Citizen science often involves collecting environmental data – but data alone is not enough. For citizen science to truly make a difference, that data must be transformed into actionable knowledge: information that can influence public debate, raise awareness, inform decisions, and ultimately drive policy and structural change.

In this module, we briefly unpack the challenges and opportunities involved in producing actionable knowledge through citizen science. We’ll explore key concepts such as:

• Legitimacy – whose voices and knowledge are recognized as valid?

• Credibility – how can trust be built around citizen-generated data?

• Uncertainty – how should we manage and communicate it in science and society?

Through two short videos you’ll learn that actionable knowledge is not just about collecting accurate data, but also about navigating the complex social, political, and emotional dimensions of knowledge production.  By the end of the module, you will have a deeper understanding of how citizen science can bridge the gap between research and action, and how it can help empower communities to address environmental and health challenges in meaningful, transformative ways. 

This module contains two video lectures, one on the definition of actionable knowledge in citizen science, and one on the challenging dimension of actionable knowledge: legitimacy, credibility and uncertainty.
