The European Citizen Science Association developed the 10 ECSA characteristics through a vignette study, a survey method that captures different perspectives on complex issues. ECSA then reviewed its 10 Principles for Citizen Science, a comprehensive framework for best practice in citizen science, to identify its gaps and limitations and how the ECSA characteristics can help address them.
The findings highlight the disciplinary differences as well as the ambiguities associated with different citizen science practices. There are two challenges in defining citizen science. A very strict definition could exclude valuable practices, hinder innovation and discourage public participation. Conversely, a loose definition could make it difficult for certain target groups to apply it effectively in their own context. It is therefore beneficial to adopt an inclusive approach and language that allows the target group to define their own criteria according to their needs, purpose and specific circumstances.
The ECSA characteristics were developed in a spirit of openness; the identification of areas with different and even conflicting views was a central element of this practice. We recommend their use in their entirety and believe that no one area or characteristic is more important than another. They should be viewed as a toolkit of examples that can guide efforts to define citizen science for a particular context and purpose. They build on the 10 ECSA principles and address some of their gaps and limitations, while recognizing the need to update and improve the 10 principles based on developments in the field.
