    A geospatial damage assessment was conducted to evaluate the impact of the 2023-2024 conflict on greenhouses. To establish a greenhouse baseline for 2024, Sentinel-2 satellite imagery with a resolution of 10 meters was utilized. Approximately 3,000 training data points were collected using Very High Resolution (VHR) satellite imagery from WorldView-2 (50 cm) and WorldView-3 (30 cm), along with Google Earth data and existing greenhouse area delineations for four governorates. Separability metrics were calculated for various indices, such as the Plastic Greenhouse Index (PGHI), Advanced Plastic Greenhouse Index (APGI), and Plastic-Mulched Land Cover Index (PMLI), using seasonal composites. The remote sensing analysis achieved an overall accuracy of 94 percent. Additionally, visual interpretation with VHR imagery was conducted in the four governorates. The resulting map illustrates the distribution of greenhouse areas using a hexagonal grid format, while the accompanying graph depicts the proportion of greenhouse areas by governorate.

    Utilising a baseline greenhouse layer prepared by FAO in 2021 and very high resolution 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. A thorough evaluation of damage to greenhouses was performed, comparing pre-conflict imagery with very high-resolution WorldView-2 imagery from 18 April 2025 and WorldView-3 imagery from 28 April 2025.
