The D-NOSES project launched the OdourCollect app earlier this year that enables citizens to map odour issues they encounter in their communities. Until now, 6 of the pilots chosen to demonstrate the ability of Citizen Science to get results in different contexts have started in diverse locations.
In some cases, the pilots focus on different types or odour sources. In Barcelona, Spain, the affected area has a history of odour issues from waste management facilities. This has been a growing concern, particularly since the municipality tried to revitalise the area with new high-end developments and housing. In Thessaloniki, Greece, residents are persistently exposed to fumes from the nearby refinery. Both cases show how an accommodation needs to take place as communities and industries develop over time. The balance between industry, economic and social development, city planning, and environmental management is one D-NOSES can help achieve.
Using the D-NOSES stakeholder engagement model, the pilot in Sao Joao da Madeira will tackle a persistent odour problem from an animal by-product processing plant. In this case, there have been previous volunteer-based odour mapping projects that unfortunately did not result in any practical improvement of the situation. This pilot should demonstrate that not only data, but also positive engagement of all stakeholders is required to find balanced solutions.
In Sofia, D-NOSES will help diagnose and explore more cost-effective performance improvements for the existing municipal program to eliminate odours from food waste around the city. In Porto, volunteers will help to trace odours that could reveal the sources of pollution in the Rio Tinto river so that they can be stopped and help reverse the environmental damage. Both these pilots demonstrate the flexibility of the approach to deal with a wider range of issues relating to the impact of odour pollution.
