Which outcome accelerated soil degradation in some pre-Columbian Andean terrace farming systems?

💡 Explanation

When irrigation water evaporates, salt deposition occurs because water salinity concentrates in the soil over time, leading to reduced fertility and crop yields. Therefore, salinization results, rather than overgrazing, monoculture, or deforestation which involve alternative land management challenges.
