Citizen science communication and engagement: a growing concern for researchers and practitioners

Anniversaries provide great opportunities to celebrate achievements, to look into the future, and to do some self-reflection. I have the honour of doing so in a specific field of science communication that I’m familiar with: the field of citizen science communication, especially with a European focus. I hope this commentary prompts others who are experts in their regions of the world to also reflect on the past and the future for this growing field.
