    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.

    Maroc, Afrique septentrionale

    Rice is one of the major crops cultivated predominantly in flooded paddies, thus
    a large amount of water is consumed during its growing season. Accurate paddy rice maps
    are therefore important inputs for improved estimates of actual evapotranspiration in the
    agricultural landscape. The main objective of this study was to obtain flooded paddy rice
    maps using multi-temporal images of Moderate Resolution Imaging Spectroradiometer
    (MODIS) in the Krishna River Basin, India. First, ground-based spectral samples collected

    This study was carried out at the communal rangelands of Dhahar, Saharan area of Southern Tunisia, to assess the impact of restoration and rehabilitation techniques on natural vegetation cover. Two rangeland types (Rhanterium suaveolens and Anthyllis sericea) were subjected to three management modes: two years rest (M), reseeding Stipagrostis pungens (S) and free grazing (T). In all plots, total plant cover, species richness and grass density where determined in spring 2008.
