Reconstruction monitoring in Beirut, Lebanon, following August 2020 explosion, for the Reform, Recovery and Reconstruction Framework (3RF) (2021-03-10)

Activation date: 2021-03-10
Event type: Industrial accident

Activation reason:

The explosion of a large amount of ammonium nitrate stored in a warehouse in the port of Beirut on the 4th of August 2020, had a devastating outcome not only for the port area but affecting larger areas of the Greater Beirut Area, reaching kilometres inland. The Reform, Recovery and Reconstruction Framework (3RF) has been developed by World Bank Group, United Nations and European Union, bringing together the civil society, the government and the international community in order to provide a roadmap to move forward to ensure that people’s needs are addressed through a combination of socio-economic recovery and reform. EMSN087 provides the 3RF with data and information on the baseline damage assessment with the reference date of February 2021 and subsequent six monitoring assessments of the reconstruction progress on a quarterly basis, beginning in April 2021 until July 2022. While satellite imagery data serve as the primary information source, ancillary data were made available aby UN-Habitat Lebanon. A damage assessment was conducted in a field survey after the explosion by UN-Habitat and the Municipalities of Beirut and Bourj Hammoud and was supported by the Rotary Club Beirut Cedars. The data were used for cross-checking purposes of the damage assessment based on the satellite imagery of February 2021.February 2021 status - baselineDamage assessment on building footprint levelThe damage assessment was conducted on building footprint level incl. a focus on industrial areas or facilities of public interest. The assessment was based on a visual inspection of comparing satellite images with a temporal coverage of pre-event, immediate post-event and post-event imagery of the reference date of February 2021. A photointerpretation key (PIK) was developed serving a guide to the imagery analysts to assign the damage grade to the building and allow the user to understand how the damage grade analysis was conducted. The classification is based on the following grading classes:Destroyed (Very heavy structural damage total or close to collapse)Damaged (Visible Structural and non-structural damage)Possible damaged (Uncertain interpretation due to reduced visibility)No visible damage (No visible damage in the satellite imagery data)Under reconstruction (already under reconstruction)New building (not existing before the explosion)Not analysed (due to e.g. cloud coverage, building shadow)Statistical analysisThe results of the analysis show that for the vast majority of the buildings no damage visible damage could be determined based on the visual analysis of the satellite imagery with the reference data February 2021.
