Hydropower Projects on Drichu (Yangtze), Zachu (Mekong) and Gyalmo Ngulchu (Salween)

Tibetans proudly sing of their land as "the Land of Snows, the source of great rivers." Indeed, Tibet is widely regarded as “Asia’s Water Tower.” This blog post highlights hydropower projects (HPPs) on three of the major rivers that flow from Tibet: the Yangtze, the Salween and the Mekong. The Yangtze River originates in Tibet as “Drichu” and flows into China, supporting one of the most densely populated watersheds in the world. The Salween River, known as “Gyalmo Ngulchu” in Tibet, supports one of the most biodiverse watersheds of South Asia, mainly in Yunnan Province, Burma (Myanmar) and Thailand. And the Mekong River, known as Zachu in Tibet, flows from Tibet through six countries: China, Thailand, Burma, Cambodia, Laos and Vietnam. What goes on in the sources of these great rivers should concern not only Tibetans but also all citizens of the world.

The map below highlights 81 HPPs on the upper reaches of Yangtze, Mekong and Salween rivers. There are many more, especially smaller projects on the many tributaries of these rivers, which are not included in the map. We have only indicated HPPs that are relatively large, on the main stream and confirmed by two or more reliable sources. Unlike HPPs on the Yellow River and in the eastern edges of the Tibetan Plateau, most of the HPPs on these three rivers have not reached power generation stage yet. The completed projects are mostly smaller HPPs. The larger projects are either under construction (Gangtuo, Boluo, and Lawa) or in the construction ‘pipeline’ as “Under Active Consideration” or “Proposed.” It makes sense to build smaller ones first, which can help supply energy and infrastructure for construction of bigger projects.

Why is China building so many dams on these rivers? To answer this question, it is important to ask who makes the decision and benefits, and what are the larger (political, economic and historical) contexts under which these water development projects are being implemented. An important slice of this puzzle concerns China's Water Industrial Complex. Other contextual answers include China’s project of promoting rapid economic development in Tibet under the Go West! or Western Development Campaign. Energy needed for major mining, infra-structure construction and urban development projects under the Western Development Campaign will be supplied by these HPPs. Many of these HPPs will eventually be connected to larger (“Ultra-high voltage”) power transmission lines to supply energy to prosperous Chinese cities in the East.

China also plans to divert Tibet’s rivers. The Western Route of the South to North Water Transfer Project , which is slated to begin construction in 2010, is one such project. A detailed report published by the Ministry of Water Resources in 1995 reveals plans to build at least three very large dams on the upper reaches of Yangtze River. We have indicated one of these three dams, the 302 meter tall Tongjia dam, with a separate color for three reasons: details may have changed since 1995; the dam is not a HPP; and to keep the project under public scrutiny.

Since these HPPs are Chinese projects, we have used their Chinese names. Although a lot of work has gone into this map, including feedback from various experts, it is not final. The data shown in the map should be seen as our current knowledge, arrived at after research and consulting others, what the current situation is. We will be improving on this, so we seek your feedback, to produce a better and more formal report publication in the future. Meanwhile, those interested in using this map are free to do so.

Sources and Methods
The information shared in this series of maps on hydropower projects on the Tibetan Plateau has been obtained from a variety of sources. These include: Probe International, International Rivers, HYDROCHINA, news reports from both inside and outside of China, Chinese government and state owned corporation websites, Google Earth, JPRS China technical reports, and a number of scholars and experts who reviewed our maps.

The map is a collaborative project, as have been the others in this series. While I take full responsibility for inaccuracies, the real credit of this amazing work goes to my research assistant and map maker, who must remain anonymous for good reasons. I would also like to thank the many experts who have made valuable contributions to these maps. Your contributions have resulted in a much better map than would have been produced otherwise.

Hydropower Project: Definition and Categories
A Hydropower Project consists of an electrical hydropower station and associated dams, tunnels, ancillary buildings, roads, and modifications to the surrounding environment.

For the purposes of this map, a hydropower project's status has four possible values: Built/Operational, Under Construction, Under Active Consideration, and Proposed. These categories are fuzzy in the sense there is some overlap and each category can cover a wide range of examples.

The term 'Built/Operational' includes HPPs that have started generating power but are not complete, those complete and operational, as well as those that have been operational but are currently non-functional. The first report of a generator becoming operational is sufficient for a project to be assigned this status.

'Under Construction' indicates that work is proceeding on the ground though not necessarily that the river has been blocked or diverted. Ideally we would be able to have a 'Site Preparation' Status which would indicate that preparatory work is occurring at the site, but this is not possible without more detailed information than is typically available to us.

'Under Active Consideration' indicates that according to current data the project is being considered for construction, which may include exploratory work at the site, but is mainly intended to include design and other work not necessarily involving modifications of the site.

'Proposed' includes those HPPs which have been discussed but for which we have no information suggesting that they are currently under consideration.

'On Hold' indicates either that a project is being reviewed by Beijing, or that it has been reviewed and the government has decided not to allow it to go ahead.

Capacity is given in Megawatts. This should be understood to be the planned maximum rated power generation capacity of the generators of a HPP when it is completed. While every effort has been made to assure their accuracy, these figures are often given somewhat different values in different sources.

The positions of the HPPs shown on the map are approximate. A professional map should be used for accurate geographic information.

This map is the third in the series of maps of HPPs on the Tibetan Plateau. See here and in the here for HPPs on northern and eastern parts of the Tibetan Plateau and stay tuned for HPPs on the Brahmaputra River.

Wen Jiabao intervenes in Salween Dam Project Again!

The Chinese Premier Wen Jiabao has personally intervened in the construction of dams on the Salween River, once again, "calling for more careful environmental assessment and prudence before going ahead with the plan," according to the South China Morning Post. This intervention will halt the project for some time, as it happened earlier when the Premier first intervened in 2004. I am pleased to hear this news, but I wonder why he is intervening again.




China's official news agency Xinhua has quoted Foreign Ministry spokesman Ma Zhaoxu today saying that the "Chinese government attaches great importance to the utilization and protection of transnational rivers inside Chinese territory." Yeah right. Isn't the Mekong an international river?

The reasons provided by SCMP are far more believable: "Mr Wen ordered a halt to work on the Liuku hydropower station last month, telling authorities not to resume the plan until its impact on the ecology and local communities was fully understood." These are the same reasons provided in 2004. Chinese environmental activists campaigning to save the Salween River have been working very hard to keep the Premier's office apprised of these concerns and the state of construction on the ground. The real credit thus goes to the dedicated and well-coordinated work of these environmental activists.


Before I go further on this topic, I want to quickly bring up this notion of "two undammed rivers of China". This Times article quotes an activist saying that the Salween "is one of only two rivers in China that have not yet been dammed." I think the activist is assuming Yarlung Tsangpo (Brahmaputra) to be the other undimmed river. Chinese officials have made statements in the past that there are no dams on the main stream of the Brahmaputra River. This is misleading because China is building a 510 MW hydro project on the mainstream of the Brahmaputra river, about 140 km southeast from Lhasa, between Zangs-Ri (Sangri) and rGya-Tsha (Jiacha) counties.

Coming back to the work of environmental activists, one may wonder how they are able to campaign so successfully in a country like China where public works undertaken by powerful bureaucracies such as the Ministry of Water Resources, the Ministry of Machine Building and the Ministry of Construction are notorious for their lack of social and environmental concerns, as well as their use of state power to silence criticisms. How did a project in a remote location (in Yunnan Province and on the Salween River) attract sympathetic attention of national leaders? Where were these activists during the construction of the Three Gorges Project, the world's biggest dam?

The Three Gorges Dam is (probably) the most controversial construction projects undertaken by the PRC -- more than a million people were relocated to make way for the dam and its reservoir . Its construction began in 1994, directly under the supervision of the then Premier Li Peng. There are countless stories of corruption and mistreatment of relocatees and protestors. Dai Qing's work is a prominent example. Opposition to the project was not tolerated because the project was closely tied to the legitimacy of the Communist Party (by invoking, for example, Mao Zedong's support for the project) and the economic interests of key party leaders (e.g., China's power sector has been described as the "fiefdom of Li Peng family"). For more information on the dam, visit www.probeinternational.org and www.internationalrivers.org . In many ways, the sacrifices of the victims and activists of the Three Gorges Project paved the way for a new generation of critical environmentalists in China.

By early 2000, China had a critical mass of environmental activists and journalists who were beginning to form an informal alliance to check on China's dam construction madness. China has half of the world's large dams and it has been building more than one large dam per day since the inception of the country as PRC in 1949. The trend continues to this day. The only difference is that the size and the scale of these projects are getting bigger. In June 2003, a group of academics, journalists and civil society leaders gathered for a conference at the Chinese Academy of Social Sciences in Beijing to discuss the implications of irresponsible dam construction in the country. The conference was in fact the first of its kind in China.

The participants of the conference discussed many dam projects, including several that were planned on the Eastern and South-Eastern fringes of the Tibetan Plateau such as the Tiger Leaping Gorge dam, the Yeti Lake dam, and the Salween dams. It was informally decided among the activists that they will focus their campaign on the Salween Dams and the Tiger Leaping Gorge project. Unlike environmental activism in the West where campaigns often criticize the government, Chinese activists must work with the government. Their goal is to assist the government, specifically the State Environmental Protection Agency, in implementing its extensive environmental laws related to construction of development projects. And they had identified a perfect tool, the new Environmental Impact Assessment Law that was passed in 2003. The standards and specificities of regulations in the new EIA law are considered to be world class. The broader campaign strategy was to focus on saving the Salween River as a World Heritage Site.

Thus an unprecedented network of activists, journalists, ordinary citizens and government officials began a campaign, mainly of public education of the cultural and ecological heritage on the Nu Jiang or Salween River. On the ground public education work was spearheaded by veteran environmental activists like Wang Yongchen and Yu Xiaogang. Their campaign measures were remarkable because not only were these supportive of China's laws but these also had a kind of ripple effect of activism. Their innovative activities include sight-seeing and rafting tours in collaboration with local residents for officials, journalists and concerned citizens, and photo exhibitions in public places like the main post office in Beijing! This wonderful video provides an insight into the kinds of issues that have been advocated by these activists.



Not surprisingly this amazing campaign became famous. International media, governments, research think tanks, UN bodies, and not to mention ordinary Chinese people took notice. The campaigners also provided direct briefings to the office of national leaders. Thus in 2004, Premier Wen Jiabao intervened in the project and called for proper environmental assessment of the project.

A fresh round of environmental impact assessment was conducted and the review panel decided in 2005 that only four of the 13 proposed dams were allowable. The nine dams that were rejected by the review panel includes Songta Dam, planned in a location inhabited by ethnic Tibetans. The government has refused to disclose the EIA study. The study was classified as a "state secret" because of transboundary (international) implications of the project.

Then I read a report some time ago, which I am unable to locate right now, that preparation work for the construction of Salween Dams is going on covertly. This is alluded to the in the video above, expressing concern for the start of construction work for Liuku Dam, the first and the smallest of the four dams approved. Thus, the news about Wen Jiabao's intervention came as a delightful surprise.
