The Cool Highlands
The creation of flat land on mountain slopes for the purpose of farming.

The people living in Tierra Fría wear warm woolen clothes to protect themselves from the chilly temperatures.
In Tierra Fría, farmers have had to adapt their farming ways according to the cool highland environment of this section of the Andes. They have discovered that crops such as potatoes, wheat, barley, corn, apples, and pears grow the best in this climate. These are the main foods the people living in Tierra Fría eat. But through adapting to this environment, the people have come up with the process of vertical trade. This type of trade allows people who live in one elevation zone to have access to food grown in a different elevation zone. Through vertical trade, the people living in the Andes are able to receive a better variety of foods as well as a more balanced diet.
Two of the main activities that take place in Tierra Fría are terracing and vertical trade. The exact definition of terracing is the creation of flat areas on mountain slopes for the purpose of farming. To do this, farmers cut fields out of steep hillsides, build walls on the slopes, and fill them in with soil in order to create flat land that is used for planting. This method goes back many centuries. The Incas had used terracing to create their great civilization. The exact definition of vertical trade is the trading of crops between lowland and highland areas. This is a way for the people who inhabit the Andes to receive more of a variety of foods and a better balanced diet. Through this way of trading, they are able to receive foods that they otherwise would not have any access to.
