Integrating Seismic and Environmental Hazard Factors into State Land Cadastral Valuation: A Case Study of the Bostandyk District, Almaty

Abstract

Existing state cadastral land valuation methodologies often focus exclusively on economic factors while ignoring geo-environmental hazards. This paper proposes a mechanism for incorporating seismic risk indicators and environmental degradation into the cadastral model to improve pricing accuracy. Using four cadastral blocks in the Bostandyk District of Almaty as a case study, the authors applied MAVT and AHP methods, integrating seismic microzonation data and satellite monitoring (Sentinel-2, Landsat 8) to calculate a comprehensive risk coefficient (Krisk). According to spatial analysis data, the presence of natural hazards serves as a valid criterion for reducing the cadastral valuation of vulnerable land plots by 20–45%. The proposed methodology ensures a balance between market valuation and environmental safety, representing a scalable tool for urban land management in seismically active zones.
