The Yangtze River

Podcast Transcript

Positioned inside the nation of China is the world’s third-longest river, the Yangtze.

The Yangtze River has been one of many defining geographical options in China because the daybreak of historical past. It had a big function in cultivating Chinese language civilization, and its flooding has been chargeable for a number of the best disasters on the planet.

Controlling the ability of the river has resulted within the building of the world’s largest dam.

Study extra concerning the Yangtze River, one of many nice rivers of the world, on this episode of All the pieces In every single place Day by day.

Every of the foremost rivers on the planet has a unique story. There are some rivers, just like the Nile and the Tigris and Euphrates, which have very deep histories and had been basic within the rise of the civilizations on their banks.

There are different rivers, just like the Rhine and the Mississippi, which don’t have fairly the identical historic credentials however are extraordinarily essential economically.

The Yangtze River checks each packing containers. It has deep historic significance, and it stays one of the vital essential financial rivers on the planet at the moment.

Earlier than I get into the historical past and significance of the river, I ought to clarify a number of the geographical info of the river.

The Yangtze is the world’s third-largest river by size, behind solely the Nile and the Amazon, and it’s the fifth or sixth-largest river on the planet by way of whole discharge quantity, relying on the way you outline it and the season.

Additionally it is the longest river on the planet, which is totally in a single nation, and the longest river within the Eurasian landmass.

The river begins within the Tibetan Plateau and winds 6,300 kilometers or roughly 3,915 miles to the Pacific Ocean, close to Shanghai.

The Yangtze River basin is the center of China, overlaying a full one-fifth of the realm of the nation and one-third of the inhabitants. The Yangtze Delta alone, close to Shanghai, is chargeable for a fifth of the Chinese language financial system.

The identify Yangtze is definitely not the identify of the river in Mandarin. The phrase ‘Yangtze’ is definitely an anglicization of the French time period for the river. In Chinese language, it is named Cháng Ji?ng, which merely means “lengthy river.”

The river flows roughly from west to east, and it has historically served because the dividing line between northern and southern China, much like how the Mississippi divides the USA between east and west.

The river might be roughly divided into three sections: the higher, center, and decrease Yangtze.

The higher Yangtze begins within the Tanggula Mountains on the Qinghai-Tibetean Plateau and flows eastward by the Qinghai, Tibet, and Yunnan provinces. This stretch of the river is thought for its deep gorges and valleys.

The center Yangtze flows by the center of China. That is essentially the most developed and economically essential part of the river. It flows by the provinces of Sichuan, Chongqing, Hubei, Hunan, and Jiangxi, and it’s house to a lot of China’s largest cities, together with Chongqing, Wuhan, and the previous imperial capital of Nanjing. The Yangtze Basin is sometimes called the “breadbasket of China” because of its fertile farmlands.

The center Yangtze can also be the situation of the Three Gorges. It’s a collection of three gorges which, for a lot of historical past, served as a restrict for navigation on the river.

The decrease Yangtze constitutes the Yangtze River delta, which is roughly outlined from Nanjing to the ocean.

Proof of people alongside the Yangtze goes again a very long time. The primary archeological proof of human exercise dates again 27,000 years within the Three Gorges space.

Regardless of the essential function that the Yangtze has performed all through Chinese language historical past, what we consider as Chinese language tradition and civilization at the moment didn’t truly originate alongside the Yangtze. It originated alongside the Yellow River to the north.

About 7,000 years in the past, the decrease Yangtze turned a significant inhabitants middle with individuals often called the Yue. The Yue had very completely different cultural practices than the individuals in northern China, together with dying their tooth black and heavy tattooing.

After the defeat of Yue by the Qing Dynasty, they started to undertake extra of the cultural practices of the north.

After the consolidation of China, the significance of the Yangtze solely elevated. Irrigation techniques had been put in place throughout the Han Dynasty, and by the Track Dynasty, the Yangtze had develop into the wealthiest area in China.

Along with being agriculturally productive, the Yangtze was additionally a significant transportation hall, permitting items to be transported from the ocean all the way in which into the inside of China. It was a part of the various routes which compromised the Silk Street.

The significance of the Yangtze was amplified with the development of the Chinese language Grand Canal. Whereas Nanjing was the capital of China for a number of durations in Chinese language historical past, so was Beijing. The Grand Canal linked Beijing with the Yangtze River.

The Grand Canal might be value an episode of its personal in some unspecified time in the future sooner or later, however it’s the longest synthetic waterway on the planet. Building started on it within the 4th century BC, and building continued for hundreds of years. The overall size of the canal is roughly 1,100 miles or 1,800 kilometers.

As productive and fertile because the Yangtze River valley was, there was an issue. Flooding.

The intensive irrigation system, which was constructed over the centuries, did mitigate a lot of the flooding on the Yangtze, nevertheless it didn’t remove it. Often, flooding could be really devastating.

The river’s worst flood, and what was most likely the worst flood in world historical past, passed off alongside the Yangtze in 1931.

China skilled a extreme drought from 1928 to 1930. The winter of 1930-31 noticed unusually heavy snowfall within the Tibetan plateau.

Because the snow soften began within the spring, it coincided with extraordinarily robust spring rains.

By June, low-lying areas alongside the Yangtze had been already underwater.

The spring rains had been simply the beginning of a particularly lengthy wet season, which additionally noticed an uncommon 9 typhoons make landfall that 12 months.

The consequence was a flooding of not simply the Yangtze however most of the tributaries of the river in your complete drainage basin.

On prime of the acute rainfall, the dykes and levees on the Yangtze had been in poor form and had been unable to carry again the flood waters.

The consequence was the flooding of 180,000 sq. kilometers or 69,000 sq. miles of land. That is the equal of many of the island of Nice Britain or the states of New York, New Jersey, and Connecticut mixed.

Farm fields had been flooded, which compounded the issue of the drought from the earlier years.

The variety of fatalities from the flooding has been estimated to be as excessive as 4,000,000 individuals. The 1931 flood ranks not simply because the worst flood in historical past by way of whole dying toll but in addition because the worst pure catastrophe of any kind in historical past.

The Yangtze skilled extreme flooding in 1954 and once more in 1998. The flooding wasn’t frequent, however when it occurred, it could possibly be devastating.

The thought of controlling flooding on the Yangtze goes again to the early twentieth century. The founding father of the Republic of China, Physician Solar Yat Sen, on whom I’ve completed a earlier episode, proposed the creation of a dam on the Yangtze.

Along with controlling flooding, such a dam would additionally present an infinite quantity of electrical energy for China.

An preliminary survey was performed close to the Three Gorges part of the river in 1932, instantly after the 1931 flooding. In 1944, throughout the struggle, United States engineers created a plan, and so they even introduced Chinese language engineers again to the USA for coaching, however the plan by no means got here to fruition because of the Nationalists shedding the Chinese language Civil Warfare.

The Communists beneath Mao Zedong supported the thought of a Yangtze dam, however they had been unable to make any progress on it. The Nice Leap Ahead and the Cultural Revolution left China ready the place they had been unable to undertake such a big venture.

Whereas a dam on the Yangtze would management flooding and produce an infinite quantity {of electrical} energy, there have been severe environmental and cultural issues about what a dam would do.

The lake created by a dam would destroy many communities, cultural websites, and effectively as plant and animal species that inhabited the river.

Within the Eighties, with Mao behind them, the Chinese language authorities ignored many of the issues and determined to proceed with the dam. The dam venture was authorised on the 1992 session of the Nationwide Folks’s Congress, with 67% help.

I point out the vote solely as a result of this was a particularly low proportion of help for a physique that usually voted on issues unanimously.

Building started in 1994, and the dam was anticipated to be accomplished in 2006, however the venture wasn’t accomplished till 2012, nearly eighteen years after building started.

Dubbed the Three Gorges Dam, it’s the largest dam on the planet. It’s 2.3 kilometers or 1.5 miles lengthy. The rattling used 27.2 million cubic meters of cement and sufficient metal to construct 63 Eiffel Towers.

The quantity of electrical energy generated by the dam is astonishing. When all of its generators are functioning, it will probably produce 22,500 MW of energy. It will probably produce greater than twice the quantity of electrical energy because the world’s subsequent largest rattling.

It was estimated that when the dam produced a thousand terawatt hours of electrical energy, it will pay for the development of the venture. It was estimated that it will take ten years to recoup the funding as soon as the dam was accomplished.

The dam produced a thousand terawatt hours of energy inside its first 12 months.

Along with the dam, there have been additionally a number of locks constructed to facilitate transportation on the river. Earlier than the dam’s building, the Three Gorges was very troublesome and harmful to navigate.

The brand new locks considerably lowered the price of transportation on the river and elevated the quantity of freight transported on the river by nearly an order of magnitude.

Previous to the development of the dam, 18.0 million tonnes of cargo handed by the Three Gorges space per 12 months. In 2022, there have been over 159.65 million tons.

The Yangtze has a whole lot of issues because of the fast progress of China over the past a number of many years. The Yangtze River sends extra plastic air pollution into the ocean than some other river on the planet by a large margin.

90% of all of the plastic within the ocean comes from simply ten rivers, and the Yangtze has extra plastic waste than the opposite 9 rivers within the prime 10 mixed.

The excellent news is that steps are being taken to scale back the quantity of plastic air pollution within the river, which might be the one greatest factor that could possibly be completed on Earth to scale back general plastic air pollution.

The Yangtze has been one of the vital essential rivers on the planet for 1000’s of years and it stays so at the moment, being a supply of transportation, electrical energy, and irrigation for a lot of China.

Regardless of the future might maintain, it’s fairly probably that the Yangtze will stay central to China for hundreds of years to come back.
