This review of soil erosion(SE)studies in Russia focuses on two main tasks:(i)ensuring the completeness and reliability of SE data in Russia,a large country(17.1 million km2)with a variety of natural and socio-economic causes of land degradation,(ii)assessing the possibility of including a SE indicator among the indicators of land degradation neutrality(LDN).A wide range of statistical,remote sensing,mathematical modeling *** results of scientific and field studies obtained at different levels were *** is asserted that in Russia the total area of eroded lands and those under erosion risk occupy more than 50%of all agricultural lands,whereas soil fertility of croplands decreased in Soviet time(from 1950s to 1980s)by 30-60%only due to water ***,recent scientific studies indicate a decrease in erosion rate and in the area of eroded land during the last 30-40 years as a result of abandonment of arable land and subsequent overgrown with natural *** climate change resulting in decrease of the depth of soil freezing,flow of spring runoff also adds to the decrease of soil *** SE indicator was suggested as an important complement to three global LDN *** national and subnational level,it can be interpreted through such indices as"Rate of soil loss"(ton ha-1 yr-1)and"Total soil loss"(1000 tons,in certain area during selected time period).At local level the set of indices can be wider and site-specific,including those obtained through remote sensing data by using the classifier of thematic applications of remote sensing technologies;the example was tested at the local site.
