarce environments.

 

More recently, however, doubts have been raised about its benefits, in large part because of the ambiguity of 'waste' mentioned above. Since drip irrigation makes sure that a higher percentage of the water gets to the plants' roots, it will enable a fixed water source—for instance, an above-ground tank catching winter rains for use in the spring—to irrigate more crops than if the water were distributed through traditional ditches or less precisely targeted sprinklers. Alternatively, one could irrigate the same size of crop, and have some water to sell to other users. But where the water source is an underground aquifer, which can be overdrawn and permanently depleted, the benefits become less clear. In that situation, much of the water that seeps away through the bottom of ditches helps replenish the aquifer and is not necessarily 'wasted' from a long-term perspective. On the other hand, precisely because drip irrigation means that almost every gallon of water a farmer buys will help the crops in the current year, it is a 'better buy' for him than water run through a less 'efficient' system; he is therefore tempted to buy more of it.

 

Thus, drip irrigation may be good for maximizing immediate food output, while actually exacerbating longer-run water shortages in places like northern China—or, as we shall see, much of northern India and Pakistan—where overuse of groundwater is a big problem. This possibility is not merely a theoretical one; a recent study of drip irrigation in the Upper Rio Grande Valley, on both sides of the us–Mexico border, came to the conclusion that it increased water use in precisely this way. [13] In short, selectively implemented high-tech solutions may help in some ways, but they cannot provide a total answer to China's problems—even if all the funding for them could be found.

 

Ironically, low-tech water-efficiency solutions may have greater potential. It is almost impossible to get a clear sense of how much water could be saved by simple measures such as re-lining or covering irrigation ditches, fixing leaky pipes, and so on. The amounts are probably very big, given the low quality of much of the water infrastructure in China and elsewhere. But these measures also cost money; most farmers or rural communities are unlikely to invest in them without subsidies or greater incentives. More effective pollution control—some, though not all, of which is possible with fairly simple and relatively inexpensive technologies—could also help enormously; but here, too, there are serious incentive problems. Local officials generally have more to gain by protecting local factories and jobs than by conserving water; especially, of course, the water of people downstream.

 

More commercial pricing of irrigation water would help provide such incentives—but here there are serious social and political constraints. More expensive water would almost certainly mean decreased agricultural output. Of course, China has enough foreign currency to buy food abroad, but the government is reluctant to become more dependent on imports. Dearer water might be particularly bad for the many farmers who have been switching from grain production to fruit and vegetables—crops that it otherwise makes sense for China to produce more of, since they demand much more labour per acre than grain, and can produce relatively high incomes for people with small plots. And even if Beijing, and the rest of the world, were content to see Chinese demand for imported food rise significantly, there is the question of what would become of the farmers themselves in such a scenario. Their incomes already lag far behind those of other Chinese workers. Any significant rise in water prices would probably drive millions of marginal farmers to the wall, and greatly accelerate the already rapid rush of people to the cities. Consequently, further water savings in agriculture, though vital, potentially huge, and far less environmentally risky than large water-moving projects, are likely to come slowly and painfully.

 

Transfers

Under the circumstances, many officials see no alternative to technologically ambitious mega-projects: above all, the South-to-North Water Transfer Project. The idea behind this $65 billion plan—tossed around for decades before being officially green-lighted in 2001—is simple: to take water from the Yangzi and its tributaries and move it to North China, where water is much more scarce. But implementing the scheme is extraordinarily difficult, and the consequences of any one of several possible failures could be enormous. [14] If completed, the Transfer will be the largest construction project on earth. It would carry almost 45 billion cubic metres of water per year—roughly the average annual flow of the Yellow River. [15] It has three parts:

 

1) An Eastern Route Scheme, which would take water from the Lower Yangzi in Jiangsu province up to Tianjin, roughly following the route of the Ming-Qing Grand Canal, and, via a branch line, to the Shandong peninsula. This is technologically the simplest part of the project—though it still raises plenty of questions. Parts of it began operation in 2008; it is scheduled to be completed in 2010.

 

2) A Middle Route Scheme, running from near the Three Gorges Dam in Sichuan to Beijing. Work on this route has recently been suspended in response to environmental problems, which have proved to be more complicated than was originally foreseen, and to resistance to relocation by people in the path of the project. (There were large protests in March 2009 near Danjiangkou in Hubei, where over 300,000 people are scheduled to be moved. [16]) Still, the official projection is that water will be reaching Beijing through this route by 2014.

 

3) A Western Route Scheme that is really two routes, taking water from the Yalong Zangbo (Yarlung Tsangpo), Dadu, Tongtian and Jinsha Rivers—all of which flow into the Yangzi—across mountains and the Tibetan plateau, and directing it into the Yellow River, which would then carry it across North China. This is by far the most complex part of the project; work is currently scheduled to begin in 2010, but it would not be completed until 2050.

 

The Transfer carries uncertainties commensurate with its size and cost. Among other things, there is considerable uncertainty about how dirty the southern waters will be by the time they arrive in the north. Diversions on this scale change flow speeds, sedimentation rates and other important qualities in unpredictable ways, and the original plans have already been modified to add more treatment facilities than were originally thought necessary. Changes in water volume will also affect the ability of other rivers to scour their own beds—effects on the Han River, one of the Yangzi's largest tributaries, are a particular concern. Conveyance canals passing through poorly drained areas may also raise the water table, add excess salts to the soil—already a common problem in irrigated areas of North China—and increase salt-water intrusion rates in the Yangzi Delta. [17] For better or worse, we will begin learning about the effects of the Eastern Route soon, and probably about the Middle Route in just a few years.

 

But despite its long time horizon, it is the Western Route—along with other projects in China's far west—which is the big story. First of all, it offers the most dramatic potential rewards. The idea is that it will tap the enormous water resources of China's far southwest—Tibet alone has over 30 per cent of the prc's fresh-water supply, most of it coming from the annual snow and glacier melts in the Himalayas. These water resources are an aspect of the Tibet question one rarely hears about, but the many engineers in the ccp leadership, including Hu Jintao and Wen Jiabao, are very aware of it. Chinese citizens are increasingly conscious of it, too—advertisements for bottled Tibetan water now adorn the backs of train seats and other sites, offering an icon of primitive purity of a type long familiar to Western consumers. Hydro projects in this mountainous region can offer enormous yields in electricity, as well as in water supply. The amount of power that water can generate is directly proportional to how far it falls into the turbines: the Yangzi completes 90 per cent of its drop to sea level before it even enters China proper, and the Yellow River 80 per cent of its descent before it leaves Inner Mongolia. [18] In April 2009, the Chinese government announced plans for twenty additional hydro projects on the upper Yangzi and its tributaries; if completed, these would theoretically increase the already existing hydro-power capacity on the river, which includes the Three Gorges Dam, by 66 per cent. [19]

 

Yet the Western Route also poses by far the biggest complications—and not simply because the engineering challenges are the most complex and the solutions most untested. It is here, and in nearby Yunnan, that the needs of agrarian and industrial China collide most directly with the lives of Tibetans, Yi, Miao and other minority groups. It is here that the environmental risks of dam-building become major international issues, with enormous implications for the Mekong, Salween, Brahmaputra and other rivers upon which hundreds of millions of people in the Subcontinent and Southeast Asia rely. And it is here that major water projects—which always include many uncertainties—collide with what has always been an extraordinarily fragile environment, and one which now faces far more than the average amount of extra uncertainty from climate change. Tibet, home to by far the largest glaciers outside the two polar regions, is expected to warm at twice the average global rate during the 21st century. [20]

 

Dam-building in Tibet

Although the prc built plenty of dams between the 1950s and the mid-1980s, relatively few of them were in the far west. This may seem surprising given the concentration of hydro potential in that region, but makes sense in other terms. The need to maximize energy production was less urgently felt before the boom of the 1990s, and there was much less concern about relying on coal, which still provides 80 per cent of China's electricity. [21] Many of the dams were constructed by mobilizing large amounts of labour—especially off-season peasant labour—in place of scarce capital: it was a lot easier to deploy those workers close to home than to send them far away. The supporting infrastructure—roads, for example—and technology for dam-building in remote mountain locations were not available; the far reaches of the upper Yangzi were not even surveyed until the late 1970s. The central government was also more ambivalent about rapid development in the far west than it is today; leaders tended towards more paternalistic policies, avoiding radical cultural change, as offering the best formula for political stability there.

 

But in the last two decades all this has changed, leading to a sharp shift towards huge dam-building projects in Yunnan and, above all, Tibet. The technical capacities and supporting infrastructure needed for capital-intensive projects in these areas are now available. The pressure to increase domestic supplies of both energy and water has become intense. In addition, the regime has clearly decided that raising incomes in the far west is the best way to keep control and make use of those territories—even if the wrenching cultural changes, massive Han immigration and severe inequalities accompanying this development increase conflict in the short to medium term. For better or worse, the kind of paternalism previously apparent in western frontier policy—dating back to at least the Qing, though it has been gradually weakening for a long time—is now being decisively abandoned. Meanwhile, changes in the relationships between central government, provincial governments and private investors have helped create enormous opportunities to gain both power and profit through accelerated dam-building.

 

Plans to 'send western electricity east', with a particular focus on developing Yunnan hydro-power for booming Guangdong, date back to the 1980s; seasonal deliveries of power first arrived in 1993. From 2001, Guangdong officials began concluding deals for regular annual power purchases with the authorities in Yunnan. At the same time, officials in Beijing began vetoing plans for additional coal-fired power plants in Guangdong, which made hydro-power an absolute necessity for the rapidly growing Pearl River Delta. [22] It is not clear, at least not to me, exactly what the relationship is between provincial and central government power in this story. One can see wealthy Guangdong reaching out to secure its own energy supplies here; but complaints from Guangdong about Beijing preventing the construction of power plants in the province, and about power shortages when sufficient hydro-power failed to come online on time, suggest that new inter-provincial agreements may often be shotgun weddings imposed by the centre, for whom the opportunity to create these configurations offers a means of both maintaining leverage over coastal boom areas and of integrating peripheral regions more deeply into the Beijing vision of a national political economy.

 

More generally, what has been called the 'corporatizing' of the Chinese electrical power industry has created complex webs of public and private actors with strong interests in southwestern hydro development. [23] In 2002 the government-owned State Power Corporation of China was broken into five corporations, each with exclusive development rights over particular watersheds (a sixth, connected to the Three Gorges, is directly under the State Council). These corporations are state-owned, but have created partly-owned subsidiaries which can sell shares to private investors on the Shanghai, Hong Kong and New York stock exchanges, thus raising capital while retaining control. For investors, meanwhile, power-generation stocks provide a way to bet on the Chinese economy in general, without needing accurate information on the prospects for any particular manufacturers. These subsidiaries, in turn, have combined with other subsidiaries of the big five, or with companies established by provincial governments, to set up still other firms that undertake particular projects.

 

While this system allows dam-builders to take advantage of private capital markets and corporate organization, their links to the state remain crucial. Huaneng Power Group, which holds development rights for the Lancang/Upper Mekong, was until recently headed by Li Xiaopeng, son of former Premier Li Peng, a chief advocate of the Three Gorges project. (The younger Li, who like so many other Chinese leaders has a background in engineering, has now moved on to become Deputy Governor of Shanxi, with responsibility for industry and coal mining. [24]) In setting up a subsidiary, the parent company will often endow it with important assets—generators, transmission lines, development rights—in return for a large stake in the new business; since well-developed markets for these assets rarely exist, and the state-owned parent company does not face the same pressures to be profitable as the subsidiary, the prices at which they are transferred can easily be manipulated to lower the costs (and increase the profits) for the subsidiary and its investors. And since all these firms continue to do business with each other—sending power over another company's lines, for instance—there are many opportunities to transfer costs back and forth between entities that need to show a profit and those that do not, or which are less favoured by powerful actors. [25] Government connections also make it easier for these companies to avoid acknowledging—much less bearing—the full social and environmental costs of their work.

 

Last but not least, the large and sometimes unpredictable fluctuations in water volumes far upstream mean that the turbines will not always be fully utilized, so that the actual amount of power generated may be much less impressive than the enormous figures for 'installed capacity' listed for these projects; uncertainties which holders of development rights seeking either investment partners or permission to build have no incentive to highlight. [26] This does not mean, of course, that dams—including large ones—may not make economic and even environmental sense in some cases, given China's limited options. It does mean, however, that in a number of instances dams are almost certainly being built for political motives, or as a result of profit-seeking by those with government connections, where even a narrowly economic analysis would not justify them.

 

Even the water-engineering projects that will genuinely help millions in northern and eastern China—and perhaps others, if they serve to curb the country's carbon emissions and future food imports—have serious implications for people who live in the regions where they will be built. Tibetans and other ethnic minorities in the far southwest are likely to be the most affected. In May 2009, an unconfirmed report by the Tibetan government-in-exile stated that at least six Tibetan women were injured when security forces opened fire on them as they protested against a hydro project on the Tibet–Sichuan border. [27] One issue here is that of human tampering with lakes and rivers that Tibetans hold sacred, such as the large dam at Yamdrok Tso. [28] A massive dam—40,000 megawatts, or almost twice the capacity of Three Gorges—proposed at the great bend in the Yalong Zangbo would again wreak a dramatic transformation on a holy site, in order to create power and water supplies that would mostly go to far-away Han Chinese.

 

Meanwhile, the project poses serious risks for the traditional livelihoods of many people. Road-building and railway-building—particularly the Qinghai–Tibet highway and the railroad that runs near it, completed in 2006—seem to have substantially degraded the permafrost layer in adjacent areas; the permafrost, in turn, protects a series of underground lakes, so that damaging it is likely to exacerbate an already worrisome drying trend in the region. A Chinese surveying team recently reported that some of the sources of the Yangzi itself are drying up, and the area is turning to desert. Wetlands and grasslands that are important to the large numbers of livestock herders in Tibet have already shrunk quite significantly; this is likely to accelerate the process. Existing dams in Yunnan appear to be interfering with local fisheries, and new ones pose significant threats to China's greatest concentration of biodiversity. [29] Since much of this region is seismically active, the risk of an earthquake precipitating a catastrophic dam failure and sudden floods cannot be dismissed.

 

South of the mountains

Hundreds of millions of people further downstream also depend on rivers that start in the Himalayas, of course. States to China's south that also have ambitious plans to harness their waters are worried that Chinese initiatives may preempt their own current or future usage. The massive hydroelectric dam and water-diversion scheme on the great bend of the Yalong Zangbo River is a case in point. The 40,000 megawatt hydro project is itself a huge issue. But what matters more for people south of the Himalayas is that the plan not only calls for impounding huge amounts of water behind the dam, but for changing the direction in which the water flows beyond it—so that it would eventually feed into the South-to-North Transfer project. That water currently flows south into Assam to help form the Brahmaputra, which in turn joins the Ganges to form the world's largest river delta, supplying much of the water to a basin with over 300 million inhabitants. While India and Bangladesh have worried for some time that China might divert this river, Beijing has repeatedly denied any such intentions. But rumours persist that a diversion project is in fact underway, and Indian premier Manmohan Singh is said to have raised the question of river boundaries in his January 2008 visit to Beijing. The latest Chinese denial was issued by former water minister Wang Shucheng this May. [30]

 

In 1999, Wen Jiabao, then Vice-Premier, told a meeting of Chinese scientist and engineers that water scarcity threatened the 'very survival of the Chinese nation'. Water is indeed a matter of survival, but not just for China. Most of Asia's major rivers—the Yellow, the Yangzi, the Mekong, Salween, Irrawaddy, Brahmaputra, Ganges, Sutlej and Indus—draw on the glaciers and snowmelt of the Himalayas, and all of these except the Ganges have their source on the Chinese side of the border, in Tibet. In many cases, no international agreements exist for sharing these waters, or even exchanging data about them. There are urgent water problems throughout South and Southeast Asia, but their nature varies as one travels from west to east. Pakistan and much of northern India face grave shortages of water for agriculture and daily domestic use, as well as poor provision of rural power. For many people the latter problem intensifies the former, as it makes the operation of deep wells increasingly impractical; but in the longer run, easing the power deficit without solving the water-supply crisis will just intensify future shortages. By contrast, in most of Southeast Asia there is plenty of water, for now; but electricity is in short supply, and plans to alleviate that problem through hydro-power threaten delicate riverine ecosystems.

 

Pakistan may be more dependent on irrigation than any large nation on earth. Over half of the country receives less than 8 inches of rainfall per year; by way of comparison, Phoenix averages 8.4 inches; only 8 per cent of Pakistan gets over 20 inches—the amount that falls in Tel Aviv. Yet the country is predominantly agricultural, and almost 80 per cent of its farming requires irrigation. As recently as 1990, irrigation accounted for a stunning 96 per cent of water use. As much of the groundwater is brackish or badly polluted, people often rely on diversions from irrigation canals to get water for their daily needs. [31] Agriculture remains central to the economy, and there are even plans, backed by foreign investors, for a sharp increase in grain exports, mostly to the Middle East. [32] Efforts to improve irrigation efficiency are underway, but the government is also looking for ways to engineer large increases in supply.

 

Northern and northwestern India are not quite as dry as Pakistan, but nonetheless have millions of farmers, several arid regions and highly irregular, often inadequate rains. For India as a whole, the per capita water supply is about a quarter of the global average, as for China. Moreover, half the annual rainfall comes in 15 days, and 90 per cent of total river flow comes during four months. Yet India has built only a fifth of the water-storage capacity per capita that China has, and about 4 per cent of that of the us or Australia. Canals for surface irrigation were built in some areas under the British, and on a considerably larger scale after Independence; but many have been poorly maintained or only serve those with political influence. In northern and northwestern India, probably even more than in northern China, well-digging has been essential to enable farmers to survive. It has also underlain the 'green revolution' which has raised agricultural production enough to keep up with the enormous population growth of the last half-century; the high-yielding hybrid wheat, rice and cotton seeds on which this was based all requiring more water than older varieties. Groundwater now provides 70 per cent of India's irrigation needs, and close to 80 per cent of water for domestic use. [33]

 

This aggressive exploitation of groundwater is unsustainable. Well water is free to any farmer who can reach it by digging down on his land; the electricity to run the pumps is heavily subsidized, straining the budgets of many Indian states. [34] Even at low prices, however, energy costs have become a huge burden for many small farmers, as water levels drop and pumps must work harder; moreover, irregular electricity supplies, with frequent spikes and interruptions, can often ruin pumps, wreaking sudden devastation on unlucky farmers. The large inequalities in landholding within many Indian villages—much more pronounced than in rural China—are a further complication. Richer farmers have every reason to drill deeper wells, take more water from aquifers, and resell whatever they do not use themselves at high mark-ups to people without wells, for domestic use; indeed, this is often more profitable than using the water to raise crops. Other farmers then also need to dig deeper, in response; as a result a tube-well race has developed, depleting aquifers even faster. Suicides of farmers who cannot get enough water to continue planting have become common in recent years, including instances of protest by mass suicide. [35] Some of these protests have been aimed at state governments that have raised electricity prices too high for many farmers to manage, although the rates are still far below those charged to city dwellers. Some are also aimed at corporate users and polluters of water—Coca-Cola has been a popular target. [36]

Some are also aimed at corporate users and polluters of water—Coca-Cola has been a popular target. [36]

 

There is also increasing concern that water scarcity and pollution could create dangerous shortfalls in agricultural output, especially in the Indian state of Punjab—which produces the country's largest agricultural surpluses, including roughly half the wheat and rice procured by the central authorities to stabilize prices—and in neighbouring Pakistan. [37] The pollution, bad enough to cause large increases in birth defects and cancer, has many sources, including the legacy of years of intensive irrigation, fertilization and pesticide use. Salination and water-logging, which also increases the incidence of malaria, have been mounting problems in the Punjab since the introduction of year-round irrigation by the British at the end of the 19th century. [38] It is estimated that in East Punjab today, 50 per cent of groundwater is recycled water from irrigation canals; in West Punjab, 80 per cent. Near Karachi, where it reaches the sea, the Indus now often fills only a small fraction of its bed; fishing has disappeared, an invasion of sea-water is harming agriculture, and water for domestic use is desperately short. [39]

 

This crisis has been met with a proliferation of plans for new water projects. Though people are well aware that the unintended consequences of past projects have played a role in creating current difficulties, the prospect of losing the gains in agricultural output achieved through irrigation is terrifying, and possibilities for alleviating serious electricity shortages—which, among other things, inhibit manufacturing growth that could reduce reliance on agriculture—seem very tempting. And while many plans are driven by real needs, China is hardly the only country where political and economic interests create incentives to build mega-projects that are incomprehensible in terms of costs and benefits. In India, for instance, the central government's inability to enforce water-sharing agreements among the states has led some upstream states to build extra storage facilities, in order to hang onto water that is at least as badly needed downstream; meanwhile, some downstream states, despite desperate shortages, have balked at implementing water-saving measures that might weaken their claims to a larger allocation from rivers flowing through multiple states. And since only direct human employment of water counts as 'needs' for these allocations, any other uses—e.g. releasing water to help maintain estuarial ecosystems—count as 'waste' that might weaken future claims, and are thus discouraged. [40] (Water-sharing agreements between India and Pakistan have thus far been more consistently observed than have those among Indian states, despite decades of hostility between these countries.)

 

Unsurprisingly, the most ambitious new plans are for sites in the highest mountains. Pakistan, India, Bhutan and Nepal are all aiming to build huge dams in the Himalayas. Planned construction over the next decade totals 80,000 megawatts, compared to around 64,000 for the whole of Latin America; India alone plans to add a further 67,000 megawatts in the next decade. Like China, India exploited the hydro-power in its less mountainous areas first, and has only 11,000 megawatts of non-Himalayan potential left. Even excluding China, potential Himalayan capacity is a staggering 192,000 megawatts, almost half of it in India. [41] Meanwhile, India's 2001 census reported that 44 per cent of households had no access to electricity; the figure is about the same in Bhutan and closer to 60 per cent in Nepal. Interest in dam-building is just as intense in Pakistan, though there irrigation is a higher priority than electricity. However, the estimated cost of the projects planned for the next 10 years is roughly $90 billion, much of which remains unsecured. India has financing for slightly more than half of its planned dam construction through 2012, but much less for needs through 2017. Pakistan has recently turned to Chinese financing and technical expertise for its Diamer Bhasha dam, a $12.6 billion project which was announced in 2006, but had trouble attracting capital. There has also been some financial support from Middle Eastern sources and various international development banks. [42]

 

Meanwhile, other foreign-backed plans will place additional strains on Pakistan's water supply. Investors from various wealthy but arid Middle Eastern states have recently been making large purchases of farmland, both in Pakistan and elsewhere in Asia and Africa. (South Korea and China have also been doing this, though not, as far as I know, in Pakistan.) The Pakistani Minister of Investment, seeking to dispel any fear that local farmers will be displaced, has said that all the 6 million acres up for sale or lease to foreigners—equal to roughly 10 per cent of the country's cultivated acreage—is currently unused. [43] If true, this means that any water devoted to it will represent an addition to existing demand. Indeed, a recent story in the Economist noted that many of these land deals seem to be aimed above all at the water rights that go with the land; it quotes the chairman of Nestlé referring to them as 'the great water grab'. [44]

 

Interlinking India's rivers

Since India, like China, is currently mining groundwater to produce grain surpluses in some of its vast dry regions, it may be no surprise that it, too, is contemplating a major scheme for water diversion. The most ambitious part of its Interlinking of Rivers Project, the Himalayan section, would move water from the upper parts of the Ganges, Yamuna and Brahmaputra Rivers westward, ending in the Luni and Sabarmati Rivers in Rajasthan and Gujarat; Haryana and Punjab would also receive some of the water. The project's second—'Peninsular'—section would direct water to dry parts of Orissa and Tamil Nadu. And just as China seems to be retreating from its earlier assurances to India that it had no plans to divert water from the Yalong Zangbo–Brahmaputra, so this project suggests that India is hedging on its more formal promises to Bangladesh—including a written understanding of 1996—that no water would be diverted away from the Ganges above the barrage at Farakka, a few kilometers from the India–Bangladesh border. [45]

 

Some of the intermediate links would create shipping channels, and the project also aims to reduce seasonal flooding problems on the Yamuna, especially near Delhi. It is also supposed to generate 30,000 megawatts of net hydro-power—that is, power available for other uses after subtracting the energy needed for moving water. The main purpose, however, would be to provide large amounts of additional irrigation water, mostly in western India; official plans claim it could increase the total irrigated area by as much as 35 million hectares. [46] Official estimates for the cost of the total project, with 260 links between rivers, run at $120 billion, which would make it even bigger than China's planned river diversions. Based on subsequent comments by members of the task force that drafted the plan, one study has suggested a revised price tag of $200 billion. [47]

 

Plans for the project have been shrouded in a degree of secrecy unusual for India—even more so, it appears, than with China's river diversion projects. It is hard to get an estimate of the number of people likely to be displaced, though two scholars put the number as high as 5.5 million. [48] Parts of the plan that have been revealed have been sharply criticized on a number of grounds, and it is unclear what will end up being built. Aside from posing several technological and ecological questions about specific aspects of the projects, both domestic critics and a World Bank study have noted that the water transfers being contemplated are only politically feasible if enforceable legal agreements can be reached on allocating the waters and compensating the 'donors'; such accords have generally not fared well in India. There is also a widespread consensus that more water conservancy money needs to go into improving maintenance of existing facilities, rather than further construction. One scholar largely supportive of the Interlinking of Rivers Project estimates that net water availability would be increased just as much by a 20 per cent improvement in water-use efficiency (although he points to other benefits, including hydro-power, and favours doing both). [49] Some opponents, on the other hand, have suggested that the project would so deplete resources for other water-works that the latter might have to be privatized to raise cash, at considerable risk to poorer customers.

 

Environmental risks

Before considering some of the wider environmental risks associated with these water projects, it is worth noting that in the case of large dams, environmental uncertainties represent considerable financial risks for the dam-builders themselves. Such dams have huge construction costs, but very modest operating expenses once they are finished; thus they can become big cash cows once they are generating power—especially if, as seems likely in this part of the world, demand for electricity continues to rise. Profitability is therefore dependent on how long they continue generating power after completion. That period can be cut short by many factors, of which sedimentation may be the most common. Sanmenxia dam on the middle Yellow River, completed in 1962, is a particularly notorious example—not only because it failed quickly and expensively, but because many of the problems had been predicted. (The project went ahead anyway, in part it seems because, after the withdrawal of Soviet technical experts, China wanted to prove that it could build such a dam without outside help. [50]) Because interest must be paid on the construction costs, profitability is also affected by how much time elapses before its revenue starts to come on-stream. Mega-projects that take a long time to complete are thus especially vulnerable, economically speaking, to any shortfall in power generation.

 

Three factors, at least, could make the lives of these new projects shorter than anticipated. First, the Himalayas are comparatively young mountains with high rates of erosion, and their upper reaches have relatively little vegetation to hold soil in place—a situation exacerbated by deforestation in recent decades. This tends to make for high sediment burdens in rivers descending from the Himalayas. A 1986 study found that almost 40 per cent of the small hydro-dams built in Tibet since 1949 had become defunct or unusable by being silted up; similar problems have developed on a number of Pakistani dams, which have lost their capacity for seasonal water storage and irrigation, as well as power generation. [51] Ironically, this loss of storage capacity has become an argument for building more dams. Second, any errors in predicting future river flow can have dramatic effects on the durability of a dam, sharply reducing profitability. Long-run data on flow fluctuation are not available for many of the Himalayan rivers, and the Chinese government has not been very forthcoming about the figures it has assembled. But there are reasons, mostly connected with climate change, to think that the future may be drier than the last few decades, especially in the western Himalayas (though there are also some reasons to believe the opposite). And it becomes exponentially harder to model future river flows when a great many large projects are being planned on the same set of rivers and tributaries. Several analysts of India's Interlinking of Rivers have questioned whether the Brahmaputra basin—a critical water source for this project—can be meaningfully considered to have a water 'surplus' even now; the likelihood (in their view) of a major Chinese diversion upstream and of glacial retreat due to global warming make the idea that any water is available to be transferred extremely dubious. [52]

 

A World Bank study of India's water future argues that the Himalayas offer one of the world's 'most benign environments' for dam-building. The basis of this estimate is simple: a calculation of people to be displaced and acreage to be submerged per megawatt generated. [53] Given the huge power potential in the denominators of these projects and the sparse population of many highland areas, these ratios are not surprising, and they deserve to be taken seriously. But they are by no means a complete measure of the costs and risks involved. Like all dams, those planned for the Indian Himalayas would submerge significant amounts of land, including forests and grazing areas important to a number of the remaining migratory people in the region. Several involve diverting rivers through underground tunnels which would create large dry regions, with serious impacts on local fisheries and farming. Moreover, the Himalayas represent a major—and fragile—concentration of biodiversity. Their rapid rise, from 500 metres to over 8,000 metres, creates a remarkable range of ecosystems within a relatively small space. Conservation International reports that, of an estimated 10,000 plant species in one Himalayan sub-region, over 3,100 are found nowhere else. [54] And here, too, as in Tibet and Yunnan, there are significant risks of earthquakes and glacial lake outbreak-floods.

 

Perhaps most surprising, it is no longer clear that large hydro-dams are even a consistently climate-friendly source of energy. While hydro-electricity can be a substitute for carbon-dioxide producing fossil fuels, the reservoirs behind big dams often include large amounts of rotting vegetable matter and thus are a significant source of methane—a much more potent greenhouse gas. (This is not an issue for 'run of the river' dams, which have no reservoirs; but these make up a very small percentage of big projects.) These methane emissions are larger in tropical and sub-tropical climates, where vegetation both grows and decays faster. A 2007 study suggested that methane from dam reservoirs actually accounted for 19 per cent of India's greenhouse-gas emissions, while hydro-power accounts for only 16 per cent of the country's electricity and less still of its total energy use. [55] These figures are still preliminary estimates; methane emissions may be lower than average for dams high in the Himalayas, which is not an area where plant matter grows or decays rapidly; and there may be ways to mitigate these effects, by capturing and burning the methane to generate more power. But they call into question the common assumption that, despite the environmental risks, large dams are a 'greener' energy source than most alternatives; the non-trivial greenhouse emissions involved in creating huge amounts of concrete and steel further complicate the picture.

 

Indochina

Further east, the plans are not quite as ambitious, but they still portend dramatic changes for millions of people. Those affecting the Salween River—known as the Nu in eastern Tibet and Yunnan—are shrouded in the greatest mystery, since for most of its length it is either in China or Burma, in places forming the Burmese-Thai border; neither regime welcomes publicity. Because the Salween still runs within steep mountain gorges for many miles after crossing into Burma, before dropping quite suddenly just before reaching its delta, there is enormous hydro potential here, and much less domestic demand. To date, the Salween has not been tapped very much for human use; it remains one of the few large free-flowing rivers left in Asia. A major dam on the Chinese side of the border was stopped in 2004 for environmental reasons, and work has recently been suspended again. However, there are now a number of dams planned or underway on the river, both in China—where the maximum programme calls for a 'staircase' of thirteen dams—and in Burma. [56] The expectation is that the power generated in Burma will be exported to Thailand, Vietnam and perhaps China.

 

A number of the Burmese projects are being built by Chinese companies and will be operated by them for several years after completion. Many are located in highland areas of Burma's Shan state, where the government has been trying for many years to gain fuller control over ethnic-minority populations. Activists have charged that the regime is taking advantage of the dam-building to further its political and military aims in the area by relocating the inhabitants. [57] Another planned dam would be built in what is essentially a war zone in the Karen minority region near the Burmese–Thai border. Much of the area is officially a wildlife sanctuary, but it has been heavily logged in recent years, particularly after Thailand banned logging on its side of the border; roads are now being built through it to facilitate dam construction—and state control. [58] Given the difficulty of visiting these areas, and the absence of information on which projects are at what stage, it is hard to guess at their likely social and environmental impact. And since the Salween watershed, with around 7 million people, is far less populated than the Mekong to its east, with around 70 million—not to mention the Ganges–Brahmaputra to the west, or the major Chinese rivers to the north—it has not had as much attention. Nonetheless, it raises the full range of complex issues and trade-offs, with fears about endangered species, fisheries and other resources upon which local people rely, forced relocations—and, according to some, forced labour—on one side, and pressures for development in an exceptionally poor country on the other.

 

The larger and more densely populated Mekong basin raises all these issues and more. Here both physical and political geography create an important divide more or less at the Chinese border. For one thing, the vast majority of the river's hydro-power potential is on the Chinese side. The river starts 5,500 metres up on the Tibet–Qinghai plateau, and is down to 500 metres above sea level when it leaves China. Its hydro potential within Yunnan alone almost equals its potential in Burma, Laos, Thailand, Cambodia and Vietnam combined—though the latter is far from trivial—despite the fact that Yunnan accounts for just a third of the river's descent within China. [59] Thus far, China has completed three hydro-dams on the Mekong, and has at least two more under construction; the complete plan appears to call for a cascade of at least eight, and perhaps as many as fifteen, large hydro-dams. [60]

 

Planning for the Lower Mekong began under a us- and un-backed Mekong River Committee in the 1950s; China and the Democratic Republic of (North) Vietnam were excluded, and Cambodian participation was also intermittent as its relations with the us fluctuated. While Lyndon Johnson, among others, spoke frequently of a major Lower Mekong Project modeled on the us Tennessee Valley Authority, no substantial work was done during the war years; what were apparently private us promises to help build Mekong dams as part of postwar reconstruction aid for Vietnam were never implemented either. Only in the late 1980s did a new Mekong River Commission emerge, with Vietnam and Cambodia now full members. [61] The Commission is relatively weak, however—neither China nor Burma are members—and the riparian states are mostly developing their own projects, often with partners from China, Japan or the us. So far China's main interest in the Lower Mekong has been in navigation. A whole series of projects have been carried out since 2000 to improve shipping, and traffic appears to have increased significantly in the last five years, along with road construction linking Yunnan province to Burma, Thailand and Laos. It is not clear just how important a shipping artery China hopes to develop along the Mekong. While one Chinese official spoke of Middle East oil shipments coming up the Mekong to China, should the us Navy block the Straits of Malacca in some future conflict, it seems implausible that such shipments could ever be large enough to matter much—although the idea of moving oil on the Mekong, with the risk of toxic spills, is a matter of concern to its farmers and fisher-people. [62]

 

While the hydro potential of the Lower Mekong may not match that of the Upper Mekong, it remains large—and all the more tempting when per capita income in the Greater Mekong region is estimated at one dollar a day. At least eleven large hydro-power dams are currently planned for the mainstream of the Mekong in Southeast Asia, mostly in Laos. [63] While there are widespread concerns that these dams could harm agriculture and fishing in the Lower Mekong—both of which are absolutely essential to the lives of its almost 70 million residents—regimes thinking in terms of industry, cities and 'modern' development may give electricity a higher priority. Meanwhile, the rather weak coordination among Lower Mekong states, and the absence of any real control on what China does, may well create a 'prisoner's dilemma' that encourages dam construction: if others are going to mess up the river's ecosystem anyway, why not at least get some electricity for one's own people out of it?

 

An obvious but important point here is that there is no 'ideal' river, divorced from any point of view or set of interests. For instance, if Chinese projections about the effects of the three existing dams and the two under construction on the Lancang–Upper Mekong are correct, the results would be a greater flow downstream in the dry season, and lesser in the wet season, with no change in overall annual flow; this would be good for navigation, for power generation, and perhaps for irrigation as well. [64] Projects designed to aid navigation also generally aim to balance out seasonal water flows. But even if this is true, dams on the Lancang could nonetheless have a serious impact on Lower Mekong fisheries, for at least two reasons. First, dams inevitably trap some nutrient-rich sediment that would otherwise flow through to the delta; this has been a problem with big dams elsewhere, appears already to be happening in parts of Yunnan affected by the first three Lancang dams, and is expected to happen on the Lower Mekong as well. Second, many species of fish respond to subtle variations in water flow to know when to migrate and spawn; changes in the seasonal timing of peak flow after the completion of the Three Gorges Dam, for instance, has had a devastating effect on four species of Yangzi River carp. The un estimates that 40 million people are active in Lower Mekong fisheries, and one report estimates that local fishing provides 80 per cent of the protein for people living in the region, as well as significant export revenues. Thai and Lao fishermen claim that the Chinese dams already in existence on the Upper Mekong have begun affecting their catches, while spokesmen for the dam-builders claim these projects have had no significant impact on the Lower Mekong. There are also claims that reduced water flow at some times of year has led to greater invasion of the delta by salt water, harming agriculture. [65]

 

Dams on the Middle and Lower Mekong could have other effects as well. They will interfere with fish migration, which is concentrated on the lower and middle (especially lower) parts of the river. Mitigating technologies to allow for fish passage have proved only partially effective even on low dams in North America and Europe, and the Mekong poses a vastly more challenging problem: the amount of fish biomass is perhaps 100 times what it is on the Columbia, where fish ladders have achieved some positive results, and the number of species several times greater. (The more diverse the species, the more various the times and places involved in migrations.) [66] The territory that the Middle and Lower Mekong passes through is also much less steep and even more biodiverse than the Upper Mekong—and being lower and more tropical, would probably have higher methane emissions from any reservoirs. In numerous ways, then, downstream dams on the Mekong may be more dangerous than upstream ones, and they would be far more expensive per megawatt generated. But their benefits would accrue mostly to people in the same countries that will suffer their probable harms—and that might be all that matters to planners thinking in terms of national interests.

 

Unilateralism?

However, while everybody is looking to dam the rivers descending from the Himalayas, China's position is unique. It is not only that most of the rivers in question start on China's side of the border, so that Beijing's claims cannot be pre-empted by actions further upstream. A second crucial difference is that the prc alone, of all the countries involved, can finance any project it chooses without recourse to international lenders. While the World Bank, Asian Development Bank and big private banks are not among the world's most ardent environmentalists, they have—either for their own reasons or because of pressures from third parties—refused to support some particularly controversial projects. China's domestic dam-building industry is also increasingly technically sophisticated, and is now exporting its engineering know-how in this area. Thus, the only constraints Chinese dam-building faces are those generated within the country, and these are often—though not always—quite weak. Late in January 2009, Jiang Gaoming of the Chinese Academy of Sciences released a sobering piece about how accelerating the construction of dams in China's southwest—part of the prc's ambitious stimulus package to fight the global recession—is worsening the already considerable environmental and social risks involved, with some projects beginning before any Environmental Impact Assessments have been completed. [67] Protests against Three Gorges by some leading scientists and engineers did not stop that project. [68] It remains to be seen whether they will have more effect in the future.

 

In short, the damage to China's neighbours from this approach to its water and energy needs could be severe—and the potential to raise political tensions is commensurate. Previous water diversion projects affecting the source of the Mekong have already drawn protests from Vietnam; and, as noted above, a project on the Nu, suspended in the face of significant domestic and foreign opposition in 2004 and then restarted, has recently been halted again by order of Wen Jiabao. But some projects now underway or being contemplated have considerably larger implications, both for the Chinese and for foreigners. The diversion of the Yalong Zangbo—if that is indeed on the agenda—would have the largest implications of all. If the waters could arrive in North China safely and relatively unpolluted—by no means sure—having generated considerable power along the way, the relief for China's seriously strained hydro-ecology would be considerable. On the other hand, the impact on eastern India and Bangladesh, with a combined population even larger than North China's, could be devastating. The potential for such a project to create conflicts between China and India—and to exacerbate existing conflicts over shared waterways between India and Bangladesh—is clear.

 

Climate change

Evidence is meanwhile mounting that, thanks to climate change, the water supplies all these projects seek to tap are less dependable than one might hope. A 2008 report published in Geophysical Research Letters noted that recent samples taken from Himalayan glaciers were missing two markers that are usually easy to find, reflecting open-air nuclear tests in 1951–52 and 1962–63. The reason: the glacier apparently had lost any ice built up since the mid-1940s, melting not just from the edges but from the top as well. [69] And since the Inter-Governmental Panel on Climate Change estimates that the Himalayan highlands will warm at about twice the average global rate over the next century, there is every reason to think the situation will get worse. One estimate suggests that a third of Himalayan glaciers will disappear by 2050, and two thirds by 2100. [70] Current models predict that this will happen much faster in the western than the eastern Himalayas; the situation for Pakistan and northwest India is thus particularly grim, with an initial windfall period of increased flows to be followed by a devastating loss of water in the already declining Indus, Sutlej and other rivers. [71] If that scenario is right, then even if all the engineering challenges of the South-to-North Water Transfer can be solved—and even if we ignore the costs to other users of these waters—the resulting benefits might prove short-lived.

 

Climate change poses other problems as well. Among the most serious are glacial lake 'outburst' floods. As glaciers in high-altitude regions melt, they can form large lakes behind natural dams of ice and rock. These are somewhat like the temporary lakes that formed behind dams of debris after the Sichuan earthquake last May, except that some of the 'wall' is ice. Such lakes are dangerous because they can burst through their barriers at any moment, creating devastating flash-floods downstream. (This was why Chinese soldiers dynamited the walls of Sichuan lakes, before they got any bigger.) Floods of this kind could easily overwhelm man-made dams downstream, causing a chain reaction of failure. Bhutan has identified 2,600 such lakes within its borders, including 25 at high risk of bursting out. [72] Meanwhile, though projections of likely changes in the monsoon due to global warming vary significantly, most suggest that South Asia will see fewer days of rain per year but a larger number of 'extreme precipitation events'—raising the need for water storage, but also increasing the risk of catastrophic failure should a large dam be built without sufficient allowances for these variations.

 

China is not, of course, the only country to try solving its water problems at the expense of its neighbours. I am writing this in southern California, where far more people live than could ever have been accommodated without diverting Colorado River water that once flowed to Mexico—some of which, by treaty, should still be doing so. And it would be foolish to rule out large projects in addressing the serious water and energy shortages facing hundreds of millions of people throughout this enormous region. But it seems increasingly clear that, even in a best-case scenario, such projects cannot solve all the problems they are meant to address—and they are likely to worsen many others.

 

Averting major disasters will require choosing carefully among the projects proposed, and coordinating efforts across national borders, to a much greater extent than is the case today. At least in the long run, technologies such as wind and solar seem much better bets to provide genuinely clean and affordable power; how to find badly needed palliatives for the immediate future without locking in reliance on less satisfactory technologies is a very difficult question. Above all, surviving the looming water crises probably rests much less on mega-projects and more on the implementation of an endless series of small-scale, unglamorous and sometimes painful conservation measures: fixing pipes and lining ditches; making factories treat water so that it can be reused; selective implementation of more efficient irrigation technologies; building some smaller dams; accepting greater reliance on imported food, and thus higher food prices elsewhere in the world; and continuing to create huge numbers of new non-farm jobs—without straining either the environment or the social fabric to breaking point.

[2] Such numbers vary depending on definitions of regions and ways of measuring water supply, but not enough to affect the general conclusions. Here I define 'north and northwest China' to include the provinces of Hebei, Shandong, Shanxi, Shaanxi, Henan and Gansu, plus Beijing and Tianjin municipalities; my figures are derived from Charles Greer, 'Chinese Water Management Strategies in the Yellow River Basin', PhD dissertation, University of Texas at Austin, 1975, p. 96. For comparison see: Olli Varis and Pertti Vakkilainen, 'China's Eight Challenges to Water Resources Management', Geomorphology 41, 2001, p. 94, which defines the North China Plain as containing 34 per cent of China's population, 39 per cent of its arable land and 6 per cent of its river run-off; us Embassy in China, 'South–North Water Transfer Ready to Start Work', Beijing Environment, Science and Technology Update, 16 November 2001, p. 2, describes a larger North, containing 44 per cent of the population, 60 per cent of its arable land, and 15 per cent of its water; James Nickum, 'The Status of the South to North Water Transfer Plans in China', Occasional Papers: Topical Background Research for the hdr, gives estimates for the Huang-Huai-Hai plain of 33 per cent of population, 40 per cent of farmland and 8 per cent of water supply. The map labeled 'Water Resources Distribution in China' in Pan Jiazheng (Chinese National Committee on Large Dams), ed., Large Dams in China: History, Achievements, Prospects, Beijing 1987, makes the regional disparities look even larger. Mark Elvin, 'Water in China's Past and Present: Cooperation and Competition', Nouveaux Mondes 12, 2003, pp. 117–20, improves on some of these numbers by incorporating estimates for groundwater as well as surface water resources, but the basic regional distinctions remain of similar magnitude. His total 'north' would include 46 per cent of China's population, with just below 15 per cent of all available water resources, and thus about 20 per cent of the per capita supplies.
