Answer :
Terrace farming is a technique used to grow crops on steep slopes by building a series of leveled terraces into the hillside. This method of farming helps to prevent soil erosion, conserve water, and maximize arable land in areas with limited flat land.
What is terrace farming ?
The Incas, who lived in the Andes Mountains of South America, needed to use terrace farming due to the rugged terrain of their homeland. They constructed thousands of terraces, using stone walls to create level platforms that could support crops such as potatoes, maize, and quinoa. By using terrace farming, the Incas were able to cultivate crops at high altitudes and produce enough food to sustain their large population.
Terrace farming also allowed the Incas to adapt to the harsh climate and unpredictable weather conditions in the Andes, where they experienced frequent droughts and frost. By using terraces, they were able to irrigate their crops and protect them from frost damage.
Overall, terrace farming was a critical technique for the Incas to survive and thrive in their mountainous homeland.
