There is a urgent need for a better understanding of the risks of soil degradation and their geographical distribution as well as a better knowledge of where degradation occurs at present. it would be desirable to combine soil conservation activities with other elements for increasing crop production.Erosion, salinity and alkalinity and the loss of soil fertility seriously reduce the natural potential of soils to produce food fibres. During the meeting, many criteria to assess the various types of soil degradation were outlined by the experts.
