  War-related disturbance of agricultural land can alter crop development by changing soil physical conditions and surface structure. This study used a nine-year sentinel-2 time series (2017-2025) to examine vegetation responses in farmer-managed fields affected by military activity. Normalized Difference Vegetation Index (NDVI), Green Normalized Difference Vegetation Index (GNDVI), and Normalized Difference Moisture Index (NDMI) were analyzed to characterize changes in canopy development and moisture conditions and to identify spatially persistent anomalies within the fields (Kherson region). The analysis showed that the strongest departures from earlier spatial patterns occurred in 2024-2025, when localized areas of reduced vegetation and moisture indices became more pronounced. These patterns were associated with sectors exposed to military disturbance, including vehicle movement and.. Read More»
