This study aims to assess global experience on agricultural water management under different scenarios. The results showed that trend of permanent crops to cultivated area, HDI, irrigation water requirement, and percent of total cultivated area drained is increasing and trend of rural population to total population, total economically active population in agriculture to total economically active population, value added to GDP by agriculture, and the difference between NIR and irrigation water requirement is decreasing. The minimum and maximum values of pressure on renewable water resources by irrigation, are related to the third and first scenarios by 2035 (6.1%) and 2060 (9.2%), respectively.
