Terrace farming was important to to the Inca civilization because it was a way to make farming a possibility on steep mountains. It also prevented soil erosion and conserved water throughout irrigation systems (Deng). Beyond just the use of it, the Incas' terrace farming really showed off their engineering skills. It was understood that they had a deep understanding of agriculture, which is why they were able to sustain a vast empire for hundreds of years (Alconini). 

Terrace farming was not originally invented by the Inca people. Instead, they adopted the idea and made a significant improvement. The Incas used stone walls to support their terraces, created irrigation systems to supply the water evenly, and used layers of soil and gravel to prevent flooding (Ronda pg.1).

Terrace farming had an extremely significant impact on the Inca civilization. It allowed them to grow crops and supply food for the community, even in the difficult conditions of the Andean Mountains. Terrace farming helped support a large population and made it, so civilization could expand further (Alconini).

Believe it or not, but the practice of terrace farming is still in use today. Many farms in hillside regions still use it to grow and produce their crops. It is very productive and supplies people with the food they very much need. The use of these terraces is still a fantastic way to save water and soil, especially in places where the ground is steeper and there is a bigger risk of washing away (Bonsall).

This invention was historically important because it allowed the Inca civilization to survive, expand and maintain their empire. It provides them with the necessary food they need to work as a community and flourish greatly. By improving their agricultural production, the Incas were able to support themselves and their economy (Alconini).
