    Climate change has led to more severe conditions throughout the world as well as in Morocco. In general, rainfall has declined and average temperatures have increased. These new rainfall patterns are threatening water supplies. Fluctuations and reductions in annual rainfall have led to severe and frequent droughts throughout the Central and West Asia and North Africa region. Consequently, water resources have become scarce. Increasing municipal and industrial demand for water has resulted in steadily decreasing allocations for agriculture.

    This is the fundamental scope of the Irrigation Benchmark Project, where the emphasis was placed on introducing and implementing new water saving technologies. Additionally, emphasis was laid on the participation and involvement of farmers in water users’ associations (WUA) and other community organizations, as well as with government organizations – particularly, those concerned in the Extension Service of the Ministry of Agriculture.

    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. The model simulates the soil water budget, soil– plant nitrogen budget, crop canopy and root growth, dry matter production, yield, residue production, and decomposition. Management options include cultivar selection, crop rotation, irrigation, nitrogen fertilization, tillage operations, and residue management.

    The best use of irrigation water is reflected in the strategic approach of the Ministry of Agriculture and the major research objectives of institutions working on sustainable irrigation management. Related research programs can be summarized as follows:
    • crop water requirements;
    • irrigation techniques, especially surface irrigation;
    • irrigation scheduling; and
    • soil and water quality as affected by irrigation and drainage.

    The literature identifies two common approaches for estimating technical efficiency. One approach is based on non-parametric, non-stochastic, linear programming. This suffers from the criticism that it does not take into account the possible influence of measurement error and other noise in the data (Coelli, 1995). The second approach uses econometrics to estimate a stochastic frontier function, and to estimate the inefficiency component of the error term. The disadvantage of this approach is that it imposes an explicit and possibly restrictive functional form on the technology.
