How do people grow crops in the Andes?

In the Andes, people grow crops using traditional agricultural techniques adapted to the region's challenging terrain and climate. They often practice terracing, which involves creating flat areas on steep slopes to maximize arable land and reduce soil erosion. Additionally, they utilize diverse microclimates and altitude variations to cultivate a variety of crops, including potatoes, quinoa, and maize. Indigenous knowledge and practices, such as crop rotation and the use of native seeds, also play a vital role in sustaining agricultural productivity in this mountainous region.
