This document discusses the role of regional and international reports in assessing collective progress towards long-term adaptation goals. It outlines that reports from organizations like the IPCC, UNFCCC, development partners, and regional organizations can provide information on adaptation efforts, policies, projects, and good practices. However, it notes that evaluating the adequacy and effectiveness of adaptation and overall progress faces challenges due to lack of specific adaptation targets and indicators, data gaps, and uncertainty around sustaining regional activities. The document recommends disseminating global stocktake guidelines, focusing more on adaptation at the basin scale, and promoting understanding of adaptation costs and benefits.
