    The second phase of the Sustainable Management of Marginal Drylands (SUMAMAD-2) project began in 2009 following a preparatory meeting on the project held on 3–6 June 2008 in Amman and the Dana Biosphere Reserve, Jordan, and was hosted by the Royal Society for the Conservation of Nature (RSCN). The extended SUMAMAD-2 to other world regions included South America (Bolivia) and Africa (Burkina Faso).

    The world’s drylands are among the most vulnerable ecosystems on our planet. Desertification and land degradation are affecting huge land areas, jeopardizing the livelihoods of millions of people. Unsustainable management practices in dryland cultivation and pastoralism have given rise to widespread soil erosion, reduction of the biological production of soils, reduction of vegetation cover, and depletion of surface and groundwater resources.

    The conference reviewed the current state-of-knowledge of dryland ecosystems; it identified important knowledge gaps for defining future paths of research into drylands; and it commemorated fifty years of dryland research in the UN system in the context of the International Year of Deserts and Desertification. The conference - in a cross-cutting manner - also addressed issues related to research and science needed for dryland conservation, policy options for sustainable dryland development, and necessary interventions and

    Millennium Development Goal Number Seven is particularly concerned with the safeguarding and provision of freshwater resources to all human.beings; this is a major challenge – and perhaps even the main challenge – for all the world’s drylands. SUMAMAD project aims at the sustainable management of marginal drylands, where the scarcity of water imposes restrictions for the productivity of each particular ecosystem. It is needed therefore to look into the entire water complex so as to promote a wise and sustainable water use. However,

    As marginal drylands, all project sites share similar environmental constraints such as recurrent droughts,
    water shortages, shallow soils and the threat of land degradation. As they occur in different economic,
    political, social and cultural environments, it will be interesting to address similar bio-physical problems
    from different perspectives stemming from varying anthropogenic factors. More importantly, the

    The drylands of the world occur on every continent, covering some 41% of the terrestrial surface. One third
    of humanity inhabits these harsh degrading landscapes, eking out a living through adaptive processes that
    have served them well until recent increases of land degradation. Growing pressures from population growth,
