The Adhoc Global Assessments Dialogue (AGAD) is an informal process that brings together the Heads of Secretariats, Co-chairs and selected experts of major global assessments with the main objective of exploring possible areas of synergy. The current main working areas of the AGAD are a) modelling and scenarios and b) glossaries and terminology. In May 2022, the AGAD decided to form a modelling and scenarios subgroup to share experience and discuss the current work areas of each assessment, and to explore possible avenues for collaboration.
