This year’s rainy season and floods have wrecked havoc on the city of Wuhan, which was home to 127 lakes in its urban areas. Now the city has 38 lakes remaining. 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. Here below are a couple of examples viewed from space, thanks to Google Earth and those who care to find these images.

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

Really amazed by this MIT scientist/photographer who has taken this to an artistic level, documenting the dramatic changes over the landscapes of many Chinese cities. There are more on his site here.

Watch where urbanization sprawls in and around the U.S.’s capital between 1984 and 2010, via NASA Earth Observatory:

Any surface that water cannot pass through—for instance, rooftops, roads, parking lots, and sidewalks—is considered impervious.

The maps above show the extent of impervious surfaces in 1984 (top) and 2010. Areas with the greatest concentration of impervious surfaces are depicted with dark blue; areas with the lowest concentration of impervious surface areas are white.

Here’s a much more dramatic urbanization case study, China’s Pearl River Delta area, where you can see the rapid development of Guangzhou, Shenzhen, Dongguan between 1988 and 2014, also thanks to NASA Earth Observatory:
