Which ancient civilization is characterized by their agricultural practices in mountainous areas?

The Incas are known for their remarkable ability to cultivate crops in mountainous areas, particularly in the Andes mountains of South America. They developed advanced agricultural techniques, including terracing and irrigation systems, that allowed them to manage the steep and varied terrain effectively. This innovation was crucial for sustaining their population and supporting their society, which was one of the largest and most powerful in pre-Columbian America.

Their agriculture included staples such as potatoes and maize, and they also practiced advanced farming techniques like crop rotation and the use of various altitudes to grow different crops, which further maximized their agricultural output. This adaptation to the mountainous environment is a defining characteristic of Incan civilization and showcases their ingenuity in overcoming geographical challenges.

The other civilizations mentioned did not primarily focus on mountainous agricultural practices to the same extent as the Incas, which sets them apart in this context.
