    The aim of the project was to develop and implement a web-based GIS tool for defining sustainable
    land management (SLM) options by social-ecological context at global scale. This Global Geoinformatics Options by Context (GeOC) tool aims to support the implementation of SLM practices
    by the international community. The GeOC is designed to provide stakeholders/projects and
    programmes with plausible, robust extrapolation domains for guiding decisions on SLM options,

    To help break the cycle of poverty, improve food and nutritional security, halt or reverse the alarming process of resource degradation in the dry areas, and help communities adapt to the impacts of climate variability and change, ICARDA’s Strategic Plan 2017-2026 outlines our research and organizational approach for action to achieve our vision of thriving and resilient communities in the dry areas of the developing world.

    This issue of Caravan showcases some of ICARDA’s efforts of coping with climate change in dry areas with improved water land management and resilient production systems. These include initiatives in conservation agriculture which provide sustained production levels while conserving the ecosystems on which our entire food system is dependent upon. ICARDA continues to make significant contributions in the promotion of sustainable water land management approaches and technologies devised by researchers and farmers.

    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.

    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.

    Soil erosion is a natural process causing serious land degradation problems. In Tunisia, soil
    erosion represents a serious environmental problem. The Rmel watershed located in the
    Governorate of Zaghouan in north-eastern Tunisia and covering an area of 679 square
    kilometers, suffers from this problem. It was thus selected to estimate annual soil loss using the
    Revised Universal Soil Loss Equation (RUSLE), and geographic information system (GIS).
    RUSLE model’s parameters (R, K, LS, C, and P) were derived from digital elevation model
