Аннотация |
Current medium- and small-scale estimates of soil erosion in Russia are very few. At the same
time, a favorable situation has now developed for assessing the rates and volumes of soil erosion losses. Ero-
sion models adapted to available digital elevation models, various farmland maps, and climate databases are
now available to researchers. We have estimated the rates and volumes of soil erosion with the use of different
maps of cropland: world cover from the European Space Agency (ESA WC), global land cover and land use
from the University of Maryland (GLCLU), the official unified federal information system of agricultural
land (UFIS AL) from the Ministry of Agriculture of the Russian Federation, and the original conventionally
reference land cover map of Alekseevskii district of Belgorod oblast. It has been found that the UFIS AL map
gives cropland areas close to the average from first three maps. Public access maps (ESA WC and GLCLU) give
maximum and minimum estimates of cropland, respectively. A comparison with the conventionally reference
large-scale map shows that the accuracy of the UFIS AL does not exceed 90%; the accuracy of ESA WC and
GLCLU maps is 84 and 83%, respectively. The total area of cropland in Belgorod oblast varies slightly (from
1445 to 1586 thousand hectares), which is favorable for erosion modeling. Deviations from the average rates
of soil erosion calculated using different maps of cropland in the region as a whole are up to 7%; for some
districts, they reach 27%. Thus, current estimates of soil erosion at the regional level can be carried out with
an error of at least 10–15% only as a result of the uncertainty in mapping the boundaries of cropland. For Rus-
sia as a whole, data on the area of cropland vary significantly: from 80 to 132 million hectares. Consequently,
the use of existing maps of cropland can lead to significant uncertainties in soil erosion estimates averaged at
the level of the subjects of the Russian Federation and large regions. |
