Which benefit derived specifically by pre-Columbian cultures implementing chinampa cultivation?

💡 Explanation

When pre-Columbian cultures cultivated chinampas, they created raised beds utilizing nutrient-rich mud from lake bottoms, leading to expanded arable land in wetland environments. Therefore, increased land capacity resulted rather than disease reduction, water retention or soil fertility alone, requiring alternate mechanisms.
