One of the key requirements for realising the potential of citizen science is evidence and demonstration of its impact and value. Based on a systematic review of 80 publications, combined with empirical insights from ten past and ongoing projects in the field of citizen science, a paper currently under review will present guidelines for a consolidated citizen-science impact assessment framework to help overcome the dispersion of approaches in assessing citizen science impacts; this comprehensive framework enhances the ease and consistency with which impacts can be captured, as well as the comparability of evolving results across projects. MICS's review is framed according to five distinct, yet interlinked, impact domains (society, economy, environment, science, and governance). Existing citizen-science impact assessment approaches provide assessment guidelines unevenly across the five impact domains, and with only a small number providing concrete indicator-level conceptualisations. The analysis of the results generates a number of salient insights which MICS combines in a set of guiding principles for a consolidated impact assessment framework for citizen-science initiatives.
Moreover, this recent paper has been published on the topic, providing a specific methodology for citizen-science cost-benefit analyses in flood risk management and concrete estimates of saving for a case study in Italy.
