Abstract

The environment condition in the central economic region of Mongolia has been degrading due to overgrazing, legal and illegal mining, arable land, expansion of settlement areas, migration to cities from rural areas, population growth. Determining the intensity and spatial distribution of the human impact activities on environment is important to plan and implement suitable protection, rehabilitation, and monitoring measures. The aim of this research is assessing the impact of human activities in the Sharyn Gol River Basin located in the central economic region of Mongolia and identifying and mapping the spatial distribution of the impact. The Human Footprint method, Geography Information System based Multi Criteria decision analysis (GIS based MCDA) and Analytic Hierarchy Process (AHP) were used to assess and the map human activities impact. Five categories of data (herders’ seasonal location, dirt road distribution, settlement area, mining and agriculture land) were selected for this study. The data were obtained from Google Earth Pro and Landsat OLI imagery. Impact assessment was conducted for each type of the land use in order to create impact layers. After calculating the weight of each impact layer by GIS based MCDA and AHP method, the impact map of human activities was created by combining the impact layers. Sharyn Gol River Basin’s human impact assessment estimated 4267.23 ha is severely, 20396.33 ha is strong, 55148.35 ha is moderate, 97060.18 ha is weak, and 117489.57 ha is very weak. Considering the spatial distribution of human impacts, the highest impacts are in settlement area with high density of dirt roads, mining areas, agricultural lands, and pasture area along the river valleys. The results of the human activities impact assessment and mapping study in the Sharyn Gol River Basin can be used as a reference material to plan and ensure the implementation of Government policies and decisions.
