Fig. 1. (a) Map of conflict events in ACLED dataset in 2020 and 2021. (b) Timeline of events in ACLED database. The crop calendar and timeline of key political events are shown at the bottom, including the official start of the war in November 2020. Fig. 2. Process diagrams for creating annual cropland maps and computing area estimates. Map images are for illustration purposes and do not represent actual results. Fig. 3. Left: 12-month time series of Sentinel-2 NDVI for ground-truth plots annotated as cultivated (“Crop”), fallow with weeds (“Fallow Weed”), or fallow with no vegetation at all (“Fallow None”). Solid lines depict the mean and shaded regions depict the standard deviation of the time series for all samples. Right: Visualizations of example ground-truth plots in PlanetScope September 2021 basemap. The plot labeled “Fallow with weeds or grass” has a similar appearance to fields labeled with crop types, while the field labeled “Fallow (no vegetation at all)” is easier to disti
