Abstract
This study employs Sentinel-2 Level 2A satellite images, categorized as Analysis Ready Data (ARD), to investigate the impact of the Russia-Ukraine conflict on agriculture. The focus is on phenological changes in three designated zones. The eligibility criteria for the designated zones are determined by their proximity to the frontline, the significance of their agricultural sector, and the degree of direct impact experienced. These impacts encompass various factors such as city occupations, illegal annexation of territories, displacement of civilians, bombings, and international condemnations linked to these events. The processing flow involves the development of a QGIS model for automated operations, including NDVI calculation, image cropping, and statistical value computation.
The widely used Normalized Difference Vegetation Index (NDVI) is calculated using the Raster calculator algorithm
