2.3.1. AquaCrop Model Description

AquaCrop is a crop water productivity model developed by FAO's Land and Water Division in Rome, Italy. This crop model was created to address food security issues and assess the effect of environment and field water management on agricultural production (www.fao.org/aquacrop/overview/en/, accessed on 15 January 2022). This model simulates the response of herbaceous crop yields to water. It is particularly well suited to conditions in which water is a limiting factor in agricultural production [31]. AquaCrop combines precision, simplicity, and robustness; it is widely used around the world given the limited number of inputs required for its simulation process [32]. AquaCrop can also simulate crop growth under CC scenarios by taking into consideration different CO2 concentrations scenarios. However, AquaCrop does not take into account the negative impacts of pests, diseases, and weeds on yields [33].
