Which risk increased for Ur's city canals following deforestation during the Early Dynastic Period?

💡 Explanation

When deforestation occurred in the Mesopotamian highlands, soil erosion increased because of the reduced root structure, causing increased silt runoff into the canals. Therefore, canal blockage resulted, rather than decreased grain yields, flow rates, or pest infestations, which require other environmental conditions such as salt accumulation, drought, urban sanitation failures.
