The GLASOD and ASSOD projects reflect the present status of human-induced soil degradation and its impact on food productivity related to productivity changes observed in the recent past. However, there is a great need for well-documented, reliable soil information and other related data at national and regional levels to better understand and qualify the impact of changing soil conditions or biomass production. %K soil degradation %K GLASOD project %K SOTER project %K ASSOD project %U http://www.international-agrophysics.org/artykuly/international_agrophysics/IntAgr_1998_12_1_37.pdf
