This could be interpreted due to the change in the land use land cover in the study area from agricultural land to uncultivated lands which reduced the agricultural practices in these areas and decreased the soil loss. Another reason may be due to the differences in acquired time of the satellite images that were used to derive the NDVI, the image of 1992 acquired on May 31st and the 2009 image acquired on the 1st of May. With difference in these times the plant coverage could have big changes which affect the C factor and finally the soil loss in the study area.
