The webinar will cover methodological elements and practical applications of knowledge management as part of actions supporting policymakers in system mapping and policy co-design processes. In doing so, this webinar seeks to highlight applications and synergies with monitoring, evaluation and learning activities. The webinar will illustrate the broad context of policy mix and EU Framework, the case of Transitions Hub as a policy lab managing knowledge management processes as well as related examples on system mapping and policy co-design processes. This material is based in the Handbook Challenge-led system mapping, a knowledge management approach.
