What were Chinampas used for?
Likewise, why did Aztecs use Chinampas?
Chinampas were essentially artificial islands created for the crops. These islands then provided rich soil for crops with easy access to water. The farmers used channels between the islands to get to each area by canoe. Read more about this type of Aztec farming here.
Subsequently, question is, do people still use Chinampas? Most of the chinampas have been abandoned and filled in - they weren't used as much after the conquest. When the Spanish arrived, the chinampas covered nearly 9000 hectares. However, some remain in use today. Remnants of the canal system can be seen in Xochimilco.
Subsequently, one may also ask, where are Chinampas used today?
The modern-day Chinampas can be used on top of lakes, ponds, or any other fresh body of water. One application of this garden will be cattle ponds, the ponds that cattle ranchers use to provide drinking water for their cattle.
How did the Aztecs make floating gardens?
These floating gardens were a masterpiece of engineering. Each garden was 300 feet long by 30 feet wide. To make a garden, workers weaved sticks together to form a giant raft, and then then piled mud from the bottom of the lake on top of the raft to create a layer of soil three feet thick.
