摘　　要：The western edge of the Jord Tannourine-Aaqoura plateau(Lebanon)is a Mediterranean mountain region that unites the suitable conditions for water erosion:abundant rain,steep slopes,ravaged natural vegetation cover,and soil susceptible to degradation.However,the agricultural terraces developed for decades remain a robust practice to limit runoff and expand the useful agricultural area.To determine water erosion and the role of anti-erosion practices,the adopted methodology is based on the universal USLE equation revised(RUSLE).The combination of model parameters in a GIS has made it possible to define that water erosion can exceed 51 t/ha/year,mainly in sectors marked by the absence of agricultural terraces,and not associated with dense plant cover.In contrast,terraced slopes induce losses of less than 16 t/ha/year.The implantation of a network of metal rods does the validation.Faced with this risk of degradation,it seems essential to recommend protective agricultural techniques.
