  23. SESSION 3 Presentation of the proposed soil indicators -EROSION: Objectives Data Sources Land erosive status indicator Land Use Changes indicators Changes in agricultural areas and Soil Erosion Indicators Conclussions Proposed Soil Indicators on ErosionConclussions1-The proposed indicator on land erosive status is interesting to assess the present situation of soil degradation (30% in the test region). It is useful for its simplicity and applicability, but new analysis are needed. 2-Soil erosion evaluation is highly depending on territorial information. Integrated approach is required and land use monitoring is essential (18% of the territory experimented land use change between 1991-1999). 3-The proposed indicators change in agricultural areas/soil erosion for the test region illustrated global incidence of these land uses changes on soil erosion, and the unequal incidence of the changes induced on natural areas (+202% of soil loss) and agricultural areas(-5%).
