What is the name of your initiative?
DIAMS – Digital Alliance for Marseille Sustainability
Please provide a short description of your initiative* (What is being done? Who is participating? What are your main goals?) This text will appear on the main page.
The DIAMS project has 4 main objectives reflecting the five senses of human brain:
– Perception: To improve air quality information and produce high quality, detailed data
– Balance: To promote a fluid transmission of territorial data and air quality data between urban, regional and national platforms and ensure their consistency.
– Creation: To stimulate creativity and harnessing the expertise of citizens and the private sector to co-develop and implement innovative solutions to improve air quality.
-Movement: To provide personalized and adaptable information to citizens and policy makers to encourage their awareness and engagement.
In concrete terms, the DIAMS project consists in deploying a platform for the exchange of data on air quality and digital services that allows everyone (political decision-makers, experts, citizens, civil society, economic actors, for example) to commit themselves to developing coordinated action plans at all territorial levels (individual, hyper local, urban, regional, national and supranational).

• Use existing tools and modify them to respond to the problems and needs identified : “Do not reinvent the wheel”
• Identify the needs with the local actors (you need to be accompanied by animation experts)
• Take account cost due to: controling quality by air expert, analyzing data (150€/unit), Machine learning (50 000€), personalizing assistance (call center – 10 000€ for 2000 citizen sensor), Logistic for the citizen sensors distribution (70€/unit)
• Be prepared to rewrite and update the digital architecture (consult with expert developers)
• Be trained by those who have made the tools (via a remunerated service)
• Take account the maintenance due to issue of updated operating system (iOS, Android…)
• Create new functionalities and realized the needs by trusted expert (developer).
• Integrate machine learning to filter and correct the data
• Work on the governance of partners and providers with a good animation. Identify trusted collaborators. Be present in the field. Identify the right vectors: schools, field agents, federations of associations, town hall manager. These actors must be the driving force.
• Work on the governance of data and on the licenses of common goods.
