Greenhouse damage assessment
Utilising a baseline greenhouse layer prepared by FAO in 2021 and very highresolution satellite imagery*, UNOSAT updated the baseline for 2023, prior to the recent conflict escalation, and conducted an assessment of the number and area of greenhouses in the Gaza Strip. WorldView-2 (50 cm) and WorldView-3 (30 cm) imagery from 1 May 2023, 10 May 2023 and 18 September 2023 were used for pre-conflict imagery. A thorough evaluation of damage to greenhouses was performed, comparing pre-conflict imagery with high-resolution Worldview-2 imagery (50cm) from 23 April 2024. The area of damaged greenhouses was calculated by overlaying the greenhouse distribution layer with the damage layer (damage proxy map). The grid depicts the severity of damage in localised areas; in each tile the area of damaged greenhouses was divided by the total greenhouse area.
