While relatively few countries to date have designed and implemented a national system for adaptation monitoring and evaluation, many more have indicated in their Nationally Determined Contribution (NDC) that they are working on developing one, or intend to do so._________________________________________________ Evaluations are partly based on the information monitored, but also draw on other relevant information such as stakeholder consultations and expert reviews. The monitoring and evaluation can take stock of the implementation of adaptation measures, which can spur learning on their effectiveness.
