    Kissidougou in Guinea, West Africa, is characterised by so-called 'forest islands', relics - it was assumed -of original dense forest cover. It was also assumed that local cultivation practice was to blame for the destruction of the trees. However, as collaborative research led by the School of Oriental and African Studies, the Institute of Development Studies and Guinean researchers discovered, villagers had a different story to tell: that the forest islands had in fact been established over several generations as part of a process of deliberate forest management.

    Policy makers as well as scientists have started to acquire an honest appreciation of the possibilities of reducing the wastage of materials which could be profitably utilized for improving or maintaining soil productivity. In addition, the great opportunities offered by making more efficient use of the potentials of biological nitrogen fixation in farming systems are now fully recognized. A number of recommendations and suggested guidelines were made by the various Working Groups during the two-week Workshop.

    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.
