Abstract
This research aims to assess the environmental impact of municipal solid waste landfills on vegetation in the vicinity of landfill sites, focusing on two cities in Kazakhstan, Stepnogorsk and Kokshetau. The study utilized vegetation indices, specifically the Normalized Difference Vegetation Index (NDVI) and the Soil-Adjusted Vegetation Index (SAVI), to assess the health and density of vegetation. Landsat 8 OLIC2L2 satellite imagery spanning from July to August in the years 2017–2022 was processed in the ArcGIS program. The SAVI was employed to adjust for soil type and vegetation density. In the Stepnogorsk and Kokshetau sanitary zones, NDVI values during summer (2017–2022) ranged from 0.12 to 0.21, with SAVI values for Kokshetau between 0.15 and 0.25. ArcGIS analysis shows increased degradation and desertification, influenced by wind direction. NDVI and SAVI remote sensing effectively assessed vegetation in the sanitary zones of both landfills. The research underscores the significant environmental impact of municipal solid waste landfills on the surrounding vegetation.
