    Climate change has led to more severe conditions throughout the world as well as in Morocco. In general, rainfall has declined and average temperatures have increased. These new rainfall patterns are threatening water supplies. Fluctuations and reductions in annual rainfall have led to severe and frequent droughts throughout the Central and West Asia and North Africa region. Consequently, water resources have become scarce. Increasing municipal and industrial demand for water has resulted in steadily decreasing allocations for agriculture.

    CropSyst is the crop growth model chosen as a decision tool for the Tadla Benchmark project. CropSyst is a daily time step simulation model. The model was developed to serve as an analytic tool to study the effect of cropping systems management on productivity and the environment. The model simulates the soil water budget, soil– plant nitrogen budget, crop canopy and root growth, dry matter production, yield, residue production, and decomposition. Management options include cultivar selection, crop rotation, irrigation, nitrogen fertilization, tillage operations, and residue management.

    The best use of irrigation water is reflected in the strategic approach of the Ministry of Agriculture and the major research objectives of institutions working on sustainable irrigation management. Related research programs can be summarized as follows:
    • crop water requirements;
    • irrigation techniques, especially surface irrigation;
    • irrigation scheduling; and
    • soil and water quality as affected by irrigation and drainage.

    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.

    MENA’s permanent cropland – currently at less than 6% of the total land area – is shrinking due to serious land degradation and recurrent droughts. The region faces the most severe water shortage in the world with annual renewable water resources per capita estimated to decline from 1,045 m3/yr in 1997 to 740 m3/yr in 2015.

    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.

    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
