Which risk increases when Aztec chinampa agriculture experiences prolonged drought conditions?

💡 Explanation

When chinampas experience drought, increased evaporation leads to capillary action which deposits dissolved salts from the groundwater on the surface, causing soil salinization because of reduced flushing. Therefore increased soil salinization results, rather than less runoff, fewer pests, or better filtration which depend on sufficient water.
