At the request of the Government of Lebanon, the World Bank, in collaboration with the United Nations (UN), the European Union (EU), and the International Monetary Fund (IMF), has undertaken a rapid Economic and Social Impact Assessment (ESIA) of the Syrian conflict on Lebanon for the 2012-2014 period. The report's current (first) phase is limited to quantifying the impact and stabilisation needs of Lebanon. The ESIA is a rapid assessment, having been completed at very short notice, in light of the ongoing degradation of the situation. As such, while comprehensive in its aggregate (net) economic impact assessment, it provides a detailed assessment of selected, highly impacted, sectors.
