Is The Inca Food System Sustainable?

Yes!

I would say that the Inca food production system was sustainable. I think this because they seem to have many advances that a lot of cultures didn't have in that period of time. They managed to work with their environment and overcome the many obstacles it brought. They built terraces to make growing crops on a steep hill easier. They also had canals to use as irrigation to make sure their plants where watered. They also always has a three to seven year surplus of food that was preserved using what they called as "chuno" which is the process of leaving food out such as potatoes in the cold night to freeze to later be sun dried. Overall because they had all of these successful advancements along with their surplus I would say this food production system was very sustainable.
