on different approaches and data, and all have particular potential but also limitations  . The application of differing approaches shows that there is no single 'best' approach or data source to assess global progress on adaptation . Existing global assessments have provided valuable insights into the extent and types of responses and their level of planning and implementation . However, they do not provide comprehensive and robust answers so far on whether climate risk and vulnerability have been reduced  . As a result, combining different approaches and integrating data on climate risk levels, policy measures, implemented actions and their effects on climate risk reduction is currently regarded as the most robust approach  .
