In 2002, Yu submitted a report to the central government on the social impact of the Manwan Dam on the Lancang (Mekong) River, which prompted the government to give the local community $8.7 million in additional resettlement funds to mitigate the negative social impact of the dam.
In the past, dam-building plans were simply dictated by government officials, but today, thanks to the advocacy efforts of Yu and others, the Chinese government now includes a social impact assessment in the decision-making process for all proposed major development projects.
While Yu’s work has illustrated dams’ potential negative impact on communities, huge dam projects still are being proposed. As China’s economy grows, pressure increases to supply more power by building hydroelectric power plants on the country’s river system.
In 2003, the Yunnan provincial government announced plans to construct 13 new dams on the Nu River, one of the Three Parallel Rivers—the Nu, Jinsha (Yangtze) and Lancang. The Three Parallel Rivers and surrounding watersheds are a World Heritage Site, the epicenter of Chinese biodiversity containing virgin forests, 6,000 species of plants, and 79 rare or endangered animal species.
The dams would forcibly displace 50,000 people, indirectly affect the livelihoods of millions living downstream in China, Burma, and Thailand, and negatively affect the flora and fauna in the surrounding areas. Yet, development continues, despite the lack of river management plans, public input and participation by affected villagers.
Yu used the story of Lashi Lake and Manwan Dam to educate villagers in the Three Parallel Rivers area, taking them by bus to dam-affected communities on the Lancang River. There, villagers saw men and women, their way of living wiped out by the dam, picking through garbage dumps for scrap to sell. Yu also worked with CCTV on a television program about the effect of dams that aired nationwide.
In 2004, Premier Wen Jiabao suspended plans for the dams on the Nu River, saying that more research and scientific analysis were needed. The project is still on hold, but the provincial government, intent on building the dams, has proposed a scaled-back version with four dams.
Yu is particularly interested in empowering local villagers in the dam decision-making process through workshops and training programs. In 2004, he took five village representatives to a United Nations symposium on dam issues in Beijing, where they met with high-level government officials, dam company CEOs, and experts on dam construction. Yu’s goal is for Chinese NGOs to advocate for the institutionalization, implementation, and practice of social impact assessments for the interests of communities that are threatened by dam construction.
“Having villager participation forever changed the history of the dam decision-making process,” Yu said about the experience. “In the past, affected peoples were silenced. They had no voice in what happened to them and had to accept decisions made by the government and dam companies.”
