Answer :
Final answer:
The Andean peoples influenced Inca agriculture primarily through the introduction of terrace farming, which allowed farming in steep terrains and helped prevent soil erosion. This agricultural innovation enabled the Incas to maximize productivity in the challenging Andean environment by creating flat plots of land for cultivation. Techniques such as advanced irrigation and the use of guano for fertilization further enhanced their agricultural success.
Explanation:
Influence of Andean Peoples on Inca Agriculture
The Andean peoples significantly influenced Inca agriculture, particularly through the introduction of terrace farming.
Farming in the steep topography of the Andes was challenging, and the innovation of creating terraces allowed the Incas to cultivate crops in areas that would otherwise be unsuitable for agriculture. These terraces functioned by forming steps along the mountain slopes, allowing for flat plots of land where soil could be tilled. This method also helped prevent soil erosion, ensuring the sustainability of agricultural practices in the highlands.
Furthermore, pre-Inca cultures like the Tiwanaku had already developed similar techniques over 3,000 years ago, which the Incas expanded upon. They utilized materials from their surroundings, incorporating advanced irrigation and fertilization techniques to enhance crop yields, including the transport of guano from distant coastal areas to fertilize their fields.
Conclusion
Overall, the adaptation and expansion of Andean agricultural techniques were vital for the Incas, enabling them to support a large population and develop a complex society.
