Introduction:
The Three Gorges Project, situated in the
densely populated Yangtze Valley, is the world’s
largest resettlement project. According to
official figures, the dam has submerged 13
cities, 140 towns and 1,350 villages. When the
project was launched, the authorities promised
to provide replacement land to farmers and
new jobs to the urban population. Yet arable
land is scarce in China, and the government had
to stop resettling farmers on steep hills to check
erosion. In addition, when resettlement began,
many state-owned enterprises were closing
down rather than creating new jobs.Farmers
did not receive compensation for their lands
because they did not officially own them, and
the compensation they received for their
houses was often not sufficient to pay for their
new homes. Some cities overcame the shock of
resettlement and restarted their economy.
Others became dilapidated a few years after
they were built.
Objective of building
dam:
The Three Gorges Project has completely
changedthe ecosystem of the Yangtze River. It
has interrupted fish migration and altered the
river’s chemical balance, temperature and
velocity. The mighty river has been turned into
a stagnant pool with a limited ability to clean
itself, and local boat owners are fishing garbage
off the surface.The dam has most likely driven
the famous Chinese river dolphin to extinction.
Populations of the Chinese sturgeon, river
sturgeon and Chinese paddlefish have been
decimated; all are now considered
endangered.Commercial fisheries in the Yangtze
and off the river’s mouth in the East China Sea
declined sharply after the dam was closed.
Measures taken to
counter the problems:
Prime Minister Wen Jiabao reported in 2007
that over the years, dam building had displaced
no less than 23 million people in China. Many of
these people remain impoverished. As the
Three Gorges Project was being completed, the
negative impacts of dam building became ever
more evident to China’s government and
society.After the turn of the century, non-
governmental organizations began to champion
environmental protection,and farmers stood up
against projects that did not respect their
interests. In 2005, more than 100,000 people
protested the construction of the Pubugou Dam
in Sichuan Province. As a result of domestic
pressure and the newly inscribed.Three Parallel
Rivers World Heritage Site, Prime Minister Wen
Jiabao suspended the construction of several
dams on the Nu River in 2004 and again in
2009. Neither President Hu Jintao nor the Prime
Minister attended the inauguration of the Three
Gorges Project. In May 2011, China’s highest
state body warned that the project has “caused
some urgent problems in terms of
environmental protection, the
prevention of geological hazards and the
welfare of the relocated communities.” Despite
the experience with the Three Gorges Project,
China has resolved to increase its hydropower
capacity by as much as 120 GW – the
equivalent of seven Three Gorges Dams – by
2015 in order to meet its climate change
targets.
Economical uses:
China is still using energy relatively inefficiently.
Theefficiency of Chinese electrical motors for
example, which consume more than half of the
country’s power, is 10-30% lower than
international standards. Successive
governments have made great strides to
improve energy efficiency, and energy demand
has grown more slowly than the economy
throughout the 1980s and 90s. Pressure to
maximize economic growth reversed this
positive trend between 2001 and 2005.
Improving energy efficiency during this period
could have obliterated the need for the Three
Gorges Project – and at a lower cost. “It would
have been cheaper, cleaner and more
productive for China to have invested in energy
efficiency [than in new power plants],”
