Before I did my googling and math, I couldn’t believe it but here it is: Shanghai has added as much land as 10 Manhattans over the past couple of decades. Here are some satellite images as witness:

The number of people living in Shanghai is not the only thing about the city that has increased dramatically since the 1980s. The amount of land available to its residents has grown as well. By building seawalls just off the coast to capture outflowing sediment, and by using dredging equipment that sucks up and moves large volumes of sand, Shanghai has added well over 580 square kilometers (220 square miles) of land to its shorelines since 1985.

Even though this many have survived the dramatic urbanization and land reclamation over the past few decades, they have most likely shrunk a great deal. With many new neighborhoods on low-lying lands that used to be lakes, the battle against floods this year is a particularly difficult one.

Shahu Lake (or literally translated as sandy lake) used to be the second largest lake after the East Lake in Wuhan City. Since 2000, due to the encroaching real estate development and urbanization, the lake has been divided by a road and surrounded by high-rise buildings (above). Read More
