    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
