Synopsis (short abstract) 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.

    Greenhouse damage assessment during the conflict across Lebanon in 2024 2025

    A geospatial damage assessment was conducted to evaluate the impact of the 2023–2024 conflict on greenhouses in Lebanon. The assessment utilized very high-resolution (VHR) satellite imagery from WorldView-2 (50 cm) and WorldView-3 (30 cm), comparing images from before October 2023 and 2024. This assessment covered four of the most conflict-affected governorates. Using VHR imagery, visual interpretations were conducted in those governorates to assess the damage of the greenhouses. While the map depicts the distribution of damaged greenhouse areas using a hexagonal grid for the two visual interpretations, the graph illustrates the proportion of damaged greenhouses relative to the total intact greenhouse area by governorate. Overall, a 3.4 percent difference of damaged greenhouses was observed between visually interpreted points and delineated greenhouses. Two independent assessments were conducted with less than 3 percent difference.
