| Abstract: | The results derived from analyzing the long-term dynamics of the runoff of sediment loads of the main rivers in the agricultural areas of the Lake Baikal watershed basin are discussed. The analysis revealed a descending trend of the erosion processes caused by an abrupt change of agricultural activity in the region, i.e. a reduction in the area of arable and pasture lands in the late 20th century. It is shown that a decrease in basin erosion intensity promotes stabilization of desertification processes and, in general, an improvement of the ecological situation in the Baikal region. |
