    Even if preliminary results have shown that a protection period of 3 years is not sufficient for disappeared species to appear nor for succession to reach a next stage, mainly in the degraded Stipa tenacissima community, the reintroduction of the rest “gdal” practice seems to be beneficial and a suitable tool to manage sustainably the arid rangelands under changing climate. Thus, the evidence suggests that, during short-term rest from grazing (2 years), vegetation cover, density, rangeland production and carrying capacity can be improved.

    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.

    The threat that the degradation of terraces in the highlands of Yemen poses to the livelihood of rural households and to national economic development has been widely recognized. The aim of this study was to contribute to the development of policy recommendations for the improvement of the life of rural families in the Yemeni mountains. Three small mountain watersheds (200-700 ha) in the northern, middle and southern mountain regions of Yemen were selected as the testing grounds for this study.

    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

    Research on micro-catchment rainwater harvesting techniques by ICARDA and Jordanian
    scientists has led to the establishment of semicircular bunds on contour ridges and furrows
    (using GPS laser-guided Vallerani machine) and runoff strips in two communities of Jordan
    Badia. As an outcome of this research, an effective micro-catchment laser-guided system was
    identified for rainfall harvesting, which has led to improved water availability, increased
    vegetative cover and improved soil health, and provided rural communities substantial sources

    This report is the second in a series of three publications that comprises an overview of the Iraq Salinity Assessment. This report documents solutions and impacts identified in the first report in this series. The third report in the Assessment proposes investment options and methods to analyze the investment options to manage and remediate salinity in Iraq.
    This report has been compiled from project contributions from a number of authors across all of its seven technical Components.

    Dryland (arid and semi-arid) ecosystems occupy more than 41% of global land area and are home to 2.5 billion people. More than 50% of South Asia’s dryland ecosystems are located in India. Drylands contribute about 40% of the total food grain production and support two thirds of livestock population. Despite these important roles, agricultural production systems in the drylands are facing numerous challenges that threaten their resilience and future sustainability. This paper demonstrates some of the challenges and draws implications for priorities research and strategies.

    The shortage of water in arid zones represents the most serious obstacle to poverty reduction because it limits the extent to which poor producers of crops and livestock can take advantage of opportunities arising from emerging markets, trade, and globalization. Water shortage in arid zones limits the variety and quantity of crop and livestock products a smallholder can produce, thus narrowing their range of options.
