Beyond causing immediate hardship and triggering a large exodus of displaced people, Russia’s military invasion of Ukraine and the blockade of its Black Sea export routes have also led to sharp increases in grain prices and raised concern about global food security. To provide information to the government for developing policies and programs to support the agricultural sector in Ukraine, the World Bank launched a nationwide survey of post-invasion farmers in cooperation with the Ministry of Agricultural Policy and Food (MAPF), with financial support from the EU, in areas controlled by Ukraine from October to December of 2022. The survey objective is to obtain information on changes in welfare, production, and productivity in the small and medium farm sector between 2021 and 2022 and to identify ways on how farmers could be most effectively supported. Data was collected via phone by the Kyiv International Institute of Sociology (KIIS) under the monitoring of World Bank research team.
