The Three Gorges Dam (TGD) is an enormous dam that has been built across the Yangtze River in China. It stands at a height of almost 200 metres and can hold almost 40 billion cubic metres of water! The Three Gorges Dam project is the biggest hydropower project that has ever been built in the history of mankind. This article will introduce you to some of the environmental changes that have been associated with the TGD project.
Increased Pollution
Electricity is needed to run the TGD, producing a formidable amount of pollution from the burning of coal – such as carbon dioxide. A study by Hodum carried out in 2007 concluded that a vast amount of untreated wastewater is dumped into the TGD on an annual basis. In fact, statistics for Chongqing already show a shocking annual untreated wastewater output of close to one billion tonnes. The Chinese government has announced government spending plans to combat pollution, though these plans have not yet come into effect.
Threats to Biodiversity
The Yangtze River Basin is an important part of China’s biodiversity, containing 36% of China’s known freshwater fish species. The building of the dam has resulted in a significant metamorphosis of the fishes’ environment. Drastic habitat transformation could well lead to changes in migration, feeding and spawning habits, completely changing China’s biodiversity outlook. Another concern is the possibility of rising counts of endangered fish species.
Increased Ecological Threat
The sediment load carrying patterns of the Yangtze River have also been affected by the TGD project. Specifically, since the completion of the project sediment loads have experienced a downward trend. A side-effect of this trend has been increased coastal erosion, changing the landscape of China.
The building of the dam could also increase the risk of geological disasters such as landslides and earthquakes in the future. These disasters can be difficult to predict and could swiftly damage the economy and socio-economic stability of China.
Flood Protection
One important design function of the TGD is to help control the flooding problem during the rainy season. In July 2012, the region experienced record-high flood water forces. The dam was successful in helping to soften the blow of the flood water, acting as a buffer. Lessened flooding damage could have a positive impact on the environment by lessening the burden on drainage and sewer systems and decreasing the chance of flood-related accidents.
Conclusion
Today’s article has focused on the environmental impact of the TGD project, and it is evident that there are both advantages and disadvantages of the project. The future successes – or failures – of the project will help us to make a judgement on whether the advantages outweigh the disadvantages. |
