Which outcome resulted when ancient Andean terrace farming interrupted natural watershed flow?

💡 Explanation

When terrace construction altered the drainage patterns, waterlogging in the lower terraces occurred because the subsurface water flow was impeded, causing salts to accumulate through capillary action. Therefore soil salinity increased, rather than decreased crop yields since terraces improve soil, downstream deposition which requires increased flow, or reduced biodiversity due to fragmentation
