Which risk increases when irrigating farmland using ancient Mesopotamian shadufs in arid climates?

💡 Explanation

When irrigating arid land using shadufs, groundwater salinization increases because the shallow water table evaporates, depositing accumulated salts at the surface. Therefore groundwater salinization results, rather than erosion, collapse or eutrophication, requiring different irrigation failure mechanisms like excessive water flow or nutrient introduction.
