    África oriental, Tanzania

    Arid, semi-arid and dry sub-humid areas cover 61 % of Tanzania (United Republic of Tanzania, 1999) and, over the past decades, several restoration projects have worked toward reversing degradation in these areas (Kikula, 1999; Kisanga et al., 1999). These projects have addressed from social and ecological perspectives and have spanned for decades, thereby allowing for a genuine opportunity to identify and articulate lessons learned and develop good practice guidelines for restoring productive capacity of drylands.

    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.

    The goal of WLI is to improve the livelihoods of rural
    households and communities in areas where water
    scarcity, land degradation, water quality deterioration,
    food security and health problems are prevalent in eight
    participating countries including Egypt, Iraq, Jordan,
    Lebanon, Palestine, Syria, Tunisia, and Yemen. The main
    objective is to develop and pilot test integrated water and
    land management strategies.

    Túnez, África septentrional

    An innovative, low-cost methodology was developed to assess the potential of sites in Tunisia for supplemental irrigation and water harvesting. The methodology, which uses commonly available technologies and information such as remote sensing and a Digital Elevation Model (DEM), was developed and tested using newly constructed hill reservoirs (used to capture surface runoff) and traditional water harvesting systems.

    The objectives of this report are to evaluate and test, with community participation; the benchmark water management options which sustainably improve water productivity, net return per water unit, and optimize water use. The strategies evaluated have to be economically viable, socially acceptable, and environmentally sound in the three different agricultural eco-systems.

    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.
