Terrace farming is a key agricultural method in which region?

• A. The Andes (Inca)
• B. The Nile Valley
• C. The Amazon Basin
• D. The Tibetan Plateau

Answer: (A)

Terrace farming is a solution to steep, rugged terrain where flat fields don’t exist. By shaping the slope into stepped flat platforms and building retaining walls, people can control water, reduce soil erosion, and create stable planting surfaces. In the Andes, the Inca engineered vast networks of terraces, known for climbing the mountainsides and creating many microclimates. These andenes made it possible to grow staple crops like potatoes, maize, and quinoa at high elevations where the climate and thin soils would otherwise limit farming. That combination of engineering and high-altitude agriculture is why terraces are most famously associated with the Andean region.

Other regions depend on different farming patterns: the Nile Valley relies on floodplain irrigation from seasonal floods, the Amazon Basin on forest-supported shifting cultivation and dense jungle ecology, and the Tibetan Plateau uses local hillside cultivation but not to the same iconic, expansive scale seen in the Andes.
