The pilot site is Taranto, in Apulia, southern Italy, with a focus on the area surrounding the former ILVA steel plant, now Acciaierie d’Italia. The plant is located close to urban neighbourhoods, including Tamburi, and to the Mar Piccolo/Mar Grande coastal system, making Taranto a highly exposed industrial port city. For decades, the area has been affected by air, soil and marine pollution linked to steel production, with documented concerns over emissions, dust deposition, contamination, health impacts and the protection of residents’ rights. The case has also been examined by European courts in relation to environmental and health protection. The pilot will potentially involve local residents, schools, civic committees, environmental organisations, health professionals, local authorities and community groups interested in accessible monitoring tools, environmental data literacy and participatory evidence-building.
