THE TECHNOGENIC COMPONENT OF ECOLOGICAL AND GEOLOGICAL RISKS OF LANDSLIDE HAZARD ON THE EXAMPLE OF CADASTRAL PLOTS OF KOSIV DISTRICT

Abstract

The purpose of the study presented in this paper is to analyse landslide hazard processes by assessing the impact of anthropogenic factors on land use within the Kosiv district of Ivano-Frankivsk region. The growing negative consequences of landslide processes within the study area, especially in the Ukrainian Carpathians, necessitates the creation of new approaches to land resources assessment and civil engineering in order to reduce the negative impact of landslides on the environment and human activity. Landslide processes were studied using geophysical, GPS and geostatistical data analysis methods. Based on the map layers of the land cadastre and the landslide risk map of Kosiv district, a vector analysis was conducted to assess the risk of each site according to its cadastral number. QGIS was used to calculate the environmental and geological risks of man-made components of landslide-prone areas using geoinformation and geostatistical analysis tools. An important result of the study was the construction of landslide risk maps for land plots based on the State Geocadastre data using the Kadastr.Live dashboard plug-in. For the first time, an analysis of the anthropogenic components of landslide risk in the Kosiv district was carried out as a basis for assessing the landslide risk of individual land plots. The risk analysis was carried out on the example of individual plots as a basis for clarifying regulatory and financial assessments, changing the designated purpose of land plots and carrying out economic activities that require hydrogeological research. The methodology of dividing landslide hazard assessment factors into natural and anthropogenic ones allows to identify the areas with the highest probability of landslide occurrence and activation within the studied territory when studying the characteristics of natural factors.
