Abstract
The USLE / RUSLE method is the most widely used method in the world for
calculating erosion intensity expressed as soil loss. IN the latest period, a map of soil loss EU
was made by this method. One of the key parameters for applying the RUSLE method is the R -
erosive energy factor for which a global world map model has been created too. In the Republic
of North Macedonia there are no available data to use original access for calculation this factor.
That is why the approach is based on the annual precipitations. Several equations developed
in different parts of the world were analyzed. Calculation was done for data from 17 gauges
stations in the country, and at the same time modeling has been done for the whole country on
the basis of altitude. Comparison of the obtained values with the results for the border areas and
high mountains in Greece and Bulgaria, showed that they are realistic and enable o be further
applied in the final modeling for creation of Soil Loss map in the Republic of North Macedonia
using RUSLE method. Average R - factor in states amounts to 533 (MJ mm ha-1 h-1 yr-1), and
rises from 437 (MJ mm ha-1 h-1 yr-1) in Krivolaka district in the central part of the country, to
835 (MJ mm ha-1 h-1 yr-1) in the southwestern part of Shar Planinа and Korab mountains.
