Brief communication: Storm Daniel flood impact in Greece in 2023: mapping crop and livestock exposure from synthetic-aperture radar (SAR)

Abstract

For this brief communication, we analyzed the crop area and number of livestock exposed to flooding from the historic precipitation caused by Storm Daniel in central Greece on 3-8 September 2023. We derived from the nearreal- time RAdar Produced Inundation Diary (RAPID) system an inundated area totaling 1150 km2, located mainly in the Thessalian plain. By overlaying a land cover map on the RAPID inundation map, we found that ∼820 km2 (70 %) of the inundated area was agricultural land. A detailed distribution map of crop type and animal farms revealed that the crop most affected by the flooding was cotton; the inundated area of more than 282 km2 comprised∼30%of the total area planted with cotton in central Greece. In terms of livestock, we estimated more than 14 000 ornithoids and 21 500 sheep and goats were affected. Consequences for agriculture and animal husbandry in Greece are expected to be severe.
