The city of Roeselare is a municipality in West Flanders (Belgium). Residents have been experiencing abnormal droughts and intense rainfall in recent years, leading to catastrophic floods. The Flemish government awarded ‘The Smart in the City’ prize to the citizen science project Smartwaterland, which involved school students in building pluviometers to collect precipitation data to manage rainwater in a potentially smarter way . By involving students in measuring rainfall, families and other stakeholders could become more aware of the effects of climate change, and authorities could use the data for better planning. Smartwaterland was the first citizen science project coordinated by the city council in collaboration with other partners. Through the CitiMeasure pilot, the city aimed to boost the project’s potential in two key areas: communication and impact evaluation. The city aimed to strengthen the project’s communication efforts to raise awareness of data, targeting young and old people, agriculture and other businesses, and internal employees. In addition, there was a need for a tailor-made impact assessment matching the specific aims and ambitions of citizen science projects. 73 Boosting the potential of a citizen science project in Roeselare
