Crop water productivities (CWP) at two scales were estimated based on water use analysis. Impacts of climatic and agricultural factors on crop water productivity were analyzed. Sensitivity of CWP to each climatic and agricultural factor exist obvious differences. Agricultural inputs and irrigation efficiency increase were the key drivers for CWP variation.
