31 Involve citizens, policy/decision-makers and other actors from the very beginning in story finding. This will help with identifying problems for different audiences/target groups, co-create hypotheses, designing the research process adapted to those problems, and collecting data that contributes to raising awareness and behavioural changes. Use co-creation tools and techniques to promote and strengthen shared ownership of the process and its outcomes and increase trust. Planning for involving citizens of a wide range of ages and cultural backgrounds is important to achieve a change in behaviour that is effective for awareness-raising from the grassroots of society and its influence on the family.

It builds upon the lessons learnt from previous projects such as Sound Map. Co-design was at the core of the process of installation, sensing and raising awareness about the issue of noise pollution in this area of the city. A series of participatory methods such as co-creation assemblies were included in a toolkit available on their website. See the full project
