The Yangtze River in China is the
third largest in the world. The Chinese call the river Chang Jiang, which means
“Long River." With more than 30 industrial cities along the coast, this
river provides about 70% of the inland water transportation. In addition to the
industrial cities, the river runs through more than 25% of the agricultural
farmlands and supports about a third of the population in the country, which
has great economic, cultural, and political importance to China.
The controversial Three Gorges
Project (TGP) had been proposed for three reasons: to produce more efficient
hydroelectric power (power generation) for the country; flood control; waterway
navigation purposes.
Although the great amount of
hydroelectric power produced would benefit the country, there are many
controversial issues about the TGP. By building a gigantic dam across the
Yangtze River, it would create significant impacts on the river itself and
affect the living people along the coast. With the TGP under way, there would
be a submergence of the local coastal cities. About one million innocent
civilians would be displaced to local inland urban cities. The integration of
the two populations would cause an over crowding and social disruption to the
local existing community. However, the main concerns of the TGP are the
negative environmental impacts that the project would create.
However, the environmental effects outweigh
the social impacts. The disruption of the environment and the ecosystem would
alter the natural capital of China. These environmental drawbacks include:
water pollution, fish migration, inundation, landslides, sedimentation, ground
water contamination, soil erosion, water loss of the "great lakes" of
China, ground water contamination of Shang Hai, eutrophication, and an outbreak
of water borne disease.
On the other hand, as 19 countries
would be affected by the TGP, this in turn would affect a total population of
14 million people. A possible worldwide impact, an "economic and social
disaster" would have to be taken into consideration. However, within the
general vicinity, resettlement of 727,000 people will have to take place due to
the submerging of towns and urban centers. The relocation of the population
would not only affect the people socially, but also economically in the end. In
addition to the submerging of towns and urban centers, historical sites (dating
back to 10,000 B.C.) will also be submerged. As for the economic concerns,
China would be drastically affected by the agricultural shifts. Vital farmlands
would be submerged and so will coal mines and metal mines worth millions of
dollars. With a decrease in land availability due to the submergence, the lack
of replenishment of land would affect the industry and the agriculture of the
country.
An analysis of how these impacts
would affect the society, environment, and the economic stability have to be
taken into consideration. However, if no isolation of a single benefit from the
TGP can be made, proposals would have to take place, which are about
alternative roots to fulfill the demand for energy (hydroelectric power), flood
control, and navigation within the water systems of China.
