This document outlines a framework for developing priorities for climate change vulnerability, impacts, and adaptation (VIA) research. It identifies the main audiences for this research as policymakers and experts. It describes activities to identify VIA research priorities from both policymaker and expert perspectives, and then integrate those perspectives. The proposed framework focuses research on supporting policymaker activities like identifying problems and solutions, estimating costs and benefits, and enhancing communication; as well as key systems, human well-being, critical geographical areas, and emerging issues. A total of 33 priority topics are identified.
