Faced with the increasing and irreversible impacts of climate change, a growing number of public and private stakeholders across vulnerable sectors are engaging in adaptation efforts. However, our knowledge is limited regarding the types of information being demanded in order to track adaptation progress nationally. To address this gap, we conducted a needs assessment of 191 public and private stakeholder organizations. Stakeholder needs are classified into fourteen themes, encompassing measurements in implementation, outcome and learning, data availability and methods, and crosscutting aspects. With approximately half of organizations surveyed expressing a need for adaptation tracking, we conclude that there is significant demand for: 1) translating climate risk data into impacts and damage costs; 2) monitoring institutional and policy coordination and coherence; and 3) evaluating adaptation outputs and outcomes to inform decision-making.
