Dilek Fraisl on citizen science for policymaking
When countries set themselves ambitious targets such as the UN sustainable development goals, then realise they don't have the evidence sources they need to monitor progress towards those targets, how do they square the circle? In some cases, it's with so-called 'citizen science', in which non-professional scientists gather and evaluate data — often on a big scale — to fill the gaps. Dr Dilek Fraisl is an expert in using citizen science to address sustainability challenges. In conversation with Toby Wardman, she discusses both the value of using crowdsourced data, and the challenges that arise when presenting it to policymakers.
