Which challenge arose using chinampas because dikes degraded?

💡 Explanation

Increased soil salinity results from dike failure in chinampas because a hydraulic gradient drives saltwater intrusion across the unprotected agricultural plots, causing salt accumulation; therefore, crop yields fall rather than enhanced disease resistance, respiration, or nutrient uptake, all outcomes reduced by hypersaline environments.
