    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

    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.

    Implementation of land management policies influences land use and hence
    causes environmental change. Taking the Ordos rangelands in China as a case
    study, this paper explores the potential of remote sensing to assess in dryland
    areas the impacts of policies on the environment. Thirteen Landsat images of the
    period 1978 2010 were acquired and those corresponding to the starting dates of
    implementation of different policies were selected for land-cover change analysis;
    others were used to check the detected change and track the normalized

    This laboratory manual of analytical methods has been compiled to be used primarily by research
    assistants, technicians and student trainees working in the laboratory. The methods have been
    selected from different sources and adapted for routine analyses in the WANA region. A detailed
    description of the methods can be found in the original publications listed in the references. As
    analytical techniques are developed and improving, this manual will be subject to continuous
    revision. Any helpful suggestion and feedback from users is most appreciated.

    Ethiopia has great agricultural potential as it has vast area of fertile land, diverse climate, sufficient annual rainfall, & abundant labor force. However, the current performance of agric. is far below the potential, partly due to soil erosion & land degradation, lack of using improved technologies, lack of supportive services, poor socioeconomic infrastructure, & many more interrelated socioeconomic factors. Consequently, food insecurity & poverty have remained common features in the rural community.

    Water scarcity and land degradation are widespread problems that affect agricultural productivity, food security and environmental quality in several parts of the world, particularly in the dry areas. Sustainable management of soil and water is necessary to optimize the use of limited rainwater for crop production and to decrease soil erosion. One management option is utilizing rainfall more efficiently through water harvesting. In arid areas, different types of water harvesting techniques (WHT) are being developed by

    Drylands are characterized by physical water scarcity, often associated with land degradation and
    desertifi cation. Other factors that contribute to these problems include high population densities,
    unwise agricultural practices and overgrazing. However, while desert ecosystems are fragile and
    vulnerable and can collapse in the short term, given the right conditions and protection, these
    areas also have a great potential for recovery. Examples of the recovery of areas have led to the
