    Afrique septentrionale, Égypte

    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.

    Asie occidentale, République arabe syrienne

    In the Mediterranean mountain areas of NW Syria, land degradation is a serious problem (Masri et al, 2005). Olive orchards dominate the landscape in Afrin area, and olive oil represents the most important cash income source for rural communities in this area. However, olive yields in many orchards have been decreasing steadily over the last 20 years. Low return to labour has resulted in livelihood insecurity, increased reliance on off-farm labour, and out-migration.

    As the world’s population continues to rise, there is
    an ever increasing demand for our land to produce
    a diverse range of products such as food, timber,
    and fuel. Our growing need for these goods is
    leading to higher levels of competition between
    different land uses and, as a result, land users. Not
    only is the quantity of land available for production
    under current technical and economic conditions
    limited, but there is also growing evidence that the
    quality of our land is degrading (Safriel, U. N. 2007;

    Asie occidentale, Jordanie

    Jordanian rangelands are a source of valued livestock produce, carbon storage, biodiversity, and medicinal plants. They also serve as watersheds that receive rainfall, yield surface water, and replenish groundwater throughout the area east and south of the western Jordan highlands. Appropriate land management, which is currently lacking, can protect and maximize these services for society. With the acceleration of desertification, land degradation and drought during the twenty-first century in the arid and semi-arid regions of Jordan, these services are becoming jeopardized.

    The Kelka forest in the Mopti region of Mali is important for the provision of ecosystem services like carbon sequestration and maintenance of the hydrological cycle. The Kelka forest area occupies more than 300, 000 hectares with 15
    villages within and around its boundaries. The forest resources and soil fertility of the forest are in continuous decline due to a combination of climatic and human induced factors. For example, the availability of firewood has halved

    Afrique orientale, Éthiopie

    Soil erosion and deposition values were estimated using pixel based landscape information and the Unit Stream Power Erosion Deposition (USPED) model, which works with the Universal Soil Loss Equation (USLE) parameters. The USPED model was adapted to Ethiopian conditions based on evidence from the Soil Conservation Research Programme, and calibrated and validated using data from former research stations as well as the Abbay (Blue Nile) Basin. Additionally, some of the USLE parameters were reduced in order to achieve a satisfactory approximation of sediment loss for the Abbay Basin.

    Asie central, Ouzbékistan

    Agricultural production systems are a vital lifeline of the rural farming community in Central Asia. However, shrinking natural resource base, increased land degradation and severe irrigation water scarcity render current crop production practices not sustainable as these perform below their potential. Though there is considerable scope for improving productivity through bridging the yield gaps and introducing sustainable land management practices. However crop productivity and production pattern varies across scales, mostly driven by irrigation water availability, markets, and

    Land degradation and desertification are among the biggest environmental challenges of our time. In the last 40 years, we lost nearly a third of the world’s arable farmland due to erosion, just as the number of people to be fed from it almost doubled. That’s why the UN General Assembly declared 2015 as the International Year of Soils. And the good news is that this new report shows that while Africa remains the most severely a«ected region, the benefit of taking action across the continent outweighs the cost of implementing it: not just by a little, but by a factor of seven.

    Sustainable Land Management (SLM) are required to achieve Land Degradation Neutrality (LDN). SLM options are fitted to the social, economic and ecological contexts. The high contextual diversity of drylands in particular prevents the design and application of “uniform blanket” policies to promote SLM over large scales where significant impact is expected.

    Land degradation is a pressing concern that reaches
    across all republics of Central Asia and is increasingly
    affecting the economy and quality of life in each.
    The resulting loss of arable land particularly affects
    the rural poor, who depend directly on what
    the land can provide for their very survival and
    livelihoods. The breakup of the Soviet Union led to
    mass de-collectivisation of agricultural frameworks
    across Central Asia, with formerly centralised land
    management regimes dissolved. The reorganisation
