In this study, an economic evaluation of water-use efficiency technologies proposed and tested by the agronomic team in the Tadla Irrigated Perimeter was carried out. To capture climatic variability, the analysis was conducted during two contrasting years (dry and wet).

CropSyst is the crop growth model chosen as a decision tool for the Tadla Benchmark project. CropSyst is a daily time step simulation model. The model was developed to serve as an analytic tool to study the effect of cropping systems management on productivity and the environment.
