Terrace farming is a type of farming that was developed first by the Inca people. This method of farming uses “steps”, called Andenes that are built into the side of a mountain or hill.

On each anden, various crops are planted, and when it rains, instead of washing away all of the nutrients in the soil, the nutrients are carried down to the next level.
