For Pre-Columbian chinampas, which hydrological outcome results from reduced dike maintenance?

💡 Explanation

Compromised dikes invite saltwater intrusion due to hydrostatic pressure differences; therefore, saline water degrades the island microclimate, rather than enhancing nutrient flows, limiting agricultural productivity because of osmotic imbalances created by increased soil salinity.
