This is a time lapse of Shanghai, China from 1984 to 2016. Shanghai is located on the east coast in China, just south of the Yangtze River and the Huangpu River runs through it. According to Statista 2018, Shanghai’s population was around 7.1 million in 1985. In 2016, it grew to be about 24.61 million. Shanghai was the fastest growing large city and the largest city by population in the world. It’s growth rate was 10 percent a year for the last 20 years. This population is expected to keep growing. Reaching around an estimated 34.34 million by 2035.
With the rising population and increased threats of global warming, Shanghai is left vulnerable to extreme flooding. It has two coastlines, miles of canals, rivers, waterways, and shipping ports. This makes it one of the most vulnerable cities in the world for catastrophic flooding, according to a report done by a team of UK and Dutch scientists. Many factors play into why it is considered the most vulnerable city, such as population living close to the coastline, prevention, and recover time from floods. An estimated 17.5 million people could be impacted.
Measures have been taken by the government to try to prevent these catastrophic floods and divert the water somewhere else. It will be interesting to see how the city changes in the next 30 years.
