While soils are as essential to human society as air and water,soil degradation has not received nearly as much attention as the threats to these other elements.On the map of water erosion of Europe,Southern Europe is red"colored".Erosion in the Balkan countries,through both on and offsite effects is a major cause of soil and water degradation.This paper compares erosion control works in several countries from the Balkan region(Macedonia,Serbia,and Bulgaria).The basis for comparative analyses was various country reports as well as available published papers.Quantitative method-text analyze method was used for these study.Natural conditions in the Balkan countries contribute to the appearance of various erosion forms and the intensity of the erosion processes.Over the history of these countries,people who settled this region used the available natural resources to fill their needs(tree cutting,incorrect plugging,overgrazing),which contributed to soil erosion.Organized erosion control works in the Balkans started in the beginning of the 20th century(1905 in Bulgaria).The highest intensity of erosion control works were carried out during the period 1945-1990.Various erosion control works were launched.Bulgaria had a large anti-erosion afforestation,almost 1 million ha.Bulgaria's ecological river restoration approach has been in use for almost 50 years.Serbia contributed significant erosion and torrent control works on hilly agricultural areas.Specific screen barrages and afforestation on extremely dry areas are characteristic in Macedonia.A common characteristic for all countries is a high decrease in erosion control works in the last 20 years. 展开更多
