BiodiverCities Atlas: A participatory guide to building urban biodiverse futures presents case-studies from the BiodiverCities project and several reflections on how to meaningfully engage citizens in the making of more liveable cities. This Atlas is a collection of stories. Stories of big, small and medium-size cities, with many or few green spaces, with a stronger or weaker culture of public participation that engages citizens in the design of public policies. These are stories of civic and political engagement - to do better, at times to do different, but mostly to do together. You will not find grandiose tales narrating transformative successes. You will find stories of civic, political and research experiments, accompanied by critical reflections. There are ten stories as ten are the cities that took part of the BiodiverCities project: Palermo, Valongo, Maribor, Leiden, Lisbon, Vilnius, Varese, Novi Sad and Palma.
