Which environmental risk was most likely reduced by chinampa construction in the Valley of Mexico?

💡 Explanation

Chinampas, or 'floating gardens,' reduced soil erosion because their raised beds were isolated from seasonal floodwaters by canals, which act as a barrier. Therefore, reduced soil erosion resulted, rather than insect outbreaks, nutrient depletion, or salt accumulation, which stem from different agricultural or environmental stressors.
