How is Mexico sinking?
It’s the result of a geological phenomenon called subsidence, which usually happens when too much water is drawn from underground, and the land above begins to compact. According to new modeling by the two researchers and their colleagues, parts of the city are sinking as much as 20 inches a year.
Do any floating gardens still exist?
The floating gardens (chinampas) of Xochimilco, near Mexico City, formerly supplied crops to the Aztec capital of Tenochtitlán and are still utilized for the cultivation of flowers and vegetables.

What do most Mexicans call Mexico City?
For the past two centuries, the city has been known as “DF” from its official name of Mexico Distrito Federal, or Federal District. But now the city of nearly nine million will be known as Ciudad de Mexico, or CDMX. That is the Spanish version of what the city is already called by English speakers: Mexico City.
Why is the ground beneath Mexico City subsiding?
As water extraction drove groundwater deeper underground, the 100-meter-thick, salty, clay-rich lake bed was left high and dry. Its very fine mineral grains have since been steadily repacking themselves more tightly, causing the ground to shrink and subside.
How long will it take for Mexico City to sink?
Researchers estimate that it will take 150 years for this foundation to become completely compact, and for the city to stop sinking by as much as 20” a year.
When did Mexico City start sinking?
Scientists first noticed Mexico City was sinking in the early 1900s, at a rate of roughly 8 centimeters a year. By 1958, that had jumped to 29 centimeters a year, which led to a decision to cap the amount of water that could be brought up from wells in the city center.
Is Xochimilco safe?

How did Aztecs grow their food?
To grow all this food, the Aztecs used two main farming methods: the chinampas and terracing. Chinampas were essentially man-made islands, raised bed gardens on the surface of Lake Texcoco’s shallow waters.The chinampas farms were man-made plots of land built up from the sedimentation from the bottom of the lake.
