Which benefit did chinampa construction provide to Mesoamerican agriculture, specifically mitigating which risk?

💡 Explanation

Chinampas, artificial islands in shallow lake beds, facilitated intensive agriculture by the mechanism of constant nutrient resupply because of seasonal/annual flooding bringing nutrient-rich sediment. Therefore overcoming nutrient depletion due to intensive farming results, rather than frost damage, erosion or weed issues which are addressed by different agriculture mechanisms.
