Which water management consequence resulted from extensive chinampa cultivation in the Basin of Mexico ca. 1500 AD?

💡 Explanation

When chinampa cultivation expanded, increased evaporation occurred because the raised beds presented a large surface area of water exposed to the air for transpiration, increasing local humidity. Therefore increased humidity resulted, rather than salinization, depletion, or nutrient runoff, which involve different chemical transport mechanisms and geographical contexts.
