Three Gorges Dam

The Three Gorges Dam is a massive hydroelectric dam on the Yangtze River in China. It is the world's largest power station in terms of installed capacity and plays a crucial role in flood control, electricity generation, and improving navigation. The dam has been a subject of controversy due to its environmental and social impacts, but it remains a significant feat of engineering.

    Chapter Five The Three Gorges Dam Revisited
         
    Approaching the Three Gorges.
    Passage contains an image
    W hen China celebrated fifty years of Communism on October 1, 1999, Premier Zhu Rongji proudly hailed the enormous achievements of the Chinese people, particularly the economic transformation undertaken during the previous twenty years. But the project that is meant to symbolize these achievements remains mired in controversy. Since it was first proposed by Sun Yatsen in 1919, the idea of damming the Three Gorges of the Yangtze River and constructing the world’s largest hydroelectric generation and water-control project has fascinated China’s leaders. Although the project had the personal endorsement of Mao Zedong and Deng Xiaoping, internal opposition was surprisingly strong and was silenced only during the crackdown on dissent after the 1989 Tiananmen protest. Meanwhile, international criticism—especially of the project’s far-reaching environmental impacts—rose to a fever pitch. The United States and Canadian governments and the World Bank and Asian Development Bank, which had showed initial interest in the project, quickly backed away. China went ahead anyway, determined to make the Three Gorges Dam the crowning success of its drive to modernize its economy. The first earth was moved in 1993, and by the end of 1997, two giant cofferdams enclosed the Yangtze River and construction of the dam itself had begun. Even die-hard opponents realized that nothing would stop the project, and the furor died down.
    Although other dams are bigger, Three Gorges will consume 27 million cubic meters of concrete, almost enough to pave over Washington, D.C. It will be capable of generating two-thirds more energy—84 billion kilowatt hours per year—than any other dam in the world. The dam will be 1.2 miles wide and 185 meters high. Behind it the water level will rise as high as 175 meters, submerging 10 percent of the Three Gorges, 13 cities, 140 towns, 360 villages, 1,300 known archaeological sites, and 62,000 acres of farms and orchards, and will create a reservoir 632 kilometers long. By its own admission, the government will have to resettle at least 1,133,800 people who presently live in the reservoir area below the 175-meter level. According to official 1997 estimates, it will cost US$24.4 billion. The dam is scheduled to enter into full operation in 2009, seventeen years after construction officially began.

    13Building a dam for China in the Three Gorges region, 1919–1971 Covell F. Meyskens
    In the early twentieth century, Chinese leaders began to contemplate building a large dam on the Yangzi River that would generate electricity, boost river transport, and end its history of floods. They paid particular attention to the Three Gorges region, where the river ended its descent from the Sichuan Basin into Hubei province’s Jianghan Plain. This chapter examines Chinese efforts to construct a dam near the Three Gorges between 1919 and 1971. It concentrates on this block of time, because the first dam proposal appeared in 1919, and the Gezhouba Dam became that place in 1971. Past scholarship has overlooked this period and focused on the building of the Three Gorges Dam (TGD) in the 1990s (Dai, 1998).
    I take a different tack and trace the Chinese government’s aspiration to make a TGD to a new understanding of technology’s power precipitated by Western imperialist pressures in the mid-nineteenth century. Prior to Western imperialism’s arrival, elites in China did not take the rapid expansion of technological power as a primary economic goal (Wong, 1997; Elvin, 1973). This changed when Western imperialists and their scion – Meiji Japan – used technological strength to assert influence over East Asia. In response, elites in China embraced the Western notion that technological self-strengthening was central to a country’s economy and that its territory was a repository of resources useful for industrialization (Halsey, 2015; Wu, 2015; Pietz, 2014).
    After laying this historical groundwork, the chapter highlights three defining features of Chinese efforts to erect the TGD. First, Chinese elites manifested a belief in the national benefits of technologically redesigning the environment of the entire Yangzi region. Second, Chinese leaders acted like nationalist elites in other late-developing countries and advocated using state power to advance industry (Gerschenkron, 1962: 5–30). Third, Chinese elites repeatedly sought out foreign assistance to offset domestic shortages of industrial capital. These three trends engendered two approaches to technology, or what Thomas Hughes (1983) calls technological styles, which reflected different understandings of how to use experts, labor, and capital.

    We, therefore, deal with them in the con-text of these larger developments. Four Modernizations and the Three Gorges Dam The adoption of the four modernizations policy in the 1970's led to a commitment to increase the country's GNP fourfold by the end of the century. Mid-1980's estimates indicated that this task would require that by the year 2000 China be able to generate 240 million kilowatts of elec-tricity. The Three Gorges Dam could at best contribute less than 15 mil-lion of these kilowatts. This urgent energy situation created strong in-332 Three Gorges Dam PROJECT centives to adopt policies that would provide maximum electrical generating capacity at minimum direct cost and with the shortest possi-ble lead time—that is, to build thermal plants rather than massive hy-droelectric facilities. Other considerations, though, diminish the allure of thermal plants. Thermal power poses troublesome environmental problems, especially given the high percentage of China's power generation that is fueled by coal. Major new thermal power facilities also require new rail construc-tion and other additional efforts that affect comparative cost calculations. On balance, the mid-1980's pressures to increase electrical output at the least short-term cost evidently weighed against start-up of construc-tion of the Three Gorges Dam. In the coal sector, as explained in Chapter Seven, similar pressures produced an increased emphasis on develop-ment of local coal facilities, even though over the long run greater in-vestment in major central mines would probably have been a wiser strat-egy. Quick payoffs for minimum investment appear, then, to have become the preferred way to meet the ambitious four modernizations goals. Although the four modernizations policy highlighted the critical im-portance of adding to electrical power generation capabilities, this did not necessarily make it more likely that a dam at the Three Gorges would be seen as a good investment strategy.

To international observers of resistance against mega dams, the Chinese peasantry may seem rather passive. China builds dams. It builds lots of them. Time after time the Chinese Government seems to encounter lit- tle resistance. Perhaps the most infamous of these constructions is the Three Gorges Project (TGP) on the Yangtze River. It is the world’s larg- est dam and it was built with seemingly minimal resistance from those it directly affected. The dam was and remains high profile. This megalith of engineering graced the pages of National Geographic in the late 1990s and it captured the attention of the world’s media, non-governmental organizations (NGOs), and international banks. It also attracted criticism within China and abroad. The contention drew tourists from all over the world on long journeys to say goodbye to a place they did not know. However, for all the outside attention there was another group of people, a large group, who had to move to make way for the project. Some of them resisted and it is their resistance that this chapter explores.

    For example, the Three Gorges Dam on the Yangtze River in China is more than five times the size of the Hoover Dam (U.S.), and will create a reservoir 600 km long to be used for hydro-power generation. Its construction required the loss of over a million people's homes and their mass relocation, the loss of many valuable archaeological and cultural sites, as well as significant eco-logical change. It is estimated that to date, 40-80 million people worldwide have been physically displaced from their homes as a result of dam construction.

The open valley at the dam site, with hard and complete granite as the bedrock, has provided the favorable topographical and geological conditions for dam construction. Its installed capacity is 18.20 GW and the annual average generation reaches 84.7 billion kWh, equivalent to that generated by combustion of 40 million tons of coal. The project also plays an important role in flood preven- tion and navigation improvement on the Yangtze River. Going through 70 years’ course from initial envisage through planning, investigation, design, verification and decision-making, the TGP was eventually left off ground via voting by the National People’s Congress in 1992. The huge scale of the project necessitates RMB 90.09 billion Yuan at 1993 price (equivalent to USD 15.74 billion based on the exchange rate in 1993), of which RMB 40 billion Yuan (equivalent to USD 6.99 billion) is used as compensation for the resettlement of reservoir residents, accounting for 44.4% of the total investment. The whole construction period lasts up to 17 years. Taking into account of price factor and interest rate change of banks during this long period, it was pre- dicted in 1994 that the total investment of the project would be RMB 203.9 billion Yuan (equivalent to USD 25 billion). The total population relocated reaches 1.13 million, and 12 new towns are to be rebuilt. Beginning from 1993, TGP has entered its implementation phase.

    In the 1980s numerous discussions took place about the dam project, and topics ranged from dam site selection and resettlement to technical issues. The project was in principle adopted by the State Council in 1984, and was expected to be included in Seventh Five-year plan (1986-1990). However, obstruction from Chongqing as well as economic recession hindered the approval of the dam project. Preparations for the project went nevertheless ahead, and feasibility studies were carried out by both Chinese and international experts. Apart from a few Chinese experts, the conclusion was positive and the reports recommended the construction of a dam in the Three Gorges. Nevertheless, opposition to the project became more vocal within China as the preparations for the dam project intensified. Two hundred and seventy representatives to the NPC opposed the project, and requested that the project be postponed until the next century. These protests resulted in the then vice premier Yao Yilin announcing that the decision on the project would be postponed until 1995. Nevertheless, after the student demonstrations were brutally ended on 4 June 1989, opposition against the project died down and preparations for the project continued in 1990. The floods in the summer of 1991 once again put the need for flood control in the Three Gorges area to the foreground. The project was finally approved by the NPC in 1992, with one-third of the representatives voting against or abstaining, signifying the great opposition to this project in China. The political significance of the Three Gorges project debate is that it was not only a debate about the technical issues for a dam project. It also gave a cloak of legitimacy for the bureaucracy itself as well as the scientific sphere to criticise the way decision-making in general is carried out in the PRC. The construction of the dam began in 1994, and is now in the second phase of the three-phase construction period. By the end of 2002, 645,200 people had been resettled.
