City Dashboards are interactive web applications developed within the OneAquaHealth project to make environmental and research data easily accessible to citizens, researchers, and public institutions. Through an optimized search graph and intuitive visual interfaces, users can select a city and specific monitoring sites to explore indicators such as water quality, biodiversity, and pollution levels. By transforming scientific data into clear, visual summaries, the dashboards bridge research and public awareness, supporting evidence-based decisions for healthier and more resilient urban water ecosystems.
