Identifying rural settlements at risk of landslides in nomadic ecosystems (case study: Paveh county)

Considering the existence of numerous villages in nomadic ecosystems and the destructive effects of natural disasters on life, finances, and the environment, identifying rural settlements at risk of landslides as one of the most common natural hazards in the world and Iran can be effective in managing these crises.Purpose of the research: The purpose of the current research is to identify rural settlements at risk of landslides in the nomadic ecosystem of Paveh.

To achieve the goals of this quantitative and applied research, 18 factors affecting landslides were used and to weigh them from the opinions of 15 university professors, researchers and experts. for extract landslide points, Sentinel 1 radar images were used in Snap and Google Earth software environment and to analyze the data, ArcGIS software was used with the fuzzy overlay method.Geographical area of research: The geographical area of this study is Paveh city, located in Kermanshah province

The results of the research showed that in terms of sensitivity to the occurrence of landslides, 39% of the entire area of the county is located in areas with very low and low risk, 30% in areas with medium sensitivity and 31% in areas with high and very high sensitivity. Also, the results showed that it is located among the 53 populated settlements of Paveh county 35.8% of villages in areas with very low and low risk, 28.3% in the area with moderate sensitivity and 35.9% in high and very high sensitivity areas.

Considering the exposure of a significant number of rural settlements to the risk of landslides, the preparation of a sensitivity map to the occurrence of environmental hazards in these geographical spaces should be prioritized in land development policies and plans.
