This document is the third iteration of the Flash Appeal for Ukraine, which was originally published on 1 March 2022 and revised once in mid-April. This updated Flash Appeal covers the period of 10 months following the onset of the war in Ukraine that started on 24 February 2022 (i.e., from March to December 2022). The financial requirement of this Flash Appeal reflects the humanitarian needs from March until the end of 2022, taking into account the funding status and the response achievements to date, as well as the realistic projection of response capacity in the second half of the year. The smaller set of prioritized activities outlined in the “Winter Priority Procurement and Repair Plan,” which was released at the end of June 2022, have been folded into this Flash Appeal and complemented by other critical winterization and winter-specific interventions. These include (but are not limited to) cash for accommodation and utilities, cash or agricultural inputs for farmers to support winterization, heating system repairs, etc. This update of the Ukraine Flash Appeal will be the last iteration in 2022.
