The overarching objective of the evaluation was to assess the effects of humanitarian assistance, both at the household level and more broadly on the economy in Idleb. At the household level, the primary aim was to determine if assistance was successful in maintaining food security. At the District and Governorate levels, the evaluation aimed to assess the impact of humanitarian assistance on markets and also to compare the economic effects of different transfer modalities, including vouchers and in-kind assistance. Trends in prices over time, market concentration and multiplier effects of food assistance are quantified. The cost efficiency and cost effectiveness of different transfer modalities was also compared.
