    Túnez, África septentrional

    During the last two decades, the Tunisian government has engaged in a vast program for the conservation and mobilization of natural resources. In the Jeffara region, which encompasses the study site, huge works for soil and water conservation (water harvesting) have been implemented whose immediate effects are visible but their efficiency in both the short and the long term need to be assessed and evaluated in detail (De Graaff J. and Ouessar M., 2002).

    Biodiversity in rangelands is decreasing, due to intense utilization
    for livestock production and conversion of rangeland into cropland;
    yet the outlook of rangeland biodiversity has not been
    considered in view of future global demand for food. Here we
    assess the impact of future livestock production on the global
    rangelands area and their biodiversity. First we formalized existing
    knowledge about livestock grazing impacts on biodiversity,
    expressed in mean species abundance (MSA) of the original

    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.

    The overall aim of the project is to identify physical and institutional interventions to improve water management using an integrated approach across scales (from farm to main canal levels) and encompassing water quantity–quality interactions. The project’s geographical focus is the Nile Delta in Egypt.
    The project was originally planned for four years. Due to a policy change announced by the Australian Government in reducing the aid investment in the Middle East and North Africa, including Egypt, the duration of the project was reduced to three years.
