evaluating Algorithm performance in image processing and data analysis
Using publicly available imagery capabilities from NASA's MODIS satellite, which provide detailed coverage at a 30m x 30m scale across agricultural regions in Ukraine, we leveraged advanced algorithms through Google Earth Engine to generate insightful time-series charts showcasing the annual mean NDVI (Normalized Difference Vegetation Index) from 2021 to 2023.

The chart reveals a notable decrease in NDVI for 2022, attributed to heightened warfare activities. Our comprehensive statistics validate the consistency of our findings across the years, aligning closely with Google Earth Engine's data, especially in June 2021 and 2023.
While the results for 2021 and 2023 slightly decline, they still surpass the NDVI values observed during other months of the year. These findings underscore our commitment to delivering accurate and relevant insights through advanced technological methodologies.
NDVI: 0.3526 Location: 47°30N, 36°28E
Based on our findings, the area with a higher NDVI (significantly darker green than its surroundings) could be due to conflict-related issues, such as a lack of workers and fuel during active warfare. Additionally, grazing restrictions might lead to overgrown vegetation in these areas.
These disruptions, including infrastructure damage and farmers' displacement, could potentially lead to food shortages in affected areas.
NDVI or overgrown crops can help us predict famine risk caused by conflict-related destruction of agricultural areas. Our findings indicate that lower NDVI is linked to decreased crop yield.
