This addendum, Communicating The Key Learning: A Crucial But Often Neglected Step Version 1, is an update to the Global Coral Reef Monitoring Network (GCRMN) Socioeconomic Manual for Coral Reef Management (Bunce et al. 2000). The addendum was developed by the Centre for Resource Management and Environmental Studies (CERMES) at the University of the West Indies, Cave Hill Campus, Barbados – the regional SocMon node for the Caribbean – due to the recognized shortfall of the GCRMN SocMon Manual in emphasizing the importance of communicating the findings from socioeconomic monitoring and using them in decision-making in adaptive management, which is an aim of the monitoring process. Globally, other SocMon regions have also recognized this deficit in the GCRMN SocMon Manual and as a result have added A Key Learning and Communication step to SocMon trainings. The additional step can be developed further and adapted based on regional needs.
