Abstract: In the present application, a method for assessing water shortage risk, device, computer device and storage medium are provided, wherein the method for assessing water shortage risk comprises: acquiring a volume of blue water flowing into soil of a to-be-assessed-area within a target time period, and a volume of retention water flowing into and retained in the soil of the to-be-assessed-area within the target time period; and determining a water shortage risk indicator of the to-be-assessed-area indicating a degree of water shortage risk of the to-be-assessed-area, according to a ratio of the volume of blue water to the volume of retention water. A higher ratio of the volume of blue water to the volume of retention water indicates poor ability of the soil's water to meet the demand for use and greater degree of the water shortage risk of the soil.
