Accelerated soil erosion and land degradation represent major environmental problems for agricultural lands. Reliable information on the rates of soil loss is urgently needed. The traditional techniques for documenting rates of soil loss may meet this need, but face many limitations. The fallout radionuclides, especially Cs and Pb, are increasingly used as effective tracers to quantify soil erosion rates, and they represent a valuable complement to the existing classical methods. This paper aims to introduce the basis for assessing soil erosion rates on cultivated and uncultivated slopes by using Cs and Pb measurements, to compare the Cs and Pb reference inventories, and to report several case studies undertaken in the hilly area of Sichuan Basin and the Three Gorges area of China.
