The Food and Agriculture Organization of the United Nations (FAO), in partnership with the Ministry of Agriculture in Lebanon, conducted a household survey between 31 October and 30 November 2023 using computer-assisted telephone interviews. These interviews were part of the FAO Data in Emergencies Monitoring (DIEM-Monitoring) System which monitors the impact of shocks on agricultural livelihoods and food security. The survey targeted the agricultural population using the sampling frame of agricultural holdings from the 2010 Lebanon Agricultural Census. Additional survey questions were added to assess the impact of the escalating hostilities in southern Lebanon on farmers’ agricultural livelihoods and food security. FAO established Data in Emergencies Impact (DIEM-Impact) to provide a granular and rapid understanding of the impact of large-scale hazards on agriculture and agricultural livelihoods using a variety of assessment methodologies, including primary and secondary information, remote sensing technologies, and FAO’s damage and loss methodology. DIEM-Impact presents a regularly updated and accessible state of food insecurity in fragile environments and helps underpin FAO's programming based on evidence.
