The SOCIO-BEE journey comes to and end and we want to share with you all the experiences learned together with our findings and results. Three years of work to develop a technology that empowers citizens by monitoring the air around them while assembling communities of informed citizens to change their behavioural habits and influence mobility planning in towns and cities with evidence. We want to share with you the technological development we have carried out during this time, as well as the countless engagement strategies we have deployed to facilitate these communities (our ‘hives’), to favour an effective change in their way of understanding and dealing with air pollution. We will also share, as a final reflection, the lessons learned during these 36 months of work and recommendations for working with citizen science methodologies to foster the assembly of these communities. If you work or have worked on similar projects, are interested in air monitoring or plan to work with communities using citizen science methodologies to bring about behavioural change, join us and participate in this event.
