Soil erosion, gullying and landslides have been recognized as the major environmental threats in the Moldavian Plateau of Eastern Romania. Five stages of land degradation over the last two centuries can be depicted, namely:i) a preparing stage for future land degradation (1829–1999) when the most dynamic change of the native landscape was recorded; ii) a transitory stage (1900–1920) associated with the extension of the cultivated land up to 48% of the total area; iii) the climax stage (1921–1970) defined by both the traditional up and down hill farming and the peak rate of land degradation during 1960's; iv) a decreasing tendency of land degradation (1971-1990) as a result of the extension of conservation practices and the rainfall pattern; v) the present-day revival of land degradation associated to the Act no. 18/1991 when up and down hill farming under small plots is on the screen again. The main objective of this study was to define the process:based erosion and sedimentation by providing quantitative information from long-term field measurements in small catchments.
