"Priorities for the UN's Children and Armed Conflict Agenda, 2020" is the final report from LISD's annual workshop co-organized with the NGO Watchlist on Children and Armed, and held on January 29, 2020. The report reflects the discussions from three closed working sessions dedicated to (1) ongoing challenges and concerns impacting the implementation of the CAAC agenda, (2) emerging concerns and trends for the CAAC agenda, (3) the role of Member States in advancing the CAAC agenda through the Security Council Working Group and Group of Friends. A final recommendations section reflects findings from the workshop's wrap-up session which summarized key discussion points and recommendations of the working sessions. The report was issued as an official UN Security Council document (S/2020/406).
