Presentation Open Access
This presentation summarises the concept of "policy engagement" used in the 3-year project Doing-it-Together science (DITOs). I present the understanding of policy engagement developed by the European Citizen Science Association (ECSA), which led the policy engagement work in DITOs, activities carried out and some impacts. Three main lines of work are highlighted: (1) Anchoring CS in EU research policy, (2) Supporting capacity building of national networks and (3) Developing more open organisations. The presentation was made at the 2019 meeting of the COST Action 15212 with the aim to make results available in discussions on the state of national CS strategies in COST countries.
