8.3- Zones Under Threat of Erosion

The indicator is a status indicator representing the areas exposed to erosion and the degree of this erosion.

Turkey’s geographical position, climate, topography and soil conditions are the main factors, which affect the deterioration of the land and increase the sensitivity of drought. There are various erosion types observed all over the country; while water erosion is the most widespread one. 61.2% of the country territory faces severe and very severe water erosion problem.

Given below is the erosion information from the Digital Soil Maps (scale 1/25,000) that have been prepared using GIS systems and classified according to the American Taxonomy, relying on field surveys of Repealed General Directorate of Rural Services (soil survey and mapping data 1982-1984).
