This review provides insights into how to evaluate the impact made by knowledge created by CREW activities and whether such impact leads to improved environmental, social and economic outcomes via evidence-based water management. It is widely recognised that impact is more likely to occur when research is co-constructed with research users and is designed with a specific context and use in mind. Knowledge needs to be produced via engagement of researchers and policy makers throughout the policy and research processes, and the outputs communicated in the right way, at the right time, to the right people to produce outcomes which may have an impact. Dissemination of research is not in itself sufficient to have impact.
