While there are many definitions of citizen science, the term usually refers to the participation of the general public in the scientific process in collaboration with professional scientists. Although this approach has so far been primarily undertaken in the environmental domain, recent promising experiments have demonstrated its potential for addressing complex societal problems at the interface between public health and the environment.

OneAquaHealth aims to identify early warning indicators and enhance environmental monitoring with digital tools such as a Citizen Science App, to raise awareness and engage all relevant stakeholders to jointly achieve thriving ecosystems and healthier communities for the future. Thus, citizen science has a pivotal role in OneAquaHealth participatory research approach and contributes to shape the way in which data will be collected, shared, and used in the project to deliver accurate monitoring and decision support tools.

OneAquaHealth aims to collaborate with projects and initiatives that tackle similar issues to promote healthier communities. Therefore, OneAquaHealth project and and Wise Angle Consulting S.L (OneAquaHealth work package leader) were delighted to invite you to a webinar dedicated to share experiences and viewpoints on the most successful engagement strategies in Citizens Science projects and the usage of Mobile Applications. This webinar covered two main themes. The first part focused on Citizens Science Approaches, featuring presentations from publicly funded projects, namely OneAquaHealth, DRYvER, and E4WARNING. Specifically, it explored how these projects have engaged with citizens to achieve successful participation for the collection of feedback, which is crucial for the development, diffusion, and utilisation of the projects’ digital tools. The second part delved into Mobile Apps – Challenges and Solutions, with presentations from PHArA-ON and Invasoras.pt Apps, exploring common hurdles faced in promoting the apps or designing them to be user – centric.
