Air pollution has become the major problem of many cities, and it is affecting billions of persons around the globe. Airborne particles are known both to induce health problems and to have a role in climate change. Georesource-related particles account for a significant portion of the total load. Their emission occurs during the mining, recycling or use of georesources. We want to bring together communities working around georesources to propose a new methodology for assessing air quality through a participatory process. The aim of the project is to find a continuum from citizen involvement to the management of emissions. Our goal is to develop a passive sensor, with a low environmental impact, containing biological elements such as bark. This type of sensor offers the possibility for a large number of inhabitants to be active and play an empowering role in monitoring and assessing pollution, as well as being a means of raising awareness of environmental conditions. How citizens can become actors in the evaluation of their environment, and in particular of the air they breathe in connection with activities around georesources? We will set up a methodology to propose our bio-sensors and their implementation. The major stake of this consortium will be to imagine and develop a sensor or a declination of sensors combining the technical performance and the human aspect. At the same time, the design must allow its appropriation by the inhabitants by taking into account cultural diversity and representations of the measurement. Finally, a low environmental impact both in the manufacturing of the sensor and in its recycling is essential to disseminate this type of monitoring without causing additional pollution. To ensure the diversity of points of view and the consideration of the subject in its globality, our Think Tank is based on the synergy of partners involving organized civil societies, designer and researchers in anthropology, sociology, atmospheric sciences, geology, biology, epidemiology and geophysics.
