The document discusses different approaches to measuring adaptation to climate change, including: 1. Measuring vulnerability to identify needs for adaptation, inputs and outputs of adaptation actions, and their effectiveness, though vulnerability assessments are difficult to compare across regions. 2. The IPCC's framework which conceptualizes climate risk as hazards, exposure, vulnerability, and impacts, and the scope for adaptation and risk management, though attributing risks to climate change is challenging. 3. Mixed approaches that track both the process of adaptation and outputs across scales through methods like institutional scorecards and resilience measurement tools. Overall, adaptation is occurring but progress is not well observed, metrics are evolving, and combining qualitative and quantitative process- and
