This paper presents an assessment of pasture areas of Kazakhstan with different degrees of degradation of desert, foothill semi-desert (vertical zoning), semi-desert (latitudinal zoning), dry-steppe, steppe and forest-steppe zones using GIS technology based on field survey data with indicators of physical (soil) and biological (botanical) indicators and medium and low resolution satellite data. The aim of this work is to develop an interactive geo-information map of pasture degradation in Kazakhstan. To determine pasture degradation, the remote sensing (RS) method was used with all available mapping material and satellite data from Landsat 8, Sentinel 2, Modis TERRA, which resulted in analysis of vegetation indices NDVI, SAVI, BareSoilIndex, SalinityIndex, Top-SoilGrainSizeIndex for 33 monitoring areas in 12 oblasts in the context of degradation contours. A database for all soil-geographical zones was compiled and an interactive geo-information map of the degree of pasture degradation for the studied soil-geographical zones of Kazakhstan at a scale of 1:750 000 was developed, which includes soil, botanical characteristics and measures for their management and improvement.
